Lettens Jan26/12/2010On 25th February 1944, LtCdr Willard R. Laughon's USS RASHER (SS-269) intercepts a convoy consisting of RYUSEI MARU and TANGO MARU that is proceeding from Surabaya to Ambon escorted by minesweepers W-8 and W-11 and auxiliary subchaser TAKUNAN MARU No. 3.

RYUSEI MARU is carrying about 6600 men of various IJA units.

At 2045, Laughon torpedoes and sinks TANGO MARU about 25 miles N of Bali Island at 07-41N, 115-10E.

At 2225, Laughon sets up and fires four torpedoes at RYUSEI MARU. He gets three hits and she goes down at 07-55S, 115-15E taking 4,998 troops and crewmen with her.

At 0824, USN codebreakers intercept and decrypt a message that reads: "Subchaser No. 1 will proceed immediately to the position of the sinking of the RYUSEI MARU to rescue personnel.”

A point of interest: the first 25 ships built by this company, without exception, were all lost at sea or wrecked. Of the first 50 ships built only 3 would see a full life of service and make it to the breakers yard.
