The US Air Force’s 416th Flight Test Squadron recently completed a series of tests of the service’s Gray Wolf prototype cruise missile at Edwards Air Force Base, California.
The Air Force Research Laboratory’s Gray Wolf is a DoD-directed prototype production and demonstration of low-cost, subsonic and networked collaborative cruise missiles. The missiles are designed to launch in a swarm to target enemy integrated air defense threats.
“Gray Wolf is a science & technology demonstration effort, intended as a proof of concept program,” said Conor Most, 416th FLTS Flight Test Engineer. “AFRL serves as the system program office (SPO) for the weapon and developed the original request for proposal.”
The missiles offer a stand-off solution for the warfighter through its variable payload capability. Earlier this year, the Gray Wolf’s TDI-J85 engine completed a successful flight test campaign culminating in multiple inflight windmill starts and operation at high altitude.
The program has already reached certain test milestones: Electromagnetic Interference & Compatibility (EMIC) and a “captive carry” flight. A live release test at the Naval Air Station Point Mugu Sea Test Range is scheduled later this summer.
“The EMIC check is ground check to confirm the missile is okay to fly on our specific test aircraft,” Most explained. “A captive-carry flight is the first flight with the weapon; the goal is to rehearse the weapon flight profile and gather critical state/environmental data about the weapon.”
Most added that the importance of successfully conducting physical tests, as opposed to laboratory-simulated, provides the Gray Wolf team with invaluable critical data.
“Getting the weapon airborne and gathering data is crucial to the development for a new weapon system like this,” Most said. “With just one captive carry flight, the team learned more than in weeks or months of laboratory testing. Modeling and simulation go a long way to helping you predict how a new weapon will behave, but they will never replace actually putting the weapon on an aircraft and observing how it actually behaves in a real-world environment.”
