The US Air Force’s newest combat rescue helicopter was suspended in a soundproof chamber at the Joint Preflight Integration of Munitions and Electronic Systems facility in mid-November for defense system testing.

The US Air Force 413th Flight Test Squadron’s HH-60W spent approximately seven weeks testing the defensive systems upgrades from the legacy HH-60G currently flown by Air Combat Command.

“The J-PRIMES facility has the unique capability to capture high quality data on defensive systems by isolating the electromagnetic radiation inside the facility’s anechoic chamber. The chamber is a room designed to stop reflections of sound or electromagnetic waves and is insulated from external noise. Testing the HH-60W in J-PRIMES will characterize the performance of the helicopter’s systems before electronic warfare flight-testing. The tests ensure it is capable of defeating hostile threats while performing its designated combat search and rescue mission.”

The new aircraft arrived at the 96th Test Wing in early November.

The US Air Force is contracted to purchase 113 HH-60W aircraft to replace its aging fleet of HH-60G helicopters.

According to the US Air Force:

“The J-PRIMES facility hosts similar test missions throughout the year. The facility provides an environment to facilitate testing air-to-air and air-to-surface munitions and electronics systems on full-scale aircraft and land vehicles before open air testing. The J-PRIMES test data will be used to support specification compliance and check for defensive system discrepancies or concerns.”

This is an early, but critical step in the developmental process of the new HH-60W. After J-PRIMES testing, this particular aircraft will begin flight tests for its defensive systems.

Cool huh. Do we have anything like that capability? Not something I’ve ever heard of or is it done by the manufacturer ?
