A UGM-133A "Trident II" ballistic missile is launched from the U.S. Navy "Ohio"-class ballistic missile submarine USS "West Virginia" (SSBN-736) during a missile test at the Atlantic Missile Range. The test flights were part of a demonstration and shakedown operation, which the U.S. Navy used to certify a submarine for deployment after a major overhaul. The missiles were converted into test configurations with kits containing range safety devices and flight telemetry instrumentation.
