USS BARB SS-220 31 May 1944-Wolfpack action, Entire convoy sunk.
 

TMO Update V2.0
100 difficulty
Camera and Contacts on for this patrol.

Note: This is V2.0 of the update mod, which is final stages of testing. Certain patrol objectives do involve wolfpack operations, within the bounds of the sim of course. Some orders will require rendezvous with other subs, dispatch to certain area for coordinated attacks. Due to navigation errors I did not arrive in time to attack with the AI sub standing in for Herring after meeting up with them earlier in day on May 31, but found a couple hours after. One merchant was damaged and convoy had passed through the designated ambush area. Later after my own attacks, the convoys lone escort was dead in water with props and rudder blown off, about 7000 yards astern of the last ship. No other allied forces in area, thinking AI sub got some torpedo hits in.
Also testing out my new longer sinking times in V2.0, working great thus far.


This mission was created and added to campaign for testing in order to replicate Barb's real life Eighth War Patrol (first under Eugene B. Fluckey, her famous skipper) in the Sea of Okhotsk . Used several resources including Admiral Fluckey's excellent memoir "Thunder Below!" , BARB's actual patrol reports, and other resources. These patrols will be in V2.0 as single patrols in addition to the career but modified for career to work with any boat, not just the BARB.(Would be weird to be in the Silversides in a career and get referred to on radio as Barb lol, immersion killer).

War Patrol Day 2
 

10 Dec 1941 01:08
War patrol Day 2.
We have received another signal from COMSUBPAC: JAPANESE FORCES APPROACHING APPARI (sic) LUZON X INVASION IMMINENT X
We can’t get there to oppose the invasion, but perhaps we can interfere with their logistics.

04:14
We have received yet another signal from COMSUBPAC: ENEMY INVASION FORCES HAVE BEEN REPORTED OFF THE COAST OF VIGAN WESTERN LUZON X INVASION IMMINENT X
The Japs are certainly busy! Vigan is a lot closer to us, only some 160 NM from our current location. We could be there in under 15 hours, so I’ve ordered ahead full and changed course to 358°. My NO has plotted a new course to place us off the invasion beaches. Our current position is 15°11’N, 119°37’E.

12:00
We are making good progress, currently at 16°34’ N, 119°42’ E, course now 024°, less than 20 NM NW of Santiago Island at the mouth of Lingayan Gulf. I have ordered a dive to 100 ft, ahead two thirds. Lingayan Gulf is an ideal place for an invasion - the lowlands from there lead right towards Manila. I want my sonarman to spend some time searching for possible contacts, before we proceed towards Vigan.

13:00
We have heard no sound contacts of note. I have ordered us to periscope depth.

13:05
A periscope sweep and another hydrophone sweep reveal no contacts in our vicinity. I have ordered us to surface, ahead full.

13:25
It’s said that best laid plans don’t survive first contact with the enemy. At 16°41’ N, 119°44’ E lookouts spotted multiple aircraft coming from aft. I quickly counted 20(!) twin-engined bombers in echelon formation on a direct intercept course. As I ordered a crash dive at flank speed, with a hard turn to starboard, they started to strafe and bomb us from medium to high altitude. Bomb detonations were so frequent and close together, we could not count them. As I write this, additional detonations are audible, so at least some aircraft must be circling and dropping ordnance in a vainglorious hope of a lucky hit on us. Fortunately, reports from all compartments indicate no damage, and no injuries apart from bumps and bruises suffered by those caught unawares by the crash dive.

13:32
More detonations in the distance; why are they continuing a futile expenditure of ordnance on a target they cannot see?
We are currently on a heading of 098°, ahead two thirds, at a depth of 150 ft. Battery is already down to 87%, so I’ll reduce speed before long to conserve power.
The enemy knows we’re here now, so we’ll remain submerged until nightfall.

13:52
I have ordered a reduction in speed to ahead one third, with battery reserves reduced to 85%. I have also ordered a return to our plotted course. We haven’t heard any more bomb detonations since before 13:40, so it looks like they’ve finally given up.

