Government shutdown or no, defense contractor Lockheed Martin (LMT 1.23%) is still raking in the contracts.

On Monday, Lockheed confirmed that it has won a place in an indefinite-delivery/indefinite-quantity contract worth up to $4.1 billion to supply communications and transmission systems to the U.S. Army's Project Manager of Defense Communications and Army Transmissions Systems. Under this contract, Lockheed will compete against other contract recipients for the right to complete "task orders" to supply the Army with satellite and terrestrial communications gear over the next five years.

Commenting on the contract win, Lockheed Martin Information Systems & Global Solutions vice president of Space & Cyber Robert Smith promised to supply the Army with "enhanced situational awareness and network connectivity to the Warfighter -- regardless of location."

Lockheed's partners on this contract will be Globecomm (NASDAQ: GCOM), Inmarsat, and Hughes Network Systems. Conversely, the company and its partners will be bidding for task orders against large rivals such as AT&T (T -1.37%), General Dynamics (GD 1.35%), and L-3 Communications (NYSE: LLL) -- each of which was named as having won a place in this contract in a Department of Defense announcement late last month.
