Indeed, quite sad. One gets quite invested in a career/boat after that many patrols and knowing had one more before sailing back to US ( I have that implement in the sim for classes withdrawn before end of war, some dangers possible along the way to keep things interesting) . Of course can't say for sure but am confident that had been in a more modern boat that could submerged faster, go deeper, was more maneuverable under water, probably could have survived, not been hit by the hedgehogs but NAUTILUS was essentially a sitting duck.

Default USS BARB SS-220 8 January-14 February 1944 in Area 8

TMO Update V2.0
100 difficulty
cams off, map contacts on (for this patrol)


With the loss of NAUTILUS due to friendly fire after 14 patrols. Decided
wanted to get back into the thick of things and test out some stuff in a 1944 career. So got a GATO and randomly assigned USS BARB SS-220 which I was happy with. BARB is the subject of many "historic contacts" , traffic I added to campaign, based on real ships, which can be located and sunk at or near
the actual dates and times of sinking by a particular sub.

Since started in Jan 1944, which is before the skipper would who make her famous (Fluckey) took over, I started the career under her previous skippers name and took the objectives assigned. I plan to change the name etc when appropriate time period comes about. BARB was assigned to Area 8 for this patrol, a prime area especially in 1944. This was one of the new patrol objectives I added to campaign.

WEATHER

Weather en route to patrol area and while in area was calm, warm, and comfortable for most of the patrol.
While in area for a few days seas did increase with 4-6 foot waves, winds 17-18 knots. Moonlight was
on most night almost nonexistent providing ideal conditions for night surface attacks.

Some squalls and rough seas were encountered en route to Pearl Harbor from assigned area but
nothing unusual.


ATTACK DATA


Five torpedo attacks were conducted on this patrol, with a total of eighteen torpedoes fired
for seven ships sunk.All torpedoes functioned properly to our knowledge. Four of five attacks conducted
were on the surface, at night against convoys. Submerged day attack was made on convoy previously attacked
during the night. A attempted submerged night time attack was made, but a alert escort detected BARB
and prevented attack.

MINES

No enemy mines were encountered


NAVIGATIONAL AIDES

Sofu Gan served as a navigational aid. Otherwise the open sea area provided
no aides.


THERMAL LAYERS

Thermal layers were encountered at 195 feet
and 270 ft.



SOUND CONDITIONS AND SOUND GEAR

Sound conditions were generally favorable in patrol area.

Sound gear functioned well, with a marked decline due to damage taken
in depth charge attacks.



RADAR

SJ

Newly installed SJ-1 Radar and PPI scope worked well in detecting and tracking convoys.
As a policy, SJ sweeps are conducted every quarter hour when on surfaced.
Typical detection range was about 25000 yards.

SD

SD Radar function was adequate, although appears to have difficulty tracking
aicraft beyond 10000 yards when at altitudes at altitude of 1000 feet or less.


RADIO

Radio function was normal throughout patrol.


ANTI-SUBMARINE COUNTERMEASURES AND EVASION

Countermeasures

Overall, enemy ASW measures were standard. Each convoy encountered had two escorts. Lead escort made sweeps to each side of
the convoys path forward roughly every fifteen minutes, aft escort did the same, but often
conducted sweeps 5000-10000 yards to the rear quarters of the convoys. Rear escort is typically a DE
or in our case Otori class torpedo boats, capable of high speeds to conduct this manner of escort and patrol.

Enemy aircraft were encountered almost daily in patrol area, with one called in following a series of attacks
on 26 January that left four enemy ships sunk, out of six in the convoy (not including two escorts). This aircraft
was a night flyer and most likely had radar as it closed in on BARB , forcing a dive. Explosions of bombs were heard above,
indicating BARB was detected beyond visual range , at night.

Night flyer, possibly equipped with radar were encountered en route to area as well. Following a attempted attack
on a weather tug off Sofu Gan, in which a BETTY that was in area spotted BARB at periscope depth during approach
and bombed us. For two days and nights aircraft flew in the area along our base course, forcing several dives, and were
bombed nearly every time, even at night. Again, the pinpointing of our location beyond visual range,
in particular at night, indicates aircraft armed with radar.

Open ocean patrols by teams of first line Destroyers were
contacted, indicating a strengthened ASW presence, along with aircraft in the vital sea
lanes in which BARB was assigned.


Enemy depth charge attacks were effective on this patrol. Japanese escorts appear to be equipped with
new, more powerful depth charges along with improved sound gear. Team tactics including
attacks in rapid succession were used by enemy in both attacks. After some time, one would rejoin convoy while
other kept submarine pinned down permitting their charges to open the range for escape.

While the ASW vessels were effective, a major flaw is neigh kept their attacks beyond a few hours,
departing to rejoin. This is particularly true for the second attack on 28 January, as BARB had serious damage, the early termination of the attack provided much needed relief.


Evasion

Evasion of enemy aircraft consisted of a dive to 150 feet for 30-90 minutes, followed
by a sweep at periscope depth with SD via extended mast.

Forces hunting for BARB following encounter off Sofu Gan were evaded by a course change and high speed run further South-East into southern part of
area in lieu of maintaining base course. This tactic proved successful as there were no more contacts until reached assigned area.

Evasion of depth charges consisted of diving to 300 feet, rigged for silent running,
with five to degrees rudder applied to port or starboard at nearly all times, this served
to confused enemy as to our exact heading. After first run, BARB descended to 350 ft, then 375 ft.
These left typically charges or most exploding above the BARB.However, BARB was forced to 390 feet to get
below the enemy's sonar and depth charge patterns.
Once at 390 ft, the enemy appeared to have difficulty, overall, tracking BARB.

When a enemy would be directly above, a "burst" of speed would by used by ordering
'Ahead Flank' for thirty seconds, reducing to ahead standard and then back
to 1/3 after thirty seconds.

PERSONNEL

Crew of the BARB performed well throughout a busy and challenging patrol.
Eight men advanced in rating during this patrol
Eleven men qualified during this patrol.

QM2c John C. Clark was wounded by machine gun fire during night surface attack.
Clark was on the bridge as a forward lookout beside the Commanding Officer and Battle Stations OOD when just after torpedo impact, during BARB's turn away, a barrage of machine gun fire hit the forward deck with a few rounds hitting the lower shears and bridge area.
Although wounded, Clark remained at his post until relieved and overall had recovered by the time BARB returned from patrol.