[NOTE: I went back to check this encounter on replay. There were, indeed, 20 twin-engined bombers that all either bombed or strafed us. It was an impressive number of bombs that were dropped! The bombers were followed by a number of waves of fighters, which attacked the same location we had vacated over the next 10 to 15 minutes. I counted 50 fighters in total! The bomber "formation" was especially ridiculous - maybe not the number of aircraft, but certainly the formation. They should have been in tactical groups of three, not a 20-aircraft echelon! And 50 fighters turning up in such a short space of time? Are these known bugs?] :k_confused:

16:00
A hydrophone sweep shows no contacts. But they’re bound to be looking for us. And expecting us!

17:00
Still negative on another hydrophone sweep.

17:11
The Nautical Almanac says the sun should be setting, so I’ve ordered ahead two thirds and periscope depth. Time for a look see!

17:26
Periscope shows all clear. But it’s still too bright for comfort -- I don’t want to get caught out by a lucky sighting by an enemy aircraft. So I’ll check again at 18:00.

17:53
Hydrophone and periscope sweeps show all clear. We surface at 18:00. Battery reserves are now 75%.

18:10
We surfaced at 18:00 at 16°50’N, 119°50’E, ahead full.
We received a signal from COMSUBPAC. Grim news, indeed: BRITISH BB PRINCE OF WALES BC HMS REPULSE SUNK BY JAPANESE BOMBERS OFF MALAY PENINSULA X GUAM CAPTURED X JAP FORCES HAVE LANDED AT APARRI AND VIGAN PHILIPPINES X
The British have one of the best navies in the world. The IJN was modelled on it at one point! But air power is showing the day of the battleship may be over. And we very nearly joined those two grand vessels on the bottom of the sea today, too!
At our current speed and course we should arrive off Vigan in less than five hours. Perhaps under cover of darkness we can demonstrate that our submarines pose just as great a threat to Japanese shipping!

21:05
We are at 17°19’ N, 120°02’ E, inside 20 NM from our plotted arrival point off Vigan. At 21:00 I ordered a dive to periscope depth to make a hydrophone sweep, to see if we can pick up any contacts. We’ll proceed from here with more caution.
Third watch is on duty; first watch sleeping -- I want them well rested for the night ahead!
I must commend my crew. Morale is good; all remained calm through their first combat experience today; and even though we didn’t have time to go to battle stations, all operated magnificently to get us under in good time to avoid the worst of the onslaught of multiple bombs dropped all around us. That experience I’m sure will stand us in good stead in the future.

20:20
The hydrophone and periscope show all clear, so we are surfacing, ahead standard.

22:05
I conducted a binocular sweep ahead at 22:00. No visual contacts. We are now about 10 NM from our plotted point of arrival, so I ordered periscope depth for another hydrophone sweep.

22:06
And there there are! Multiple sound contacts ahead at long range, both warships and merchants. Right where I expected them to be!

22:15
The warships seem to be concentrated ahead, near the plotted point of our arrival. The merchants seem to be further inshore. I’m altering course towards shore, course 070°, and what I hope will be a target rich environment!

22:18
With a clear periscope sweep, I’ve ordered us back to the surface, ahead standard, for our run in towards the coast. The lookouts will have to be extra wary of the warship threat to our north,

22:50
The Moon has risen, and the weather remains clear and calm. This should aid us greatly in setting up any opportunities to attack the enemy. Equally, it gives the enemy a better chance to spot us in our approach on the surface. So, I shall dive again at 23:00 to conduct a hydrophone sweep.

23:10
I ordered a dive to periscope depth at 23:00, and commenced a hydrophone sweep shortly thereafter. This shows a group of warships and merchants between bearings 263 and 281, with the warships further offshore than the merchants. On those bearings they would be 10 to 15 NM offshore -- there appears to be nothing closer in, where I was aiming for. Are they withdrawing? Have they completed their landing operations? We shall monitor the situation for the next while before deciding what to do.

