Precision aerospace specialist Zenix Aerospace is attending Farnborough Airshow 2026, its first international air show since becoming an independent company on 31 December 2025.

Zenix Aerospace, a $500m global precision aerospace business headquartered in Birmingham, is exhibiting at Farnborough International Airshow 2026 (20–24 July), marking its first major industry appearance as a fully independent group.

The company operates seven manufacturing sites across the United Kingdom, the United States, Thailand and Malaysia — four countries, three continents — and a workforce of over 2,000 colleagues. Zenix was carved out from other organisations on 31 December 2025, establishing a standalone group with its own systems, governance and executive leadership.

Zenix Aerospace specialises in the demanding end of the aerospace supply chain: specialist surface treatments and special processes, precision and hard-metal machining, and complex assemblies. Its programmes span commercial aero-engines and aerostructures, defence, space and industrial gas turbines — sectors where tolerances are measured in microns and quality is not negotiable.

In the six months since independence, Zenix has completed the carve-out on schedule, built out operating-company leadership across all seven sites, and maintained uninterrupted delivery performance and customer quality approvals throughout the transition. The company holds a breadth of approvals and operates specialist processes that are difficult to replicate across a footprint spanning Europe, North America and Asia.

Farnborough is the natural stage for Zenix to introduce ourselves to the international aerospace community as an independent business. In six months we have built the foundations of a standalone group without missing a beat on delivery. We arrive at Farnborough with a clear ambition: to grow into one of the leading independent specialists in our field, both organically and through acquisition. We look forward to meeting the partners and customers who will be part of that journey.

Elevating aerospace.

Zenix Aerospace has marked a significant milestone in its space heritage following the successful flight of seven of its valve parts aboard NASA’s Artemis II mission. Integrated within United Launch Alliance’s upper stage of the Space Launch System — the Interim Cryogenic Propulsion Stage (ICPS) — the valves performed critical cryogenic propulsion functions, reinforcing Zenix’s position as a trusted supplier of precision-engineered components for the world’s most demanding aerospace and space exploration programmes.

Seven Zenix Aerospace valve part numbers flew aboard the historic Artemis II launch in April 2026 as part of ULA’s Interim Cryogenic Propulsion Stage (ICPS), the upper stage of NASA’s Space Launch System (SLS). Manufactured through Zenix Aerospace Ketema in the United States, the space-rated valves perform critical functions including propellant management, pressurization and flow control within the cryogenic propulsion system.

Artemis II represents the kind of mission that defines aerospace excellence, where every component must perform flawlessly in some of the harshest operating environments imaginable. We are proud to be a supplier to ULA and that our valves were selected for such a critical application. We are delighted that our engineering and manufacturing teams have contributed to a program that will inspire a new generation of exploration. The mission also demonstrates the value of long-term investment in precision manufacturing, quality systems and engineering expertise across the aerospace supply chain.

Scott McLartyGlobal Chief Executive Officer, Zenix Aerospace

Derived from ULA’s proven Delta Cryogenic Second Stage (DCSS) architecture developed for the Delta IV launch vehicle, the ICPS leverages decades of flight heritage and operational performance. Zenix’s valves have supported multiple configurations across both the DCSS and ICPS programs, providing reliable performance in the extreme conditions of spaceflight.

The valves operating within the ICPS are designed to manage cryogenic fluids under extreme temperature and pressure conditions, supporting mission-critical propulsion functions during ascent and translunar operations. Their inclusion on Artemis II further strengthens Zenix Aerospace’s position as a supplier of precision-engineered solutions for advanced space, defence and aerospace platforms.

Programs such as Artemis demonstrate the importance of collaboration across government agencies, prime contractors and specialist suppliers. We congratulate NASA, United Launch Alliance and all mission partners on this historic achievement and look forward to supporting future exploration missions as the Artemis program progresses.

Scott McLartyGlobal Chief Executive Officer, Zenix Aerospace

The Artemis II mission marks NASA’s first crewed flight around the Moon in more than 50 years and represents a major milestone in the agency’s long-term strategy for sustained lunar exploration and future missions to Mars.

In our largest deal to date, Sullivan Street Partners has agreed to acquire the Aerostructures business of Senior plc for a total enterprise value of up to £200m. Senior’s Aerostructures business is a premier player in delivering precision-machined airframe, aero engine components and complex assemblies for commercial aerospace, defence and space applications.

With its long track record of excellent operational delivery across the UK, US and Asia, we are delighted to bring this business into the Sullivan Street fold. We will continue to expand the business’ capabilities and scale, with a focus on areas such as manufacturing excellence and supply chain reliability.

Calling upon our extensive carve-out and operational expertise, we are working alongside Senior to ensure a seamless separation of this unit, with plans to rebrand underway. We’ve got an exciting journey ahead as we support the business into becoming an independent market-leading supplier.

We are looking forward to working closely with the management team to continue delivering exceptional customer service and growth. This is a well-established business with clear strengths and we’re excited to take it into its next chapter and expand the reach of its high-quality capabilities.
