Anduril Unveils ‘Thunder’: An Autonomous Loyal Wingman to Fly With the Apache
Anduril used the Farnborough International Airshow to roll out an armed unmanned aircraft designed to fly beside attack helicopters. Called ‘Thunder,’ the tiltrotor promises to triple the munitions a formation can bring to the fight without tripling the crews at risk.
At a Glance
- What: ‘Thunder,’ a joint Anduril + Archer Aviation autonomous tiltrotor
- Class: Group 5 hybrid-electric, vertical take-off and landing (VTOL)
- Role: Armed loyal wingman for the AH-64 Apache and the future Bell MV-75
- Where: Farnborough International Airshow 2026
- First flight: targeted for 2027
Defense-technology firm Anduril has pulled the wraps off Thunder, an autonomous, armed aircraft it developed together with electric air-taxi maker Archer Aviation. Anduril frames the machine as a loyal wingman for the rotary-wing world — an uncrewed platform that flies alongside crewed attack helicopters and shoulders the most exposed part of the mission.
Two technologies sit at its core. Archer’s series hybrid-electric powertrain and the Optimum Speed Tiltrotor (OSTR) technology licensed from Karem Aircraft let Thunder lift off vertically like a helicopter yet keep pace with faster platforms such as the Apache thanks to its tilting rotors. Anduril supplies the mission systems and autonomy software.
More Firepower, Same Crew Risk
The concept rests on a simple sum. By the company’s own example, three Thunders flying with a single Apache triple the munitions delivered to the target without tripling the number of crews that have to get there. The crewed helicopter can hold back while the uncrewed aircraft absorb the riskiest leg. As the war in Ukraine has shown, expensive crewed platforms flying low are increasingly vulnerable to man-portable air defenses; Thunder aims squarely at that gap.
Anduril is targeting a first flight in 2027. The company lists Bell’s MV-75 — the rotorcraft emerging from the U.S. Army’s Long-Range Assault Aircraft (FLRAA) program — among Thunder’s likely future ‘lead’ platforms.

The Loyal-Wingman Race Jumps to Rotorcraft
Until now, the loyal-wingman idea has mostly meant jet-powered drones flying with fighters — the U.S. CCA effort, Australia’s MQ-28 Ghost Bat. Thunder is one of the first serious attempts to carry that doctrine into the attack-helicopter world, adapting manned-unmanned teaming (MUM-T) to rotary-wing operations.
Türkiye is advancing quickly on the fixed-wing side of the same doctrine: Baykar’s KIZILELMA and the ANKA-3 are positioned as uncrewed combat platforms to accompany the KAAN next-generation fighter. On the rotary side, the entry of the T929 ATAK-2 heavy attack helicopter into service makes similar manned-unmanned teaming scenarios a natural next chapter for the Turkish defense industry.