HEALTHY AND HABITABILITY

Crew morale and health on the patrol were excellent. No doubt this was assisted
by well prepared meals, generally pleasant weather, and the sinking of seven enemy vessels.

Factor in Termination of patrol-Damage
Both periscopes damaged beyond repair.


REMARKS

A highly successful patrol, BARB's best to date with seven ships sunk. Area 8 proved to contain vital
North/South sea lanes. Three convoys, two Southbound and one Northbound were encountered in the within five days of one another in patrol area. Enemy air and surface patrols, along with escorts
protected these convoys well. Enemy frequently uses zigs and course changes to thwart attacks.

Finally, the it is regrettable BARB had to depart early for home with six torpedoes left (four forward, two aft) due to irreparable damage to both periscopes, but BARB and her crew remain proud of what were able to accomplish in just nine days on station.

ANTI-SUBMARINE COUNTERMEASURES AND EVASION

Anti-Submarine Countermeasures

Enemy ASW in area was conducted mainly via air patrols, encountered on a near daily basis.
Nearly all were radar equipped. Distress calls for convoys under attack at night brought in
radar equipped air support at dawn. APR-1 Radar Warning Receiver installed during refit after last patrol
proved a great asset in mitigating effects of these patrols.

North of Wake and Marcus Island air patrols equipped with radar harassed BARB daily during transit to and from
patrol area.


One enemy escort vessel was known to be equipped with radar, which proved useful in providing some idea of BARB's location on surface.

A patrol of two DE type vessels encountered on en route from patrol area East of Iwo Jima in
area DUNKERS DERP (see contacts) produced radar emissions detected by APR-1. Both vessels
appeared to have radar. Both enemy convoys attacked on this patrol had what no appears to be the standard two escorts, one forward, one aft, with each making
sweeps. All merchant vessels appear to be armed, some heavily.

Depth Charge attack experienced by BARB on this patrol was fairly standard by proved effective in damaging
the boat. After sinking two tankers via periscope at night, submerged. Each escort, unaware of BARB's location stopped and listened.
BARB was at least 4500 yards from each but their search detected us. Both vessels rushed our location. BARB was at 350 feet, rigged for silent running and depth charge, when first depth charges exploded, well astern of us, apparently the escorts attacked a false contact.

However, a few minutes later pinging began and BARB was located. Each escort took turns in rapid succession making depth charge attacks.
These escorts are believed to have the improved depth charges encountered on recent patrols.
After several tooth shaking patterns, a closer one caused serious damage (see MAJOR DEFECTS AND DAMAGE) to BARB, but all was repaired in due course at sea.

However, again a fatal flaw in Japanese ASW escorts, is to give up too soon. After the pattern that damaged,
enemy seemed to give up as one was heard rushing away to rejoin convoy. Other went silent, likely to listen for BARB.
BARB crept away at 390 feet, with water in control room and forward torpedo room. This flooding plus a damaged trim
pump made depth control a challenge at times, requiring some extra speed. A one point BARB descended to 404 feet.

Overall, enemy sonar gear, depth charges, and ASW tactics have dramatically improved in recent months.


Evasion


Evasion for BARB was standard with previous patrols. BARB, if detected by aircraft, upon surfacing would change
course and speed to thwart any searches along course steered when detected.APR-1 was found to often detect aircraft, if their radar sets were on, before SD radar detected them.
This provided early warning and a dive was made at least once when SD failed to detect what was believed a low flying
radar equipped aircraft.


Evasion of enemy depth charges was made with utilizing thermal layers, frequent speed bursts, course,
and depth changes.

Evasion of enemy following night surface attack consisted of turning away slowly during torpedo run
and just moments before, ordering flank speed and departing area, at times under fire.



MAJOR DAMAGE AND DEFECTS

No major material defects.

Damage

Depth Charge Attack No.1

BARB suffered serious damage during depth charge attack, but all damage was repaired at sea.


1.Flooding in control room and bilges due to numerous busted sea valves.
One foot of water in compartment.

2.Flooding in Forward Torpedo Room due to shear dogs on hatch, leaks in damaged
torpedo tubes, and busted sea valves. Two foot of water in compartment.

3. No.3 Torpedo Tube

4. No.5 Torpedo Tube

5. Trim Pump

6. Hydraulic Pump

7. Forward Batteries

8. Aft Batteries

9. Compressor

10. Radio Transmitter

11. No.2 Electric Motor

12. No.4 Electric Motor

13. Dives Planes Transmission-Bow and Stern

14. Fuel Oil Tank-Leak

15. Compressed Air Reserve- Twenty five percent of capacity lost due to damage,

but repaired and replenished.


16. Leaks in piping and vales throughout all compartments

17. Leaks in high pressure air lines throughout all compartments.

18. Glass fixtures and light bulbs in all compartments



RADAR

SJ

SJ Radar performance was overall excellent. Typical
detection range of surface targets was 25000 yards.


SD

SD Radar performance was overall acceptable. Typical detection
range was 12000 yards.

Enemy

Enemy air based surface search radar appears to have a range of at least 30000 yards.
Enemy aircraft do not always have the set active, but appear to alternate on and off searching area.
Night flying aircraft tend to keep radar on at all times as those encountered in hours of darkness on this patrol previous demonstrated behavior as such. On this patrol APR-1 was able to confirm presence of radar.


Enemy escorts equipped with radar did not appear as effective was was on surface and within 5000 yards of enemy escort producing radar emissions and was not detected, until after torpedo impact. Submarines are,
as we know difficult targets to detect. Likely a operator on watch noticed BARB's small pip on their scope only after alerted by exploding
tanker vessels.


RADAR COUNTERMEASURES

APR-1 proved a effective tool on this patrol, often providing indication of bearing of a
aircraft contact, at times before SD even detected their range.

APR-1 detected ship based radar as well and proved vital to the success of this patrol.


SOUND CONDITIONS AND GEAR

Conditions

Sound conditions in area were overall excellent. Hydrophones could track enemy
precisely about 5000-7000 yards and distant noises could be heard at great distance.
These conditions no doubt assisted enemy in his effect depth charge attack.

Sound Gear

Sound gear functioned well overall in conjunction with the optimal conditions.


Enemy

Enemy sound gear appeared improved as were able to hear BARB at 4500+ yards
when running at just 95 RPM following Torpedo Attack No.4 and located her
with active sonar at 350 ft of depth, rigged for silent running.



RADIO

Radio function was optimal for most of patrol. Serious damage
to radio transmitter during depth charge attack did have lasting effects
in spite of our talented radioman's best efforts to repair completely.
Function was restored by not satisfactory for remainder of patrol.


