Impossible mission?! (Part 5)
26 Dec 1941 06:40
My NO has provided the coordinates for the sinking of Kiturin Maru: 132°03’E, 33°27’N. 06:45 I have ordered ahead one third and a new depth of 150 ft. Course is 359°. Now we wait it out. 09:05 We have been running north for two and a half hours, gaining 6 NM from the sinking. I have ordered a course change to 065°. Hydrophone shows no sign of a response yet from enemy forces. 10:45 Sunrise according to the Nautical Almanac. 14:00 132°12’E, 33°37’N. We’re over 14 NM from the sinking, and still no response. Are the IJN asleep? 14:35 132°13’E, 33°37’N. I have ordered a course change to 270°. 15:09 Hydrophone has detected a warship bearing 263, long range. 15:30 Sound contact now bearing 207. On a course opposite to ours. My SO is tracking it. 15:47 Sound contact now bearing 170, still increasing range. I’ve ordered my SO back to normal sweep. 16:00 Hydrophone contact lost on warship. 16:21 New sound contact bearing 122. Sounds like the same warship to me, obviously searching for us. My SO is tracking this contact. 16:30 Contact now bearing 102, closing, medium speed. I have ordered silent running. 16:40 Contact bearing 060, moving away. 17:00 Contact now bearing 026, moving away. Most of First and Third Watches are sleeping. That’s good -- I’ll want them well rested and alert for tonight! 17:37 Contact lost bearing 018. I have secured from silent running. 18:08 Soundings show only 65 ft under our keel, so I’ve ordered a new depth of 100 ft. 19:10 I have picked up the warship on hydrophone again, bearing 005. The SO cannot yet distinguish it -- he clearly requires a lot more experience or training! 19:15 Contact now bears 014. Appears to be moving northwards. 19:40 Contact now bearing 028. 20:10 Contact now very faint at bearing 040. 20:30 132°02’E, 33°37’N. Depth under the keel is down to 62 ft. I’m changing course southwards to deeper water. New course 195°. The Hoyo Strait is about 18 NM ahead. Sunset should be in a few minutes. It should be dark enough by about 21:30 to 22:00 to contemplate surfacing. 20:36 Sunset, according to the Nautical Almanac. 21:00 Hydrophone has picked up an indeterminate contact at 355. We shall proceed with extreme caution -- it might be a stationary enemy just listening for an unsuspecting submarine! I shall bear away to westwards a little to open the range to this possible contact. If necessary, I shall stay submerged at silent running -- we still have over 50% of our battery capacity, but the air is getting a little bit stuffy, with CO2 reading just above 30. 21:20 The possible hydrophone contact is bearing 310 from our new course. Projected, that puts it directly in line with Hoyo Strait. Have the Japanese stationed a picket there? I guess we’ll find out! 22:00 132°00’E, 33°35’N. I am coming to periscope depth. 22:03 Our anomalous hydrophone contact has become clearer -- I do believe we have an enemy submarine in our vicinity, bearing 275, which is no longer in line with Hoyo Strait. I’ve ordered silent running. 22:15 Our “friend” now bears 256, apparently moving eastwards relative to us. I am returning to our plotted course, at 188°, hoping to move through his baffles. 22:32 Contact now bears 277, slowly increasing range. 22:45 Contact now bearing 258. 23:00 Contact now bearing 251, getting fainter. He might be coming about. The next few plot lines on the chart should show that. 23:15 Contact now bearing 245. Faint. No other contacts - it sounds clear ahead. 23:30 Contact now bearing 243. Very faint. He has definitely changed course, possibly coming back towards us. I have ended silent running. 23:37 131°59’E, 33°32’N. I have conducted a periscope sweep -- clear! Apart from our “friend” there are no hydrophone contacts. I have ordered the boat to surface, ahead full, course 188°! 23:45 Weather is still clear and settled. Pity. I could have done with a storm right about now! 27 Dec 1941 00:40 131°59’E, 33°19’N. We are passing through the Hoyo Strait. We made our turn to a course of 325° at 131°58’E, 33°21’N. In the moonlight I have spotted a shore emplacement on the island on the west side of the Strait, and another on the mainland beyond. No sign of activity at either one. Perhaps we’ve caught them asleep? I’ll maintain ahead full until we've gained more range. 01:00 I have ordered ahead standard, to conserve fuel and make us a little more stealthy. 01:05 A binocular sweep shows no sign of enemy vessels ahead, or any pursuit from behind. 01:50 132°08’E, 33°07’N. We have turned to a new course of 112°. At this rate we should be out of the Bungo Suido in about two hours. These waters were infested with fishing boats when we last passed through here. There’s no sign of them, now. Perhaps bringing the war to their home has put some fear into their hearts! 02:23 132°14’E, 33°04’N. Changed course to 184°. 