On 19 July 1943, LTjg Roy S. Whitcomb flying a PBM-3C “Mariner” dropped six depth charges that sank U-513. Whitcomb saw 15-20 survivors in the water after the sinking and dropped some life belts and rafts to them. BARNEGAT eventually picked up the survivors the next day.
Interesting info. I didn’t even think about a Mariner !
Obviously, no one is going to attempt salvage as its a war grave. Also pretty deep for recreational divers to plunder.
I used to work for a compay using the old Glen Martin plant to make construction office type trailers. >PS
