Open in interactive gallery →See aircraft like this on the live radar →

The General Atomics MQ-20 Avenger, originally designated Predator C, is a jet-powered, low-observable, single-seat unmanned combat air vehicle (UCAV) developed by General Atomics Aeronautical Systems (GA-ASI). Conceived as a private-venture next-generation UCAV, it was designed to fly in higher-threat air-defence environments than the propeller-driven MQ-9 Reaper. First flight occurred in April 2009. GA-ASI has continued to develop the type as a private venture, with limited U.S. Air Force deployment for classified missions and continuing customer interest. By 2026, between seven and ten airframes had been built or modified across several block standards.

Configured as a tailless lambda-wing low-observable airframe, the MQ-20 measures 41 ft (12.5 m) long with a 66 ft (20.1 m) wingspan. Empty weight sits around 8,000 lb against a maximum take-off weight of 18,000 lb. Power comes from a single Pratt & Whitney Canada PW545B turbofan rated at roughly 4,800 lbf thrust, giving a maximum speed of about 460 mph (Mach 0.7), service ceiling of 50,000 ft, unrefuelled range of 2,900 nmi, and mission endurance beyond 18 hours. Radar cross-section is much lower than the MQ-9 Reaper's, improving survivability against integrated air-defence systems. An internal weapons bay holds roughly 6,500 lb for stealth profiles, while external hardpoints add up to 3,000 lb when low observability is not required.

Design philosophy diverges sharply from the MQ-9. The Reaper is tuned for permissive airspace — long endurance, large weapons load, propeller propulsion for fuel economy. The Avenger trades endurance (18 hours against the MQ-9's 27) for survivability: jet propulsion for higher altitude and faster transit, low-observable shaping, and an internal bay for stealth approach. That trade reflects the changed threat environment of the 2010s and 2020s. A typical mission profile penetrates enemy air defences at 50,000 ft above most ground-based SAM threats, conducts ISR or strike, then exits at high speed.

Public deployment has been limited. GA-ASI uses the platform mainly for development testing of new technologies — including AI and autonomy software — and for ongoing customer demonstrations. Known activity includes U.S. Air Force use of the MQ-20 'Avenger Extended Range' for classified missions, AI-based autonomous flight control demonstrations, and NATO and allied evaluations. The MQ-20 has become a key research platform for AI autonomy: General Atomics has partnered with the U.S. Air Force Research Laboratory and DARPA on multiple demonstration programmes flown on the type. As of 2026 it has not entered series production for any single customer but continues to be refined as GA-ASI's primary development airframe. Lessons learned have fed directly into the General Atomics YFQ-42A Dark Merlin, the U.S. Air Force's selected Increment 1 Collaborative Combat Aircraft.

For Kids — a shorter, friendlier version

The General Atomics MQ-20 Avenger (also called the Predator C) is an American jet-powered stealth combat drone. The MQ-20 first flew in April 2009. Unlike the propeller-powered MQ-9 Reaper, the Avenger has a jet engine for higher speed and altitude. About 7 to 10 have been built so far.

The MQ-20 is 41 feet long with a 66-foot wingspan, longer than a school bus. One Pratt and Whitney Canada PW545B jet engine makes 4,800 pounds of thrust. Top speed is around 460 mph, faster than most race cars. The drone can climb to 50,000 feet and stay airborne for 18 hours.

The Avenger has a tailless lambda-wing shape, smooth and stealthy like the X-47B. An internal weapons bay holds 6,500 pounds of bombs and missiles, hidden from enemy radar. The drone also has external hardpoints when stealth is not needed, adding 3,000 pounds more weapons.

The MQ-20 was built as a private project by General Atomics, not paid for by the Air Force at first. A few MQ-20s have been used by the Air Force for secret missions and as test planes for new artificial intelligence software. The MQ-20 helps shape the future of unmanned combat planes.

Kids’ Questions

How is it different from the Reaper?

The MQ-9 Reaper has a propeller and is slower; the MQ-20 has a jet engine and is much faster. The Reaper is built for long missions in safe airspace; the Avenger is built to slip into dangerous airspace with stealth. The Avenger flies higher and stays airborne 18 hours, less than the Reaper's 27 hours but much more survivable against enemy defenses.

Why a private project?

General Atomics paid for the MQ-20 with its own money, hoping the Air Force would buy a lot. The Air Force did not order many in the end, but bought a few for secret missions. The MQ-20 also became a test plane for new artificial intelligence software. Building it privately let General Atomics try new ideas faster.

What is a lambda wing?

A lambda wing is shaped like the Greek letter, pointed forward and angled back at the edges. The shape is very stealthy because it scatters radar beams in many directions. The MQ-20, X-47B, and other modern combat drones all use the lambda wing shape. The B-21 Raider bomber uses a similar design.

Variants

MQ-20 Avenger / Predator C (initial)
Original 2009 development variant; first flight April 2009. Three to four prototypes built for GA-ASI development testing, used for flight test programmes and customer demonstrations.
MQ-20 Avenger Extended Range (Block 2)
Improved variant from around 2014 with a 66 ft wing (versus the original 50 ft), increased fuel, and extended endurance. Roughly three built. Used for U.S. Air Force deployments (specific operations classified) and ongoing development testing.
Avenger ER 'Predator C' (further development)
Further development variant from around 2016 with improved sensors, expanded weapons compatibility, and enhanced autonomy. Limited number built; used for ongoing test programmes and customer demonstrations.
MQ-20-derived YFQ-42A Dark Merlin (CCA)
Direct successor. The General Atomics YFQ-42A was selected in April 2024 as one of two U.S. Air Force Increment 1 Collaborative Combat Aircraft platforms. It draws heavily on MQ-20 lineage with U.S. Air Force-specific modifications. Initial fielding is targeted for the late 2020s. See the separate YFQ-42 entry.
Joint X-NN demonstrators (related)
GA-ASI test platforms derived from MQ-20 lineage, including X-NN demonstrators for AI and autonomy development. Multiple AI-autonomy demonstration flights have been conducted by AFRL, DARPA, and GA-ASI on MQ-20 / X-NN platforms, feeding into broader U.S. Air Force CCA programme development.

