Lockheed Martin has won a $293 million contract to provide network operations support to the Pentagon and other military networks in the Washington, D.C., area.

Lockheed will manage, operate, and secure the Pentagon's data networks and provide 24 by 7 support to users. According the Army's IT Agency, the Pentagon's network infrastructure includes more than 16,000 miles of wiring and cable.

Lockheed has been providing outsourced IT services to the Pentagon since 2000, when it won a 10-year contract with the Army to renovate the Pentagon's IT infrastructure. In that deal, Lockheed was responsible for providing IT infrastructure and network management "from the wall plate all the way out to the networks."

In March, the Army awarded a six-month extension to bridge the earlier contract with the new one. The new contract runs for one year and includes two one-year options, so it could run through 2014.

Known more for its aerospace arm, Lockheed is one of the Department of Defense's largest IT contractors.
