The Gremlin initiative was launched by the Defense Advanced Research Projects Agency (DARPA) to improve the capability and cost-efficiency of tiny drones.

According to recent sources, DARPA has reached a significant milestone in evaluating the operational capability of Dynetics’ X-61 Gremlins unmanned aerial systems (UASs).

The capacity of multi-function manned aircraft to undertake a number of essential duties, both combat and non-combat, has been critical to US military operations. Over the last few years, however, opponents’ capacity to detect and destroy these aircraft from afar has advanced substantially.

As a result, the US military is investing heavily in improving aircraft designs and incorporating modern characteristics such as stealth and electronic warfare into them.

The ability to dispatch drone swarms, on the other hand, might provide the US military a lot more operational freedom. These drones would also be cost-effective if they could be launched and recovered in mid-air. DARPA had created the Gremlins programme with this aim in mind.

The Gremlins programme envisions launching swarms of drones from existing large aircraft such as bombers or transport planes, as well as fighters and other small, fixed-wing platforms. It is named after the imaginary, mischievous imps that became the good luck charms of many British pilots during World War II.

At all times, these aircraft will keep out of the enemy’s defences. Once the Gremlins have completed their mission, they will be picked up mid-flight by a Lockheed C-130 Hercules transport plane and returned to the ground, where ground technicians will ready them for their next mission within 24 hours.

DARPA successfully recovered an unmanned X-61 Gremlins air vehicle from a C-130 while it was already in flight for the first time. This achievement was a watershed moment in the US military’s efforts to launch drone swarms from a mothership in mid-flight.

According to a statement made by DARPA on November 5, the successful mid-air recovery of the Gremlins drone took place on October 29 at Dugway Proving Ground in Utah.

According to the announcement, this was the Gremlins’ fourth flight test, which involved two tiny drones. All formation flying positions, as well as all safety precautions, were successfully completed by these drones.

According to DARPA, one of the two Gremlins was successfully retrieved, but the other was destroyed during flight tests. The Gremlins team rebuilt the recovered drone, and it flew again within 24 hours, according to the DARPA statement.

DARPA intends to give the military the capacity to launch these small sensor-laden drones into enemy defences from a large bomber, transport, or fighter aircraft, while the latter remains out of range of the opponent’s defences at all times.

All critical duties, including as intelligence, surveillance, reconnaissance, and electronic warfare, would be carried out by the drones. A video was published by the government showing a Gremlin latching onto a docking bullet deployed from the C-130.
The drone then folded its wings into its body before being snatched up by a recovery arm and carried inside the C-130.

In a 2018 study, DARPA stated, “After the mothership gathers the drones and returns them to base, ground technicians would get them ready for another trip within 24 hours.” Each Gremlin is expected to fly at least 20 times throughout its lifetime, according to the CIA.

Lt. Col. Paul Calhoun, the Gremlins programme manager at DARPA’s Tactical Technology Office, said, “This recovery was the culmination of years of hard effort and demonstrates the capability of safe, reliable airborne recovery.” “Such a capability will very certainly become important for future distributed air operations,” says the author.

Similar attempts at airborne retrieval of these Gremlins had been made in the past, but they had failed miserably. DARPA started a series of flight tests in October 2020, attempting to collect three Gremlins nine times, but all of the attempts were unsuccessful.

Four flights were conducted during the recent test, during which hours of data were collected, including information on air vehicle performance, coordination during the airborne retrieval, and the aerodynamic interactions between the Gremlins and the C-130’s recovery bullet, according to the release.

Calhoun stated in the press release that “airborne recovery is complicated.” “We’ll take a break to celebrate this deployment’s success, then go back to work evaluating the data and considering future steps for the Gremlins technology,” he added.
