Vertical Aerospace And Syensqo Team Up To Drive VX4 Aircraft Industrialisation

Syensqo’s high-performance composite and adhesive materials already used in Vertical’s prototype programme have been selected for the VX4 aircraft which aims for certification in 2028 ahead of commercial service entry. The announcement follows years of close collaboration between Syensqo and Vertical.

Syensqo’s advanced materials will be used throughout the VX4’s structure, delivering the lightweight strength, durability and structural efficiency needed for high-cycle electric vertical flight operations. Securing these composites is essential to ensure the aircraft can withstand frequent take-offs and landings while maintaining consistent safety and performance.

The VX4 airframe will be manufactured by Aciturri, a leading global aerostructures supplier, supporting Vertical’s transition into full-scale commercial production.

With extensive aerospace expertise and a track record of supplying advanced materials to major aircraft and defence manufacturers worldwide Syensqo is positioned as a strong partner as Vertical progresses toward civil and defence applications of its VX4 platform.

Stuart Simpson, CEO, Vertical Aerospace, said: “We are bringing the VX4 to market alongside leading global partners, and deepening our successful partnership with Syensqo as our advanced-materials supplier is a vital step in that journey. Their decades of expertise in lightweight, high-performance composites - combined with our shared commitment to safety and certification - will help us deliver a resilient, agile aircraft as we progress toward commercial operations.”

Rodrigo Elizondo, President Syensqo Composite Materials, said: “We are honored to deepen our collaboration with Vertical. Our advanced composite and adhesive technologies are designed to push the boundaries of lightweighting and performance, supporting the VX4’s journey toward safer, cleaner and more efficient air mobility. As Vertical moves into certification and industrialisation, we look forward to bringing our scientific expertise and strong customer partnership to support the VX4’s successful entry into full-scale production."

This expanded partnership with Syensqo comes as Vertical continues to formalise its core supply chain for the certification aircraft, working alongside Honeywell, Aciturri, and other global partners.

Vertical plans to unveil its new aircraft design on 10 December in London, highlighting the VX4’s industry-leading design, enhanced passenger and luggage capacity, and certification-ready global architecture.
