 Cheers bud.Finishing up the next report. Knocked out one convoy, one singleton, and hit another convoy leaving Rabaul from the south. Got two large AP's before running out of torps. 7 ships in all. Even had a possible encounter with a submerged sub, went down and quiet and let her pass. No clue whether she was friendly or not, but I didnt want to get close enough to find out. |

Terminated patrol. C. Weather Weather was overall favorable during this patrol. Heavy seas during the attacks during initial attacks on 17 December did complicate matters at times, but help SKATE escape prolonged depth charge attacks when force to dive. D. Attack Data Torpedo Attack Data Number of Torpedo Attacks: 6 Torpedoes Expended:24 Torpedo Hits:22 Torpedo Misses: 2 Torpedo Malfunctions: 1. Torpedo Attack No. 2 , see torpedo info below. Ships Sunk: 7 Ships damage: 0 Ships probably sunk: 0 Erratic #1 (at firing) Error: Circular Run Type MK 14-3A Serial No. 88456 Exploder Contact Serial No. 8856 Speed Setting High Depth 8 ft Method Single bearing-Periscope No.2-TDC Spread 0 Gyro 359 L Track 8 P Course 330 Range(from target) 1800 yards AOB (target) 88 P Speed(target) 9 knots Course (target) 101 Remark Torpedo was final one fired out of three in the attack. Torpedo veered to starboard, then circled back towards SKATE. An emergency descent to 100 feet was made. Torpedo made four passes directly above SKATE during this time. Eventually, torpedo expended it's fuel and sound lost contact, until it's explosion, likely from sinking deep. A definite close call for the boat and crew. Own Ships Data (at firing) Depth: 64 feet Course 095 Speed 2 knots Action taken Ordered 100 ft depth with high speed and minimum angle to avoid stern protruding and risk being struck by erratic torpedo.

E. Radar Performance of new SJ-1 Surface Search Radar was excellent. Typical target detection range was twelve nautical miles. The PPI scope is a 'game changer', as it provides awareness of the tactical situation previously desired, but not attainable. SD radar performance was overall excellent. Enemy Radar Believe enemy Akatsuki Class Destroyer encountered on 16/17 December was equipped with surface search radar as it detected during SKATE's attempts to follow up attack on damaged AK, twice. Range SKATE was detected at is unknown but estimated to be 5000-7000 yards. Do not believe the Chidori type escorts encountered were equipped at radar, but signaled to our presence by the Akatsuki DD. F. Radio Radio communications were excellent during the patrol. G. Sound Gear and Sound Conditions Sound gear functioned well overall. Sound conditions were excellent throughout patrol area for SKATE. The enemy seemed to have difficulty tracking SKATE when submerged deep, especially during rough sea conditions, thus rendering counter attacks relatively ineffective. H. Thermal Layers Thermal Layers were registered at 100, 192, 230, and 333 feet. I. Major Defects and Damage Skate was undamaged during this patrol and suffered no major defects in equipment. J. Anti-Submarine Countermeasures and Evasion In patrol area, encountered numerous two vessel patrols, typically of DD or DE type "sweeping" the northern approaches to Truk. Daily air patrols were flown and most days encountered, forcing SKATE to submerge, Enemy convoys were well escorted compared to those previously encountered, with three or even four escorts. One nemy DD (Akatsuki Class) on 17 December is believed to have bene equipped with radar detecting, and chasing off SKATE twice, forcing dives as SKATE could not out run the DD on the surface. Skate came under heavy gunfire from escorts and merchants during night surface attacks, but escaped harm. Enemy depth charges seemed to be the improved type as explosion seem larger and reach detonation depth quicker after launch, indicating heavier charge with higher sink rate. Evasion SKATE's standard evasion procedures worked well on this patrol. Upon evading enemy counter attacks when submerged, boat descended to depth of 450-500 feet initially, rigged for silent running and depth charge.Speed bursts are applied when required, such as when enemy vessel above dropping depth charges. Five to ten degrees or port or starboard rudder is applied at all times to prevent SKATE from sailing a straight, predictable course and to confuse enemy sound operators. Speed is kept at 2.5-3 knots, less then 100 RPM during silent running, aside from speed bursts when sound is obscured by enemy above and depth charge explosions. The deep diving capability of the Balao Class Submarine provides an excellent countermeasure to enemy sound and active searches. Avoided enemy air patrols by diving and surface patrols by diving or speeding away at high surface speed. K. Tidal Information Tidal information was as previously reported in the area. L. Navigational Aids No navigational aids were encountered in the open ocean patrol area assigned. M. Mines No mines were encountered on this patrol. N. Crew Crew performance on this patrol was excellent. One Officer and Six men achieved qualification in submarines during this patrol. Total crew aboard 72 Qualified in Submarines 48 (start of patrol) Qualified in Submarines at End of patrol 54 Officers and Chief Petty Officers for War Patrol Two LTCDR Ryan, Irvin T., USN Commanding Officer LT Hunter, Ronald F. USN Executive Officer LT(jg) Reeves III, John W.USN Dive/Engingeering Officer LT(jg) Wilson, Martin X. USN Torpedo/Gunnery Officer LT(jg) Morris, Walter J. USN Sound Officer LT(jg) Clancy, Frank E.

USN TM3c Molony, Royce L. USN MoMM3c Walker, Guyford T. USN MoMM3c Long, Anthony USN O. Health and Habitability Conditions were generally pleasant throughout the patrol. The fair weather and seas for most of patrol contributed to this. Meal preparation was excellent, the frozen filet mignon, frozen strawberries, and assorted fruits were a hit. With SKATE at sea during Christmas and New Years Holidays, special meals were prepared. Christmas dinner was Turkey, Ham, dressing, beets, potatoes, and gravy, with strawberry, cherry pie and ice cream. Our southern contingent (including ships cook) prepared inspired black eyed peas for New Years Day, with filet mignon served New Years Eve. Chief Kousamalkis's soda fountain, providing Coca Cola, was a big hit with the crew. All proceeds after costs are directed to ships recreation fund. P. Miles Steamed-Fuel Consumed Pearl Harbor to Johnston Island 888 miles 10244 Gallons Johnston Island to Patrol area 2858 miles 25888 gallons Patrol Area 5200 miles 48900 gallons Patrol Area to Johnston Island 2998 miles 29044 gallons Johnston Island to Pearl Harbor 888 miles 11100 gallons. Q. Duration Pearl Harbor to Johnston Island 2 days Johnston Island to Patrol Area 8 days Days in Patrol Area 20 days Patrol Area to Johnston Island 8 days Johnston Island to Pearl Harbor 10 days Days submerged 4 days Total duration of patrol 40 days. R. Factors in Duration Fuel 31200 gallons (prior to refueled at Johnston Island) Torpedoes 0 Food 21 days Factor in termination of patrol- All torpedoes expended. S. Remarks Another busy and successful patrol for SKATE and her crew. The SKATE has proven a fine example of the advtanges the Balao Class submarine provides in the war on enemy shipping. Coupled with improved torpedo performance, a sense of optimism among veteran crewmembers is present. The night surface attack has proven yet again an excellent method to interdict enemy shipping, especially now with the new SJ-1 radar and PPI scope. A hope for installation of a Radar Warning Receiver is present, since it appears enemy vessels are now coming equipped with surface search radar, such as the Akatsuki DD. SKATE was disappointed it did not contact the battleship reported to be transiting the area on 25 December. However, with seven ships sunk, including two large valuable tankers, for a total of nearly 50000 tons in enemy shipping, the boat and her crew are satisfied and ready for next patrol. |