02:27 Hydrophone contact ahead. Warship bearing 351, long range, constant distance. I knew this was too good to last. But, we are in good shape, with batteries recharged above 80%. We have detected only one warship, so we should be able to avoid him. 02:44 I have spotted two distant ships in binoculars, bearing 350, long range. I have ordered periscope depth and silent running. We proceed with utmost caution from here. 02:50 The enemy is patrolling the centre of the entrance to Bungo Suido. I have ordered a change of course to 214°, to the west side of the channel, to maximise our separation from them, and a new depth of 120 ft. 03:09 One warship is closing our position, slowing down. I have ordered all stop. 03:18 Hydrophone contact bearing 032, medium speed, closing. 03:20 Active sonar! Ahead flank, hard to port! New depth 200 ft. 03:23 We have taken major damage from multiple depth charges - flooding, forward batteries -- much more. I have blown ballast to halt our sinking. 03:28 We are being attacked again! 03:29 Multiple close depth charges. I have blown ballast again to control sinking. 03:33 Active sonar again. We are sinking. I have blown ballast for a third time! Flank speed gives us only 2 to 5 kts. I am attempting to reach shallow water to abandon ship. But we are under attack for a third time! 03:37 Another six depth charges, but no further damage. 03:38 Blown ballast for a fourth time. We don’t have much compressed air left! More active sonar! Making only 2 kts at flank speed. 03:42 We are sinking again. 03:43 I have blown ballast for a fifth time! 03:45 We are under attack again! Making only 1 kt at flank speed. 03:48 We have struck the bottom. Depth 260 ft. Still alive! I have ordered all stop. Latest attack was only one relatively distant depth charge! 03:51 Forward torpedo room is pumping out water. The forward dive planes transmission is shot. The enemy is attacking again, directly overhead. Four depth charges that stirred us a little, but otherwise no new damage. 03:57 We are under attack again. Only three depth charges, no further damage. Depth gauge shows 270 ft. 03:59 More active sonar. Hopefully we are now mimicking a big rock! My NO reckons we are at 132°12’E, 33°00’N. 04:03 Five more depth charges, but no damage. We are probably too deep! But he knows we’re around here, somewhere. 04:06 More active sonar. My crew is holding up well. Several injuries, mostly minor, but no fatalities. Water is being pumped out of the forward torpedo room. Forward batteries are under repair, but that is a slow job. We had some flooding in the control room earlier, but that has been pumped out. It looks like the forward part of my boat took the brunt of the damage, but all bulkheads are intact. Biggest concern is that our compressed air is down to only 18 per cent, and slowly decreasing. We must have a slight leak somewhere. 04:07 Five more depth charges. A little shaken, but no additional damage. 04:09 Active sonar. 04:11 We are under attack again. Only two depth charges nearby, and three further away. 04:15 Active sonar. We are under attack again. Only three depth charges, two somewhat distant, one closer, but obviously not deep enough. 04:19 More active sonar. 04:20 Another attack. 04:21 Massive explosion nearby. Damage taken … [CTD] NOTE: Unfortunately, at this point I had a CTD. Rather than returning to a save file, I regard USS Nautilus as lost with all hands, 27 Dec, 1941. |

Ahhhh almost made it, but that is the nature of the beast I really enjoyed the patrol reports on this, kept it interesting. I think the Inland Sea areas may be too lightly defended in early war. I mean, I wanted it to reflect when Japan beefed up against submarine incursion as war went on, so in later periods its much more difficult but may be too lightly defended, esp in terms of mines controlling traffic. Something I will work out. I left it a lone because I assumed like me, most people just disregarded those orders. Again, you kept it interesting. I hate you CTD but that does happen when sitting on the bottom sometimes, in stock or mods. Devs were idiotic in not designing it where subs can set on the bottom. They take hull damage and being depth charged when on bottom san "sink" you into the seafloor which will eventually cause a CTD. Again, really enjoyed the reports though. What is next? New career? Same class or boat/time period or moving on ? |

USS BARB SS-220 Convoy Battle January 23, 1944
TMO Update V2.0
