The U.S. Missile Defense Agency (MDA) recently awarded Lockheed Martin a follow-on contract potentially worth $515 million to continue development of the Terminal High Altitude Area Defense (THAAD) system, a regional interceptor system now being deployed, according to a March 26 company press release.

Lockheed Martin Space Systems of Denver is the prime contractor for the THAAD system, designed to destroy ballistic missiles both in and above the Earthโ€™s atmosphere. The advanced capability development contract is a five-year, indefinite delivery/indefinite quantity award, according to the press release.

An initial task order, valued at $66 million, provides three years of engineering and technical services, according to the press release. Those services include flight test planning, laboratory maintenance, studies and threat assessments.

The MDAโ€™s 2013 budget request for THAAD is $778 million, which is $221 million less than the 2012 appropriation, according to budget documents.

The THAAD system is designed to protect deployed U.S. and allied troops and population centers against short and intermediate-range ballistic missiles.

Lockheed Martin Missiles and Fire Control of Dallas performs most of the companyโ€™s work on the program.
