AN/CPS-9

The AN/CPS-9 is a type of long-range air search radar system previously used by the United States Air Force (USAF) and potentially other military organizations. Information regarding its precise operational capabilities and technical specifications is often limited due to its military application.

The system likely operated in the L-band frequency range, a common choice for air search radar due to its favorable balance between range and atmospheric attenuation. It would have been designed for early warning and air traffic control, providing data on the location, altitude, and speed of aircraft within its coverage area. Data from the AN/CPS-9 would be fed into command and control systems, allowing for coordinated air defense or air traffic management responses.

The AN/CPS-9 was typically a large, transportable or fixed radar installation, requiring significant logistical support for deployment and maintenance. It likely employed a rotating antenna to scan the airspace in a 360-degree radius. While the exact lifespan of the system is unclear, it would have been subject to upgrades and eventual replacement by newer, more advanced radar technologies. Specific details on its development history, manufacturers, and operational deployments are difficult to ascertain from publicly available sources.
