U.S. Navy Awards $383M Contract to Lockheed Martin for Trident II Missile Upgrade

The U.S. Navy has awarded Lockheed Martin a $383 million contract modification to develop the Trident II D5 Life Extension 2 (D5LE2) missile, ensuring continued sea-based strategic deterrence.

The upgraded missile will be deployed on COLUMBIA-class ballistic missile submarines, maintaining the Trident II Strategic Weapons System (SWS)’ effectiveness through 2084.

The D5LE2 program aims to modernize the Trident II D5 missile, currently in service aboard U.S. OHIO-class and U.K. VANGUARD-class submarines. Lockheed Martin, responsible for developing and sustaining the missile under its Fleet Ballistic Missiles (FBM) program, will integrate digital technology and design enhancements.

The second life extension will help the U.S. and U.K. maintain credible deterrence under the Polaris Sales Agreement. The Trident II D5 remains a key component of U.S. and allied nuclear deterrence strategies, providing sea-based nuclear capability for decades.

To support the D5LE2 program, Lockheed Martin is constructing a 225,000-square-foot facility in Titusville, Florida, expanding its presence on the Space Coast. The facility will produce components for the upgraded submarine-launched ballistic missile (SLBM).

Operations at the new site are set to begin in 2027, aligning with the Navy’s long-term production needs for strategic deterrence.
