Marshall Group

Marshall Group, formerly Marshall of Cambridge, is a British company headquartered in Cambridge, United Kingdom. Subsidiaries include Marshall Aerospace, an aircraft maintenance, modification, and design company located at Cambridge City Airport. Other subsidiaries are Marshall Land Systems (ground defence), Marshall Slingsby Advanced Composites, Marshall Fleet Solutions, Marshall Futureworx, Marshall Skills Academy and Marshall Property. Marshall also owns and operates the airport itself.

The company was founded by David Gregory Marshall in 1909. Initially operating chauffeur services, the firm soon branched out into vehicle repair and dealership activities. During the 1930s, Marshall became increasingly engaged in aviation; by the end of the Second World War, the company had trained in excess of 20,000 aircrew for service within the Royal Air Force. It was also engaged in repair and modification of military aircraft during the conflict.

During the postwar era, the Marshall companies have been involved in aerospace and special vehicle engineering, with Marshall Aerospace forming a major part of the group. The company performs all aspects of design, manufacture, maintenance, modification, conversion and logistic support of military, commercial and business aircraft. Traditionally focused on military customers, Marshall Aerospace has increasingly orientated itself towards the civilian sector in recent decades. It employs over 2,000 people and is based on an 800 acre site with 1200000 sqft of covered Aircraft hangar space on the Cambridge Airport site.

In October 2021, Marshall announced that it had decided to move its Aerospace operations to Cranfield Airport (near Milton Keynes) and that "it will leave its current base at Cambridge Airport by 2030". In November 2022, Marshall Aerospace announced that it expects to have left Cambridge Airport "by 2027".

Postwar
Michael Marshall became the company's CEO. He managed the company for several decades, during which time it became one of the largest privately owned businesses in Britain.

Since 1966, Marshall Aerospace has been the designated support company for the Royal Air Force's fleet of C-130 Hercules. It has been formally recognised as a Sister Design Authority for the type since 1988. The company oversaw the introduction of RAF's 25 second generation C-130J Super Hercules fleet, as well as the retirement of half of the service's first generation aircraft. In addition to its domestic support operations, Marshall Aerospace has supported various international operators' own Hercules fleets. Marshall Group has also signed multiple agreements with US defense conglomerate Lockheed Martin to manufacture various components of the Super Hercules on behalf of the latter's for the global supply chain.

Marshall Aerospace functioned as the design authority for the RAF's fleet of Lockheed TriStar tanker and freighter aircraft; as well as the appointed sister design authority for the RAF's Boeing E-3D Sentry. It undertook major maintenance and modification activity on these types, plus a range of other military and commercial aircraft. Notable design achievements include the design and production of Concorde's droop nose and visor in 1967, and a vestibular sled for medical research which flew 112 orbits in Space Shuttle Challenger on STS-61-A in 1985. Marshall Aerospace has also performed a variety of passenger to tanker and freighter aircraft conversions. One unusual project was the conversion of a Lockheed L-1011 Tristar airliner into a launch vehicle for a satellite delivery system, on behalf of Orbital Sciences. Marshall Aerospace was the designated industrial body involved in the Vulcan to the Sky  project, which restored Avro Vulcan XH558 to a flight-worthy condition and supported its operations for numerous years.

In 1992, Marshall bought AWD Trucks. Production in that subsidiary ended in 1998.

Marshall Group has been a long-term partner of Bombardier Aerospace. During 1998, the company was appointed the first independent authorised service centre in Europe for the Bombardier Global Express long-range business jet. In mid 2000, Marshall became involved in the Global Express' manufacturing process, performing interior completions on behalf of Bombardier. During the 2010s, the firm's expertise with the type enabled it to perform extensive modifications of the airframe to produce customised special mission models for military customers. Marshall Aerospace has also performed the production of long range fuel tanks for various Boeing aircraft, including the Boeing 747-400ER and 777-200LR airliners, as well as the P-8 Poseidon multi-mission maritime aircraft.

By 2012, the Marshall Group was reporting an annual turnover in excess of £1 billion and was employing nearly 4,500 staff. During the 2010s, the business made various moves to expand its footprint in commercial aviation, announcing its intention to establish Cambridge Airport as a primary hub for business aviation operations during 2012. In September 2013, Marshall purchased Hawker Beechcraft's services branch at Broughton, subsequently rebranding it Marshall Aviation Services as well as being appointed Hawker's distributor for the UK, Ireland and Scandinavia. That same year, the company also bought FlairJet, an air charter specialist. This move was part of Marshall's strategy to grow its charter fleet five-fold. At this time, Marshall Group was deliberately restructuring its business activities, particularly its sizable aerospace division.

During late 2015, Marshall Group announced that, in response to a downturn in demand from the British armed forces, the firm intended to focus on its growing civilian activities, including the resumption of VIP aircraft conversion work to counteract this. During 2019, the company announced that was planning to relocate its headquarters from its historic home at Cambridge Airport over the coming decade, although it noted there was value in relocating to a nearby location, such as Cranfield Airport, Duxford Aerodrome and RAF Wyton.

Marshall carried out depth maintenance and modified C-130J Super Hercules fleet of Bangladesh Air Force before delivered to Bangladesh. Those were ex RAF aircraft. Marshall also signed a multi-year multi-million-pound support contract for the C-130J fleet.

Activities
Marshall's headquarters is located on an 800-acre site in Cambridge, UK. The group operates worldwide in the fields of aerospace, military land systems and fleet management; the company also cooperated with 67 franchised automotive dealerships across the UK by 2012.

Marshall Aerospace has been involved with all levels of aircraft maintenance, modification and conversion for more than seventy years. The company has the authorisation and experience to work on a range of aircraft from Cessna Citations to Boeing 747s in civil use, and Lockheed C-130 Hercules and Lockheed L-1011 TriStars for the military. Marshall Aerospace carries out maintenance from routine daily maintenance to a full aircraft depot level checks. All forms of conversions, re-configurations, modifications and repairs can be designed and implemented by Marshall Aerospace. The company's commercial aircraft hangar can house a range of different aircraft, for example, one Boeing 747-400, one McDonnell Douglas MD-11 and two Airbus A320s. Marshall also has other hangar space that can hold up to 12 C-130s at a time. Amongst the various facilities it has, the firm possesses the largest quiet test building in Europe.

Besides aerospace, Marshall operates several other divisions. Marshall Group Properties owns Cambridge City Airport, where the company has its main base, and a large portion of the land surrounding it. Over the years, it has embarked on various development projects to expand the airport's facilities and build thousands of homes nearby. The airport itself has been owned and operated by the company since 1937.

Planned relocation
In May 2019, Marshall announced that Cambridge City Airport would be closed to all traffic by 2030 at the latest. The Group plans to redevelop the airport site for around 12,000 homes and 5 e6sqft of business premises. In May 2019, the Group announced that it was deciding between three potential airfields for its continuing operations: Duxford Aerodrome, RAF Wyton in Cambridgeshire, or Cranfield Airport in Bedfordshire. In January 2020 the Group ruled out moving to Duxford due to incompatibility between the defence requirements of the Group and the requirements of the local traffic.

On 6 October 2020, Cranfield University and MADG announced that they had signed an option agreement for the potential relocation of Marshall Aerospace to Cranfield Airport. A spokesperson for MADG cautioned that "it is important to note that the signing of the option agreement does not represent a final decision". In October 2021, the Group announced that it had decided in favour of the Cranfield option and that "it will leave its current base at Cambridge Airport by 2030". Outline planning permission for the development at Cranfield was granted in April 2023.