Close star shells caused this?  tanker tanker tanker tanker ULTRA about Yamato. Unfortunately, did not locate her on patrol, I was in the area. Upon conclusion of patrol, I reloaded my last save day before message, went to area and found YAMATO. I attacked and scored five torpedo hits, fifth hit caused large explosions. Of course, her escorts then pushed me to 650 feet and beat my boat up with depth charges, but I survived. Yamato was damaged but not crippled, sound lost contact with her 2 hours after torpedo impact, making moderate speed.Why did I miss her on patrol? Found my navigation was slightly off, likely just missed radar contact with her and her escorts. How it goes sometimes. Note: This is a historical movement I actually added to TMO as part of my update. I forgot about it actually until ULTRA came along. In real life, on 25 December 1943 USS Skate SS-305, guided to position by an ULTRA (decryption of Japanese radio traffic) did in fact torpedo YAMATO North of Truk, as she returned from home islands on a supply mission causing serious damage with four MK 14 hits from stern tubes. Much as in real life, kind of a once in a lifetime chance in the sim now, in TMO anyways. A. Prologue Returned from patrol to Pearl Harbor Submarine Base, T.H. on 11 November 1943.

Terminated patrol. C. Weather Weather was overall favorable during this patrol. Heavy seas during the attacks during initial attacks on 17 December did complicate matters at times, but help SKATE escape prolonged depth charge attacks when force to dive. D. Attack Data Torpedo Attack Data Number of Torpedo Attacks: 6 Torpedoes Expended:24 Torpedo Hits:22 Torpedo Misses: 2 Torpedo Malfunctions: 1. Torpedo Attack No. 2 , see torpedo info below. Ships Sunk: 7 Ships damage: 0 Ships probably sunk: 0 Erratic #1 (at firing) Error: Circular Run Type MK 14-3A Serial No. 88456 Exploder Contact Serial No. 8856 Speed Setting High Depth 8 ft Method Single bearing-Periscope No.2-TDC Spread 0 Gyro 359 L Track 8 P Course 330 Range(from target) 1800 yards AOB (target) 88 P Speed(target) 9 knots Course (target) 101 Remark Torpedo was final one fired out of three in the attack. Torpedo veered to starboard, then circled back towards SKATE. An emergency descent to 100 feet was made. Torpedo made four passes directly above SKATE during this time. Eventually, torpedo expended it's fuel and sound lost contact, until it's explosion, likely from sinking deep. A definite close call for the boat and crew. Own Ships Data (at firing) Depth: 64 feet Course 095 Speed 2 knots Action taken Ordered 100 ft depth with high speed and minimum angle to avoid stern protruding and risk being struck by erratic torpedo.

E. Radar Performance of new SJ-1 Surface Search Radar was excellent. Typical target detection range was twelve nautical miles. The PPI scope is a 'game changer', as it provides awareness of the tactical situation previously desired, but not attainable. SD radar performance was overall excellent. Enemy Radar Believe enemy Akatsuki Class Destroyer encountered on 16/17 December was equipped with surface search radar as it detected during SKATE's attempts to follow up attack on damaged AK, twice. Range SKATE was detected at is unknown but estimated to be 5000-7000 yards. Do not believe the Chidori type escorts encountered were equipped at radar, but signaled to our presence by the Akatsuki DD. F. Radio Radio communications were excellent during the patrol. G. Sound Gear and Sound Conditions Sound gear functioned well overall. Sound conditions were excellent throughout patrol area for SKATE. The enemy seemed to have difficulty tracking SKATE when submerged deep, especially during rough sea conditions, thus rendering counter attacks relatively ineffective. H. Thermal Layers Thermal Layers were registered at 100, 192, 230, and 333 feet. I. Major Defects and Damage Skate was undamaged during this patrol and suffered no major defects in equipment. J. Anti-Submarine Countermeasures and Evasion In patrol area, encountered numerous two vessel patrols, typically of DD or DE type "sweeping" the northern approaches to Truk. Daily air patrols were flown and most days encountered, forcing SKATE to submerge, Enemy convoys were well escorted compared to those previously encountered, with three or even four escorts. One nemy DD (Akatsuki Class) on 17 December is believed to have bene equipped with radar detecting, and chasing off SKATE twice, forcing dives as SKATE could not out run the DD on the surface. Skate came under heavy gunfire from escorts and merchants during night surface attacks, but escaped harm. Enemy depth charges seemed to be the improved type as explosion seem larger and reach detonation depth quicker after launch, indicating heavier charge with higher sink rate. Evasion SKATE's standard evasion procedures worked well on this patrol. Upon evading enemy counter attacks when submerged, boat descended to depth of 450-500 feet initially, rigged for silent running and depth charge.Speed bursts are applied when required, such as when enemy vessel above dropping depth charges. Five to ten degrees or port or starboard rudder is applied at all times to prevent SKATE from sailing a straight, predictable course and to confuse enemy sound operators. Speed is kept at 2.5-3 knots, less then 100 RPM during silent running, aside from speed bursts when sound is obscured by enemy above and depth charge explosions. The deep diving capability of the Balao Class Submarine provides an excellent countermeasure to enemy sound and active searches. Avoided enemy air patrols by diving and surface patrols by diving or speeding away at high surface speed. K. Tidal Information Tidal information was as previously reported in the area. L. Navigational Aids No navigational aids were encountered in the open ocean patrol area assigned. M. Mines No mines were encountered on this patrol. N. Crew Crew performance on this patrol was excellent. One Officer and Six men achieved qualification in submarines during this patrol. Total crew aboard 72 Qualified in Submarines 48 (start of patrol) Qualified in Submarines at End of patrol 54 Officers and Chief Petty Officers for War Patrol Two LTCDR Ryan, Irvin T., USN Commanding Officer LT Hunter, Ronald F.