No enemy radio transmissions or signals were detected on this patrol.




THERMAL LAYERS

One thermal layer was detected at 209 feet.


PERSONNEL

Crew performance was once again excellent on this patrol. Eleven men advanced in rating while
two officers and eight men earned qualification.


HEALTH AND HABITABILITY

Health and morale of the crew remained excellent throughout the patrol.
Meals were well prepared, certainly helping maintain these conditions along with
mostly calm, almost yachting seas and weather. Sinking of four enemy tankers
certainly kept morale high as well.

Only minor injuries such as bumps, bruises, and scrapes were suffered during depth charge attack.

Provisions 37 days

Reason for termination of patrol:

Fuel level. Time on station expired per orders.


REMARKS

A busy and challenging, but successful patrol, my final in command as will be relieved upon return to port.
Depriving the enemy of four large, valuable ,loaded, Northbound tankers and their precious fuel oil cargo was the proverbial "cherry on top" for this patrol. While it is regrettable were not able to expend last eight
torpedoes, it is understood the nature of operations as BARB was transiting another's area and accordingly followed orders.
BARB is a excellent boat, with a top notch crew that will no doubt have further success.

I've been getting comfortable with SH4 after being a long-time SH3 player, and I've been reading old patrol logs and the background history of the American sub campaign and decided to write a patrol log in the style of the "narrative" reports that were forwarded to command after a patrol was completed.

I left out a few sections which were standard in this style of log, namely miles steamed, days on station and the fire control data for each attack as I forgot to log these initially and didn't want to restart the patrol - I'll remember for next time.

There are likely a few minor errors but I hope it's an enjoyable read nonetheless. I'm just playing FOTRS without too many extras at this stage, it's a bit of fun getting creative with the photos and making it look like a typewriter-written report as it would have been in the 1940s.

Played at 98% realism, external camera off but left map contacts on while I still learn the ins and outs. I left the images full size for the best resolution, just zoom your browser out to 60-80% if the scrolling takes to long.

This career assumes USS Sawfish returned from the boat’s second war patrol earlier than the historical date of June 1943 and places it's return in May of that year, and that the historical skipper of Sawfish at this time, Lt. Cmdr E.T Sands, was transferred - therefore command of Sawfish is taken up by the fictional Lt. Cmdr J.P Salinger by June 1943 for the third war patrol.

Well done and welcome to the Pacific The photos in black and white and the report in the style it is, look great.

Not sure if you've discovered this site, but this is where I read he patrol reports (link below) . Great resource and interesting to read.

Look forward to the next report.

DESCRIPTION:

Small AK sailing in concert, unescorted, with another small AK rounding Cape Naka Shiretoko, Karafuto Island
about 15 nautical miles off shore, sailing into Patience Bay. After sinking lead AK in Attack No.5, target fired guns at BARB's scope and appeared to be charging for ramming,

REMARKS:

Explosion of ships ammunition cargo was truly awe inspiring. Due to short range, boat was shaken
and many thuds heard against BARB's hull, no doubt sounds of debris and shockwaves,
which continued even after vessel capsized.

A dramatic scene was observed via periscopes, when just as vessel was capsizing, a life raft, with one occupant deployed into the heavy swells, just seconds before it was too late.

BARB surfaced to recover this lone survivor for intel, but raft was empty when surfaced, apparently swept overhead into
the heavy seas when his raft was swamped.

GUN ACTIONS



USS BARB (SS220) GUN ACTION N0.1. WAR PATROL NO.8.

DATE: 1 June 1944 Time: 2346-2357
LAT. 47-51N LOG. 151-09E


DESCRIPTION:

Shimushu Type A Escort vessel, damaged by previous torpedo attack of
U.S.S. HERRING (SS-233) sometime on 1 June. Vessel was immobilized, possibly due to loss
of prop. Attempted to finish vessel off with torpedo but draft too shallow was vessel was not in ballast.
After nightfall, closed to 6000 yards and opened fire with Four Inch Fifty Caliber deck gun.
Sixty out of 150 rounds aboard were expended. Sixteen direct hits and eight near misses, left the vessel a
flaming wreck, bow to stern. Vessel sunk within one minute of ceasing fire. No survivors were observed.
Due to lack of return fire or visible acitiy it is believed all aboard were killed when third hit amidships, set off
a massive explosions. Round either struck unarmored fuel reserve or possibly ammo reserve.

Casualties: None.




(F) NAVIGATIONAL AIDES:

Spotted enemy lights and shore batteries on Cape Shiretoko, Karafuto Island.

Paramushiru and Taketomi Islands provided for excellent aides to navigation,
although no lights were spotted.

(F-1) HAZARDS TO NAVIGATION:

Several icebergs were spotted throughout the area.

1.47-48N 152-11E
2.53-0N 153-0E
3.51-0N 146-0E
4.51-40N 144-02E



(G) MINES:

No enemy mines were encountered on this patrol.

(H) THERMAL LAYERS:

Thermal layers were detected at 90 ft, 91, ft, 100ft, and 200 ft.
Majority of area did not feature thermal layers, a concentration of them
were found off Karafuto and Parmushiru Islands.


(I) ANTI-SUBMARINE COUNTER MEASURES AND EVASION:

Enemy ASW in area featured patrols by aircraft across the open ocean. Closer to the islands,
namely the harbors warship patrols were encountered. A impressive coordinated response occurred on 17 June
in response to the Chidori's reports of being torpedoed by BARB SSW of Paramushiru. Arrival of a DD
and DE, along with air support certainly prevented BARB from being able to close in for the coup
de grace.

Depth charge attack of 19 June was intense, accurate, albeit short lived. Considerable damage was done
by two skilled escorts. Impressive, large patterns were laid with variation in depth settings. Each escort took
in somewhat rapid succession. One tactic encountered was for one escort to run "up the spine" of BARB, while other crossed our bow,
with both laying impressive patterns to trap BARB one large shock wave. This tactic seemed to be used at least twice
and BARB suffered damage both times, including flooding. Once again, the Japanese escorts propensity I have read of in numerous reports,
to give up the attack early provided welcome relief.

Evasion was conducted by rigging for silent running, use of speed bursts at ahead full or flank for 25-30 seconds
once escort passes above to drop, frequent course and depth changes. When at 395 feet, a powerful pattern of charges
above BARB pushed her to 407 feet.



(J) MAJOR DEFECTS AND DAMAGE:

No major material defects.


