OHIO CLASS SUBMARINE FIRST DEPLOYMENT FULL
OHIO CLASS SUBMARINE FIRST DEPLOYMENT SERIES

Using advanced technology in propellants, micro-electronics and new weight-saving materials, the Trident I C4 missile incorporated the multiple independently-targeted vehicle capability of its predecessor Poseidon and provided an astounding range of more than 4,000 nautical miles with a full payload. The Trident I C4 missiles were the longest continuously operated Fleet Ballistic Missiles ever deployed by the U.S.

The Poseidon was declared operational on March 31, 1971, and was deployed aboard all 31 Lafayette Class submarines. The first submarine-based test launch occurred on August 3, 1970, from SSBN 627 James Madison. The first Poseidon test launch occurred on August 16, 1968. Poseidon carried twice the payload of the Polaris A3 with significantly improved accuracy. The Poseidon, despite being 20 inches wider in diameter, 36 inches longer and approximately 30,000 pounds heavier, fit into the same 16 launch tubes that carried Polaris.

The next generation of fleet ballistic missiles to follow Polaris was the Poseidon C3 missile.

deployment of the Polaris missile series ended with the retirement of the A3 in 1979. Subsequent Polaris missiles, the A2 and A3, increased the range and thus the operating area of the stealthy deterrent. The A1's first successful underwater launch from a submarine on July 20, 1960, brought to fruition a remarkable Navy and industry research and development effort begun only four years earlier. A two-stage ballistic missile with a range of 1,200 nautical miles, the A1 was powered by solid fuel rocket motors and guided by a self-contained inertial guidance system independent of external commands or control. An unarmed Trident II D5 launches from the Ohio-class ballistic missile submarine USS Louisiana from waters near San Diego, Sept. The first Fleet Ballistic Missile (FBM) developed and deployed by the United States was the Polaris A1 missile, named for the North Star. Jackson (SSBN-730) is set to leave the service in 2027.Columbia needs to deliver by the end of 2027. The Trident II D5 missile has achieved 188 successful test launches since design completion in 1989 - a record unmatched by any other large ballistic missile or space launch vehicle. Keeping to the schedule is key for the Navy as the first Ohio-class boomer USS Henry M. The FBM team continues to build on a remarkable mission success track record. The company also supplies technical and logistical support at sites where the missiles are deployed. Lockheed Martin Space Systems Company, the Navy's Trident missile prime contractor, developed and produced the missile and support equipment. First deployed in 1990, the Trident II D5 missile is currently aboard OHIO-class and British VANGUARD-class submarines. Navy's submarine-launched fleet ballistic missiles, following the highly successful Polaris, Poseidon, and Trident I C4 programs. The Trident II D5 is the latest generation of the U.S.
