The U.S. Department of Defense announced 14 new contracts Thursday, worth more than $640 million, potentially. By far the largest of these awards was a construction contract being split among six smallish construction companies, but the second largest contract went directly to the nation's biggest defense contractor: Boeing (NYSE:BA).

According to the Pentagon, Boeing is being awarded a "modification" of an existing firm-fixed-price, option-filled, foreign military sales (FMS) contract to supply Block III Apache AH-64D attack helicopters to the Taiwanese military.

Valued at $92.3 million, this contract modification lifts the size of the underlying Apache contract past $716 million in total value.
