An unarmed Trident I C4 missile launches from the fleet ballistic missile submarine USS Daniel Boone (SSBN 629) off the coast of Cape Canaveral, Florida. Development on the Trident I C4 missile began in 1975 along with the construction of the first submarine to be fit for the Trident missile body. Today, the Sea-Based Strategic Deterrence mission continues. The current generation of submarine launched ballistic missile—the Trident II D5/D5LE—along with the Intercontinental ballistic missile and nuclear capable bombers create the nation’s strategic nuclear deterrence capability. The triad of capabilities – SLBMs, ICBMs and nuclear capable bombers – are each undergoing modernization to ensure our nation’s ability to serve as the backbone of our nation’s security. The U.S. Navy Strategic Systems Programs (SSP) mission remains ever vital for the safety and security of the U.S. and her citizens at home and abroad. (U.S. Navy Photo/Released)
