Summary of Operations 5/18/42 US SST Submarine Conversions: Conversion has been completed on two of the three US submarines available for conversion to transport subs (SST) – SS Argonaut and Narwhal being the two subs completing conversion. The third sub (SS Nautilus) is now at Pearl Harbor and just completed 4/42 upgrade (the decision to convert it to a SST made while its upgrade was in progress). SS Nautilus is being sent to the mainland US for conversion to a SST, this being done to conserve available shipyard capacity at Pearl Harbor. The decision to convert the subs to SST’s was reached based on (1) some points posted by Alfred on this subject of the use of these subs as SST’s he made about a month ago (in real time) and (2) I actually have a sufficient number of US fleet subs in service to where the three subs can be released for conversion to SST’s. As I examined Alfred’s points about uses of SST’s on the Allied side plus other possible uses I was beginning to see, doing the SST conversions on the subs started making much more sense. I have no immediate plans for any operations with them but SST Argonaut and Narwhal are being dispatched to the South Pacific theatre, to be joined by Nautilus when its conversion is completed. My reasoning being that the most likely operational use of SST’s in the short term will occur in the South Pacific. Japanese Home Islands: SS Spearfish reports contact with Jap transport south of Kyushu. AAR follows. -------------------------------------------------------------------------------- Sub attack near Kanoya at 106,66 (ESE of Amami Oshima) Japanese Ships AK Kyushu Maru (one hit, a dud) Allied Ships SS Spearfish AK Kyushu Maru is sighted by SS Spearfish SS Spearfish launches 4 torpedoes at AK Kyushu Maru -------------------------------------------------------------------------------- North Pacific: Sigint report entry for 5/17 indicates Jap radio transmissions intercepted from Paramushiro Jima. Detected status of Paramushiro Jima base shows no visible Jap activity or forces, also no evidence of expanded port or airfield facilities. Plans are underway to develop a support base for US submarine operations in the North Pacific theatre area, probable location is projected to be Dutch Harbor. 221 USN Base Force has been transferred from West Coast command to North Pacific theatre and is being brought up to full TOE strength. An AS is being dispatched to the North Pacific theatre for use at the planned support base. The North Pacific submarine base is planned to be used for supporting submarine ops off the Japanese Home Islands. South Pacific: Three Japanese amphibious TF’s reported unloading at Koumac. AAR’s of landing operations follow. -------------------------------------------------------------------------------- Amphibious Assault at Koumac TF 55 troops unloading over beach at Koumac, 113,156 Japanese ground losses: 931 casualties reported Squads: 2 destroyed, 64 disabled Non Combat: 0 destroyed, 1 disabled Engineers: 0 destroyed, 0 disabled Guns lost 7 (0 destroyed, 7 disabled) Vehicles lost 3 (0 destroyed, 3 disabled) 18 troops of a IJA Engineer Squad lost overboard during unload of 10th Div /1 19 troops of a IJA Infantry Squad lost in surf during unload of 10th Div /2 19 troops of a IJA Infantry Squad lost from landing craft during unload of 10th Div /4 Note: Jap 10th Infantry Division was reported at Truk on 4/16. Pillager had transferred 10 Division from the Kwantung Army for use in the South Pacific. -------------------------------------------------------------------------------- Amphibious Assault at Koumac TF 63 troops unloading over beach at Koumac, 113,156 Japanese ground losses: 603 casualties reported Squads: 0 destroyed, 61 disabled Non Combat: 0 destroyed, 20 disabled Engineers: 0 destroyed, 0 disabled Guns lost 17 (0 destroyed, 17 disabled) -------------------------------------------------------------------------------- Amphibious Assault at Koumac TF 162 troops unloading over beach at Koumac, 113,156 -------------------------------------------------------------------------------- TF 63 encounters mine field at Koumac (113,156) Japanese ground losses: 83 casualties reported Squads: 0 destroyed, 7 disabled Non Combat: 1 destroyed, 11 disabled Engineers: 0 destroyed, 0 disabled Guns lost 1 (0 destroyed, 1 disabled) 10 Support troops lost in surf during unload of 89th Nav Gd /2 Note: 89 Naval Guard appearing for the first time in the known Japanese OOB. -------------------------------------------------------------------------------- It turns out that Pillager’s timing of his Japanese assault to capture New Caledonia is virtually identical to that in our previous PBEM in CHS – the landing at Koumac in our last CHS match occurring on 5/21/42, in our AE match on 5/18. However, there is one important difference… Pillager landed at Koumac in our last CHS match following the Japanese capture of both Suva and Pago Pago (these captured during April 42). This time around, both Suva and Pago Pago remain in Allied control. Pillager’s advance in our CHS match to capture what eventually became his Japanese outer perimeter line moved from east to west (first capturing Canton Is, then Pago Pago, Suva and finally Noumea). This time around in AE he’s changed the sequence. No reports of the KB this game turn. There is a coastwatcher report of five unidentified Japanese ships at Belep Is (NW of Koumac) moving on a NW heading. A US S-class sub is due to arrive at Belep Is during resolution of the 5/19 game turn. Other Allied submarines remain in patrol areas to the south, southeast and east of Noumea. Current weather conditions over the Coral Sea and adjacent areas remain clear. Japanese LBA naval air strikes on transport ships unloading at Suva. Combat resolution replay shows the Jap air strikes approaching from a NW direction, indicating Luganville as the most likely origin of Jap bombers flying in the strike. AAR’s follow. -------------------------------------------------------------------------------- Morning Air attack on TF, at Suva (132,160) Weather in hex: Clear sky Japanese aircraft G4M1 Betty x 3 No Japanese losses Allied Ships xAK Steel Seafarer Aircraft Attacking: 3 x G4M1 Betty bombing from 6000 feet Naval Attack: 2 x 250 kg SAP Bomb, 4 x 60 kg GP Bomb Note: A similar afternoon raid with 4 x G4M1Betty occurred.
