701712461 - CSAT Phase 1 MCN
Authority: Ministry of Defence (Central government)·Consortium: 4 public authorities
What is being bought
Published requirement descriptionThe UK Ministry of Defence (MOD) replaced its fleet of BAe146 transport aircraft stationed at RAF Northolt in June 2022, with 2 x New Dassault Falcon 900LX business jets, by adopting a procurement strategy featuring two phases:
Phase 1: Competitive procurement of two new civil jets with an in-service support package that runs until Sep 2026. These aircraft are owned by the MoD but operated on the Civil Aircraft Register (CAR) and initially operated by a contractor. Phase 1 also included the training of military pilots and cabin crew and the use of these service personnel to complement the civilian pilots in the delivery of the service.
Phase 2: A separate competitive procurement for the embodiment of military modifications onto the aircraft, from 1 Oct 2026 (subject to further take-up of contract options), and provision of in-service support through to Apr 2037, utilising military personnel in the operation of the aircraft, under the Military Aircraft Register (MAR).
NB – this Contract Notice is concerned exclusively with Phase 2. Quantity or scope: The current CSAT fleet consists of 2 x Envoy IV Aircraft (Dassault Falcon 900LX) based at RAF Northolt. Although the Envoy IV are currently operated on the Civilian Aircraft Register (CAR), the intention is to transfer Envoy IV onto the Military Aircraft Register (MAR) prior to the start of the new contract.
Scope comprises two key requirements:
- Provision of a fully inclusive in-service support solution to support and maintain the Envoy IV Aircraft through to planned OSD of Apr 2037, utilising military personnel in the operation of the aircraft.
- Design and embodiment of military modifications onto the aircraft and ensure certification of airworthiness under MAR, to enable the aircraft to be operated in military airspace and in a non-benign environment. The modifications will be subject to the outcome of a requirements review.
The contract shall be for a term of 5 (five) initial years with options to extend by a further 6 (six) years (taken in single or multiple year intervals).
This contract is being procured under Regulation 18 (Negotiated Procedure) of the Defence and Security Public Contracts Regulations 2011.
The Defence Sourcing Portal (DSP) will be used to manage the procurement process, including evaluation. Access to the DSP is required to complete the DPQQ and access should be requested via the Supplier Registration Page on the DSP.
Following DPQQ evaluation, the Authority intends to invite a maximum of the 4 (four) highest scoring respondents to the ITN phase. Following submission and assessment of the written Initial Tender submissions, all technically and commercially compliant bidders may be invited to a negotiation phase. However, the Authority reserves the right to award the Contract to the Most Economically Advantageous Tender (MEAT) in accordance with the scoring criteria following evaluation of the tenders, without undertaking a negotiation phase.
The Authority anticipates issuing the ITN in December 2024, followed by a bidders’ conference to be held in the UK. Contract award is forecast for March 2026 with contract start in October 2026, though the Authority reserves the right to amend the timetable from time to time.
The Authority trades using the electronic ‘Contracting, Purchasing & Finance’ system (CP&F). Before completing the DPQQ, any interested parties should ensure that they have the ability to trade electronically, and the willingness connect to the CP&F System in the event of being successful.
A Cyber Risk Assessment has been conducted for this requirement to ascertain the level of Cyber Risk present. The result of this assessment is that a Cyber Risk level of 'Low’ exists and therefore successful respondents invited to ITN will need to hold a Cyber Essentials [Plus] certificate and undertake a Cyber Risk Assessment on their proposed supply chain. Respondents can verify their readiness to comply with opportunities bearing this Cyber Risk Level by completing a Cyber Risk Assessment using RAR code: RAR-303384308.
To note: The issue of this Contract Notice (CN) or any future ITN or ITN material is not a commitment by the Authority to place a contract as a result of this competition, or at a later stage. Any expenditure, work or effort undertaken prior to any offer and subsequent acceptance of contract, is a matter solely for your commercial judgement. The Authority has conducted previous industry engagement using Defence Contracts Online (DCO), with a Request for Information (RFI) published in April 2023 and industry day held in July 2023.

- Change The modification will extend the duration of the contract for an additional 2 years at a cost of £26m., Need for additional works, services or supplies by the original contractor/concessionaire: 1. The C-17 Command Support and Airborne Equipment (C17CSAE) Team, part of the United Kingdom (UK) Ministry of Defence (MOD), has a requirement to operate and provide in-service support to the Envoy IV Aircraft (2 x Dassault Falcon 900LX), part of the Command Support Air Transport (CSAT) programme, based out of RAF Northolt, UK. 2. The Aircraft are currently operated and maintained by Centreline Aviation Ltd on the Civil Aircraft Register (CAR), using a combination of civilian and military pilots. This Phase 1 Contract was competed and awarded under the Public Contracts Regulations (PCR 2015) and is due to expire on 31 March 2027. 3. The CSAT Phase 2 requirement, for enduring in-service support and military modification under the Military Aircraft Register (MAR), was competed under Contract Notice Ref: 2023/S 000-036566. The Invitation to Negotiate was withdrawn on 14 November 2025 due to receipt of only one tender, which was deemed unaffordable. 4. Due to the failure of the Phase 2 competition, the UK MOD intends to modify the existing Phase 1 Contract with Centreline Aviation Limited pursuant to Regulation 72(1)(b) of the Public Contract Regulations 2015. The modification shall provide for continued operation and in service support of the Envoy IV aircraft; preparatory and enabling activity associated with potential transition from the CAR to the MAR; continuity of airworthiness management, safety case ownership, crew qualification and operational approvals; and stability of the CSAT operating model pending re-competition. 5. It is necessary to make the modification to afford the Authority sufficient time to run a new competition for the provision of enduring ISS to maintain and sustain the Envoy IV Aircraft through to planned Out of Service Date (OSD) of April 2037, while allowing a minimum of 6 months for any new contractor to transition its operations into the Government Furnished Facilities at RAF Northolt, without an interruption to this essential military capability at a time of rising global tension. 6. The modification will extend the duration of the contract for 2 years and is intended solely as an interim measure. The anticipated maximum value of the modification is £26M. 7. The Contract modification will be a Qualifying Defence Contract subject to the provisions of the Defence Reform Act 2014 and the Single Source Contract Regulations 2014, as amended.
