About Japanese Salvage Tug (Wreck)
Japanese Salvage Tug (Wreck) is a WWII wreck dive in Apra Harbor that rewards experienced divers with a classic deep-boat profile, broken steel structure, and open-water circuiting around one of Guam's best-known history sites. It is a wreck-first dive rather than a penetration site, so the planning focus is on clean buoyancy, gas management, and a calm boat run from the harbor.