USN TM3c Molony, Royce L. USN MoMM3c Walker, Guyford T. USN MoMM3c Long, Anthony USN O. Health and Habitability Conditions were generally pleasant throughout the patrol. The fair weather and seas for most of patrol contributed to this. Meal preparation was excellent, the frozen filet mignon, frozen strawberries, and assorted fruits were a hit. With SKATE at sea during Christmas and New Years Holidays, special meals were prepared. Christmas dinner was Turkey, Ham, dressing, beets, potatoes, and gravy, with strawberry, cherry pie and ice cream. Our southern contingent (including ships cook) prepared inspired black eyed peas for New Years Day, with filet mignon served New Years Eve. Chief Kousamalkis's soda fountain, providing Coca Cola, was a big hit with the crew. All proceeds after costs are directed to ships recreation fund. P. Miles Steamed-Fuel Consumed Pearl Harbor to Johnston Island 888 miles 10244 Gallons Johnston Island to Patrol area 2858 miles 25888 gallons Patrol Area 5200 miles 48900 gallons Patrol Area to Johnston Island 2998 miles 29044 gallons Johnston Island to Pearl Harbor 888 miles 11100 gallons. Q. Duration Pearl Harbor to Johnston Island 2 days Johnston Island to Patrol Area 8 days Days in Patrol Area 20 days Patrol Area to Johnston Island 8 days Johnston Island to Pearl Harbor 10 days Days submerged 4 days Total duration of patrol 40 days. R. Factors in Duration Fuel 31200 gallons (prior to refueled at Johnston Island) Torpedoes 0 Food 21 days Factor in termination of patrol- All torpedoes expended. S. Remarks Another busy and successful patrol for SKATE and her crew. The SKATE has proven a fine example of the advtanges the Balao Class submarine provides in the war on enemy shipping. Coupled with improved torpedo performance, a sense of optimism among veteran crewmembers is present. The night surface attack has proven yet again an excellent method to interdict enemy shipping, especially now with the new SJ-1 radar and PPI scope. A hope for installation of a Radar Warning Receiver is present, since it appears enemy vessels are now coming equipped with surface search radar, such as the Akatsuki DD. SKATE was disappointed it did not contact the battleship reported to be transiting the area on 25 December. However, with seven ships sunk, including two large valuable tankers, for a total of nearly 50000 tons in enemy shipping, the boat and her crew are satisfied and ready for next patrol. |

 Good move to let the sub pass, if it was enemy, and likely was, hitting them them is pretty impossible (homing torpedo wont go after them, too quiet, trying to remedy that, for late war fun) unless get lucky. I have tried in testing on sonar bearings lol on one had stalking me off Marshall Islands. If they detect you, they will try and stalk you, get in range for a shot. They can make about 9 knots under water like a US sub can, but they do not have limited battery power lol. That one at Marshalls probably stalked me for over 24 hours, until I finally made a high speed run for half the day to open up distance. They will also respond when aircraft etc spot you. If it was friendly, well obvious do not want to torpedo them, would end your career. Turns out, fratricide is frowned upon in SH 4. lol How did you detect it? Curious? Sound catch it while submerged, on surface? In future, I want to see if can get a periscope modeled for the submerged subs, so sticks above water. Also, want add wakes to torpedoes. While Japanese torpedoes had minimal wake, they not not completely wakeless. For me, knowing they are lurking around and can torpedo, really adds to the sim. Make sure to do sound checks myself, trim dives, even sail on a zig zag now instead of strait course. First patrol in SKATE, trim dive saved me on the way from Midway to lifeguard station off Wake Island. Just after diving, I did a manual sound check and heard torpedoes coming in, went to 100 feet, silent running, they passed overhead. Sound then picked up the submarine. I had external cam off, so could only go on sound. Just wrapped up second patrol in SKATE, which I started on Thursday lol and posted report with some screen shots just a moment ago. Patrol was a busy one for shore, North of Truk December 1943-January 1944. Took down seven ships, five cargo, two tanker.. I was testing the longer sinking times mod ont his patrol with some modifications to it on this patrol, so not quite as easy to sink ships as was before, unless have volatile cargo like tankers, they still blow up nicely, as shown in screen shots. Kind of cool though, they will flood, go dead in water, list, took one an hour to sink. Depends where torpedo hits them etc. |

If I remember right, I was just north of the Admiralty/New Hanover gap heading toward Bismark Sea at night. I think I was at 32x TC as I was coming close to where I wanted to go fishing. I got a TC stutter (tell tale sign theres something close, one of those SH things I guess) that tipped me off to come out of TC. Went to sound and got something odd off starboard bow closing slow. I listened for a bit, but it was ridiculously hard to hear. Not screw sounds, but almost sounded electric, moving slow. At first I thought it was extremely far away but the contact bearing line on the map said it was within 2000 yds!!!!! Thought it could be only one thing, and went down quietly. Followed him cross my bow to port until he couldn't be picked up anymore. It was super dark with pretty big waves, so even if there were a scope popped up, I wouldnt ever see it. Stayed pretty cautious the rest of the time in that area for the time being lol. |

Won't let me access the files. Strange, did last time. Speaking of AI submarines, just had a run in with a friendly. Attacked a large convoy NW of Truk submerged, hit tanker sunk it. Before went deep after fourth torpedo hit tanker (went up after one but fired a spread since had to fire from 2100 yards instead of 1000) , about ten seconds after my last torpedo hit I heard explosions, sounded like torpedo impacts. , I was searching around and saw smoke but had to go deep as had a escort closing. Pretty soon, another ship sunk marker showed up on them map. Not in my log, was not me, as I fired four bow torpedoes and all hit target. This sunken vessel was astern of me. Sound sweep revealed presence of another submarine on same bearing and in general area of the sinking marker. Apparently a AI US submarine stumbled upon this convoy as well. I had the external camera off so couldn't take a look, heard it getting depth charged and fired on though. I have some screen shots will share once back in port, leaving sim running and don't want to tab out, screws sim up, especially since am leaving boat submerged. I surfaced and did an end around, making a night periscope attack (moon was out, clear, visibility too great with heavy escort screen for surface attack) and sure enough, another ship was missing, besides the tanker I sunk.

