Anduril Industries and Archer Aviation have unveiled Thunder, a hybrid-electric autonomous attack VTOL aircraft, at the Farnborough International Airshow on July 21. The clean-sheet design combines Archer's eVTOL expertise with Anduril's defense technology, aiming for a first flight in 2027.
The defense variant, dubbed Thunder, is a Group 5 autonomous rotorcraft designed to operate alongside crewed aircraft without a pilot. It uses a series hybrid-electric powertrain with dual tiltrotors, enabling vertical takeoff and landing while reducing acoustic signature and extending range. Archer plans to announce commercial customers for a civilian variant later this week Source: Fox Business.
“It operates on a hybrid-electric powertrain that helps boost the platform's range and endurance, while it also utilizes dual tiltrotors to maintain its efficiency in different flight regimes by lowering power demand and fuel consumption when cruising and minimizing its acoustic signature to increase its survivability when making a low-altitude ingress.”
“Thunder is an autonomous attack aircraft that can carry missiles or rockets, patrol airspace and carry cargo.”
“Thunder differs from Midnight in that it's a series hybrid powertrain, as opposed to a fully electric one. The hybrid system will help the aircraft achieve significantly longer range 'while still maintaining the necessary precision to closely optimize power through the full range of flight conditions,' Archer says.”
Both companies emphasize that Thunder is not a modified air taxi but a purpose-built platform leveraging commercial eVTOL technology for defense. Archer CEO Adam Goldstein stated, 'We couldn't simply tweak our existing aircraft. We took a bold first principles approach' Source: Fox Business.

The announcement contrasts with Vertical Aerospace's separate military interest from the UK Ministry of Defence for its hybrid-electric Valo aircraft, also showcased at Farnborough Source: The Guardian.
“Archer on Monday unveiled its Thunder autonomous vertical takeoff and landing defense craft with Anduril, designed to accompany crewed aircraft and helicopters. The companies first joined forces in 2024.”
