Air Force Research Laboratory (AFRL) Commander Brig. Gen. Heather Pringle and Air Force program executive officer for aircraft and advanced weapons Brig. Gen. Dale White are leading an effort this year to test multiple prototypes for Skyborg, one of three Air Force Vanguard programs intended to field advanced capabilities rapidly.
“We have more tests this year,” Pringle said Feb. 4 of Skyborg during a Mitchell Institute for Aerospace Studies’ Aerospace Nation virtual forum. “We have multiple prototypes that we’ll be looking at, and we’re assessing the military utility and capabilities with our warfighter partners. We’re driving toward, Gen. White and I and our whole team, an initial capability in 2023.”
The tests will follow a demonstration on Dec. 9 in which a Skyborg XQ-58A Valkyrie attritable by Kratos [KTOS] flew in formation over U.S. Army Yuma Proving Ground, Ariz., with a Lockheed Martin [LMT] F-22 and an F-35 fighter and served as a gatewayONE communications translator between the two fighters.
Northrop Grumman [NOC] builds gatewayONE, which is to link fourth and fifth generation fighters and attritables as part of the Air Force Advanced Battle Management System (ABMS).
The December demonstration, in which the Valkyrie flew in formation with the F-22 and F-35, was “the first ever opportunity to show an attritable as a force multiplier with two fifth gen aircraft,” Pringle said.
“There were a couple of challenges that we faced,” she said of the December test. “With the attritable itself, it was a rocket-assisted takeoff,” which shook the aircraft and “caused stress on the communication gateway so we weren’t able to establish it in flight with the onboard communication gateway, but we still achieved the objective because we had a backup on the ground so the connections were made, and so we still got the job done.”
The Air Force has said that it expects to receive the first prototypes by May for initial flight tests and to begin experimentation in July.
Skyborg is to develop a family of attritable aircraft systems with a common artificial intelligence (AI) backbone that can train alongside manned aircraft and eventually help complete tasks, fly ahead of Air Force pilots in non-permissive environments, and frustrate adversaries.
AFRL has used Kratos’ XQ-58A Valkyrie as an example of what a Skyborg prototype could look like.
