USS Apogon

Bikini Atoll · Marshall Islands

The USS Apogon is a Tench-class submarine sunk during Operation Crossroads, now resting upright on the lagoon floor at 50 meters — one of only a handful of diveable submarines in the world. She sits intact with her conning tower rising to 38 meters, her torpedo tubes still loaded and open, and her interior accessible to technical divers through hatches that remain open after 80 years on the bottom. The compressed scale of a submarine makes every centimeter alive with encrusting coral, sponge, and the surreal juxtaposition of wartime hardware draped in tropical reef.
