Raytheon to upgrade missile defense radars

Raytheon has been awarded a Missile Defense Agency contract modification to upgrade missile defense radars.

Under the contract, Raytheon will develop a process to incorporate gallium nitride (GaN) components into existing and future AN/TPY-2 radars, according to a company news release. Current AN/TPY-2 radars use gallium arsenide (GaAs)-based transmit/receive modules to emit high-power radiation.

"GaN components have significant, proven advantages when compared to the previous generation GaAs technology," said Dave Gulla, a vice president at Raytheon. "Through this effort, Raytheon will develop a clear modernization upgrade path for the AN/TPY-2 radar, enabling the system to better defend people and critical assets against ballistic missile threats at home and abroad."
