Vertical Aerospace has announced that is has selected Spanish firm Aciturri to manufacture the airframe for the VX4 eVTOL aircraft.
The agreement, which was announced on August 4, 2025, covers the production of the entire airframe, including the wing, empennage, pylons, and fuselage, and will extend past the certification stage, when Vertical Aerospace plans to serially produce the VX4. Aciturri will also take responsibility for the design and engineering of several of the related key components.
Based in Miranda de Ebro, in central-northern Spain, Aciturri produces aerostructures for some of the world’s largest aircraft manufacturers and has been a supplier to successful aircraft programs, such as the Airbus A320, Boeing 737 airliners and Embraer KC-390 military transport aircraft. In 2024, Aciturri came under the umbrella of the Belgian group Sonaca, which acquired 51% of its shares.
Bit by bit, Vertical Aerospace is defining its network of Tier 1 suppliers for key elements of the VX4 eVTOL. In May 2025, the British company confirmed its partnership with aerospace technology giant Honeywell to develop the avionics and flight control systems for the VX4.
In the meantime, Vertical Aerospace is hitting several key milestones. In May 2025, an VX4 prototype flew for the first time in open airspace, and in July 2025 it completed the first flight between two airports, when it left Cotswold Airport (GBA) to take part in the Royal International Air Tattoo (RIAT) 2025, which took place at RAF Fairford in Gloucestershire.
