Night dive on Sutsuki Maru, WWI design destroyer. According to Lance very fast. Was badly damaged in Battle of Coral Sea and brought back to Chuuk, where prow was patched.
Was used to help protect convoys from US submarines and has a couple of depth charges on back. Had an anti aircraft gun, and brought down a number of US planes during Hailstone, which led to a concentrated attack which destroyed and sank it.
Sits in less than 18m, night diving a wreck took some guts, as lots of narrow squeezes, and no ambient light. Also a fair amount of silt, which made finding way out kind of gnarly
