Tell us about your current patrol

[Bubblehead1980]

SH 3 has a similar thread which is active and interesting to read usually, have tried to get it going before with SH 4. LEts try again lol. Tell what is going on with your current patrol.


Mod: TMO 2.5 Update BH
Difficulty:100 , cams on contacts off.
Boat: USS Seal SS-183
Date: 15 August 1942
Time 0936
Location: Area B9 100 NM ESE Hainan Island, China, South China Sea.
Depth. 350 ft.


At 0733 n 15 August 1942, made morning trim dive. Sound sweep picked up prop noises bearing 345, distant. Surfaced and closed at high speed.

At 0807 sighted smoke of convoy. Contact report sent. Convoy sighted at 19-12 N 112 32-E off Hainan Island. Convoy course/speed estimated to be 104 degrees 8 knots. Battle Stations-Torpedo called and at 0810 submerged off convoy port side for attack Received reply to contact report at 0821 with orders to focus on tankers. Seal moved in to target mid sized tanker in port column.

0845 Convoy course 104 at 9 knots. All tubes readied for firing at 0850, set to minimum depth due to experiences on last patrol with deep running torpedoes.

At 853 fired four MK 14 torpedoes from bow tubes at tanker of AKEBONO MARU class 6839 tons.

Torpedo # 1 prematurely detonated 17 second after launch, torpedo #2 took erratic track to starboard, suffering apparent gyro failure(nearly impacted the freighter in column, passing just ahead. Torpedoes #3 and #4 tracked properly, but observed their wakes pass below target with not detonation. Suspect more deep running torpedo in spite of minimal depth setting.

The Fubuki Class destroyer escorting target closed in fast in the calm seas with optimal sound conditions. Seal went to 250 feet, rigged for silent running and depth charge.

Currently at 350, DD has been hunting for four hours now, seems to lose contact then comes back and drops a close one.


I am currently testing some modifications to TMO Update on this patrol

1. Longer Sinking Times by Bilge Rat, modified for TMO Update.

2. Torpedo malfunctions adjusted (premature chance reduce, deep runnig adjusted so it happens)

3. Crew AI visual sensors enhanced. Tired of crew being blind and not spotting targets lookouts would be able to see, especially the smoke. SO far its paid off, spotting smoke of convoys at 8-10 miles, I can see smoke, they can as well. (Well they see the ship but still)

4. Damage model adjustments.

5. Fixed the depth charge racks on Asashio and Yagumo class, they were off.

6. Depth Charge disturbance mod. Love The DarkWraiths Depth Charge disturbance mod but it seems too effective, nerfing enemy sensors. So tweaking the settings and trying it out on patrol.

Goal is to provide something simulating the real life advantage of water disturbances created by depth charge explosions, but to maintain the tough TMO escorts. So far in this attack think may have found it. Lets hope.

So there is my situation, typical for 1942. Great target, torpedoes malfunctioned so missed, and now being depth charged.

Just got done with this one:



Mod: TMO 2.5 Update BH
Difficulty:100 , contacts on.
Boat: USS SILVERSIDES SS-236
Date: 1 April 1943
Time 0712
Location: 14-39N, 137-59E (400 miles WNW of Guam).
Surfaced.

0016 Acquired “SJ” contact at 013r, range 9 miles. c/c to close and increased to full.

0123 “SJ” revealed a convoy of four possible AK’s (2x2) and possible escort at the lead moving course 030, 8 kts. Began end around to their starboard.

0307 Arrived in an attack position ahead of the convoy. Elected to attack on surface on the two near side MARU’s, the first unable to be classified, but estimated at 4,000 tons, the second later identified as a HAKUSIKA MARU of 8,000 tons.

0308 Escort crossed our bow, possibly an OTORI class DE. DE zigging at irregular intervals but did not detect us.

0313 Both MARUs in range, decided to engage far one first. Ordered all bow tubes set to 7 feet.

0315 Fired spread of 3 on surface, 5000 yds.

Changed firing point to close MARU, coming on at 3,700 yds.

0316 Fired spread of 3 on surface, 3700 yds.
Turned hard to port at flank to retrograde.

0318 Saw explosions on both targets. Only one sent to the rear MARU seemed to be a dud. Star clusters launched from one or more ships, but was not fired upon, presume were still undetected. Large fires engulfing deck of lead target and heavy starboard list on rear.

0323 Lead Maru sunk bow first. Continued evasion to the east. DE turned toward our general position with a heavy bow wake, still far off. DE continued searching far aft of us, dropping 4 depth charges presumably shallow. At 0340, c/c to the north to prosecute remaining targets, seemingly returning to their original base course while the DE proceeded to the southwest.

0400 Arrived in position for a follow-up stern surface attack. Both MARUs zigging wildly with a mean speed of 4 kts at 030. First MARU possibly identified as a ZINBU MARU of 7,000 tons. Opened stern tubes

and ordered depths of 7 feet.

0408 Fired spread of 4 on surface, range 5700 yds.
Turned hard to starboard at flank to retrograde.

0410 Saw two large sprays of water fly up near her stern, most likely broken air flasks from a dud, and suspect the other two missed to stern from her evasive zigs. c/c to perform end around and hit the convoy on their port side.

0432 Arrived in position for third attack, but DE had closed and we believe we were illuminated by her searchlight. Watched her come on at very high speed. Went deep to avoid.

