The final resting place of USS Perch (SS 176) has reportedly been found in the Java Sea by divers looking for the wreck of the cruiser HMS Exeter. The details can be found at the On Eternal Patrol website, along with several pictures (including this one):
Unlike with the recently-found graves of USS Wahoo (SS 238), USS Lagarto (SS 371), and USS Grunion (SS 216), the details of the final action of the Perch were well known. Perch was scuttled by her crew on March 3, 1942, after being severely damaged during a horrific depth charge attack two days earlier. The crew was taken prisoner -- six Submariners died during 3 1/2 years in a Japanese POW camp, but 53 survived.
Bell-ringer 0602 22 Jan: A commenter pointed out that I had the designation on the Perch wrong in the title to the post ("SSN" vs. "SS") -- it's fixed now.
