Lockheed Martin Space Systems is being awarded a modification to a previously awarded contract for Trident II (D5) submarine-launched ballistic missile (SLBM) deployed system support.
Â
The cost-plus-incentive-fee and cost-plus-fixed-fee contract modification, worth around $71.6 million, was awarded by U.S. Navy’s Strategic Systems Programs (SSP) located in Washington, DC.
Â
UGM-133A Trident II, or Trident D5 is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space Systems in Sunnyvale, California, and deployed with the American and British navies.
Â
It was first deployed in March 1990, and remains in service. The Trident II Strategic Weapons System is an improved SLBM with greater accuracy, payload, and range than the earlier Trident C-4. It is a key element of the U.S. strategic nuclear triad.
Â
The missile has a range of 4,230 nautical miles (7,840 km) with full load and approx. 7,500 mi (12,000 km)
with reduced load (exact is classified) with a speculated circular error probable (CEP) of 90 metres (300 ft)
Â
The missile is guided with the MK 6 Astro-inertial guidance navigation system which is able to receive GPS (Global Positioning System) updates.
Â
Trident II missiles are carried by 14 U.S Navy Ohio-class and 4 British Royal Navy Vanguard-class nuclear powered ballistic missile submarines (SSBN)