Damage

BARB suffered serious damage during depth charge attack. All damage
was repaired at sea
over course of 72 hours unless otherwise noted.

Damage:

1. Flooding-Forward torpedo room. Busted valves and lines repaired. 2 ft
of water pumped out.
2. Flooding-Control Room. Busted valves and lines repaired. 1 ft water
pumped out.
3. WCA Sonar Stack in conning tower jarred lose, rendered inoperable rest
of patrol.
4. Forward Batteries
5. Compressor
6. Trim Pump
7. Rudder Transmission
8. No.1 Diesel
9. No.3 Diesel
10. JP Sonar Head-Deck Mounted
11. Radio Transmitter
12. SJ radar antenna.
13. Piping and water lines throughout boat.
14. High Pressure Air Lines in all compartments.
15. Light bulbs-all compartments.
16. Glass fixtures-all compartments.



(K) RADAR:

SJ

SJ performance was overall excellent.
Average target detection range was 22,000 yards.

SD

SD performance was adequate with typical
detection ranges at 18000 yards.


(L) SOUND CONDITIONS AND SOUND GEAR:

Sound conditions in the area were generally poor.
Sound gear function was limited to damage in depth charge attack.


(M) TIDAL INFORMATION:

Tides were typical for the area this time of year.


(N) RADIO:

Radio function was excellent until damaged in depth charge attack.
After repairs, function was hit or miss, so to speak.


(O) COORDINATED ATTACK GROUP OPERATIONS:

Attempt to coordinate attack proved difficult after initial
attack on convoy. One member of group (HERRING) made a attack while
BARB was jockeying for position on 31 May, damaging one AK and
crippling the convoys lone escort,
which BARB later sunk by gunfire. After this attack there was no further
communication from HERRING and no communication with GOLET was
never established in the assigned area.

(Real life note on the wolfpack: HERRING was sunk by shore batteries off
Matsuwa in the Kuril Islands
on 1 June 1944,vafter sinking the frigate Ishigaki and a merchant of the
convoy in question on 31 May.
BARB would go on to sink the other two. GOLET disappeared all together
without a word, any trace.
GOLET's CO, LCDR Clark had told LCDR Fluckey of BARB he would start his
patrol off South
Eastern Hokkaido. BARB would learn from a rescued Japanese merchant
seaman that there were mines laid
in that area. BARB attempted to warn GOLET, but never received a reply.
GOLET is believed to have struck a mine and sunk.
Another source says was sunk by Japanese escorts on June 14 1944 in sea
of Okhotsk.)


(P) PERSONNEL:


Crew performance was excellent on this patrol, as demonstrated
by sinking of six enemy merchant vessels, one warship, and severely damaging another warship.

As this is BARB's eight patrol, large crew turnover is anticipated during next refit period. Two new officers with no patrol experience, fresh from Submarine School reported aboard at Midway. New
"Old Hands" trained them well to takeover on next patrol.

One Officer and twelve men qualified on this patrol.
Eight men advanced in rating.


(Q) HEALTH AND HABITABILITY

Health and Habitability were overall excellent on this patrol.
Rough Arctic seas and temperatures made for difficulties at times,
but crew pulled together and overcame these challenges.

Food was well prepared and of high quality.

Minor injuries such as scrape, bumps, bruises were suffered as result of depth charge attack.


(R) MILES STEAMED-FUEL CONSUMED


Midway to Area
2300 miles 37564 gallons

In Area
7500 miles 102644 gallons

Area to Pearl Harbor
3632 miles 78555 gallons


(S) DURATION
DAYS

Midway to Area 10.5

In area 20

Days Submerged 2

Area to Pearl Harbor 11

Total 41.5 days



(T) FACTORS OF ENDURANCE


Torpedoes: 0

Fuel: 19244 gallons

Provisions 41 days

Crew Indefinite


Reason for termination of patrol:

All torpedoes expended.



(U) REMARKS:


With six merchant vessels and one warship sunk for estimated 28000 tons, with another warship severely damaged,
BARB's EIGHTH patrol, my first in command was a unabashed success. Crew, boat, and torpedo performance
were excellent. Commanding Officer does regret was unable to conduct more coordinated attacks
with group members. Commanding Officer takes responsibility for the miss of BARB's last four torpedoes due to
speed error. For that, a large merchant vessel managed to escape sure destruction. Noted for future patrols on how to avoid such incidents.

Patrol area.



Crew morale was listed as "broken" or "shaken" for many after a severe depth charge attack.



Bow of Chidori hit by torpedo. Night surface attack from 3000 yrds. Target slowed in heavy seas, causing torpedo aimed for middle of target to hit the bow. Vessel was badly damage, traveled slow but managed to escape thanks to dawn breaking early in the polar areas, foul weather setting in. Then clearing, arrival of two DE called in to help after dawn, as well as a patrolling aircraft preventing from closing target. (see report) .


Small AK sinking after single torpedo hit (blew up nicely)





DC splashes.



Empty raft after sinking of small merchant. Raft was launched just as vessel capsized. Initially had a lone crew member in it. By time BARB surfaced to close, the raft was empty. Heavy seas so assumed the survivor was washed out.



Lone survivor, soon washed out of raft.



Rendezvous with USS Herring in Sea of Okhotsk 31 May 1944 1000.
(Wolfpack operations)


PBY at Midway



Shaken crew (see cursor on morale)





Storms in sea of Okhotsk



Fired a "up the kilts" shot with AOB 180 but unfortunately the drift of the Chidori in heavy seas, torpedo ran down the port side.



Wolfpack message received on convoy. Entire three ship one escort convoy sunk.

AI sub (packmate) "Herring" damaged one AK (had a hole in side of it when I located it) and crippled the escort (props and rudders blown off, later located). BARB sunk all three AK and the escort. Escort sunk by gunfire after dark after torpedo run below, showing draft too shallow.

Default USS BARB SS-220 Ninth War Patrol screenshots

Few screenshots from 9th patrol. External Cams and contacts were off so not that many shots. Patrol Report to be posted soon. Do not recall if have ever had such a patrol playing without map contacts on. 11 ships with 78622 tons. Luzon Strait in August-September 1944 is certainly target rich environment, but difficult with large well defended convoys.

Default USS BARB SS-220 NINTH WAR PATROL 4 AUGUST-2 OCTOBER 1944

TMO Update V2.0
100 difficult, external camera and map contacts off.


