Just a day after awarding it a pair of contracts worth up to $174.2 million Thursday, the Department of Defense came back and awarded local defense contractor Science Applications International Corp (NYSE: SAI) two more contracts Friday

The larger of the two awards, for $99.5 million, came in the form of an indefinite-delivery/indefinite-quantity (IDIQ) contract to work on the Defense Threat Reduction Agency's Cooperative Threat Reduction (CTR) project to control nuclear proliferation. SAIC will provide logistics support to CTR through June 2016.

The smaller award, for $15 million, was made smaller still by the fact that SAIC must share it with a rival firm, Anderson, S.C.'s Advanced Technology International. DoD exercised options to give each firm part of a one-year extension of a contract to conduct field tests and evaluation support services for the Naval Facilities Engineering and Expeditionary Warfare Center, Port Hueneme. Going forward, the two firms will bid against each other to win task orders under the umbrella contract, with total payments between the two firms not to exceed the stated $15 million. This contract extension runs through June 2014.
