The Dynetics X-61 Gremlins is an experimental unmanned aerial vehicle designed by Dynetics.
The X-61 stemmed from the DARPA Gremlins program to demonstrate a recoverable, low-cost UAV with digital flight controls and navigation systems. It is designed to be recovered in midair by a modified transport airplane following its mission. [1] Dynetics was one of four companies to be awarded a Phase I contract for the program in 2016, and was the winner of the Phase III contract in April 2018. [1]
The X-61A is powered by a Williams F107 turbofan engine and can carry a variety of payloads, including electro-optical sensors, infrared imagers, electronic warfare systems, and weapons. [1] [2] It was designed to be compatible with existing launch and ground support equipment. [1] The UAV is semi-autonomous, allowing a controller either in the mothership or on the ground to control up to eight X-61As at one time. [1] [2]
As of January 2020, five X-61A Gremlins have been built. [3] On July 5, 2019, an earthquake near China Lake damaged some of the first X-61A's test equipment, delaying the program. [2] The first captive flight of the X-61A on board a Lockheed C-130A Hercules mother ship was in November 2019. [1]
The first free flight of the X-61A was conducted on January 17, 2020. The flight was successful, however, the main parachute failed to deploy during the recovery and the aircraft was lost. [4] The four remaining vehicles are still operational. [5]
In August 2020 the company announced they had completed a second test flight, this time successfully recovering the aircraft by parachute. The flight lasted over two hours and included rendezvous and formation flight with the C-130 mother ship. [6]
In October 2021 DARPA announced that a specially equipped C-130 Hercules cargo plane had successfully recovered an X-61A from mid-air. [7]

The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements. The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996.
The Boeing X-45 unmanned combat air vehicle is a concept demonstrator for a "next generation" of completely autonomous military aircraft, developed by Boeing's Phantom Works. Manufactured by Boeing Integrated Defense Systems, the X-45 was a part of DARPA's J-UCAS project.
The Northrop Grumman X-47 is a demonstration unmanned combat aerial vehicle. The X-47 began as part of DARPA's J-UCAS program, and is now part of the United States Navy's UCAS-D program to create a carrier-based unmanned aircraft. Unlike the Boeing X-45, initial Pegasus development was company-funded. The original vehicle carries the designation X-47A Pegasus, while the follow-on naval version is designated X-47B.
Mid-air retrieval is a technique used in atmospheric reentry when the reentering vehicle is incapable of a satisfactory unassisted landing. The vehicle is slowed by means of parachutes, and then a specially-equipped aircraft matches the vehicle's trajectory and catches it in mid-air.
The Williams F107 is a small turbofan engine made by Williams International. The F107 was designed to propel cruise missiles. It has been used as the powerplant for the AGM-86 ALCM, and BGM-109 Tomahawk, as well as the experimental Kaman KSA-100 SAVER and Williams X-Jet flying platform.
The Boeing X-50A Dragonfly, formerly known as the Canard Rotor/Wing Demonstrator, was a VTOL rotor wing experimental unmanned aerial vehicle that was developed by Boeing and DARPA to demonstrate the principle that a helicopter's rotor could be stopped in flight and act as a fixed wing, enabling it to transition between fixed-wing and rotary-wing flight.
An airborne aircraft carrier is a type of mother ship aircraft which can carry, launch, retrieve and support other smaller parasite aircraft. The only dedicated examples to have been built were airships, although existing heavier-than-air aircraft have been modified for use in similar roles.
The Boeing A160 Hummingbird is an unmanned aerial vehicle (UAV) helicopter. Its design incorporates many new technologies never before used in helicopters, allowing for greater endurance and altitude than any helicopter currently in operation.
The Northrop Grumman X-47B is a demonstration unmanned combat aerial vehicle (UCAV) designed for aircraft carrier-based operations. Developed by the American defense technology company Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and subsequently became part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refueling.
The BAE Systems Taranis is a British demonstrator programme for unmanned combat aerial vehicle (UCAV) technology, under development primarily by the defence contractor BAE Systems Military Air & Information. The aircraft, which is named after the Celtic god of thunder Taranis, first flew in 2013. An unmanned warplane, the Taranis is designed to fly intercontinental missions, and would carry a variety of weapons, enabling it to attack both aerial and ground targets. It uses stealth technology, giving it a low radar profile, and is controllable via satellite link from anywhere on Earth.
The DRDO Nishant - is an unmanned aerial vehicle (UAV) developed by India's Aeronautical Development Establishment (ADE), a branch of Defence Research and Development Organisation (DRDO) for the Indian Armed Forces. The Nishant UAV is primarily tasked with intelligence gathering over enemy territory and also for reconnaissance, training, surveillance, target designation, artillery fire correction, damage assessment, ELINT and SIGINT. The UAV has an endurance of four hours and thirty minutes. Nishant has completed development phase and user trials. However, further development of the project was cancelled after all of the four prototypes and production UAVs crashed due to various and unknown reasons.