I did my best to keep up with the data on this patrol but the action
in the Luzon Straits was busy. Attacks , esp the night surface actions and coordinated attacks required all of my attention, especially operating without map contacts to keep track on things, so my recording of data suffered at times.


Having said that, this was my best patrol ever without map contacts on. Six tankers, four merchants, one destroyer. One escort carrier damaged.

Fired 48 torpedoes (made a fast run to Saipan for reload after expending torpedoes early in patrol).


Wolfpack operations I have added to the upcoming V2.0 of TMO Update
were present in this patrol and worked well.

AI subs attacked convoys. Some placed in area along convoy routes were scripted attacks. Others set to spawn and patrolled area, responded to contact reports. I have found that they will respond to some degree same way carrier aircraft will respond if a friendly carrier or airbase is nearby when player sends contact report. I am unsure on distance will respond from but guessing at least 20 miles or less.

Anyways pretty cool when moving on on a convoy or after attack and see the flash explode from torpedo impact in the night sky. Enemy escorts are occupied making opportunities for attack.

US wolfpacks tended to "take turns" , typically three boats in a pack, attack from opposite sides. This tactic can player out pretty well in SH 4TMO now.

One coordinated attack I sunk three ships, pack mates sunk three, damaged another, which I later encountered and sunk. Anyways, new level of immersion in the sim, look forward to having it further implemented and refined in next release.

0938 Port flank escort departed station on "sweep",
BARB moved in for attack at high speed.

0940 Lead escort appeared to be Ukuru Class Escort Vessel.

0948 Convoy organized into three columns, three ships each.
Middle column has large AK leading two large AO.
Convoy spaced too tight to get inside for attack.
Brought stern tubes to bear to fire through first column
with MK 18 torpedoes (lack of wake advantage here)
at large AO estimated at 10000 tons in center of center column.

0951 Tubes 7,8,9 readied for firing.


0954 Fired tubes 7,8,9 at large Unidentified AO, similar to AKATSUKI MARU class 11800 tons.

BARB came under heavy deck gun, machine gun fire, with a few close splashesobserved. Star shells and searchlight from a AK illuminated BARB for a timeas opened range into the night at high speed. Lead and returning port escort began to chase BARB but never had a exact fix on her location.


0058 Both lead and port flank escorts observed heading for BARB at high speed.
Port escort, tentatively identified as a Type A Etorofu Escort, opened from about 3000 yards, but ceased fire after firing four rounds.


1008 Large AO sunk at 19-42N 119-00E

1011 Observed flash in distance and visible smoke fire.
Appears another submarine attacked convoy from starboard side
as all three of BARB's torpedoes fire hit her target and MK 18 would have
reached end of run by this time.

1012 Escorts gave up search for BARB, rushed toward other side of convoy. As convoy was now technically out of BARB's area and entered Area A2 in command area of COMSUBSOWESPAC, BARB turned North to disengage.
(This was not a planned/scripted attack in the campaign files. However, this area has several AI subs roving during this time period, as these waters had so many US subs the folk lore among Japanese sailors was "You can walk from Singapore to Tokyo on the periscopes of American submarines"

Convoy stumbled across where a AI was on patrol and/or the contact report sent earlier, drew a nearby sub, which does happen
if AI subs are close enough)

1035 Secured GQ.


1040 Unknown AK torpedoed by unknown submarine appeared to sink at 19-42N 119-00E. Observed sinking visually in dawn light, also disappeared from radar scope.

Only source of near continuous radar emissions was detected from middle
of the single column.

0450 Convoy appears to be several large AO's.
Perfect targets but BARB is out of torpedoes!
Will be forced to shadow convoy to try and bring in other
boats for attack.

0455 Flooded down to decks awash 26 ft.


0456 Contact in middle of convoy identified as a carrier!
CVE possibly Taiyo Class. The luck!
(This is a convoy of tankers with carrier Unyo I added to campaign to
represent a real life convoy BARB attacked in September 1944 in Luzon Straits while searching for Allied survivors in waters. BARB sunk a tanker and the escort carrier UNYO in real life. Of course I would be out of torpedoes when I run into this target lol)


0547 APR-1 detect radar signals/interference ahead.
Believed to be US submarine, possibly SEA LION.

Surfaced from decks awash.


0551 Lead and starboard escort (DE, SC) increased speed and charged towards BARB. Apparently BARB was detected.

TIME 0033 DATE August 31 1944 LAT. 21-4N LOG.119-44E

TARGET DATA-DAMAGE INFLICTED


DESCRIPTION

Large convoy eight AK, two AO, five escorts. Merchants in three columns about 1000 yards apart, 600-700 yards between ships. Due to moonlight unable to make surface approach and attack.
Escort screen and track shift away forced firing from longer range than desired. Torpedoes set to
low power. Selected large AO of around 10000 tons (Target No.1) in rear of center column.
Selected mid sized AO of 6000 tons (Target No.2) lead of starboard column. Timed shots
so torpedoes would pass astern of escorts. Fired three torpedoes at each AO from 6750/5540 yards.

SHIPS SUNK:
None

SHIPS DAMAGED

One mid sized AK. Estimated 4500 tons.


DAMAGE DETERMINED BY:

Observed 'flash' of explosion when torpedo hit target. This illuminated target long enough

REMARKS:

Torpedoes tracked properly and if had not been spotted due to phospohresence on a moonlit night,
would have hit targets aimed. Torpedo No.3 missed its intended target but found another in
outer port column. Both tankers fired at later identified and sunk in Attack No.2 and Attack No.4.
Identity of damaged AK was never ascertained.

DESCRIPTION

After sinking AO in Attack No.2, AK closed aboard fired on BARB's periscope, and attempted to
ram. BARB went to 100 feet. Upon return to periscope depth, the fires of the burning AK,
which was nearly submerged in water, just masts and stack poking aboce the surface, illuminated
a large AK which sailed to her strboard side. Conducted a quick set up and when
AK emerged clear of sinking tanker, fired three MK 18 torpedoes from tubes 7,8,9 at
range of 500 yards, with torpedoes set to 8 ft.

