Lockheed Martin has received a $12.5 million, one-year subcontract from Northrop Grumman Corporation for refurbishment of reentry vehicle arming and fuzing assemblies for the U.S. Air Force's Minuteman III Intercontinental Ballistic Missile (ICBM) system.

Under this subcontract, Lockheed Martin Space System's Valley Forge facility in King of Prussia, Pa., will replace components, refurbish and test the assemblies. The subcontract includes an option for a second year.

Under an earlier contract in 2009, Lockheed Martin successfully demonstrated the feasibility of the refurbishment effort. Lockheed Martin is the original equipment manufacturer for the arming and fuzing assembly.

"Lockheed Martin is committed to providing the U.S. Air Force Nuclear Weapons Center and the Air Force Global Strike Command user with our reentry systems domain expertise and high-quality engineering in support for the operational ICBM force," said Doug Graham, vice president of advanced programs, Strategic and Missile Defense Systems, Lockheed Martin Space Systems Company.

Lockheed Martin is a principal teammate to Northrop Grumman, the ICBM prime integration contractor for the U.S. Air Force. Lockheed Martin has supported the U.S.

ICBM force for more than 50 years, delivering Atlas, Titan and Peacekeeper missiles, reentry systems, and command and control ground systems, and has been the principal designer, manufacturer and sustainer of Minuteman III reentry systems since the 1960s.
