The Lockheed Martin-led national team responsible for the maintaining and upgrading the command and control system for U.S. missile defense capabilities has selected Analytical Graphics Inc. (AGI) to provide software to be used for training purposes, AGI of Exton, Pa., said Dec. 3.

AGI’s flagship software product line, dubbed STK, models satellite orbits and trajectories for government and commercial customers. STK can be used to model missile defense scenarios, simulating threat missiles, interceptors and sensors, according to AGI’s website.

The U.S. Missile Defense Agency early this year selected Lockheed Martin of Bethesda, Md., for a contract worth about $980 million to continue work on the command, control, battle management and communications architecture for missile defense. Lockheed Martin’s partners on the system, the integration and nerve center for U.S. missile defense capabilities, include Boeing, General Dynamics, Northrop Grumman and Raytheon.

“The integration and global synchronization of missile defense systems will critically advance our nation’s missile defense capabilities,” AGI Chief Executive Paul Graziani said in a prepared statement.
