Lockheed Martin has secured an USD 850 million contract modification from the U.S. Navy to continue design and development work on the Trident II D5 Life Extension 2 programme. The project supports the long-term modernization of the United States' sea-based nuclear deterrent through the 2040s and beyond.
Lockheed Martin has received an USD 850 million contract modification from the U.S. Navy to continue the design and development of the Trident II D5 Life Extension 2 (D5LE2) programme. According to official disclosures, the programme will further modernize the Trident II D5 strategic weapon system, extending its operational capability beyond the 2040s as part of the United States' nuclear deterrence strategy.
The contract supports ongoing upgrades to a missile system that serves as the sea-based component of the country's nuclear triad. By extending the system's service life, the programme is intended to maintain the reliability, effectiveness and operational readiness of the U.S. strategic deterrent while addressing evolving security requirements.
The award is significant for the U.S. defence industrial base, benefiting missile systems, advanced engineering, defence electronics and aerospace manufacturing. Programme activities will be carried out across multiple U.S. locations, supporting continued demand for highly skilled engineering and technical capabilities.
For defence contractors and investors, the contract reinforces sustained U.S. government spending on strategic weapons modernisation and long-term military capability development. Continued investment in nuclear deterrence programmes is expected to create opportunities across the defence supply chain and support future technology development initiatives.
Lockheed Martin is a U.S.-based aerospace and defence company that develops advanced military systems, aerospace platforms and security technologies. The company is a long-standing supplier to the U.S. Department of Defense across air, land, sea, space and missile defence programmes.