100 difficulty, cams off, map contacts on. I had to start career over due to discovered defect in damage model while at sea which involved removing the mod and making changes, so had to scrap the saved game. Started over, with BARB SS-220 again. Same time period, same area. ___________________________________________ USS Barb SS-220 19 January ____________ En route to patrol area. Course 271 degrees Speed 14 knots Curiously, no aircraft contacts as transited North of Wake and Marcus Islands last few days. Can only surmise recent carrier air strikes have neutralized the increasingly isolated islands as air bases. However, we remain alert for contacts. 0940 Dive 1001 Surfaced 20 January ____________ En route to patrol area. Course 271 degrees Speed 14 knots 0945 Dive 1005 Surfaced 1233 Spotted vessel bearing 333 16202 yards (SJ range) off Sofu Gan. Possible picket or weather vessel. Spotted Sofu Gan. (Ship Contact No.1) 1234 Dive 1236 Depth 150 ft. Speed 6 kts closed target on course 245. 1239 GENERAL QUARTERS-TORPEDO 1348 Periscope depth. Course 198 Speed 2.5 kts Observed a weather tug/picket anchored 5200 yards SE Sofu Gan. Continued approach for torpedo attack. 1357 Periscope depth 64 ft. As scope was raising, three large explosions to port rocked BARB. Spotted BETTY speeding along at 300 ft, climbing. Apparently BARB spotted during approach. Ordered 200 feet. No damage reported. Vessel fired at our periscope as went down. (Aircraft Contact No.1) 1402 While at 200 ft, aircraft depth charged BARB again. Charges exploded above. Ordered 300 ft. Tug heard underway on sound. 1450- Attempted to rise to periscope depth several times for attack on tug. 1700 However, aircraft remained in area preventing this. Tug was underway and maneuvered out of range. 1705 Secured GQ. 2234 Surfaced 21 January ____________ Course 265 degrees Speed 10.5 knots until dawn, increased to 14.5 knots until night fall. 0936 SD contact 18228 yds. Night flyer closing, fast! (Aircraft Contact No.2) 0939 Series of large explosions heard, astern. Given still dark and not likely BARB was sighted, likely that aircraft equipped with radar. 1113 Just after dawn, came to periscope depth. 1130 Surfaced 1539 SD contact 19950 yds closing, fast! Dive (Aircraft Contact No.3) 1542 Depth 150 ft. 1544 Explosions of depth charges/bombs audible through hull, not close. BARB really stirred the hornets nest as believed radar equipped aircraft dispatched to search by day and night for submarine contact off Sofu Gan. This is slowly our transit and it is regrettable we were contacted before entering patrol area. 1600 Turned to course 180 4 kts submerged until dark. Course change meant to confuse enemy searches. 2146 Periscope Depth. SD mast extended. 2230 Surfaced 22 January _____________ En route assigned area. Course 220 Speed 10 kts 0000 Entered Area CORRIDOR I adjacent to our assigned area. 0300 Increased speed to 15.5 kts. 0500 Turned to Course 260 10 kts 0901 Spotted surfaced submarine bearing 096 at 6500 yds. Appeared to be GATO Class, Likely TRIGGER as transiting her assigned area. Unable to exchange recognition signals, turned to course 180 at flank speed to put her astern. (Ship Contact No.2) 1103 Dive 1133 Surfaced 1135 Course 261 Speed 14 kts. 23 January _____________ 0000 Entered Area 8, began North-South patrol line along suspected shipping route. 0010 Seas picked up. Strong chop but not heavy. Clear skies, low moonlight, Winds at 17.50 kts direction 114 degrees. Last edited by Bubblehead1980; 02-27-22 at 07:05 AM. |

TMO Update V2.0
100 difficulty Cameras off, map contacts on. January 1944 in Area 8... 23 January _____________ TORPEDO ATTACK NO.1 0000 Entered Area 8, began North-South patrol line along suspected shipping route. 0010 Seas picked up. Strong chop but not heavy. Clear skies, low moonlight, Winds at 17.50 kts direction 114 degrees. 0100 SJ contacts bearing 355 28500 yds. Multiple pips, appeared to be convoy. Course 310 at speed 17 kts to intercept. Tracking party called to stations. 0109 Increased to Flank speed to close. 0114 Slowed to 15.5 kts. 0115 GENERAL QUARTERS-TORPEDO-SURFACE 0124 Spotted convoy bearing 235 10000 yds Course 133 degrees Speed 10 knots 0125 Sent Contact Report to COMSUBPAC Convoy Sighted 28-49N 132-39E in Area 8 Estimated Course 133 degrees Estimated Course 10 kts. 0132 3000 yards off to port of convoy track. Convoy appeared to be six merchants in loose formation with one escort forward, one astern. 0136 Forward escort identified as MIKURA Type B Escort Vessel Rear escort appears to be DE type. 0149 Near firing point, convoy made what appeared to be routine zig to SW. 0151 Flank speed, turned to course 105 to pull away from convoy. Rear escort, began high speed sweep along port side of convoy BARB was not spotted, this was believed to be routine escort maneuver as convoy showed no sign of alert. 0153 Rear escort bearing 175 4000 yards. Identified as Otori Class Torpedo Boat/Escort. 0155 Paralleled convoy on course 188 to pull ahead for attack. 0345 Convoy zigged to port course 160. BARB maneuvered to regain position quickly to fire from starboard side of convoy. 0400 Fired Tubes 1,2,3 at Target No.1 :20 0400: Fired tubes 4,5,6 at Target No.2 45 0402 Torpedoes impacted Target No.1 Large fires observed on target. 