Notable Operators

General Atomics Aeronautical Systems (developer / operator)
Sole owner and operator. GA-ASI flies five to seven Avenger variants for development testing, AI-autonomy research, and customer demonstrations from Gray Butte Field Airport, California, and other GA-ASI test facilities. Limited U.S. Air Force deployment for classified missions is conducted through joint-deployment arrangements.
U.S. Air Force (classified deployments)
Limited frontline use of the MQ-20 'Avenger ER' for classified missions; specific operations are not publicly disclosed. Acknowledged use includes development testing and AI-autonomy demonstrations. The U.S. Air Force has not committed to MQ-20 series production — the platform's role has been principally a development bridge to the YFQ-42A CCA.
Foreign / export evaluations
Allied nations that have evaluated the MQ-20 include the United Kingdom (Royal Air Force evaluation in 2014), Germany (limited evaluation), and India (under negotiation as part of broader India–U.S. defence cooperation). No formal export procurement has been completed, though several countries continue to evaluate the platform and its derivatives.
AFRL / DARPA / U.S. Air Force test partnership
Major user of the MQ-20 for AI and autonomy development. The AFRL Skyborg programme (2019–2022) used the type for AI-pilot demonstrations, and DARPA's Air Combat Evolution (ACE) programme used it for AI dogfighting demonstrations. Research output from these programmes has informed broader U.S. Air Force CCA development.

Frequently Asked Questions

How does the MQ-20 differ from the MQ-9 Reaper?

The two aircraft reflect different design philosophies. The MQ-9 Reaper uses turboprop propulsion, cruises at 230 mph, reaches a 50,000 ft service ceiling, endures 27 hours, carries a large external weapons load, and is not low-observable. The MQ-20 Avenger is jet-powered with a 460 mph maximum speed, the same 50,000 ft ceiling, 18-hour endurance, an internal weapons bay, and low-observable shaping. The MQ-9 is tuned for permissive air-defence environments and the MQ-20 for contested ones. In service the two are complementary rather than competing.

What is the YFQ-42A Dark Merlin?

It is the U.S. Air Force's Collaborative Combat Aircraft (CCA) Increment 1 platform, selected in April 2024. The YFQ-42A is drawn directly from MQ-20 lineage — General Atomics' winning entry was based on Avenger family heritage. The CCA programme aims to acquire more than 1,000 unmanned 'wingmen' to fly alongside crewed fighters such as the F-35, F-22, and NGAD. The YFQ-42A is one of two selected platforms; the Boeing YFQ-44A is the other. Initial fielding is targeted for the late 2020s. The YFQ-42A's direct descent from the MQ-20 shows how 15+ years of Avenger development paid off in the CCA selection.

How many MQ-20 have been built?

Between seven and ten airframes across multiple block standards — a modest run reflecting the platform's role as a private-venture demonstrator rather than a series-production frontline aircraft. The fleet comprises the original 2009 MQ-20 prototype, three to four production-representative test airframes, and three Avenger ER variants. Exact counts are not publicly disclosed; some airframes are presumed lost in deployments or development testing. The low production volume reflects the development focus — series production was always intended to follow customer commitments rather than private-venture funding.

Has the MQ-20 been used in combat?

Combat use has been limited and largely unreported. U.S. Air Force deployments of the MQ-20 'Avenger ER' for classified missions are not publicly disclosed. Deployments to U.S. Central Command (CENTCOM) areas of operations have been reported, but mission details, success and loss data, and concept of employment remain classified. The MQ-20's principal role has been development-focused, with combat deployment secondary. Lessons learned from any frontline use have been incorporated into the YFQ-42A CCA design.

How does the MQ-20 compare to the X-47B Pegasus?

The two aircraft serve different mission concepts. The Northrop Grumman X-47B demonstrator first flew in 2011 and was designed for U.S. Navy carrier-based UCAV operations; it performed the first carrier-based unmanned aircraft launch and recovery in 2013, and the programme was cancelled in 2015. The General Atomics MQ-20 Avenger demonstrator first flew in 2009 and was designed for U.S. Air Force land-based UCAV operations; development continued through to 2026 and informed the YFQ-42A CCA platform. Both are tailless lambda-wing low-observable designs aimed at different mission domains. Both contributed lessons learned to follow-on platforms — the X-47B to the MQ-25 Stingray and the MQ-20 to the YFQ-42A.

What does the MQ-20 cost?

Specific cost data is not publicly disclosed. General Atomics has invested an estimated $200-400M USD of company funds over the 17-year-plus programme. Per-airframe cost estimates run between $30M and $50M USD inclusive of mission systems and flight test instrumentation. The high per-airframe cost reflects the development-focused nature of the platform; series production would lower unit cost through volume amortisation. The follow-on YFQ-42A targets a $25-35M USD per-airframe production cost, drawing on series-production economies and lessons learned from MQ-20 development.
