Legend:

Laid down means that the ship's construction was officially started by laying down the keel (often just a single steel beam but could also mean the first of many pre-fabricated sections).

Launched means that the ship was launched from its shipyard, it then began its fitting out period (installation of smaller systems, weapons etc.) - in many yards the ships were launched very complete and needed little work afterwards.

Commissioned is when the navy takes the ship officially over and gives command of it to its new captain.

Schoeni, USN) is damaged when she is rammed by (most likely) the Japanese merchant Mayasan Maru in position 19°11'N, 122°38'E. Apogon is forced to terminate her patrol. The convoy attacked was made up of the landing craft depot and repair ship Tamatsu Maru (9589 GRT, built 1943), the army cargo ships / merchants Kashii Maru (6825 GRT, built 1936), Tozan Maru (6500 GRT, built 1938), Nissho Maru (6526 GRT, built 1939), Mayasan Maru (9433 GRT, built 1942), Mizuho Maru (8506 GRT, built 1912), Arabia Maru (9480 GRT, built 1918) and the tanker Nichiran Maru (6503 GRT, built 1939). They were escorted by the corvettes Kaibokan 11, Kaibokan 20, Kaibokan 26 and Kaibokan 28 and submarine chaser Ch-28 (all offsite links). (All times are zone I, -9) 11 July 1944 2239 hours - Received a convoy report from USS Thresher. Set course to intercept. 2314 hours - In position 19°51'N, 123°04'E made SJ contact bearing 273°, range 29800 yards. Went to full speed on all four engines to get ahead and cross to the starboard flank. 2345 hours - Guardfish reported she was also in contact. 12 July 1944 0046 hours - Sighted ship bearing 270°, range 8500 yards. This ship was about 5 nautical miles ahead of the convoy and was first thought to be Thresher. When range was closed to 6900 yards it was seen to be an escort vessel. Opened out the range. 0207 hours - Received orders for a coordinated attack on the convoy. 0227 hours - Reversed course for an approach on the convoy. Dived 17000 yards ahead of the convoy as there were two escorts. 0240 hours - Passed submerged between the two escorts that were heard pinging. The convoy could now be seen to be in three columns. The port column was seen to contain three merchant vessels as was the centre column. Apogon was dead ahead of the starboard column that contained two merchants. Planned to fire 6 bow torpedoes at the leading ship in the centre column and then fire the stern tubes at the starboard column. 0255 hours - Swung right for the attack on the centre column. 0304 hours - In position 19°11'N, 122°38'E commenced firing 6 bow torpedoes from 2000 yards. No explosions were heard after the expected running range. Shortly afterwards 3 explosions were heard with 8 to 10 second intervals. It was thought possible that hits were obtained in the far port column. One of the merchants in the centre column must have seen the periscope as he had turned towards and was now very close. Apogon went deep but none the less she was rammed. Water entered the conning tower through the periscope and the SJ mast fitting. A few seconds later the first of seven depth charges went off. The first two were very close. Apogon went as deep as 430 feet. Despite 4 escorts in the area she managed to slip away. Repairs were done during the day and Apogon surfaced at 2042 hours when it was found that all periscopes and the radar mast were bent at an angle of 47°. Patrol had to be abandoned and coourse was set towards Pearl Harbour.