[NOTE: I took a toilet break here, leaving the sim running in real time, and guess what happened?!] :doh:

23:47
We have lost all hydrophone contact. I am surfacing to pursue northwards in hope of reestablishing contact.

23:52
Periscope showed all clear. I ordered us to the surface at 23:50, ahead full, on new course 359°.

Really enjoy your reports "as it happens.":Kaleun_Salute:


Far as the bombers. December 10 with those numbers, sounds like you ran into the bombers heading for Cavite, for the big air strike on December 10 or other air strikes at locations on Luzon etc. Fighters would be their escorts. Unfortunately, not way to really put them in realistic formation. I tried to make them spawn in somewhat accurate formation but does not always work out. Depending on the direction they were traveling, they could have been returning from a strike and had some bombs on board(planes do not always drop all ordnance for some reason) so may have been returning. They do not level bomb , so after attacking, they reform in odd formations as well.

Unfortunately, since planes in the game were added from development to be ASW, if they see you, the player's sub, they will forgo any other mission and focus on you. That is something that can not be changed without altering the coding. So the air strike spotted you and see lets get the sub! lol

Also, when you are detected a "warning" is broadcast to other forces in area, so if they are within range they will come looking for you. Aircraft(obviously) can get there in most timely manner. In stock and default TMO the time was 15 minutes which I find absurdly low, because is a patrol was 16 minutes away, would not come looking for you.. I set it to 24 hours. Now, that does not mean everything within 24 hours travel will come your way, there are other factors at play, but it does mean will attract attention. .

They continued bombing the site because was last place they saw you. If they got lucky and spotted your elsewhere submerged, would focus on you. False contacts happened/happens in ASW. Same reason after surface attack once lose sight of player sub, often assume you submerged and will circle than start depth charging a random spot where have false contact. Poor whales/fish lol

Yes the amount of ordnance they dumped was impressive I am sure lol.


Finally, interesting you mentioned all the messages. I added a lot of them. Very tedious work lol. V2.0 will have refined messages and they will be theater appropriate so if operating out of Manila, will not be taking orders from COMSUBPAC and vice versa.

Regarding Repulse and Prince of Wales. They are operating in their historical time and place in current version and are attacked by bombers. In V2.0 with pre war career start, player may be assigned to a pre war patrol to the area and orders to operate with them in opposing invasion in area. If around them at appropriate time and place, can witness the air strikes that sink them. Pretty impressive to watch. The numbers overwhelm them and usually sink them, but sometimes they survive, listing, on fire. A Betty torpedo bomber (unfortunately we dont have G3M NELL bombers in SH 4) dropped a fish and caught fire from AA, then crashed into Repulse at the waterline.



Last test, Repulse went down quickly. Prince of Wales lingered for 14 hours, then exploded (fire mod which causes damage at work) in massive fireball, rolled over and sunk.

War Patrol Day 3
 

11 Dec 1941 00:10
War Patrol Day 3.
I ordered a dive to periscope depth at 01:00 to conduct a hydrophone sweep, at 17°42’ N, 120°13’ E. This proved negative. Upon surfacing, I will change course to NW.

02:10
I again ordered a dive to periscope depth at 02:00 for a hydrophone sweep. Negative again. Upon surfacing, I’ll continue to NW until the next check.

03:10
17°56’ N, 119°59’E. Ordered periscope depth at 03:05 for another hydrophone sweep. Still negative. If they are retiring, are they heading north towards Formosa, or west towards Hainan? Either way, they should still have been within hydrophone range. Just how fast are their transports?

03:20
I ordered the boat to surface at 03:16, ahead full, returning to course. If our next hydrophone check is negative, I shall continue into the Luzon Strait, making best speed on the surface. We shall dive at dawn, conserving batteries to the maximum. My aim will be to loiter to the north of the Babuyan Islands in the hope of interdicting any shipping crossing from Formosa to the invasion beaches and back.

04:15
I ordered periscope depth at 04:10. Hydrophone again shows no contacts. It certainly looks like we’ve lost an entire convoy! When we surface, I shall pursue the Luzon Strait option.