lol the friendly AI subs will catch you off guard for sure. I was like what the hell is that, took me a sec to say to "oh yea, friendly sub attacked". This is the first time I have had one surprised me like that in campaign. First time saw one attack was in testing in Sea of Japan in 1945. I set up a wolfpack attack on convoy, with ULTRA messages directing player and all in the campaign. At ambush point, knew they were there but waited until attacked, to provide distraction. This was tactic US wolf packs used in 1943-1945. Three boats, one would attack, then while being chased, next one would attack, then the next, would take turns basically. They sunk one an damaged one, while most escorts were distracted moved in on surface (night time) and attacked, sinking three ships in fairly quick succession. I had the external cam on for testing, watched the enemy attack the AI subs. Problem is they see them as surfaced units and fire guns at them, drop DC if get close enough. I had the AI subs run to an end point where they delete, to simulate their diving deep to evade. Escorts kept hunting for a few though, was pretty cool. In testing mission, saw one get sunk by gunfire and depth charges. A Kamikaze DD fired some rounds which landed close, one hit conning tower, then rolled above the sub and dropped three charges,saw the AI sub leak oil and sink. Unfortunately, due to some unresolved issues, did not fully implement wolfpacking into the campaign on this release, but planned for future to be a factor in 1944/45, somewhat in late 1943. Where player receives orders to a certain area as part of "coordinated attack group" . Have to get the surfaced AI US boats firing torpedoes and not causing a CTD. |

