Lockheed Martin will conduct sustainment services for the reentry sub-system of Minuteman III intercontinental ballistic missiles.

The U.S. Air Force contract carries an initial value of $109 million. Work will include repair, modification and testing of hardware and software components in the reentry system-reentry vehicle as well as related support equipment.

"This award represents an exciting new chapter in Lockheed Martin's 50-year partnership with the Air Force ICBM enterprise," said Doug Graham, vice president of ICBM and advanced programs, Lockheed Martin Space Systems Company. "This new contract will enable us to directly apply our specialized expertise to more effectively support this critical national mission area."

The contract has a one-year base period of performance and options for an additional four year. If all options are exercised, the total contract value would be $452 million.

Lockheed Martin said that work under the award would primarily be performed at Hill Air Force Base in Utah.
