BACKGROUND
Defence Equipment and Support (DE&S) is an arm's length body of the Ministry of Defence, which delivers equipment and support services to the Royal Navy, British Army, and Royal Air Force. DE&S play a critical role in keeping the United Kingdom safe and prosperous, and making sure the front-line have the right kit at the right time. From fighter jets to food deliveries, from patrol boats to protective clothing, DE&S deliver effective and innovative kit to front-line forces.
Within the new DE&S structure, the Power Propulsion and Auxiliary (PPA) team has been set up as a technology area, working across different areas of defence to deliver and sustain systems that generate operational energy, to provide propulsion (e.g. prime movers/engines and transmissions fitted to platforms), and cross-cutting auxiliary systems, including life support, fire-fighting, medical, and catering equipment.
Preliminary Market Engagement (PME) was conducted during May 2025. The Authority has completed it's consideration of the outcomes of this engagement and is now preparing to issue a UK4 - Tender Notice for the purposes of conducting a Competitive Flexible Tender Procedure as regulated by the Procurement Act 2023. It should be noted that the PME also explored how it may incorporate its water purification requirement for its Army master equipment, however the Authority does not currently plan to include the Army Master Equipment requirement within this procurement.