0403 Torpedoes impacted Target No.2 Large fires observed on target. After torpedo impacts, BARB came under heavy machine gun, deck gun fire, illuminated by strong searchlights aboard Target No.2 (MIIKE MARU) during turn away. Lead MIKURA escort came aboard, fired two star shells above BARB and began closing at high speed. Several rounds of machine gun/auto cannon fire hit BARB's superstructure but caused no serious damage. Several deck gun splashes observed , closed about twenty yards off starboard beam during turn away. 0405 Otori Class Torpedo Boat rear escort observed pouring on the coals speeding BARB's way. The choppy seas made it initially difficult to reach above 19 kts during initial get away but 20 knts was reached. 0412 Otori bearing 180 fired several rounds forward guns Splashes landed well ahead of BARB. One flew low and heard it roar over the periscope shears, splashed into sea about thirty yards off port bow of BAR. However, range continued to open so remained on surface. 0415 Began end around for follow up attack. Observed AK AKAMA MARU 5425 tons sink at 28-32 N 132-38 E. 0416 Depth charge explosions observed/heard 6000 yards astern. Enemy believes BARB submerged. Poor whale/fish taking our punishment. 0421 Observed AK MIIKE MAR 11800 tons sink at 28-32 N 132-38 E. TORPEDO ATTACK NO.2 0426 Tracking large pip believed to be AK making a solo run from area. Bold strategy. BARB closed contact at high speed. 0450 Spotted AK bearing 292 10,170 yards. 0503 Turned about, began to back towards target for stern shot. 0525 Target identified as AK HIYAMA MARU 7145 tons. Course 160 Speed variations of 7-10 knots zigging along course. 0526 Report of enemy pip closing range fast on SJ radar, appears to be escort coming to join the party. 0538 AK HIYAMA MARU changed course 280, possibly to rejoin convoy. Escort closing high speed bearing 130 7000 yards Closing range fast. 0541 HIYAMA MARU suddenly turned hard starboard to course 345, instead of zigging back towards BARB as anticipated HIYAMA MARU increased speed to twenty knots ruining stern shot. Vessel also fired several rounds from her aft deck gun in BARB's direction. BARB turned to pursue, moving to her starboard to avoid oncoming escort now just 5000 yards bearing 335, identified as Otori Class Torpedo Boat. escort (interesting tactics AI pulled here) 0618 Unable to catch HIYAMA MARU, as rejoined other merchant vessels, another AK was on course to cross our stern for perfect setup. Switched targets to AK similar to JOKUJA MARU 7390 tons. 0630 JOKUJA MARU turned North, away from BARB. 0634 As pursuit of JOKUJA MARU was going on. HIYAMA MARU again towards BARB. 0636 Otori spotted bearing 170 5000 yards, closing. 0637 HIYAMA MARU turned away high speed, firing deck guns and machine guns/auto cannons at BARB. Star shell illuminated area. Otori observed heading BARB direction. Ordered flank speed on course 035 0640 Otori was now chasing BARB range 6000 yards bearing 180, closing. 0650 Otori slowed suddenly, then turned back for convoy. BARB secured GQ and ordered forward tubes reloaded. Would end around for follow up attack, before dawn if possible. This would give the convoy a chance to calm down. 0937 Regained SJ contact after end around. Bearing 009 28,350 yards. 0956 Ahead of convoy, waiting for anticipated dawn zig for dawn attack. Visibility now too great for surface attack. 1022 Convoy made dawn zig to SE. 1043 GENERAL QUARTERS-TORPEDO-SUBMERGED 1101 Submerged for attack. 1106 Depth 300 ft for high speed run to close range. 1128 Periscope depth. Observed convoy on course 160 degrees to being stern tubes to bear on convoy. 1148 Tubes, 7,8,9,10 made ready for firing. 1152 Fired tubes 7,8,9 1153 All three torpedoes impacted as aimed. 1154 Small fire observed, vessel lost way. Engine noises ceased on sound. 1155 List to starboard developed on target. 1156 Lifeboats (two) observed from AK KANAGA MARU. Vessel low in water, sinking on even keel. Pings. Otori observed closing, Mikura escort observed closing as well high speed. Ordered 300 ft, rigged for silent running and depth charge. 1157 Passed thermal layer 195 ft. 1159 Pinging 1202 DC explosions astern, not close. 1203 Enemy above to port. Splashes. 1204 DC explosions. Close. Real tooth shakers. BARB at 350 ft depth. Most charges seem above. 1206 Second escort above. Many splashes. DC explosions. All were above, not too close. 1207 BARB leveled off at 370 ft. 1209 Pinging 1211 Depth Charge explosions, distant. 1212 Sounds of ship breaking up audible on sound gear from last bearing of target attacked. 1213 Multiple DC explosions astern. Pinging from closing escort. 1215 Pinging on short scale. Enemy closing high speed. 1216 Enemy above. Many splashes. 1217 DC explosions. 1221 Pinging. Distant DC explosions. BARB at 375 ft 1223 Enemy crossing bow above. One DC explosion, above aft. 1224 One DC explosion to port. 1226 Pinging. 