"The Cobra Dane radar system is a key platform supporting the Air Force and Missile Defense Agency and Raytheon's operational support and sustainment engineering have been instrumental in meeting the customer's missions," said RTSC President John Harris.
"Cobra Dane was introduced in 1977 and the upgraded hardware and software, which we support, have extended the system's operational life by more than 15 years."
The AN/FPS-108 Cobra Dane was originally built by Raytheon and modernized by Raytheon Integrated Defense Systems.