TARGET DATA-DAMAGE INFLICTED


DESCRIPTION:

Large Northbound convoy contacted on SJ radar. Convoy sailing in four columns spaced about 2000 yards apart,
with about 1000-1200 yards spacing between ships. Total pips counted in the "main body" were 14-16. A ring of
six or more pips on scope, presumed to be escorts surrounded the merchants. Initially attempted to shadow
convoy until night fall for coordinated night surface attack. However, after forced to dive to avoid SD
contact (convoys air cover), convoy zigged towards BARB while submerged deep. At periscope depth convoy was just six miles
to port and closing. With enemy coming to BARB, decided to attack. Submerged, BARB worked
inside convoy from the front starboard, avoided a Matsu Class DE (radar equipped) lead escort, and
crossed the outer starboard column. Lead AK in first center column was a smaller vessel, ignored it
as spotted AO SANRAKU MARU 3000 tons astern. Being northbound, tanker was
suspected to be carrying oil to Japan, indicated as well by riding lower in water.
Approached tanker and fired three MK 14-3A torpedoes at a range of 1511 yards.

REMARKS:

Fired three torpedoes on indviidual bearings aimed admidships, aft stack, and forward mast
As with most loaded tankers, more thank one torpedo proved somewhat redundant, as initial torpedo hit
is typically enough to ignite volatile fuel/oil cargo aboard, resulting in a destructive explosion.
However, a spread was fired to account for being detected given daylight and clear conditions or attack
or torpedo malfunction.

Convoy attacked was quite large and well protected by Japanese standards. Reports ofa increase
in enemy convoy size, composition, and protection, including multiple escorts and air cover have become
normal as of late. Formation spacing made attack more than one target at a time difficult. Enemy escorts and
air cover were first team and proved a challenge. One exception, is a apparent failure by enemy air cover to report
having bombed BARB or miscommunication, that led to convoy zigging toward BARB, setting up convoy for submerged
attack.

TARGET DATA-DAMAGE INFLICTED


DESCRIPTION:

Destroyer and two other escorts began pursuing BARB on the surface. With engines on
overload, BARB was able to outpace two subchser type escorts, but naturally, the DD, guided by his radar,
closed at a high rate of speed estimated 30+ knots and was overtaking BARB. Decided to utilize the
wakeless electric fish loaded in stern tubes for "down the throat" shot.. Almost as if the DD's Captain
sensed this, she began to zig back and forth along her track, at 25 knots estimated, as she was still closing the range.
A quick estimation of the timing garnered a solution with a chance to work. Fired two MK 18-2 torpedoes
from tubes 7,8, at a range of 3100 yards. Fired tube MK 18-2 from tube 10 at 2900 yards.

REMARKS:

Fired torpedo hit, although intended to be fatal, served as a "marker"
which assisted the fire control party. Quite surprised after the first hit, DD continued its pursuit of BARB.
There was a 120 second interval before the fatal torpedo was fired from the first two.
DD was making his zigg to port and sailed right into the well timed fish. MK 18 fish, with their lack of wake
are preferred for placement in stern tubes for just this sort of situation.

abroad.Came under heavy deck gun and machine gun fire vessels in outer column. BARB was
briefly illuminated by spotlight and star shell. Gunfire was not accurate but a few close splashes.
BARB was illuminated for a time by star shells and searchlights. Escorts (lead and port) chased BARB and fired upon, but never located exact position.

REMARKS:

Fired torpedoes on divergent spread with points of aim amidships, forward mast,
and stack aft. All three torpedoes hit, igniting a massive, devastating, explosion and fireball
expected from a fully loaded tanker. Second torpedo hit seemed to set things off.
Third torpedo hit aft under stack, set off another massive explosion,
likely blowing out her boilers/engines. Tanker took a down angle by stern with fires ranging.

With BARB just 1500 yards away and on the surface, the sounds and sights really set in for BARB, especially those topside. BARB came under heavy, but inaccurate gunfire from nearby vessels.

REMARKS:

Due to possible speed error, first two torpedoes missed slightly astern, but third torpedo,
aimed a forward mast, hit the stern of the AK. Out of torpedoes, with star shells illuminating area,
under machine gun fire from the AK, BARB had to turn away and depart area.


Observed the AK was damaged, slowed and the went dead in the water. Obviously propulsion/steering damaged
by the torpedo hit to the stern. Rest of convoy moved on, but one AK remained in area.
BARB hung out in area to wait out the escort, so could finish off the AK with deck gun if possible.

Enemy ASW activity in the Luzon Straits area was intense and primarily consisted of day and night
radar equipped air patrols. Many flew low making timely detected by SD radar difficult. As a result, several
were detected at just 5-6 miles and BARB was subseuqently bombed several times. A new tactic
by enemy air patrols appears to be to fly low at high speeds, which makes early detection via SD radar
difficult as it reduces detection range. Enemy appears to keep radar off at times and turn on
as needed based on APR-1 readings.

Surface patrols consisting of DD/DE were encountered and avoided. One responded at a attack on a convoy
and was inbound to assist a crippled vessel damaged by torpedo and finished off later with gunfire.

A midget submarine was encountered in the Balingtang Channel off Babuyan Island. Given their limited range and thus
need to operate from nearby base, highly likely this boat was patrolling the channel for our submarines. BARB was submerged
when spotted the sub and out of torpedoes, so had to evade.
Enemy convoys transiting area often had air cover and one convoy encountered had a escort carrier
in the convoy.


All enemy convoys encountered had at least four escorts, sometimes as many as seven or eight.
These vessels were typically purpose built escort vessels "Kaiboikan", some eve DD and DE type escorts.
Typically, at least one escort in convoy was radar equipped. A radar equipped DD (Fubuki Class)
detected BARB on surface at about 6000 yards and pursued. BARB sunk this DD with a "down the throat" shot from
stern tubes. (Torpedo Attack No. 10).


Depth charge attacks were intense and accurate on this patrol. Enemy has expanded his ASW capabilities
with improved, powerful depth charges and sound/sonar equipment. BARB, out of torpedoes, but working inside
convoy to come up to depth and broadcast radio report, was detected as she ascended from 350 ft and passed 150 feet by
a escort some estimated 4000 yards away. With multiple escorts in convoys, usually at least two remain in area to attack, sometimes more, employing
apparent team tactics. Often conducted attacks in rapid succession.


Evasion of enemy ASW consisted of diving to avoid aircraft. Often times it was found
the APR-1 Radar Warning Receiver detected a aircraft's radar emissions prior to SD contact,
Several dives were initiated due to APR-1 signals prior to contact.

Submerged evasion of attack consisted of silent running, consistent course, and depth changes,
combined with "sprred bursts" of 30-45 seconds during and imemdiately after depth chrge explosions.


BARB's ideal evasion depth has been found to be 390-395 ft. One strong pattern did push BARB from 385 ft to
412 ft. BARB is a well built boat and the 112 ft past test depth seemed to do her no harm.