1227 Enemy crossing bow, above. Splashes. Ordered AHEAD FLANK! BARB at 382 ft. Boat shaken by DC explosions. 1230 Pinging 1238 Distant DC explosions 1248 Pinging. More distant DC explosions. 1251 Enemy above. Splashes. BARB at depth of 390 ft 1252 DC explosions. 1310 Sound reported enemy heading away at high speed. 1332 Believe one escort departed to rejoin convoy. Other remained in area estimated 5000 yards, hunting. Occasional ping heard but did not appear to have contact with BARB. 1416 Secured GQ Escort remains in area hunting. Maintained Silent Running. Course 256 Speed 2.5 kts Depth 390 ft. 1500 Damage assessment show BARB faired well in depth charge attack. Only some light bulbs and glass fixture busted. Minor piping and air line leaks in conning tower and control room. 1510 Enemy remains in area about 7000-10000 yards astern. Occasional sporadic explosions heard. 1630 Turned to course 332 degrees 1945 Lost Sound contact. Secured Silent Running. 1948 Tubes 7,8,9 ordered reloaded. BARB to depth of 300 ft. 2306 Periscope depth. Night settled in. All clear. Seas remain choppy. 2308 Radar depth for SJ/SD sweep. 2315 Surfaced. 24 January _____________ 0000 Position: 28-22N 132-23E Course 320 Speed 10 kts Proceeded to Northern section of Area 8.

What is also fascinating is the immediate pre-Pearl Harbor period, 1940-41, in the Pacific. The Roosevelt administration was sure that a showdown with Japan was coming, just not sure of exactly when and how it would start. But they got the basics right -- the Japanese offensive southwards. (The one bit they missed, of course was Pearl Harbor.) But they were already committing resources to beefing up defences across the Pacific, in the minor outlying American island territories like Wake, Midway, Palmyra, etc, and securing the maritime lines of communication to Australia, the Philippines, New Zealand. But what I've never heard about is what sort of operations the USN's submarine force was doing during that time, apart from sending extra subs to the Asiatic Fleet. The AF, especially, had a mission to protect American interests in China, especially in those areas affected by the Sino Japanese conflict. So AF subs were deployed to Chinese waters and ports on many occasions from 1937 to 1941. Presumably some of these included intelligence gathering to identify and record IJN forces engaged against the Chinese. (For instance, in October 1938 the British Royal Navy very cheekily sent the light cruiser HMS Birmingham unannounced into Amoy harbour, where a Japanese fleet of seven battleships, eight cruisers, plus destroyers and minelayers were deployed, most of which had never been seen by western observers because of Japanese naval secrecy since the 1920s. Every sailor on board who had a camera, or who could make decent sketches or drawings, lined the gunnels to record every possible detail of the Japanese ships, who's crews had most definitely been caught with their pants down!) There were also the Japanese occupations of the Paracel Islands in April 1939, and their involvement in the Spratlys from July 1937 leading to their occupation in March 1939, both in the South China Sea, the latter immediately adjacent to the Philippines. Surely the AF must have been interested in reconnoitring what the IJN was doing there. Similarly, the USN knew about Japanese naval deployments to, and naval facilities, in the Marshalls and Carolines and other island groups of the Japanese Mandate. Apart from the submarine "war patrols" from Pearl Harbor to Midway and Wake in 1941 in the weeks before the Japanese offensive, I do wonder if there were any intelligence gathering missions sent to reconnoitre such locations in 1941 especially. These could be interesting scenarios to play out in any pre-Pearl Harbor campaign starts in the next update to TMO. I've always felt it is very artificial that the game starts only on 7 Dec 1941. At the very least there should have been an option for a pre-war training campaign. |

That point had been attempted to be driven home, several time... the last iirc, was by Mitchell... the same guy that the B-25 bomber, was named for... like... 5 or so years, well before Pearl happened... Yeah, Pearl happened... *snorts* Pearl, was a definitive Bent over wearing a "come kick Me" written sheet of paper, scotch taped to the back of the Pac fleet anchored there... & am a firm believer, in that it was sent there, to exact such a reaction from IJN... in short, it was a deliberate poke the bear move. On the tail end of all the sanctioning that was leveled against Japan, already by that point. May have not been Roosevelt, himself... but someone in the higher ups... was the orchestrator of it... & Roosevelt, didn't quash it from happening. Is no way, He couldn't have known, otherwise... M. M.

