Pratt & Whitney on CCA drone

A collaborative combat aircraft is a drone built to fly with a crewed fighter, take some of the risk, and carry sensors or weapons under a pilot’s direction. Pratt & Whitney said on April 17 that one of its PW500 engines is now installed in Northrop Grumman’s YFQ-48A Talon Blue and is ready for flight tests. (rtx.com) The engine is not a clean-sheet military design. Pratt adapted a member of its PW500 commercial engine family, which the company said has logged more than 24.5 million flight hours, for the Air Force drone’s mission profile. (rtx.com) Pratt said it worked with Northrop Grumman on engine requirements and integration, then ran tests to push the PW500 beyond its normal commercial operating limits. The company said those tests simulated flight and operating conditions unique to collaborative combat aircraft missions and produced favorable thrust, range, and operability results. (rtx.com) Northrop’s aircraft entered public view in December 2025, when the Air Force gave Project Talon the YFQ-48A Mission Design Series designation. The service called it a “strong contender” in the Collaborative Combat Aircraft program and said the aircraft is meant to complement manned fighters with semi-autonomous capability. (af.mil) In plain terms, the engine sets the drone’s basic envelope: how far it can fly, how fast it can respond, how much payload it can carry, and how reliably it can complete an autonomous sortie. That is why Pratt’s announcement focused as much on integration and test data as on the engine model itself. (rtx.com) The Air Force’s first two designated collaborative combat aircraft came from General Atomics and Anduril, which received the YFQ-42A and YFQ-44A designations in early 2025. Northrop’s YFQ-48A became the third such designation in December 2025, but it sits outside the original Increment 1 pair and reflects the service’s wider search for lower-cost autonomous escorts. (defensenews.com) Northrop says Talon Blue was reshaped after customer feedback to cut part count and weight while adding mission flexibility and using modular manufacturing methods. Defense News reported in January that Northrop’s earlier bid had performed well but was judged too expensive, pushing the company to rework the design. (northropgrumman.com) (defensenews.com) Pratt had been laying the groundwork for this role since at least September 2025, when it said testing on its small turbofan family showed it could raise thrust for collaborative combat aircraft use. The company also said at the time that the same engine family could support domestic and international customers, suggesting it sees this as a production line, not a one-off integration. (rtx.com 1) (rtx.com 2) The near-term test is simple: whether Talon Blue can turn a commercially derived engine, new control software, and a lower-cost airframe into repeatable flight performance. Pratt says the engine is ready for those flight tests now, which makes propulsion one of the next concrete checkpoints in Northrop’s bid to stay in the Air Force contest. (rtx.com)