USS Tang First War Patrol 22 January-3 March 1944
TMO 2.5 Update with patch (patch not yet released)
100 difficulty, contacts, cams off. First patrol of USS Tang SS-306 (Balao) in TMO. Shadowing Tang's real first patrol, went to Wake Island for lifeguard duty for PBY strike(standing in by Coronado flying boats, which bombed Wake in Jan Feb 1944). then proceeded to Truk as Tang did, then on to Saipan and then ended patrol at Midway Island on Mar 3 1944, as Tang actually did. Some of the targets sunk were stand ins for those actually attacked by Tang such as convoy attacked on 17/18 Feb off Truk and 22 Feb off Saipan . I wrote the this report in O Kane's style, with some modification, after reading all of Tang's reports, which was different than that of other reports have read. Note, some ship names are different. To keep things fresh, using historical records I have renamed nearly all merchants in forthcoming patch of the TMO update. Also lowered tonnage as the average japanese merchant was not as large as in the first release. A16-3 U.S.S. TANG (SS 306) Serial 02 c/o Fleet Post Office CONFIDENTIAL San Francisco, California March 3, 1944 From: The Commanding Officer To : The Commander in Chief, United States Fleet Via : The Commander Submarine Division 141 The Commander Submarine Squadron 14 The Commander Submarine Force Pacific Fleet The Commander in Chief U.S. Pacific Fleet Subject: U.S.S. TANG (SS 306), Report of War Patrol #1. Enclosure: (A) Subject Report. (B) Track charts. (ComSubPac only) 1. Enclosure (A), covering the first war patrol of this vessel conducted in areas north and west of TRUK, and north and west of SAIPAN, during the period 22 January, 1944 to 3 March, 1944, is forwarded herewith. R.H. O'KANE Confidential U.S.S Tang (A) PROLOGUE After completion of trials December 1, 1943, trained eighteen days in San Diego area, Arrived Pearl January 8, 1944, and continued training through the 19th, having fired forty-three exercise torpedoes and conducted night approaches on approximately half the days underway. Boat provisioned and twenty four MK 14-3A torpedoes loaded. Ready for sea 22 January 1944. (B) NARRATIVE Jan 22-29 Left Pearl Harbor at noon on the 22nd and proceeded to WAKE ISLAND at one engine speed. Jan 29-Feb 5 Arrived off Wake Island at 1400 hours on 29 January, submerged assumed lifeguard station ten nautical miles ESE, closing to six miles and surfacing after night fall. At 0015 hours on Jan 30 SD radar detected the Coronado flying boats which passed over TANG and observed explosions from bombs and Anti-Aircraft fire from Wake Island. No bombers were damaged or shot down. Over next few days patrolled area submerged by day, surfaced at night. At 0025 hours on 5 February a second strike by Coronado flying boats occurred and TANG was on lifeguard station again. Again explosions and AA fire were clearly visible in the night. No bombers damaged. Fires were observed burning from Wake throughout the night. TANG released from lifeguard station at 0500 and set cours for patrol area. Feb 6-9 En route to patrol area North of Truk along the Japan-Truk sea lanes.No contacts except for SD radar at 1100 on Feb 8th and 1231 on Feb 9th. Submerged to avoid both aircraft. Feb 10 Received a contact report from COMSUBPAC regarding convoy from Guam to Truk and moved TANG to patrol off Ulul Island as this was likely course convoy would take, between Mogami and Gray Feather banks. Feb 11 Conducted surfaced search near a point seventy nautical miles NW of Ulul Island. Diving twice for patrol aircraft, indicating a possible clearing of the way for a forthcoming convoy. Attack #1 At 1908 hours on the eleventh, SJ Radar established contact with a convoy bearing 284 degrees at a distance of 28355 yards. Convoy was tracked on a base course of 150 at eleven and half knots, directly for the 'slot' between Mogami and Gray Feather banks off Ulul Island, inbound to Truk. As viewed on the radar PPI screen, convoy was a composed of five large ships with five to six escorts, likely indicating importance. TANG went to General-Quarters-Torpedo and closed on the surface at high speed, submerging to 450 ft to continue high speed speed run to close the distance for firing. Having successfully slipped through the escort screen, came to periscope depth at 2044 to find a tanker 2500 yards at bearing 040.A quick plot was initiated, and all bow tubes readied for firing. Tanker was identified as being of the 6046 ton HAKKO MARU class on course 150 at 11.5 knots.Torpedo depth was set to eight feet. At 2047, range 1900 AOB 89, fired tubes #1, #2, #3, #4 as individual shots at five second intervals, per TANG's firing doctrine . Points of aim were middle of target, middle of target, stern/stack/bow. At 2048:10 torpedo#1 hit the tanker as it attempted to take evasive action, having spotted the wakes of incoming torpedoes. The torpedo impact set off a massive chain reaction explosion of the tanker's fuel cargo. Torpedoes 2,3,4 all impacted of next fifteen seconds, leaving the tanker a flaming hulk, settling in the war. Observed tanker sinking until a PC/SC type escort bearing 185 was observed at 1400 yards closing. TANG went deep, rigged for depth charge, and silent running. The craft passed above and dropped a string of depth charges as TANG passed 335 ft, all exploded well above. At 2052, sound reported breaking up noises from bearing of stricken tanker. HAKKO MARU 6046 tons sunk,9-22 N 148-49 E. Over next two hours with TANG at depth of 500 feet, enemy searched and dropped charges but never located TANG. All clear after periscope and SJ sweep, surfaced at 2355 hours for end around and follow up attack. Feb 12 Continued pursuit for end around of convoy and follow up attack. While hoped for a night surface attack, the clear conditions, calm seas, heavy escort screen and moonlight night did not permit such tactics. Attack #2 Finally ahead of convoy, submerged for attack at 0630 hours. A SJ check showed convoy track shifted slightly towards TANG making a bow shot not possible with the flank escort nearby, so turned away to open range for stern shot. Went to 300 feet to avoid escort, which passed astern at estimated 700 yards.TANG came back to periscope depth and observed a sizeable AK. Stern tubes were made ready for firing and target tentatively identified at RYUSEI MARU 7797 tons on base course 155 11.5 knots. At 0705 fired stern tubes #7,8 (MK 14 3-A), range 2800 yards, AOB 91, torpedo depth ten feet. At 0707, both torpedoes' hit amidships of target, five seconds apart. A large fire was visible, appeared internal, with a large hole visible in the fading moonlight, extended from below waterline. Target took a list to starboard and slowed. Enemy escort vessels immediately began closing TANG's position. Tang rigged for depth charge and silent running and just before going deep, observed RYUSEI MARU 4797 tons sink, 8-14 N 149-28 E. As TANG passed 381 feet, a series of large depth charge explosions went off above, shaking the boat. TANG leveled off at 500 feet and began evasive movements. Multiple escorts hunted for TANG for next few hours, alternating attacks, gaining, losing, and regaining contact with TANG. Estimated 181 depth charges were dropped, a few close ones but TANG suffered no damage. At 1300 after some time elapsed since last contact, TANG secured General Quarters and remained at 500 ft until 1600. Attempted to surface to catch up with convoy but multiple aircraft and a surface patrol in the area forced TANG to submerged again until night fall, when TANG surfaced at 2230 and resumed patrol. Feb 13-16 Resumed patrol North and East of Truk for traffic approaching eastern entrance to the atoll. No contacts were made aside from SD contacts, for which TANG submerged to avoid. Submerged on morning of the sixteenth for patrol between Truk and Mogami-Gray Feather Banks. Feb 17 After surfacing at 2200 hours on the evening of the sixteenth, proceeded to patrol on surface along the Truk-Gray Feather, Mogami Banks shipping lanes. Attack #3 At 0245 on the seventeenth, SJ radar made contact on a convoy bearing 333 degrees at 24300 yards. TANG began closing immediately for night surface attack, called to General Quarters-Torpedo-Surface at 0259. Convoy was in single column with three large vessels and four or five escorts. At 0334 APR-1 Radar Warning Receiver detected radar emissions from convoy, a escorting DD was equipped with surface search radar. Convoy course 077 at a speed of eight knots. TANG worked ahead and to port side of convoy and moved in when port escort went on a wide sweep, leaving a temporary opening in the screen. At 0440 all bow tubes readied. Convoy has large AK forward trailed by large AK, which was selected as target. At 0454, with flank escort returning to position and closing TANG, fired Tube #1,#2, #3, #4, at AO identified as KENYO MARU-6486 tons. Range 3500 AOB 50 Torpedo depth 8 ft. All four torpedoes hit the AK's bow, as it slowed in an attempt to evade torpedoes, at 0458, causing large fire and leaving the bow of vessel a wreck and sinking. The lead AK spotted TANG on surface illuminating with spotlight and unleashing inaccurate gunfire as TANG raced across her stern, between her and bow of the stricken tanker to escape on other side of convoy, as a SC/PC type escort was astern pursuing TANG. As TANG was about to cross the AK's stern, noticed the masts and slender bow and heavy bow wake of a DE type vessel closing at high speed , crossing in front of the tanker. Turned TANG to port to minimize broadside and ordered a dive, under heavy fire TANG leveled off at periscope depth temporary and fired tube#5 in a 'snap shot' at the AK from astern 1800 yards AOB 125.Also, observed KENYO MARU slid below the waves. The DE closing in fast, pinging, TANG rigged for depth charge and silent running, large down angle at high speed.As TANG passed 250 feet, several depth charge explosions rocked the sub. Minor damage reported in after torpedo, engine room, and crew berthing. Minor damaged in conning tower. See Major Defects and Damage Section. Enemy began pinging at 0506, but did not locate TANG at her depth. Depth charge explosions heard in distance. KENYO MARU 6486 tons sunk at 8-15 N 149-55 E. At 0900, periscope and SJ sweep showed all clear. Secured Silent Running and General Quarters and surfaced. Upon surfacing, set course to assume station off Ulul Island for OPERATION HAILSTONE. TANG's assignment was to intercept shipping that may flee during or after the air strikes on Truk by our carriers. Multiple other submarines are operating in vicinity of Truk for this purpose as well as those specifically assigned to lifeguard duty for downed aircrews. Attack #4 At 1424 SJ made contact with two pips bearing 024 27,049 yards. Rapid bearing changing indicating fast moving vessels. TANG turned toward contact and at 1426 the APR-1 Radar Warning Receiver began to buzz as radar emissions from coming from the contacts bearing. TANG submerged along the projected track and soon identified a Naka Class CL with an Etorofu Class Type A escort vessel on course 331 at seventeen knots. These ships likely fled Truk Lagoon due to air strikes and were heading right for TANG Closed target and at 15:01 fired Tubes 3,4,5,6 at range of 1800 yards, AOB 80, torpedo depth 8 feet. Unknown to TANG, a PETE floatplane(spotted on observation to watch the torpedoes impact) , possibly from the CL, was closing above and alerted the enemy cruiser, which attempted evasive action. However, the movement was too late as torpedoes one and two slammed into the stern of the cruiser, which slowed, with a large fire (apparently internal) burning. Torpedo three hit just aft of the bow and torpedo four impacted under the first stack. The cruiser quickly lost way and settled in water, but a fire profusely burning at the stern. With the PETE overhead and the escort closing, TANG rigged for depth charge, silent running, and went deep. At 1504, as TANG passed 300 feet, there was a serious of massive explosions from the last bearing of the CL, followed by more at 1508 and sounds of a ships breaking up. Naka Class CL 5113 tons sunk at 8-45 N 149-22 E. At 1510, the pinging escort located TANG at 450 feet began dropping the first of over 150 depth charges over next six hours. TANG suffered serious damage during the attack (see Damage and Defects section) including flooding in conning tower, control room, and forward torpedo room after a close pattern at 1513, with TANG at a depth of 500 ft. Aft torpedo and engine rooms would also take on water after close charges at 1807.Finally, at 2101, with TANG at 611 feet, the enemy escort dropped its last charge and appeared to have lost contact with TANG. Escort continued to hunt the area as TANG, with batteries down to just 15 percent slipped away. Feb 18-19 Upon coming to periscope depth at 0030, we found that neither No.1 nor No.2 periscopes were operational, damaged in the depth charge attack. TANG eased to radar depth and detected three pips at 280, 311, 170 , all 10000-12000 yards off. APR-1 detected radar emissions from those bearings as well. TANG surfaced and set course to the north to conduct repairs and recharge batteries. By 0900 both periscopes were operational and TANG proceeded back to station. At 1101 on the eighteenth, SJ contact was made on column of ships bearing 000 26500 yards. TANG closed to find a Task Force of US BB(Iowa Class) , CA, CL , DD , sweeping area as part of HAILSTONE no doubt. Exchanged recognition signals and proceeded on surfaced patrol until diving to avoid SD Contact at 1833. Continued patrol north of Ulul Island through the nineteenth. Feb 20-21 Sent status report to COMBSUBPAC and at 0500 received orders to relocate to new area off Saipan. TANG set course at one engine speed for a position south of Aguijan Island. Feb 22-23 Patrolled area of Ajuigan Island, Mariana Islands, after arriving 1600 Feb 21 and through the day of the twenty-second. At 0500 SJ contact with two pips at 19000 yards. Upon investigation these pips were a patrol of two SC/PC type vessels, TANG avoided. Attack #5 At 2050 on the twenty second while making a dusk SJ sweep prior to surfacing, SJ made contacts with multiple pips. First two were at bearing 333 10500 yards. Two pips, appear similar to patrol encountered previously. Second set of pips bearing 046 26000 yards, appears to be convoy. Patrol consisting of two DE types passed in front of TANG at 2135 range 5000 yards. Convoy was soon passing too close to surface and too far to attack. TANG went deep to avoid flank escorting DD and surfaced at 2330 for end around. Upon surfacing, PPI provided picture of five large ships in single column spaced at one thousand yards with four escorts forward, port, starboard, and to the rear. By 0044 on the twenty-third, TANG was six thousand yard ahead of the convoy pacing, waiting for flank escort to leave a gap in the screen during his "sweep". Convoy on course 219 degrees at ten knots. At 0151 Radar reported and lookouts observed port flank escort leaving to make his sweep. TANG performed a "dipsy doodle" and turned back into convoy for a stern shot. At 0205 radar operator and looks out report DD on sweep returning to station at high speed. Thus, TANG selected the lead AK a larger one, estimated 6000 tons to target. At 0210 Fired stern tubes 7,8,9 range 2500 yards AOB 88 depth 10 ft at AK JOKUJA MARU 6640 tons. At 2012 all three torpedoes impacted target which quickly slowed and caught fire, decimated by the hits. AK then suffered a series of internal explosions, blowing the vessel apart. JOKUJA MARU 6640 tons quick sunk at 0215 14-19 N 144-59 E. The DD now rushed in following the fireworks courtesy of TANG and closing down TANG's stern fast, but not opened fire nor illuminating. Preparing for dive, fired tube 10 in a "down the throat shot" from 3000 yards at 0215. At 0216 torpedo missed. Ordered dive to 500 ft, rigged for silent running and depth charge. DD passed above at high speed went about 1000 yards and dropped depth charges. Believe his speed was so great overshot TANG. Pinging was heard sporadically but enemy never gained sound contact with TANG. At 0445 TANG surfaced and began the race to end around for a follow up attack. The flank DD provided excellent screen thwarting TANG's advance several times. However, by dawn TANG was ahead of convoy and approaching for dawn periscope attack. Attack #6 TANG submerged at 0930, seven nautical miles ahead of convoy. At 1005 observation, convoy track had shifted, forcing TANG to turn for stern shot. At 1009 escort began pinging. Targeting what appeared be an auxiliary cruiser, fired tubes 7,9 at 2500 yards AOB 82. At 1013 one torpedo impact heard. At 1014 depth charge attack began with large explosions, astern. TANG depth was 525 ft. 1019 massive series of explosions distant, possibly from vessel (presumed to be Aux Cruiser) hit by torpedo.Aikoku Maru Class Auxiliary Cruiser 14280 tons sunk at 13-46 N 144-27 E. The follow up depth charge attacks were not effective and always removed from TANG's location, at a depth of 525 ft. Secured General Quarters at 1128, maintained silent running. Throughout the day of the twenty-third when TANG would attempt to surface to pursue rest of convoy, heavy air cover from Saipan/Guam prevented surface running and was unable to regain contact with convoy. Terminated pursuit at 2355 hours. Surfaced at 2215 and proceeded to area 150 NM West of Saipan in are MAPLE GROVE. Feb 24 Attack#7 At 0111 on the twenty-fourth SJ radar made contact with a convoy at 13000 yards bearing 010. Convoy on course 052 at seven knots in single column one escort forward, one astern. TANG astern of convoy, raced up the starboard side at 9000 yards preparing for attack. Large AK, AO in rear of column. At 0200 fired tubes 1,2,3 range 2500 yards, AOB 75, torp depth 8 ft..all torpedoes expended. At 0202 all torpedoes hit target, which quickly caught fire and lost way. TANG was illuminated by rear AK and came under heavy fire as turned away, A few errant machine gun rounds were heard hitting the deck. The escorts gave chase but lost contact with TANG in the dark of night. SHOHEI MARU 7256 tons sunk 15-01 N 144-38 E, 60 NM West of Tinian Island. With all torpedoes expended, set course for Midway at 0300 on the twenty-fourth per operations order. 25 Feb- 3 Mar En route Midway. No enemy contacts except planes from Marcus Island on Feb 29th.