You are a sucker for punishment for sure, esp in the S boats in this updated mod lol. Early war fascinates me as well, it was a interesting yet, depressing time frame for submariners though. I found it boring in original version (stock and all other mods) because AI was so easy, but changed that up in the update, AI is tougher, but not on the level of say later war ijn escorts. While I love early phase myself, I would encourage you to not miss out on other parts of the war in this update though, really is a lot of excitement and challenge. The ability to pull off historically accurate night surface attacks really brings 1944/45 alive. The revision to traffic in campaign, the ULTRA's on different ships etc. Just a lot to see and experience. Not sure if you read my post from earlier, but that was two attacks on a convoy in Jan 1944, sample of it. Real run starts in mid 1944 when japanese started running the major North/South convoys in a Alliedesque fashion...10-15 ships, 4-5 escorts, sometimes escort carriers, often time land and sea based air cover. With the night surface attacks, can get inside the convoy now undetected(in most cases), attack from within, as many boats did. Well, it was pretty apparent we would have to fighting Japanese in early 20th century after they defeated Russians are Battle of Tsushima.(glorious victory it was) and even more so by the 1930's so they reinforced overseas territories within realm of 1930's i.e. depression era budgets. Pearl was considered safe, out of reach of attack. Those who tried to raise the alarm were shut down. If I recall the Admiral who protested to Roosevelt about moving fleet from San Diego to Pearl Harbor was fired or "retired". I agree though, always though SH 4 should had option to start at least one month before Pearl Harbor. A pre pearl harbor start mod came out sometime ago but it was just a few days before the war started and has not been updated in quite a while. So building on that concept, there will be a pre war campaign start in next mod. Campaign will begin in June 1941 and new construction/seal trials for Tambor/Gar class will begin January 1941, west coast, maybe even east coast if have time to work the east coast in. Career starts will be for boats out of Pearl and Manila. Attacks on Pearl Harbor and Cavite are scripted in, worked fine. A lot of work getting that part in lol Prior to war, player has a variety of objectives from simulated defensive war patrols in area of Hawaii, Midway, Guam, Philippines, to participating in fleet problems with carrier and battleship task forces, homage to the original "fleet boat" concept. Also, some orders to observe japanese shipping in home islands, and in their overseas territories with orders to remain undetected. Propensity for hostility from Japanese units will be unpredictable as one may spot you and ignore you, other may attack you (accomplished same method as the US Friendly Fire in the mod). After oil embargo takes places in August 1941, tensions rise and higher propensity for hostile actions, which increase even more so as time goes on. Remember, this is 1941, before SD radar is available, so staying on the surface in daytime and remaining undetected, is almost impossible. Adds a lot to the challenge having to operate in the pre war-early war doctrine of submerge by day, surface by night when in enemy areas. Some fictional license (I've never read about this happening but figured could bring some variety) will be taken with limited special missions, inserting intel agents in places like Truk etc other parts of Japanese mandate, and then recovering them after X amount of time (pick them up in raft, can be rescued like a downed pilot) or being sent to recover them, as were previously inserted by another boat. Some photo missions (not hollywood, photo Tokyo Bay though lol) may pop up. I do have a one for S Boats to visit Shanghai area for a port visit, as they used to do prior to start of war in 1941 when Japanese took over completely. " I've played through June -December 1941 start of war once out of pearl and once out of manila to test, worked well overall, few things need to tweak, couple patrol objectives want to add, but it worked well. Obviously the pace is slower since not at war but is challenging from trying to always remain undetected in area, esp if trying to send contact reports on enemy task forces. Possibility of sighting their newest fleet carrier when out on sea trials in 1941 or the new battleship (Yamato) not aware of it (based on historical records of ship movements as are most of the major warship movements in the TMO Update) , is possible as well. Yet, can only document and send report, shadow, no attacking, unless you are attacked and even then only if in self defense. |

