Dive Sites in Guam, United States

The SMS Cormoran II, a German armed merchant raider (built 1909 as the Russian SS Rjasan), was scuttled by her own crew in Apra Harbor on 7 April 1917 rather than be surrendered when the US entered WWI. She lies on her port side in 24-40 m (80-130 ft), remarkably intact, with the engine room accessible through skylights. The WWII Japanese freighter Tokai Maru sank alongside her in 1943, and divers can touch both a WWI and WWII wreck simultaneously at about 29 m (95 ft) — unique in the world. An advanced boat dive with sheltered but often murky harbor conditions.

The Tokai Maru, a 134 m (440 ft) Japanese passenger-freighter built in 1930, was damaged by USS Flying Fish and finally sunk by USS Snapper in 1943 while anchored in Apra Harbor. She came to rest at an incline on her port side directly against the WWI German raider SMS Cormoran, making this the only place in the world where divers can touch wrecks from both World Wars at once (contact point about 29 m / 95 ft). The upper structure starts around 12-18 m with the bottom near 40 m; whip corals, blennies, nudibranchs and turtles populate the largely intact hull, and torpedo damage is visible on the bow and #4 hold.