Each contact was escorted, two by radar equipped DD/DE/SC. Air patrols were a consistent irritant. The counter attack on the 17th by the ETORUFU class Escort (TYPE A) after sinking the CL was intense, persistent, and accurate, causing serious damage to TANG. The escort was obviously equipped with best sonar, passive, and active, as well as manned by a competent Captain and Crew. The depth charging lasted 6 and a half hours and over 150 depth charges were counted. Upon losing contact with TANG, the escort continued to hunt. Two warships believed to be PC types arrived on scene , most likely from Ulul Island. Likely aircraft were above during the daylight hours as well. When surfaced SJ radar had three surface contacts. Evasion TANG's evasion consisted of initial dive to 500 feet, rigged for silent running, with five to ten degrees port or starboard rudder applied at all times, to avoid traveling a strait course, and speed bursts of standard to flank speed as required, primarily when escort was passing above or depth charges were exploding and noise was temporarily masked. The intense depth charging forced TANG to 600 feet to get away from the enemy. Due to flooding, boat wen to 642 feet when damaged trim pump failed. Recovery was made and TANG leveled off at 611 feet, which escort lost contact. (K) MAJOR DEFECTS AND DAMAGE TANG suffered heavy damage from the depth charge attack on the afternoon of he 17th. Most serious was forward hull damage found upon inspection. Damage repaired during refit at Midway following patrol. Following damaged suffered on 2/7/44 . All damage repaired at sea unless otherwise noted. 1.Flooding-2 ft water in control room. 2.Flooding-1 ft water in conning tower. 3. Flooding-2 ft water in forward torpedo room. 4.Flooding-8 inches water in aft engine room. 5. Flooding-3 ft water in aft torpedo room. 6.Trimp Pump 7. Hydraulic pump 8. Bow Planes Transmission 9. Stern planes Transmission 10. Rudder Transmission 11. Compressor 12.Radio Receiver-destroyed, replaced at sea. 13.Forward Batteries-Damaged cells, unable to charge abovet 96 percent for duration of patrol. 14. Aft Battery-Damaged cells, unable t charge above 96 percent for duration of patrol. 15.Diesel Engines No. 1 and No. 3 damaged 16. Electric Motors No.2 and No. 4 damaged 17. Bow torpedo tubes #1-#6 damaged. #3 inoperable-repaired. 18. Stern torpedo tubes #7-#10 damaged. 19. Deck mounted hydrophone head damaged, partially functional duration of patrol. 20. No. 1 Observation Periscope disabled-repaired at sea. 21. No. 2 Attack Periscope disabled-repaired at sea. 22.Electrical shorts and grounds throughout boat 23. Piping and high pressure air line leaks throughout the boat. 24. SJ Radar Antenna . In spite of this serious damage, TANG was back at fighting trim within 72 hours, a testament to her crew. (L) RADIO Radio function was excellent until depth charge destroyed receiver. The replacement brought radio back to life. However, performance was degraded. (M) Sound Sound conditions were overall excellent. The damage to the topside mounted hydrophone -JP degraded performance to some degree, even after repairs made. (N) RADAR SJ-1 Radar performance was excellent, typically detecting targets at 25000-28000 yards. (O) Density Layers Density Layers were found at 100, 150, 223, and 290 ft.