05:10
18°15’ N, 119°59’ E. Dawn is approaching, and we have changed course to 037°. I anticipate a significant enemy aerial presence by day, so I will be ordering us under before the sky gets much brighter.

05:45
I ordered a dive to 150 ft at 05:35, a little after sunrise, at 18°19’ N, 120°01’ E, ahead one third once we reached our depth. An immediate hydrophone sweep revealed no contacts.

16:24
It is just after sunset on the surface, so I have ordered periscope depth. No sound contacts all day long.

16:49
Hydrophone and periscope sweeps show all clear. We surface at 17:00. Battery reserves are good at 71%.

17:05
We surfaced at 17:00, ahead standard, course 037°.

18:05
We have received a signal from COMSUBPAC: We are now at war with Germany and Italy, as well as Japan. So now we are in a two-ocean war! Good news is that the marines on Wake Island have defeated a Japanese invasion attempt! That raised a hearty cheer from my crew when I read it to them over the intercom.

20:00
I have ordered a dive to periscope depth to conduct a hydrophone sweep, at ahead one third. I have a standing order for this every three hours. I’ll be able to grab some much needed shut eye in between dives.

20:15
The hydrophone search proved negative, so we are back on the surface, ahead standard, still on course 037°. Our next dive will be at 23:00.

23:00
19°21’ N, 120°47’ E. The Moon has just risen, and I have ordered our next dive for a hydrophone sweep. Ahead one third once we are at depth.

23:15
Hydrophone sweep was again clear. We have surfaced, ahead standard, maintaining the same course. In about three hours we will change course onto the first leg of our patrol in Luzon Strait.

War Patrol Day 4
 

12 Dec 1941 00:10
War Patrol Day 4.
Weather remains clear and calm. Conditions are very pleasant up on the bridge, with a gentle breeze out of the north. We are sailing almost directly towards the end of the handle of the Big Dipper - long before I learned stellar navigation at the Naval Academy, my father taught me to recognise the constellations. But there’s no time for stargazing for those on watch.

01:35
19°38’ N, 121°00’ E.
We have turned to our new course, 076°. We dive again in less than half-an-hour.

02:20
We dived to periscope depth at 02:00. Again a clean sweep - no hydrophone contacts. I ordered us back to the surface at 02:15.

03:00
I ordered a reduction in speed to ahead two-thirds, to conserve fuel. We’re close to base, so fuel supply shouldn’t be a problem, if all goes well. But who knows what will happen in the coming days and weeks if the Japanese forces ashore are not stopped. We must remember that their army and navy have over four years of combat experience in China -- no matter what politicians back home might say about them!

04:40
With the sky brightening, lookouts spotted a Japanese destroyer at long range, bearing 315, at 04:34. I ordered a crash dive to 150 ft and crew to battle stations. Hydrophone quickly picked up a second warship contact. It appears they did not spot us - they are continuing on their course of about 135° at high speed.

04:52
I have ordered us to periscope depth and new course 180°. The warships began to manoeuvre soon after crossing our bow.

04:59
Active sonar!

05:01
I have ordered us to 200 ft. We are on silent running. Passing through a thermal layer. Active sonar has stopped, and started again.

05:04
Several depth charges. Manoeuvred into the attack to attempt to evade. Aft dive planes transmission is damaged. Damage control team is on it.

05:08
Active sonar from two vessels. Close! Evading!

05:12
Multiple depth charges; multiple systems damaged! But no flooding.

05:15
Sonar is off line, so we’re deaf to what the enemy is doing! But the aft dive transmission is repaired.

05:16
Active sonar!

05:18
Multiple systems damaged from close depth charging. Some flooding in engine room and forward torpedo room.

05:23
I have ordered a new depth of 240 ft. Hopefully this will reduce the severity of the battering we are taking from depth charges …

#####

Okay, this was a brutally short war patrol! When I ordered the final dive to 240 ft, the boat just kept on going -- both dive plane transmissions were damaged! Blowing ballast helped for only so long. Not much I could do.