(I) MAJOR DEFECTS AND DAMAGE:


No major material defects occurred on this patrol.



*Most damage was repaired at sea. However, serious damage to Hydraulic pumps,

**Bow and Stern dive plane transmissions rendered BARB somewhat sluggish for remainder of the patrol,
especially when submerged, in spite of repairs.

All damage listed was repaired at sea unless otherwise noted.

1. Hydraulic Pumps-Seriously damaged.
2. Bow Dive Plane Transmission**
3. Stern Dive Plane Transmission**
4. Flooding-Aft Engines Room-Sea valves busted. 2 ft water incompartment and flooded bilges.
5. Flooding Aft Torpedo Room-Leaks from aft tubes. 1 ft water in compartment.
6. Trim Pump
7. Forward Batteries
8. Compressor
9. Torpedo Tube No.10
10.Torpedo Tube No.7
11.JP sound gear
12.Various pipes- Leaks in all compartments. Serious leak in conning tower.
13.High Pressure Air lines-Leaks in compartments.
14.Light bulbs-All compartments
15. Glass fixtures-All compartments.




(J) RADIO:

Radio function, especially key on this patrol due to group operations
was excellent. Messages sent and received with little to no trouble.



(K) SOUND CONDITIONS AND SOUND GEAR:


Sound conditions were overall excellent in the patrol area.

Sound gear functioned well until damaged by depth charge attack. JP listening gear was not at optimal performance for remainder of patrol.


(L) RADAR:


SJ

SJ-1 radar performance was excellent on this patrol.
Typical detection range was 24,000 yards. PPI scope once again proved itself a major
tactical advantage for BARB.


SD

SJ radar performance was somewhat inadequate on this patrol.
A apparently new enemy tactic appears to be to fly low at high speed, which made early detection
difficult at times. Typical detection range was 11000 yards or less.

APR-1 often detected radar emissions from aircraft prior to SD contact, providing some early warning.



Enemy Radar

Nearly all enemy aircraft in area were found to be equipped with radar.
Based on encounters it is believed enemy air mounted surface search radar
has a range of of about 15000-20000 yards. Daytime aircraft tend to make sweeps
with radar intermittently and focus on a target at close range, perhaps to counter our radar
warning equipment. Night fliers tend to keep their radars active at all times.

Enemy ship based surface search radar was encountered on at least once vessel in each convoy.
Against a surface submarine the enemy raar appears at times ineffective. However,
BARB was detected at least one from 6000 yards by a destroyer, prior to attack.



(M) THERMAL LAYERS:

Two thermal layers were recorded on this patrol.

1. DATE 1944/08/31
TIME 0044
DEPTH-216 ft
LAT.21-4N
LOG.119-44E

2. DATE 1944/09/15
TIME 1450
DEPTH 130 ft
LAT. 20-47N
LOG. 120-05E





(N) RADAR COUNTERMEASURES:

No known radar countermeasures wer encountered.
While it is not believed typical enemy vessels or aircraft
encountered can detect radar emissions, BARB
exercises caution by keeping SJ radar off for majority of time,
with sweeps every 15 minutes during standard patrol.
Sweeps may be somewhat longer when in contact with/tracking a enemy.



(O) GROUP OPERATIONS:

For this patrol, BARB was assigned to Task Group 17.5 (TG 17.5), a coordinated attack group, or "Wolfpack", with QUEENFISH and TUNNY under the command of CAPT E.R. Swinburne, USN., embarked aboard BARB.
Group was nicknamed "ED's ERADICATORS" after our Commodore. Assigned to the Luzon Straits area, pack operations proved effective and costly for the Japanese. Another Wolfpack, under CDR T.B. Oakley, CO of GROWLER,
"BEN's BUSTERS" operated in area the West . The BUSTERS consisted of GROWLER, PAMPANITO, and SEA LION.


Further underway training was conducted en route to Midway from Pearl Harbor. Upon departure from Pearl Harbor,
group formed a scouting line fifteen miles apart with BARB in the center, TUNNY to port and QUEENFISH to starboard.
This line was maintained the entire journey from Midway until reached the Bashi Channel to enter assigned area
in Luzon Straits. Each boat proceeded independently into assigned area throughout the strait on surface at night.
BARB, QUEENFISH, and SEA LION each patrolled their own designated sector of the assigned area.

After several days of empty seas, contact was made with a convoy on August 30 and coordinated attacks
throughout night and early morning of 31 August savaged the convoy. BARB sunk three of her ships, two, possibly three
were sunk by her packmates.

Follow up attacks on September 1 left more vessels sunk. Contact was lost with TUNNY after 1 September,
as she had apparently been seriously damaged by aircraft bombs and departed area.

BARB expended last of her initial torpedo load and proceeded to SAIPAN to reload torpedoes.


Activity in the straits was somewhat absent during BARB's trip but upon return shifted into overdrive.
While en route to join the BUSTER's for a coordinated attack, BARB encountered a large convoy and attacked,
sinking a tanker.

Night of 11/12 September, convoy was attacked by BARB, GROWLER, SEA LION, QUEENFISH, and later
,PAMAPNITO, at least five ships were sunk and others damaged. Unknown to all at the time,
Allied POW's, mainly British and Australians held captive since Fall of Singapore in early 1942, were aboard as were
being transported to Japan. PAMPANITO first discovered these poor souls and reported in. BARB and QUEENFISH
were directed to the area to assist in the search, locating five men in the water, four Australians and two Brits.

On the 16th, BARB was out of torpedoes, but encountered a convoy with tankers and a escort carrier
Shadowing the convoy, her contact report brought in QUEENFISH, which attacked and sunk a tanker, confirmed.
Although out of torpedoes, BARB opened fire on carrier from 5000 yards with 4 inch deck gun. This was meant
as more of a diversionary tactic, and it worked. After scoring a hit, which blew aircraft off her deck and set her afire,enemy escorts backed off depth charging the QUEENFISH and raced towards BARB, with promptly withdrew.

Overall, coordinated group attacks worked well, especially in this area, where large, well defended convoys are the normal.
Chaos caused among a enemy convoy by coordinated attack served the group well in evasion.

Group sunk a total of seventeen ships. BARB (11), QUEENFISH (4), TUNNY (2).
BARB also damaged a CVE by gunfire. QUEENFISH damaged at least two other ships, TUNNY damaged at least one.




(P) PERSONNEL:


Crew performance was excellent throughout this patrol. This is best attested to by eleven ships
sunk in total, with one carrier damaged. One Officer and twelve men qualified on this patrol and four
advanced in rating.