0439 DE made one ineffective pass with echo-ranging and dropped a string of 5 depth charges aft of us, none were close. Sound was picking up engine sounds at high revolutions with no screw sounds to the south. Continued submerged on southerly course toward sound contact we believed was the initial target. At 0620, sighted HAKUSIKA MARU off port bow with crew on deck manning deck gun on her bow. MARU was still afloat with a significant list to starboard, but dead in the water. c/c to 090 to close and deliver a coups de grace.

0702 Fired submerged spread of 2, 1800 yds

0704 Sound heard dud torpedo impact.

0704 Heard heavy explosion, witnessed with scope. MARU quickly subsided, sinking by her stern.

0712 Surfaced and c/c to 310 at 9 kts.




Probably one of the more memorable attacks Ive made in a while. Im still apprehensive of getting too close with my pants down, but Im getting more and more used to the surface night attacks.

Very nice attack. Yes, the new ability to conduct surface attacks does take some getting use do lol. I look at it how real life captains did, while some took to it enthusiastically, some had to get their feet wet and ease into it. For accuracy, I close to 2000-2500 yards, typical firing range is 2300 yards but of course it is a risk. Depends on the conditions etc. as well.

USS Seal SS-183
Sixth War Patrol

Wednesday 4 November 1942
Ten days since departing Fremantle, Australia and five since stop at Darwin for fuel.
0700 hours
Position: 5-38 N 131 59 E 161 NM SSE of Angaur, Palau Islands in assigned patrol area. Submerged at 0650 to avoid SD contact at 8 NM closing fast.
Set course for patrolling the North, South and East, West approaches to Southern entrance of Palau anchorage.



Previous afternoon of 3 November, Seal made an SJ radar contact, which was spotted soon after and revealed to be a large merchant vessel. Tracked vessel and made submerged attack with stern tubes (TORPEDO ATTACK NO.1) but suffered two deep runners and two premature detonations.

Once the target, an AK of the KOBAYASHI MARU class, was at 8 NM (SJ range) , surfaced for end around. The zigs and speed changes led to a chase which persisted after nightfall. However, a submerged follow up attack was made at 2027 scoring two torpedo hits and ultimately sinking. the 9980 ton vessel.

Picking up from the previous attacks of 1 April 43. Already sent HAKUSIKA MARU & an unknown 4,000 ton MARU to the depths, and made another unsuccessful attack on a ZINBU and MOMOYAMA MARU while their OTORI escort attempted to catch us.


Mod: TMO 2.5 Update BH
Difficulty:100%, contacts on.
Boat: USS SILVERSIDES SS-236
Date: 1 April 1943


0712: Surfaced and c/c to 310 at 9 kts.

0828: Lookouts sighted masts on the horizon off the port bow, seems to be broadside moving to the south.

0851: Dove for “SD” contact closing fast. While under, picked up two sound contacts seemingly moving northeast. At periscope depth, sighted two smoke plumes off our port beam and continued on 030 submerged, suspecting these are the remnants of the night’s convoy.

1039: Surfaced and changed speed to full to end-around, keeping the contacts on “SJ”. Contacts tracked at 4-5 kts. at a mean course of 030 with regular zigs.

1112: c/c to 310 to close. Sighted masts coming on shortly thereafter.
Dove to periscope depth for submerged attack.

1221: In position for attack. Of the two contacts, the first is assuredly the ZINBU MARU from earlier, the trailing freighter looked similar to a MOMOYAMA MARU of 4,000 tons. The ZINBU looked to be toting a gun on her stern, the MOMOYAMA seemed unarmed, so decision was made to attack with torpedoes on the first and dash up for a surface deck gun attack on the second.

1228: Fired spread of 3 on ZINBU at 1,800 yds with a 355 gyro angle.

1229: Heavy explosion heard and seen on scope amidships. Two duds heard bounce off her hull shortly thereafter. ZINBU still coming on though with a slight list to starboard.

1229: Decided to hit her again at 1500 yds.
Fired # 4 tube.

1230: Believe the torpedo missed forward, as the MARU slowed significantly after being hit.
MOMOYAMA MARU overtook ZINBU on the right, bringing her to within 900 yds. of us. Decided to not engage with a torpedo as her speed has most likely increased and didn’t want to fire without sufficient data. However, as she passed, it was confirmed that she didn’t possess any defensive firepower, and we’d continue with our original plan. Continued on course submerged until on the ZINBU’s port beam to engage with guns. By this point, she was suffering from catastrophic list to starboard risking capsizing, but was still moving under her own power.

1253: Battle surfaced and engaged the ZINBU with 12 4” high explosive shells along her entire port side, sinking her at 1256. Immediately after ceasing fire on the ZINBU, increased speed to flank to run down the MOMOYAMA.

1302: Fired 25 4” shells into her port side from aft at 2000 yds. sinking her at 1305. Simultaneously, RADAR was picking up a fast moving pip on “SJ” closing on our position. Raced away at flank on course 345 to evade.

1309: Lookouts spotted the masts of the previous night’s DE at 6 miles away to 195t. Dove the boat to 220 feet to make use of the strong layer and continued on course at silent speed.
DE searched for 4 hours as we listened on gear. She dropped 7-9 depth charges well aft of us by at least 5,000 yds if not more. Not once were we detected.

1922: Surfaced.


End result: COB, ready the broom for affixing to the scope upon return to Brisbane; we've made a clean sweep of that convoy.

Nice. Well done.

i see they called the cavalry in(one of those changes I made, when it is more likely to happen if patrol is in reasonable range) , just made it a little too late to more than rescue survivors, this time.