USS Tang Second War Patrol 16 March-17 May 1944
TMO 2.5 Update with forthcoming patch.
100 difficulty, contacts off, cameras on for a change Edited report, some how left out some torpedo data See Attack Section. USS Tang SS-306 War Patrol Report Second War Patrol 16 March-17 May 1944 Area VESTIBLE-Philippine Sea. (A) PROLOGUE Returned from first war patrol on March 3, 1944 and docked at Midway Island. After repairs and refit, loaded sixteen MK 23-2 torpedoes in forward torpedo room and eight MK 18-2 torpedoes in stern tubes. Ready for sea March 16, 1944. (B) NARRATIVE March 16-25 On the morning of the sixteenth, departed Midway for assigned patrol area(Vestible) in the Philippine Sea. Conducted trim dive at 1300 with diving and attack drills from 1400-1630. Over next few days continued en route on steady speed in mostly calm weather of 14 knots. Arrived in patrol area on the evening of the twenty fifth. March 25-29 Conducted search of the area with no contacts during this period, aside from patrol planes on the twenty-seventh and twenty-ninth, which were avoided by submerging. March 30 Attack #1 At 0930 on the morning of the thirtieth, SJ made contact on multiple pips at 27345 yards. TANG increased speed and and headed for the contacts. Soon the PPI display showed a formation, that a long with rapidly changing bearing indicating high speed, indicated a task force or important convoy. APR-1 detected radar emissions from bearing of contacts further indicating warships. After racing at high speed to get ahead, TANG submerged and closed for an attack, going to General Quarters. Upon first observation, in the distance about six nautical miles, TANG could see the masts of warships, including in the distance, toward the rear of the single main column, the massive pagoda mast structure of a Japanese battleship. Others ahead in column appeared to be CA or CL with seven or eight DD providing a screen. TANG went to 200 feet and continued to close at high speed until 1500 yards off projected track, turned to course towards the targets and went to periscope depth. On observation task force appeared to be on course 000 at a speed of twenty knots. On subsequent observations, it appeared the task force's track had shifted towards TANG, requiring a turn to port off the track and switching to stern tube set up. On next observation, the BB was clearly visible and identified as a YAMATO Class Battleship of 63200 tons. A contact report was sent to COMBSUBPAC at 1147. Soon a DD was spotted racing up along side the starboard side of the main body, his track would put him right on top of TANG near time of firing. Gambling the high speed of the DD along with heavy seas would hinder his sound gear and preventing TANG's detection, ordered 100 ft depth and bow pointed towards DD, turning slowly to maintain small profile to beam in case of active sonar use. This depth would also allow TANG to return to periscope depth in time for an attack once DD had passed. DD passed off TANG's bow about 1200-1400 yards. TANG returned to periscope depth and readied all stern tubes. The BB was clearly visible in he scope. In the main body, a single column of three TAKAO Class CA leading the YAMATO Class BB. (TORPEDO ATTACK NO.1) At 1156, fired tubes 7,8,9,10 at BB. At 1159:30-1159:50, four torpedoes hit the BB. Explosions and fires were visible after hits, but vessel seemed to take the hits in stride. Preventing an immediate turn for follow up attack, three DD quickly honed on TANG, forcing TANG to rig for silent running, depth charge, and descend to 500 feet. The initial depth charge attack was accurate, persistent, and intense. TANG went to 575 feet and was able to evade the hunters after a couple of hours. At 1325, as TANG was ascending to periscope depth, apparently bombed by an aircraft at depth of 250 ft. TANG returned to 500 ft . Enemy DD's arrived in general area hunting for the submarine the aircraft bombed, but did not detect TANG. Finally at 1804, at periscope depth, to our surprise spotted The BB at bearing 300 9000 yards and apparently dead in the water or moving slowly. TANG went deep and began an approach from starboard side. At 1948, TANG was at periscope depth and just 2000 yards from the stricken BB,, which had a list and was dead in water, but afloat. A DD remained in the area about 4000 yards off searching. (ATTACK No.1-A) At 1950 TANG fired six MK 14-3A torpedoes, all of which hit. TANG went deep after observing impacts. The DD rushed in pinging, but never dropped charges as apparently did not locate TANG. TANG returned to periscope depth at 2035 and located the BB at 6000 yards with heavy list. The DD had since departed the area at high speed to catch up with the rest of the task force. Only #1 bow tube was reloaded(MK 23-2) at this point, so at 2037 fired one torpedo at target and turned to bring stern tubes to bear, firing four MK 18-2 torpedoes from stern tubes at 2041. All torpedoes impacted, fire visible in bow area, appeared internal. Heavy seas required TANG to to go deeper for torpedo reload. Prior to scope going under, observed a EMILY flying boat arriving in area bearing 200 8000 yards. TANG went to 300 feet to conduct reload. Half an hour later, came back to periscope depth and prepared to fire bow tubes that were reloaded. SD sweep showed two contacts circling the area at 8000-17000 yards. AS TANG was prepared to fire torpedoes, closing the firing point on the BB, it suddenly rolled over and capsized. The bottom of the hull clearly visible, the BB lingered for about ten minutes before finally disappearing beneath the waves. Time from first torpedo hit to sinking was nearly ten hours. A total of fifteen torpedo hits were obtained on the goliath vessel. The vessel is believed to the the second of the YAMATO Class Battleships, the MUSASHI. MUSASHI and the vessels contacted had fled PALAU in advance of the carrier air strikes (OPERATION DESCRATE). 3/30/1944 21:47 20-29N 133-59E YAMATO CLASS BATTLESHIP 63,200 tons SD contacts remained in the area until night fall. TANG surfaced at 2330 and departed area. March 31-12 May Patrol in area continued but with no further enemy contacts for duration of time on station, aside from SD contacts made with patrol aircraft. Departed area for Midway at midnight on the sixth of May. May 13-17 Docked at Midway on the morning of the thirteenth for fuel and departed for Pearl Harbor at 1300. Arrived Pearl Harbor 1600 on the seventeenth, terminated patrol. (C) WEATHER Weather conditions varied throughout this patrol in a vast open ocean area. Seas ranged from calm, almost flat like a lake to rough swells which tossed the boat about. Most intense weather was experienced April 20-22 with intense winds, rain, fog, and estimated twenty five foot seas. (D) TIDAL INFORMATION Normal for the area. (E) NAVIGATIONAL AIDES None sighted.

