USAF tests AN/APR-52 radar warning receiver for HH-60W CRH


The US Air Force (USAF) has successfully completed testing on Lockheed Martin’s AN/APR-52 radar warning receiver (RWR) for combat rescue helicopter (CRH).

The AN/APR-52 RWR system achieved Technical Readiness Level (TRL) 6 assessment after the USAF demonstrated the platform at its integrated demonstrations and applications laboratory at Wright Patterson Air Force Base in Dayton, Ohio, US.

The all-digital, four-channel radar receiver forms a part of the defensive system's suite that will provide threat detection capability to HH-60W CRH intended to replace HH-60G Pave Hawk helicopters.

Lockheed Martin Electronic Warfare Programs director Bob Adams said: “Although extensive contractor testing was previously conducted on the AN/APR-52 RWR, the USAF laboratory provides a unique capability that allows high-fidelity demonstration of the system in a true operational environment.

“The successful demonstration is a key milestone to ensure the system will meet the needs of the warfighter. The complete electronic warfare suite will significantly improve detection of current and emerging threats, which increases the survivability of the HH-60W.”

A Lockheed Martin company, Sikorsky, will produce 112 HH-60W helicopters as part of a contract awarded by the USAF in 2014.

"The complete electronic warfare suite will significantly improve detection of current and emerging threats, which increases the survivability of the HH-60W."

Sikorsky CRH programme director Tim Healy said: “The APR-52 represents a significant leap in radar warning performance for rotary wing aircraft.”

Lockheed Martin said that AN/APR-52 RWR has been designed to process a large number of signals simultaneously to more quickly and accurately identify threats to the aircrew.

The radar receiver is claimed to provide a high probability of detection for modern and emerging threats in very dense signal environments.

The TRL demonstration follows critical design review of HH-60W helicopter, which was achieved in May.