This is the second time I've been detected (passively?) by enemy destroyers that seemed to be far enough away not to have picked us up, or where we were far enough aft to be out of their hydrophone arc. But, no, they zeroed in on us like a laser. They must have exceptional hearing! lol

Ouch lol.

They most likely heard you dive the boat. All Boats are very noisy when diving/surfacing. Your engine speed was mostly likely high, esp if at crash dive, dive, once you hit the depth the game considers you submerged...in fleetboats its 40 feet, probably less for S boat then you are making a lot of noise under water they can hear, even some distance away. Plus the sub's sound signature, without RPM's, with pumps, tanks blowing etc is making louder during the dive/surface sequence. Sounds like they heard you dive, were into "alert" mode and came hunting. Located you with active sonar, possibly heard you, then located with active.

S boat's are in general quite noisy , esp compared to the modern boats, easier for AI to detect. I dealt with this in my recent Narwhal career. Old boat was noisy as hell and of course could not dive very deep, like a S boat.

Another factor is enemy destroyers/asw type vessels assigned to ASW patrol duties are usually set to "Elite" skill level, vs escorts which are mostly veteran units with a few elites here and there. Elite is to make them skilled in hunting subs and not be easy targets. Forces Captain to use discretion.


What is next? More S boat? lol

Ordered 350 ft, rigged for silent running and depth charge.

0411 As BARB passed 275 feet, heard torpedoes impact at bearing 330
estimated range 4000 yards. Submerged submarine detected same
bearing. Appears QUEENFISH or TUNNY's torpedoes found their mark,
again!


0414 BARB at 350 ft. Escort passed above, did not drop depth charges.
Rushed on and dropped on bearing of submerged submarine. TUNNY or
QUEENFISH were in for it.

USS Snapper Interior
 

My skipper recently transferred from USS S-28 (OnePunch) to the USS Snapper (SS-185). Sent out to the Solomons on his first war patrol with the Snapper, he sank 2 IJN Kuma-class Lt Cruisers and a destroyer escort in night action in 'The Slot'.


Here are some shots of the Snapper's interior, courtesy of the Fleet Interiors mod and a little adjusting:

(Close call while leaving Saipan!)



March 3, 1945
_____________

Departed PEARL HARBOR in accordance with COMSUBPAC Operation Order #65-45, en route to the west coast of KYUSHU via SAIPAN to form coordinated attack group with TINOSA and SPADEFISH, with Commanding Officer TINOSA as group commander.


March 3-14
___________

En route SAIPAN, conducted training en route. Averaged three dives, one battle problem per day. Studied many patrol reports and "BUSHIDO" to get back in trim after a long lay off.



March 15
_________

0810 While approaching Garapan Harbor, Saipan,
spotted large formation of B-29 heavy bombers approaching
for landing, likely returning from night time raid over Japan.
(Aircraft Contact No.1) (B-24's substituting for B-29's, since do not have
B-29 in SH 4 at this time)


0945 Docked at Saipan.
Topped off fuel and provisions.

2000 Departed Saipan at dusk for Patrol Area NINE.

2101 Trim dive.

2105 Sound reported a submerged submarine bearing 070 short range, closing!. TIRANTE at 75 ft. Rigged for silent running.
(Ship Contact No.1)

2107 Torpedo noises detected on sound bearing 030! Ordered 100 ft,
emergency! Appeared that a undetected enemy submarine fired
torpedoes at TIRANTE, which was saved by her evening. post refuel trim
dive. (Shocked as did not expect any AI enemy submarines to be in are
at this point, but shows why must remain vigilant. Trim dive saved my
boat)


2140 Lost sound contact with submerged submarine.
Last known bearing 240, estimated range 5000 yards.


March 16

0135 Depth charge explosions visible astern, DE
appears to have discovered a submerged submarine.
(Seems the patrolling DE's spotted the AI sub and attacked.
With external cam off, all could do was see flashes distant and listen on
hydrophones to explosions.


0200 Lost contact with DE's astern. Continued on patrol area,
with caution.
