The Department of Defense awarded Raytheon (NYSE:RTN) two contracts on Monday worth a combined $48.2 million.

In the larger of the two awards, Raytheon's Company Network Centric Systems unit will receive $34 million as a contract modification funding continued development and testing of engineering development models for air and ground fixed and transportable "command post terminals" for the Presidential and National Voice Conferencing (PNVC ) communications system. PNVC is "a satellite-based, worldwide, survivable, secure, and near toll-quality voice conferencing capability for the President, Secretary of Defense, Chairman, Joint Chiefs of Staff, and other senior national/military leaders." Work on this contract should be completed by October 2013.

Raytheon's smaller award gives its Integrated Defense System unit a $14.2 million cost-plus-fixed-fee delivery order to upgrade the Navy's AN/AQS-20A mine hunting sonar with high-frequency, wide-band, forward-looking sonar and multi-function side-looking sonar and associated components. Raytheon will work on this contract through September 2014.
