Lockheed Martin Space has received a $90.2 million contract modification for “advanced design and development” work supporting the Navy’s Trident II D5 submarine-launched ballistic missile life extension program, the Pentagon said.
The $90,229,306 cost-plus-fixed-fee modification, posted by the Defense Department Sept. 4, supports the Trident II Life Extension 2 Strategic Systems Programs Alteration Advanced Design and Development Program.
Work will be performed primarily at Kings Bay, Ga., which accounts for 68% of the effort, followed by Cape Canaveral, Fla., at 25%, Bangor, Wash., at 5%, and Denver, Colo., at 1%. The remaining 1% will be conducted at other locations.
The work is expected to be completed by Sept. 30, 2030.
Fiscal 2026 weapons procurement funds from the Navy will cover the full value of the modification, with no funds scheduled to expire at the end of the fiscal year.
The award modifies a previous contract and was issued to Lockheed Martin on a sole-source basis under 10 U.S. Code 2304(a)(1). The opportunity was previously synopsized on the Systems for Award Management website, with one proposal received.
The Trident II D5 submarine-launched ballistic missile is a three-stage missile currently deployed on U.S. Ohio-class and U.K. Vanguard-class submarines and will be carried aboard U.S. Columbia-class and U.K. Dreadnought-class submarines in the future. According to Lockheed Martin, the aim of the Trident missile is to ensure the Columbia-class submarine’s strategic weapons system is credible until 2084.
The Trident II carries the W88 nuclear warhead. Currently, the Department of Energy’s National Nuclear Security Administration is modifying the W88, and completed the last production unit of the W88 Alteration 370 in December 2025.