(Q) HEALTH AND HABITABILITY


Health of the crew and habitability of the boat were overall excellent on the patrol.
Extra crew (two officers, plus survivors rescued from water later in patrol) were accommodated with little to no issue. Food was overall excellent and always well prepared, even with somewhat extended duration of the patrol. A "pit stop" at Saipan half way through patrol of course assisted with these matters.


(R) MILES STEAMED-FUEL CONSUMED

(T) FACTORS IN ENDURANCE:


Torpedoes: 0

Fuel: 23566 gallons

Provisions: 34 days

Crew: Indefinite

Reason for termination of patrol: All torpedoes expended, survivors aboard
in need of medical care.




(U) REMARKS


Busy, long, challenging, but ultimately rewarding war patrol. BARB sunk six tankers, four merchants, one destroyer, and
damaged a escort carrier by gunfire in fifteen torpedo and three gun attcks.
Total estimated tonnage sunk is 78677 tons.

Sheer volume of enemy traffic throughout area provided for a pace of operations not typical of other patrol areas.
Luzon Strait as one would assume, if a vital choke point for enemy shipping. Multiple large, well defended convoys, pass through
a area well patrolled by enemy aircraft and surface vessels.

Aside from of sinking enemy vessels, BARB rescued six POW's from the sea, inadvertently put there
torpedoes of our subs, when ships they were aboard, bound for Japan, were sunk on 11/12/ September.
This was BARB's Ninth War Patrol, and my second in command.

Default TMO "Evil Aircraft" sunk the BARB.

USS BARB SS-220, was lost on 18 November 1944 at 32-09N 127-36E in Area 9, in the East China Sea, just south of Tsushima Strait.

BARB, chased a convoy all night, after multiple attempts, was unable to attack on surface due to vigilant, radar equipped escorts. Tried for a dawn approach submerged , but was spotted by a PETE floatplane which spotted BARB at periscope depth, alerting escorts.

Escorts located BARB in the waters with 315 max depth waters and after a depth charging lasting from dawn until noon 18 November, BARB had escaped and was cruising at 300 feet, just off the bottom of the sea, when began rise to periscope depth at 1900 for a visual check , after hours of no contact with enemy.

As BARB passed 125 feet on way to periscope depth, heard a brief noise(presumed to be the low flying aircraft), and then two depth charge explosions which severely shook the boat. Followed four seconds later by even more intense explosions. Lights went out for five seconds, flooding reported in stern, damage reports rolled in, along with calls for medic.

I had external cam on this patrol, so went outside after first explosion.
One aerial depth charge had landed to port, could see the explosion bubble dissipating, while the second depth charge landed to starboard and exploded just as I got to external view. So two aerial depth charges bracketed BARB's stern about around the point where stern torpedo room bulkhead to maneuvering room would be on a GATO sub, very close. Perhaps 20 feet, within kill range for depth charges typically. Then I saw the aerial bombs dropped, one of which scored a direct hit on the stern. Yep, the lucky, bomb contacted the stern around the stern torpedo room loading hatch.
(I tried to screenshot, hit the keys but apparently not fast enough as this happened quite fast)

BARB's stern had taken two close depth charges, and a few seconds later, a DIRECT bomb hit seconds later from a EMILY flying boat, which likely detected BARB with MAD (TMO planes have a sensor simulating MAD in late war). and was lined up for attack as we , not aware of the plane, began rising to periscope depth.

Stern was destroyed, wrecked. Large hole blow in it, with port prop shaft and stern torpedo bulkhead destroyed, nearly all equipment smashed and sadly, all but one crewman killed in the stern torpedo room, with one severely injured (health was 20/100. Flooding also in engine rooms , bulkhead 90 percent damaged with all suffering severe injuries in compartment. Hull damage was at 80 percent. Boat lingered a few moments, stern torpedo and engine rooms rapidly flooded, BARB took a down angle by stern and paused at 88 feet, stopping her ascent, began rapidly going down in spite of ahead flank speed.. Blew ballast tanks to get to surface to save the crew but did not rise in time as flooded out compartments stern dragged her down . Boat, in 300 ft waters with angle caught its self and bow was about to break the surface while what was left aft touched bottom. Just then, EMILY made another attack at BARB was at 94 ft, dropping a depth charge above, but not terribly close, yet close enough to shake the boat. Bow slid beneath surface, stern crashed into bottom. Hull collapsed, went to 100 percent. All was lost.

Oddly enough, the boats external model then just disappeared lol but could stay inside, no controls worked, but game did not end. I had to exit. Side effects of altering the damage model is sometimes SH 4 does not play out the "fade to black" sequence . Can also have to do with the bottom. I've been depth charged, pounded into the sea floor before, where sub disappears lol and external model is gone and im dead, but dont get the death fade to black sequence.

Definitely a lucky hit for the plane. This was first time I've been sunk or even severely damaged by aircraft in years lol. Disappointing. really had a great campaign going with the BARB and this patrol was a exciting and successful one already with just eight torpedoes left aft (All but three fired forward, all bow tubes disabled in November 15 depth charge, could not repair at sea)

Survived these depth charge attacks, being fired at, and chased on surfaced, but taken out by a flying boat. Ahhh. Reminded me of how TMO aircraft earned their reputation for being "evil".


BARB, during her 10th patrol, which she was on at time of loss, sunk the following vessels:


AO CHIYODA MARU 5004 tons 8 November

AK JOKUJA MARU 7200 tons 8 November

Aikoku Maru Class Auxiliary Cruiser 14500 tons 10 November


CVE Akitsu Escort Carrier 11800 tons. 15 November




Ah, well to start a new campaign.


Screen shots:

AKITSU exploding a few minutes after taking 3 MK 18 torpedo hits.



Akitsu listing to port



First view of Akitsu through observation periscope.

Akitsu on fire listing. Took about 15 minutes to sink.



Akitsu listing



First MK 18 torpedo impact



Second MK 18 torpedo impact



DC pattern on 15 November following sinkng of Akitsu. From a Type C escort.
Believe this was pattern which damage forward torpedo compartment. Caused some flooding , disabled forward dive planes transmission and tubes 1-6. All six bow tubes could not be repaired at sea.


EMILY which sunk the BARB, flying away after initial drop that scored the fatal hits.



Last DC explosion, following follow up drop by the EMILY H8k flying boat.
Unfortunately, the halo effect did not show up on this one as it does usually.
