US Air Force F-22s and F-35s will soon launch and control recoverable attack drones from the cockpit of the plane to expand air-combat operations, test enemy air defenses, conduct long-range ISR, and even deliver weapons.
This fast-approaching technology, which calls upon advanced levels of autonomous navigation, is closer to reality due of DARPA's Gremlins program which plans to break new ground by launching — and recovering — four drones from an in-flight C-130 in 2019.
Air recoverable drones, slated to become operational over just the next few years, will bring a new phase of mission options enabling longer ranges, improved sensor payloads, advanced weapons, and active command and control from the air.
"The team looked at how fifth generation aircraft systems like the F-35 and F-22 respond to threats, and how they could incorporate Gremlins in higher risk areas," a DARPA statement said.
For years, it has been possible to launch expendable drones from the air, without needing a ground control station, provided they do not return to an aircraft. Gremlins, by contrast, is a technical effort to engineer specially configured aerial drones able to both launch and return to a host aircraft.
The program is now moving into a phase three, according to DARPA statements, which cite a new demonstration and development deal with Dynetics to execute the upcoming launch and recovery C-130 flight.

"DARPA is progressing toward its plan to demonstrate airborne launch and recovery of multiple unmanned aerial systems, targeted for late 2019. Now in its third and final phase, the goal for the Gremlins program is to develop a full-scale technology demonstration featuring the air recovery of multiple low-cost, reusable UASs, or "Gremlins," a DARPA announcement said in early 2018
This technology, which hinges upon higher levels of autonomous navigation, brings a wide swath of improved mission possibilities. These include much longer attack and mission reach, because drones can begin missions while in the air much closer to an objective, without having to travel longer distances from a ground location or forward operating base. Furthermore, perhaps of even greater significance, air-launched returnable drones can be equipped with more advanced sensor payloads able to conduct ISR or even attack missions.
A flight test at Yuma Proving Ground in early 2018 provided an opportunity to conduct safe separation and captive flight tests of the hard dock and recovery system.
"Early flight tests have given us confidence we can meet our objective to recover four gremlins in 30 minutes," Scott Wierzbanowski, program manager in DARPA's Tactical Technology Office, said in a written statement in early 2018.
Gremlins also can incorporate several types of sensors up to 150 pounds, DARPA statements said.
Maturing a full-scale operational capability for this technology has force engineers to confront a range of technical challenges, Dynetics engineers told Warrior Maven. Safely docking a returning drone aboard a moving C-130 requires an as-of-yet unprecedented level of technical sophistication.
"The key technological advance is achieving increased safety through software redundancies to be able to operate a vehicle of this size in close proximity to a C-130 and tether it to stabilize the vehicle," Tim Keeter, Deputy Program Manager and Chief Engineer, Gremlins, Dynetics, told Warrior Maven in a 2018 interview.
Once stabilized, the drone can then be stowed safety in the cargo bay of the C-130, Keeter added.
"This certainly involves precision navigation and we need the structure of the airframe to bear the burden," he said.
In preparation for the upcoming drone air-recovery demonstration, Dynetics conducted a safe separation flight test from a mock air vehicle.
"We are ready to fabricate," Keeter said.
