Lockheed Martin Receives $13.8M Mod in Support of Trident II (D5) Missile

Lockheed Martin Space is awarded a contract modification, worth around $13.8 million, for Trident II (D5) missile production and deployed systems support.

Fiscal 2020 weapons procurement (Navy) funds for the amount are being obligated on this award, none of which will expire at the end of the current fiscal year. This contract was awarded to the contractor on a sole-source basis under 10 U.S. Code 2304(c)(1) and was previously synopsized on the Federal Business Opportunities website. The U.S. Navy’s Strategic Systems Programs (SSP) office is the contracting activity.

Work will be performed in Cape Canaveral, Florida (62.3%); Sunnyvale, California (35.9%); and other various locations (less than 1% each; 1.8% total). Work is expected to be completed Sept. 30, 2024.

UGM-133A Trident II SLBM

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.

The missile has a maximum operational range of over 7,500 miles (12,000 km) and a CEP of 90 meters (the exact values are classified). The missile’s MK 6 Astro-inertial guidance navigation system is also able to receive GPS (Global Positioning System) updates.

The missiles deployed on U.S. submarines can be equipped with a Mark 5 MIRV warhead that can carry up to 8 W88 (475 kt) warheads, or a Mark 4 MIRV that can also carry 14 W76 (100 kt) warheads.

Trident II missiles are carried by 14 U.S. Navy Ohio-class and four UK Royal Navy Vanguard-class ballistic missile submarines (SSBNs), with 24 missiles on each Ohio class and 16 missiles on each Vanguard class.

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.
