Boeing Defence UK

Boeing delivers leading-edge platforms, technology, services and capabilities to bring the best value to the Ministry of Defence (MOD) and UK national security services.

Major UK programmes such as Apache, Chinook, C-17, P-8A and Wedgetail are supported and delivered by Boeing Defence UK (BDUK), a subsidiary of The Boeing Company. Employing more than 1,400 people, BDUK also provides engineering sustainment and support for aircraft in service with the UK armed forces, along with virtual and instructor-led training. Leveraging our established defence business in the UK, and blending our local expertise with our ‘One Boeing’ global approach, BDUK is well positioned to support the UK with its current and future defence and security challenges.

CH-47 Chinook

First arriving in the UK 40 years ago, BDUK maintains the UK’s Chinook fleet of 60 helicopters under the Through Life Customer Support (TLCS) contract, the Digital Automatic Flight Control System (DAFCS) upgrade programme and the Chinook Engine Support Arrangement (CESA).

  • TLCS is a 34 year partnering agreement to provide heavy depot maintenance, modifications and upgrades for the entire fleet.
  • The DAFCS programme is upgrading original analogue cockpits with a new digital avionics suite, greatly improving handling qualities and aircraft stability. It provides increased safety of the helicopters, particularly when flying in challenging and low-visibility conditions.
  • The CESA contract provides support to the UK Chinook engines through a single availability, output-based contract to provide specified levels of engine availability, spares and technical support.

AH-64 Apache

The first two AH-64E model Apache attack helicopters were delivered to the British Army in November 2020. The delivery is the result of an agreement for 50 of the E models signed in 2016 between the U.S. and UK governments. Delivery of the fleet is expected to be completed in 2024.

The aircraft are based at Wattisham Flying Station in Suffolk, where they will be serviced and maintained by Boeing engineers alongside British Army Aviation Technicians from 7 Aviation Support Battalion, Royal Electrical and Mechanical Engineers.

BDUK works closely with Leonardo Helicopters to support the UK’s current Apache D model helicopter fleet. A range of services including technical operation and maintenance, delivering spares and performing repair and overhaul are undertaken.

AH-64 Apache simulator flight training is also delivered at Middle Wallop and Wattisham to support pilot conversion to type, conversion to role and refresher training, along with ground crew and mission planner training programmes. This is complemented by computer aided instruction to deliver theory training for flight and maintenance.


Under the Globemaster III Integrated Sustainment Programme (GISP), Boeing is responsible for all C-17 sustainment activities for the RAF’s fleet of eight, including material management and depot maintenance based alongside their military counterparts at RAF Brize Norton.

P-8A Poseidon

The UK government has bought nine Boeing P-8A Poseidon maritime patrol aircraft. The first one arrived in the UK in February 2020. Boeing has jointly funded a £100m investment for a strategic facility at RAF Lossiemouth, which can house three of the RAF’s nine Poseidon aircraft, accommodation for three squadrons and mission support facilities.

C-17 Globemaster III


In March 2019, the MOD announced its selection of the Boeing E-7 Airborne Early Warning and Control (AEW&C) aircraft for the RAF, which is expected to be in service with the RAF in 2023. It will be a central asset in the RAF’s future Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) Force. The contract will create several hundred highly skilled jobs in the UK, many based in Birmingham with Boeing’s key UK supplier on the Wedgetail, STS Aviation.

Government Information Services

Boeing was awarded the £800m Future Logistic Information Services (FLIS) contract as MOD’s 10-year Support Chain Information Services (SCIS) delivery partner. SCIS aims to improve the reliability and capability of the UK military’s logistic information systems and services that deliver engineering, supply chain and business intelligence information. It replaced more than 120 legacy contracts and included the transfer of staff from the MOD to Boeing.

Training services

The UK arm of Boeing’s training services was established to enhance the delivery of integrated, platform-based military capability to support our customers’ operational requirements.

  • The UK C-17 International Training Centre (ITC) in Farnborough, provides both aircrew and maintainer training to a wide range of international operators of the C-17 platform.
  • Boeing will provide a synthetic training environment for the MOD, which can be used to build live training exercises in a virtual world. The capability, known as Gladiator, will support multiple complex training scenarios, simultaneously and independently of each other. This will allow for more complex training to occur in a structured setting and reduce the cost of carrying out real life training while helping to reduce carbon emissions.
  • The CH- 47 Chinook Digital Automatic Flight Control System (DAFCS) Familiarisation Rig (DFR), is a third generation training device that provides training for RAF technicians and pilots.

The Boeing Portal

The Portal, Boeing’s state-of-the-art analysis, experimentation and engagement facility in Hampshire uses advanced technologies to produce robust, analytical, structured and defensible evidence for senior defence and security decision makers.

The Advanced Systems team based at The Portal is the hub of Boeing UK’s research and development (R&D). The team conduct in-house, company-funded R&D in areas as diverse as data analytics, data visualisation, advanced communications techniques and health and monitoring systems. They also oversee Boeing’s investment in our strategic partnerships with UK universities, where post graduate research is funded across a broad range of activities.
