A New Disaster
In 1982, the Grayback was engaged in an accident that resulted in the deaths of five Navy divers. This was the second tragedy to strike the ship. After participating in a training dive, the men involved returned to the vessel, which was sailing in Subic Bay, near the Philippine island of Luzon at the time of the incident. They perished, however, when a critical ventilation valve failed to function correctly in the decompression room where they were trapped.
