Through the 1960s to the 2000s Treasure Island, San Francisco and The Naval Damage Control Training Center, located in Philadelphia, Pennsylvania were home to the Navy’s damage control schools as well as the nuclear, biological, radiological and chemical warfare school, both primary schools of new hull maintenance technicians. Treasure Island continued to train new sailors in the art of damage control until the base was decommissioned in 1996. As of 2015, the damage control school is at Naval Station Great Lakes, and is on the same base as basic engineering common core and other A schools.
