Boeing Defence UK

Boeing Defence UK (BDUK), is a subsidiary of The Boeing Company. Employing more than 1,400 people, it supports major UK programmes such as Apache, Chinook, C-17 and P-8A.

BDUK is comprised of four business units including MOD Services, training, government services and advanced programmes.

CH-47 Chinook

BDUK’s MOD Services business looks after 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 will also increase the safety of the helicopters, particularly when flying in challenging 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

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.

C-17 Globemaster III


Under the Globemaster III Integrated Sustainment Programme (GISP), Boeing is responsible for all C-17 sustainment activities, including material management and depot maintenance.

P-8A Poseidon

The UK government has bought nine Boeing P-8A Poseidon maritime patrol aircraft, with the first being delivered in 2019. Boeing has jointly funded a £100m investment for a strategic facility at RAF Lossiemouth, which will house the aircraft, have squadron accommodation and maintenance and training facilities.

Future programmes

AH-64E Apache

At the Farnborough Airshow in July 2016 the government announced that it would purchase 50 Apache AH-64E model attack helicopters.

The aircraft are now progressing through a Foreign Military Sale (FMS) upgrade programme that will see 50 of the existing D model fleet being upgraded to E standard capability. BDUK is working with the UK MOD on the development of the support programme that will follow on from the current FMS phase.


In March 2019, the MOD announced it had selected Boeing to provide five E-7 Airborne Early Warning and Control (AEW&C) aircraft to the Royal Air Force. The contract will create several hundred highly skilled jobs for the UK, many based in Cambridge.

Support Chain 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 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 233 staff from the MOD to Boeing.

Government services

Government services provides innovative ways of solving customers’ integrated service management needs, using Boeing’s programmatic approach, world class systems engineering expertise and supply chain partnering.

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) at the FlightSafety International facility in Farnborough, provides both aircrew and maintainer training to a wide range of international operators of the C-17 platform.
  • BDUK also supports non-platform based training with our staff at the Air Battlespace Training Centre at RAF Waddington, providing a training service for the Ministry of Defence's Distributed Synthetic Air Land Training (DSALT) programme. The DSALT programme is delivered by a multi-industry team led by QinetiQ.
  • 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.

Advanced Group UK

Advanced Programmes (The Portal) is a bespoke, multifaceted, globally networked, state-of the-art analysis, experimentation and engagement facility that uses advanced technologies to produce robust, analytical, structured and defensible evidence for decision makers.

The Advanced Systems team is the hub of Boeing UK’s research and development (R&D). They 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 the investment of Boeings significant budget to a number of UK universities, where post graduate research is funded across a broad range of activities.