Target left with heavy starboard list. One hour after final (15th) torpedo hit, target capsized. Own Ship Data (at firing) Depth 60 ft Course 270 Speed 2 knots AOB 90 S (I) MINES No mines encountered. (J) ANTI-SUBMARINE AND EVASION TACTICS Enemy ASW in patrol area was conducted by patrol aircraft, likely from Iwo Jima or Bonin Islands, possibly Northern Mariana Islands. No surface patrols were encountered in the open ocean area TANG was assigned. Patrol planes en route to and from Midway were encountered off Marcus and Wake Islands. The one enemy counter attack endured, upon torpedoing the BB on March 30, was intense, persistent, albeit shorter in duration than expected. While no damage was suffered, the DD's kept TANG on the run and submerged deep. Evasion TANG followed standard evasion procedure by running silent at 500-575 feet, always with five to ten degrees rudder port or starboard at 2.5-3 knots, cautious to keep motors below 100 RPM. This evasion naturally proved successful with just a few charges coming close. TANG suffered minimal damage(See Major Defects and Damage) (K) MAJOR DEFECTS AND DAMAGE No major defects of damage occurred on this patrol. Depth charge attack of March 30 caused the following damage: 1.Hydraulic pump 2.SJ-1 Radar Cabinet 3. Dive planes transmission 4. Piping leaks various compartments 5. High pressure airline leaks. 6. Light bulbs and glass fixtures-various compartments. All damaged repaired at sea. (L) RADIO Radio function was excellent (M) RADAR SJ-1 Radar performance was excellent on this patrol. SD Radar performance was excellent on this patrol. (N) Sound Gear and Conditions Conditions were overall normal. Heavy seas naturally interfered with sound equipment. (O) DENISTY LAYERS Density layers were encountered at 144, 190, 260, 315 ft. (P) HEALTH, FOOD, and HABITABILITY Excellent (Q) PERSONNEL Men on Board------------------------72 Men Qualified at start of patrol ----24 Men Qualified at end of patrol------59 Man Unqualified on first patrol----- 6 Men Advanced in Rating------------18 (R) MILES STEAMED-FUEL USED Midway to Area 3290 miles 29500 gallons In Area 5,250 miles 51600 gallons Area to Midway 3500 miles 33956 gallons Midway to Pearl Harbor 1350 miles 13874 gallons (S) DURATION Midway to Area 10 days In Area 45 days Area to Midway 8 days Midway to Pearl Harbor 4 days Days Submerged 3 days Total Days on Patrol 67 days (T) FACTORS OF ENDURANCE Torpedoes Remaining 9 Fuel 11,570 Provisions 15 days Personnel Unlimited (U) REMARKS No contacts were made aside from the BB on March 30 in the area. A surprise considering assigned area contains known, very active shipping routes between home islands and Palau Islands. It is possible due to the air raids and mining associated with OPERATION DESECRATE halted traffic. The challenges associated with locating convoys in vast open ocean areas remain a factor, of course.
