Houston-based Lockheed Martin Services has unseated incumbent Jacobs Technology Inc. of Tullahoma, Tenn., to win a NASA contract worth $95.7 million to manage test operations at Stennis Space Center, the agency’s sprawling rocket testing facility near Bay St. Louis, Miss.

The Test Operations Contract that NASA announced Nov. 16 is a cost-plus-award-fee contract with a five-year period of performance consisting of a 30-month base period and one 30-month option period.

As the test operations contractor, Lockheed Martin will be responsible for providing test operations, core operations and maintenance activities at Stennis, NASA said.

Jacobs Technology in May 2003 beat Lockheed Martin and four other bidders to win a six-year Test Operations Contract valued at $126 million. After the U.S. Government Accountability Office upheld a protest filed by two of the bidders, NASA suspended the contract and re-evaluated offers before again selecting Jacobs Technology.

Stennis spokesman Rebecca Strecker said in a Nov. 17 e-mail that Jacobs Technology “retains full operational responsibility for all aspects of the current [Test Operations Contract] through March 31, 2011.” The contract will begin to transition to Lockheed Martin in February, she said.
