Lockheed Martin (NYSE: LMT) will continue to manufacture submarine-launched ballistic missiles for the U.S. Navy and the government of U.K. under a four-year, $559.6M contract modification.
The company will also support both countries’ deployed Trident II D5 missile systems, the Department of Defense said Thursday.
The Navy will obligate $421.8M in fiscal 2019 weapons and “other” procurement funds at the time of award, while U.K will provide $137.8M on this modification.
Work is expected to conclude by Sept. 30, 2023.
Trident II D5 missiles are currently aboard U.S. Ohio-class and U.K. Vanguard-class submarines and designed to carry multiple independently targeted re-entry vehicle warheads.
