Lockheed Martin has received an $850 million contract from the U.S. Navy to advance the modernization of the Trident II D5 submarine-launched ballistic missile. The award, announced on July 10, 2026, funds the next phase of the missile's life extension program, which aims to sustain and upgrade the sea-based leg of the U.S. nuclear deterrent through the 2040s.

The contract will also enable the company to expand its workforce, according to Lockheed Martin. The Trident II D5 is deployed on Ohio-class submarines and is also used by the United Kingdom's Royal Navy. The life extension program includes upgrades to guidance systems, propulsion, and other components to ensure reliability and performance as the missiles age.

This award follows previous contracts under the same program, reflecting sustained investment in strategic deterrence capabilities. Lockheed Martin is the prime contractor for the Trident II D5, which has been in service since 1990.
