An unarmed Trident II D5LE missile launches from the Ohio-class ballistic missile submarine USS Wyoming off the coast of Cape Canaveral, Fla., during a test on Friday. The Pentagon has recently put Trident II D5 missiles through a life extension program to prevent potential aging and obsolescence impacts, and make the missiles usable until at least 2040. The test launch Friday marked the 184th successful missile test flight of the Trident II (D5 and D5LE) SWS. "This same team is now developing the next generation of the Trident Strategic Weapon System, which will extend our sea-based strategic deterrent through 2084," Wolfe added. Submarine Launched Ballistic Missiles make up approximately 70% of the sea-based leg of the nation's strategic nuclear deterrent triad, which also includes the U.S. Air Force's intercontinental ballistic missiles and nuclear-capable bombers.