TMO Update BH V2.0
100 difficulty, cams off, map contacts off. USS BARB SS-220 Area CLOSET March 26, 1944 After several days of patrol in area with nothing but daily aircraft contacts and chasing a contact report which did not show up at expected rendezvous, either due to own navigation error or course change by convoy, possibly both, crew was going restless. Then on 26 March just after midnight, SJ made contact. 26 March ___________ TORPEDO ATTACK NO.1 0014 SJ contact bearing 007 28,355 yards Numerous pips, likely convoy, appears Northbound. (Ship Contact No.2) 0015 Increased speed 18 kts to intercept. 0025 GENERAL QUARTERS-TORPEDO-SURFACE 0026 Eight pips in two columns with one pip forward and one in rear, likely escorts. 0050 Spotted convoy bearing 040 9000 yards. 0052 Contact Report sent to COMSUBPAC Convoy Sighted 23-53N 131-47E Estimated Course 066 degrees Estimated Speed 9 kts. 0102 Lead escort is minesweeper. 0103 Spotted large Tanker similar to AKATSUKI MARU (11800 tons) Class. 0105 Directly astern of AKATSUKI MARU was a mid sized tanker similar to ICHIYU MARU (5115 tons) Class. 0112 APR-1 detecting radar emissions from astern of convoy. Rear escort appeared to have radar. 0117 Tubes 1,2,3,4,5,6 made ready to fire. Depth set for 8 ft. 0125 Fired Tubes 1,2,3 at ICHIYU MARU. Range 2893 yards. Fired Tubes 4,5,6 at AKATSUKI MARU. Range 2500 yards Torpedoes 1,2,3 impacted ICHIYU MARU. Massive fireball and explosions after second torpedo hit loaded tanker. Torpedoes 4,5,6 hit AKATSUKI MARU. First torpedo set off massive, skyward reaching fireball engulfing the entire vessel. Second and third torpedo hits were somewhat redundant, but further wrecked the vessel. 0138 During turned away, lead escort spotted BARB. BARB received some machine gun/Auto Cannon fire, few rounds heard stringed aft , starboard. No damage. Escort continued pursuit as second escort, with its radar signal sweeping BARB's area coming in fast. BARB making 21 kts plowing through seas to get away. 0145 Oddly, both escorts disengaged, returned to convoy. BARB moved for end around and follow up attack. 0146 AO AKATSUKI MARU 11800 tons sunk 23-52N 131-47E 0150 AO ICHIYU MARU 5115 tons sunk 23-51N 131-47E TORPEDO ATTACK NO.2 0247 Stern tubes brought to bear on convoy, approached large AK which suddenly turned hard away at high speed. BARB not detected, routine evasive maneuver. Switched setup on small AK believed to be CHOKO MARU 1800 tons. Unable to set up on others due to proximity to the radar equipped escort. APR-1 was buzzing at this time. 0250 Fired Torpedo Tube No. 10 at AK CHOKO MARU. 1950 yards. 0252 Torpedo impact! Large fire visible just forward of bridge structure. Large hole visible forward. Vessel appeared to be sinking. TORPEDO ATTACK NO. 3 0307 CHOKO MARU out of range. Spotted mid sized AK similar to MOMOYAMA MARU 4037 tons crossing stern of BARB. 0309 Fired tubes 7,8,9 at MOMOYAMA MARU. Range 2000 yards. 0313 Torpedoes missed! Based on sound, missed just astern. Speed setting in TDC was slightly too slow, perhaps should have been 5 kts instead of 4.5 kts. 0314 Pulled away from convoy to conduct torpedo reload as all tubes empty after three attacks with seven out of ten torpedoes hitting targets. Two tankers sunk, one AK damaged. 0315 APR-1 detected enemy radar emissions focusing on BARB's bearing. Escort, a unidentified DE type began closing at high speed. BARB increased to flank speed. 0323 DE turned back to convoy. 0330 Secured General Quarters. Torpedo reload ordered, all tubes. 0400 Convoy changed course to 040 degrees. 0530 Lost SJ contact with convoy, backtracking along course. 0600 Torpedo reload completed. 0610 Searching for convoy. |

War Patrol Day 1
United States Navy
Commander Submarines, Pacific Lieutenant Commander Straw Kalling, You have been approved for the command of USS S-31 (SS-136), a S-18 class submarine assigned to the Asiatic Fleet. Report for duty at Cavite Naval Base, Manila, Philippines, no later than December 8, 1941. ##### United States Navy Commander Submarines, Asiatic Fleet Operational Order, December 8 1941 TO: Straw Kalling, USS S-31 (SS-136) DEPART ON: December 9, 1941 Proceed to area Vineyard and conduct anti shipping operations within the designated area near the Celebes Sea for 5 days. OBJECTIVE: Patrol area Vineyard within the designated area near the Celebes Sea for 5 days. ##### Aboard USS S-31 (SS-136) 9 Dec 1941 13:02 - Cavite Naval Base War patrol Day 1. Ordered cast off from the tender, and ahead one third, set course to 270°. Departing on a war patrol in response to