TASC Inc., of Chantilly, Va., was awarded a U.S. Air Force contract worth as much as $198 million to provide technical assistance and advisory services supporting the development of U.S. Space Based Infrared System (SBIRS) missile warning satellites, according to a July 23 TASC press release.

TASC unseated incumbent Scitor Corp. of Herndon, Va., to win the SBIRS systems engineering and integration contract, which features a three-year base period with two one-year options, TASC spokeswoman Christine Bragale said. TASC will perform SBIRS systems engineering work that includes architecture development, and verification and validation, the press release said.

TASC was part of Northrop Grumman Corp. until it was sold off last year for $1.65 billion as a result of new federal legislation that made it more difficult for firms to both sell hardware to the government and provide advisory services. TASC became an independent company Dec. 18, four days before it submitted its final bid for the contract, Bragale said.

TASC’s partners on the contract include Northrop Grumman Corp., SAIC, QinetiQ, Alliant Techsystems, Teledyne Brown, AT&T, TriSept, Greendart, Ryan and Beocore, the release said.
