Raytheon [RTN] Wednesday said it was awarded a $43 million contract modification by the Missile Defense Agency (MDA) to continue developing the common X-Band capability software and modeling and simulation capabilities for the TPY-2 radar.

“As global threats continue to evolve, it is critical that we continue to deliver affordable and reliable solutions that defend our homeland, our warfighter and our allies,” Dave Gulla, vice president, National & Theater Security Programs for Raytheon Integrated Defense Systems, said in a statement.

Raytheon’s TPY-2 radar provides a common mission capability: in terminal-based mode with the THAAD Fire Control Center in support of the THAAD weapon system, and in a forward- based mode with command, control, battle management and communications, enabling MDA’s Ballistic Missile Defense System.

It is a phased array, capable of search, threat detection, classification, discrimination and precision tracking at extremely long ranges.

“As an integral component in MDA’s Ballistic Missile Defense System, the AN/TPY-2 radar is one of the critical systems that our warfighters rely on to respond to incoming ballistic missile defense threats,” Gulla added.

Work on this contract will be performed at Raytheon’s Missile Defense Center, Woburn, Mass., and at Raytheon’s Warfighter Protection Center, Huntsville, Ala.
