WASHINGTON —The U.S. Air Force's light-attack experiment is set to get a lot bigger, with the service considering adding drones, helicopters and more sophisticated aircraft to the mix in the future, the service's top general told Defense News.
“What is the right mix of fixed wing, rotary wing, manned and unmanned that can do the business of light attack?” Goldfein said in an exclusive Jan. 26 interview. “What is the right mix and how do we bring allies and partners in right now with us — not just periodically parachute in — but how do we expand this experiment to bring them into the tent with us?”
While the Air Force is still finalizing its strategy on light attack, Goldfein's comments hint that a lack of interest by partner nations may have shaped the decision not to press aheadwith a program of record late last year.
The Air Force was set to issue a request for proposals in December for a light-attack platform. The competition would been open to only the Embraer-Sierra Nevada Corp. A-29 Super Tucano and the Textron AT-6 Wolverine, two fixed-wing turboprops that the service said were best suited to meet the needs of the program.
But now, other aircraft could be joining them.
Goldfein said the Air Force chose not to release that RFP for two reasons: ongoing budget uncertainty and the desire to expand the parameters of what the service is seeking.
“For us to issue an RFP when we didn't [know] what the budget was ... and setting an expectation that we're ready to go into source selection when we're still working our way through the strategy, in my mind, would have been irresponsible," Goldfein said. “I've talked to both of the CEOs involved, and we want to make sure we strengthen the partnership and build it as we go forward.”
Goldfein added that light attack was not something that was central to what the Air Force needed, saying that it would only be funded if the money is available in upcoming budgets.
Increasing interoperability has been a longtime goal of the light-attack experiments, but it appears to have taken on new importance as the experiment potentially moves forward.
Goldfein and other Air Force officials have spoken at length about the potential benefit of a common, off-the-shelf attack aircraft that could be purchased by countries that can't afford the F-16, but still want to deepen ties with the U.S Air Force. Over the course of the effort, foreign delegations have been invited to observe flight demonstrations of the A-29, AT-6 and other previous contenders at Holloman Air Force Base, New Mexico.
However, not all nations could want a turboprop aircraft like the A-29 or AT-6.
“Some countries, it actually would be better to have an unmanned option. Some countries, [it] would be better to have a rotary-wing option," Goldfein said. “Some countries would do fixed wing, but [only with a] turbojet [engine]" instead of a turboprop.

By Graham Warwick DARPA has formally launched a program to build and fly an X-plane designed around active flow control (AFC), potentially eliminating the need for moving control surfaces. Designing from the ground up around AFC, rather than modifying an existing aircraft, is expected to yield performance and operational benefits. A broad agency announcement (BAA) was released on Aug. 12 for the first two of four planned phases of the Control of Revolutionary Aircraft with Novel Effectors (Crane) program. A proposers' day is scheduled for Aug. 26 and proposals are due to be submitted by Nov. 8. A budget of $21 million is available for multiple awards under the 12-month Phase 0, which will focus on the aircraft design process and understanding the trade space. DARPA expects performers to enter this phase with multiple candidate configurations and flow-control approaches. Each Phase 0 contract will end with a conceptual design review for one or more configurations. Phase 1 will continue to mature up to two concepts and is expected to involve component-level testing and demonstrations to inform a system requirements review. This nine-month phase is planned to culminate in a preliminary design review for the proposed X-plane. DARPA plans to downselect to one performer at the end of Phase 1 in second-quarter fiscal 2022 and award a contract for Phase 2 detailed design. This is planned to conclude in a critical design review and lead to a go/no-go decision in the second quarter fiscal of 2023 for Phase 3 building and flying of the X-plane. First flight is planned for the third quarter of fiscal 2024. DARPA wants a “tactically relevant scale aircraft,” the BAA says. This may include a “clean-sheet design or modification of an existing aircraft.” The agency expects substantial use of off-the-shelf components for the flight demonstrator so that program resources can be focused on AFC development and testing. AFC modifies the flow field around the aircraft using mechanical or fluidic actuators. The BAA specifically excludes using large external moving surfaces, mechanical vectoring of engine exhaust or other traditional moving aerodynamic control surfaces. AFC applications identified in the BAA include eliminating moving control surfaces for stability and control and improving takeoff and landing performance, high-lift flight, thick-airfoil efficiency and high-altitude flight. Proposers may identify additional applications and benefits. A NATO technical study involving Lockheed Martin, BAE Systems and academic institutes in the U.S. and UK identified that an unmanned combat aircraft with AFC could have stealth and other potential performance benefits during the ingress and egress phases of a strike mission. https://aviationweek.com/defense/darpa-invites-proposals-active-flow-control-x-plane
