Unarmed Trident missile launches from submarine.
PACIFIC OCEAN (March 1, 2011) An unarmed Trident II D5 missile launches from the Ohio-class fleet ballistic-missile submarine USS Nevada (SSBN 733) off the coast of Southern California. The test launch was part of the U.S. Navy Strategic Systems Programs demonstration and shakedown operation certification process. The successful launch certified the readiness of an SSBN crew and the operational performance of the submarine’s strategic weapons system before returning to operational availability. The launch was the 135th consecutive successful test flight. (U.S. Navy photo by Seaman Benjamin Crossley/Released)
