Lockheed Martin received an $850 million contract modification from the U.S. Navy on 10 July 2026 to advance design and development of the Trident II D5 Life Extension 2 program. The funding accelerates D5LE2 modernization, extending service life and enhancing capabilities of the sea-based leg of the U.S. nuclear triad. This modification follows the Department of War’s April 2026 announcement of award intent and sustains critical national deterrence infrastructure. Work continues at Titusville, Florida, supporting submarine-launched ballistic missile reliability for operators. The award reinforces Lockheed Martin’s role in delivering next-generation sea-based deterrent capabilities while expanding workforce capacity to meet program milestones.
