The U.S. Department of Defense awarded a total of only eight contracts Tuesday, worth $760 million in total. Textron was the big winner today on dollar value, winning a $641 million contract for the production of cluster bomb munitions. In terms of total contracts won, however, the clear winner was Lockheed Martin (LMT 1.23%), which picked up two contracts, and most of a third.

Lockheed's biggest contract win, and the second biggest contract awarded Tuesday, was a $37.3 million contract modification to add funds to a previously awarded contract funding engineering work on the Aegis air-defense platform. Lockheed will be working on this contract through September 2014.

A smaller award, for $10.1 million, funds the purchase of a single AN/BVY-1 Integrated Submarine Imaging System (ISIS) plus associated spare parts, for the U.S. Navy. ISIS is a visual and digital imaging system that is integrated into submarine periscopes.

Lockheed's final contract victory comes in the form of a firm-fixed-price, no-option, foreign military sales contract modification awarded to the company's Hellfire Systems LLC subsidiary -- now wholly owned by Lockheed Martin. The award calls on Hellfire LLC to produce Hellfire II air-to-ground missiles for the United Arab Emirates. Valued at $8.2 million, Lockheed should collect most, but not all, of the funds allotted. Part of the income from Hellfire missile sales goes to Lockheed's former partner in Hellfire LLC, Boeing, which at last report was still receiving residual "fee-per-missile" payments for missiles sold by the LLC.

In total, the Hellfire contract has now risen past $886 million as a result of today's contract modification.
