The UK Ministry of Defense (MOD) supply arm, Defense Equipment and Support (DE&S), has signed a $108.42m (£80m) contract with Bristol-based Centreline.
Under the contract, Centreline will deliver two Dassault 900LX aircraft and provide two years of initial support.
The contract includes additional three-year options that will be exercised as needed.
These new aircraft will replace four BAe146 aircraft and help Britain’s Royal Air Force (RAF) cooperate with key partners and allies.
Dassault 900LX aircraft are equipped with smaller engines for lower fuel consumption and emissions.
He was selected as a substitute in the competition as he met the performance, cost and time requirements.
The UK’s Royal Air Force (RAF) program manager, Air Commodore Martin, said: ‘The Defense and RAF Equipment and Support Teams have done an incredible job of procuring these modern and efficient aircraft. I look forward to seeing them support the UK’s defense mission and our wider strategic partnerships.
Under the two-phase programme, the aircraft will initially be operated by a mixed crew of civilian and RAF personnel.
To achieve maximum capability, these aircraft will be upgraded with missile jamming systems and military communications.
Meanwhile, two BAe 146 aircraft, after 40 years in service, will be kept at the British Airliner Collection in Duxford, Cambridgeshire, and the South Wales Aviation Museum at St Athan in South Glamorgan.
The other two aircraft were acquired by a civilian operator.
