Lockheed Martin Space was awarded a contract modification, worth around $495 million, for Trident II (D5) missile production and deployed systems support.
The modification was awarded by the U.S. Navy’s Strategic Systems Programs Office in support of the UGM-133A Trident II submarine-launched ballistic missiles (SLBM) deployed on board the U.S. Navy and the UK Royal Navy ballistic missile submarines (SSBNs).
Work will be performed in Cape Canaveral, Florida (23%); Kings Bay, Georgia (19.5%); Bangor, Washington (19.4%); Sunnyvale, California (16.7%); Denver, Colorado (8%); Titusville, Florida (4.8%); Magna, Utah (2.7%); Orlando, Florida (1.3%); and other various locations (less than 1% each, 4.6% total), an is expected to be completed Sept. 30, 2024.
Trident II (D5) missiles are carried by 14 U.S Navy Ohio-class and 4 British Royal Navy Vanguard-class nuclear powered ballistic missile submarines. The Ohio-class SSBNs are able to carry 24 missiles each while Vanguard-class submarines can carry 16 missiles each.
The D5 is the sixth in a series of missile generations deployed since the sea-based deterrent program began 60 years ago. The Trident D5LE (life-extension) version will remain in service until 2042.
The missile has a range of 7,840 km with a full load and approx. 12,000 km with reduced load (exact is classified) with a speculated circular error probable (CEP) of 90 metres. The missile is guided with the MK 6 Astro-inertial guidance navigation system which is able to receive GPS updates.
