UGM-96 Trident I Submarine Nuclear Missile

First Deployed in 1979, the Trident I (C-4) is a submarine-launched ballistic missile (SLBM) designed by Lockheed Martin Space Systems and General Dynamics in the United States. The missile has multiple independently-targetable reentry vehicles (MIRV) capability. The Fleet Ballistic Missile (FBM) is armed with nuclear warheads and can be launched from U.S. Navy Ohio class nuclear-powered ballistic missile submarines (SSBN).

Trident missiles, with British warheads, are also carried by Royal Navy Vanguard class submarines. In 1990, the Trident II was first deployed on the USS Tennessee (SSBN 734). Trident II is larger and lighter than the Trident I. The Trident II also has a longer range than the Trident I.