the Japanese attack. I have a crew of 54: five officers and 49 men, comprising four CPO, two PO1, eight PO2, six PO3, six S1c, and 23 S3c. There’s a band on the nearby quay, but I don’t know who they’re playing for. It can’t be us -- they’re facing the wrong way! 13:10 My nav officer will guide us out of Manila Bay. I haven’t sailed with him before, but he’s familiar with these waters. Especially the placement of the minefields at the entrance to the bay, off Corregidor. I’ve been briefed that they were deployed back in July, after Japan occupied southern French Indochina. Along with Hainan, the Paracels and the Spratleys, that gives them the potential to dominate the South China Sea. Much too close to our base for comfort. And now they’ve launched a major offensive! 13:12 Ahead two thirds. 14:20 Ahead standard. Our course is 235°. 14:44 We have sighted four PTBs ahead of us, crossing our bows. These guys are small and fast! I wouldn’t like to be on the receiving end of a salvo of their torpedoes -- they’re so hard to see until the last minute they could launch a devastating attack before you could bring guns to bear on them! 14:50 The PTBs have changed course, and are bearing away towards Corregidor. 16:03 We are in the channel between the minefields off Corregidor. I can see mines in the water to starboard, but not to port. My NO assures me they are there! I have also seen smoke rising in the channel between Corregidor and the Bataan Peninsula. That’s the heading the PTBs were on when we saw them over an hour ago. I hope none of them hit a mine! I know the PTBs were deployed here a couple of months ago. Surely they would have been briefed about the minefields? We have only six of them, so we need every single one intact! 16:08 We’ve made our final turn, on course at 242°, to pass between the minefields. Second watch is now on duty. Corregidor is an impressive bastion -- surely the IJN wouldn’t be foolish enough to try a naval assault here? 17:00 We are through the channel between the minefields and exiting Manila Bay. Still on course 242°, ahead standard. 17:42 We have come to new course 237°, ahead standard. I aim to skirt to NW of Lubang before turning SSE to pass through Mindoro Strait. We should make our turn in about four hours. 18:10 We have received Fox Traffic from COMSUBPAC: LARGE CONVOYS OF TRANSPORTS HAVE DEPARTS (sic) SOUTHERN FORMOSA LAST SEEN ON SOUTHERLY COURSE X UNITS IN AREA SHOULD INTERDICT X This is contrary to the orders from COMSUBAF that I sailed with just a few hours ago, to patrol south of Mindanao. Because of the enemy presence in the vicinity, I am observing strict radio silence. So, because it will take over three days to reach our patrol zone, I am making an executive decision to attempt to interdict, as COMSUBPAC says. I have informed my XO, and I am ordering an immediate change of course. We can always head down the east side of the Philippines afterwards to reach our patrol zone, admittedly some days later than intended! 18:15 We have changed course to 270°. We will turn northwards in a little over three hours. My NO has plotted a course to 120°E, 20° N. It will take us less than two days to get there, if we remain on the surface -- which I intend to do to expedite our passage, as long as we don’t encounter the enemy, especially air patrols. I just wish we could have been fitted with one of the SD radars that became available in recent months! 21:40 We have come about to 345°, ahead standard. Weather is clear with a 10 kt wind out of the north. |

Withers had 2 S-Boats, both badly in need of overhaul, out patrolling off western Luzon, near Manila Bay... the rest of the boats were anchored in Manila Harbor, Cavite, Sangley Point, Mariveles, or at Olangapo, undergoing a battery rebuild that was over six months late in scheduling... The AF had not done like a few of the Pearl boats, and therefore most did not have a clue as to what to expect on a real patrol, much less a wartime patrol. Both commands had quit any attempts to "spy" or recon on the Japanese, for fear of antagonizing them... They already did know where a lot of the Japanese resources were though, and with the War Warning message, the AF should have had boats off the coast of Indo-China and China proper at the least, so that they could see and accurately report movements. Same way with to the east of the Philippines. It was well established in military circles that the Japanese would shortly be the enemy, and that they would mount invasion from Palau, Japan, Okinawa, Formosa, Hainan and CamranhBay, at a minimum... see no evil, hear no evil, speak no evil, and you'll get your butt handed to you every time...
