Marshall of Cambridge Aerospace Limited

What Marshall of Cambridge Aerospace Limited does

Marshall of Cambridge Aerospace Limited (operating as Marshall Group / Marshall Aerospace) is a privately held UK aerospace company headquartered in Cambridge, founded in 1909. It operates three integrated business lines: Maintenance, Repair and Overhaul (MRO), Engineering Services, and Precision Manufacturing. The company is the world's first authorised Lockheed Martin C-130J Heavy Maintenance Centre and a designated Centre of Excellence for C-130 centre wing box replacements, with continuous C-130 platform expertise since 1966. In 2024 alone it completed nearly 30,000 MRO tasks across 442,000 hours of aircraft work.

The company serves military and government customers (notably the US Marine Corps under a ten-year agreement covering 74 KC-130J aircraft, and the RAF), aircraft OEMs (Lockheed Martin and Boeing, via authorised service centre and P-8 auxiliary fuel tank work), and aerospace prime contractors (including a new sonar module production line with Thales and a flight model for Horizon Aircraft's hybrid-electric VTOL). Engineering Services spans modernisation programmes, capability enhancement, certification and testing (including flight test and UAS flightworthiness), aviation training, and through-life management. Precision Manufacturing delivers complex subsystem assembly and parts manufacturing for critical platforms.

Revenue is generated primarily through long-duration professional services contracts and hardware sales under OEM and government procurement frameworks; pricing is not publicly disclosed and is contract-specific. The company is approaching a significant operational transition, as its Cambridge City Airport site is slated for redevelopment by 2030, prompting a transformational Cambridge East land acquisition intended to support 10,000+ homes and 9,000 jobs. Marshall holds NADCAP, HIOS, and SOC 2 Type 2 certifications, operates an investor relations programme with share auctions and dividend disclosures, and reports under the Marshall of Cambridge (Holdings) Limited parent entity.
