2026-11-03

The Authority has been engaging on the Land Integrated Operating Services (LIOS) programme for some time and recently provided an industry update on the intended Operating Model (UK02 Notice reference 708004450). The Authority advised during the update that it intended to carry out a Pre Market Engagement (PME) exercise in support of the Integrated Readiness Output Contract (IROC) and Other Platforms and Services (OP&S) elements. This is a calling notice for expressions of interest in taking part in that PME which will be conducted as a Request For Information (RFI) exercise to inform the LIOS team on market conditions, identify routes to market and inform the related procurement strategies. LIOS is a once in a generation opportunity to transform Land vehicle support between 2025-30 and, in doing so, bring MOD and Industry closer to deliver Defence intent in accordance with the Land Industrial Strategy. The vision for LIOS is to deliver longer term, more output-focussed equipment support solutions that proactively and intelligently manage in-scope capabilities through life in accordance with capability management plans. LIOS will deliver sustainable enterprise efficiencies to optimise support and capabilities through-life, combining upkeep, update and upgrade services. IROC, including but not limited to provision of the services currently delivered via the extant Service Provision and Transformation Contract (SPTC), covers a wide range of in-service land equipment and is intended to be a pan Integrated Operating Service (IOS) service provider incentivised to reduce duplication of work, maximise pan-Defence Lines of Development (DLOD) non-Original Equipment Manufacturer (OEM) efficiencies and leverage economies of scale. OP&S including but not limited to provision of PDS via contracts such as PMETS and other support services for in-scope platforms not included within platform IOS contracts from April 2030 and will provide IOS pillar support for those platforms that continue beyond 2030 but do not have a planned programme of Upgrades and Update. IROC and OP&S are initially being managed as 1 over-arching programme until the procurement strategy is matured however there may be 2 or more procurements. The role and full scope of the services will be developed and matured prior to formal procurement activity commencing; this PME exercise will support that process. IROC/OP&S type activities may include but are not limited to:- • Equipment Servicing and Maintenance (Upkeep delivery) • Inventory Procurement & Provisioning • Receipt, Issue, Inspection and Storage (RIIS) of equipment • Post Design Services and Engineering Support Estimated contract dates (start and finish) – 01/04/2030 to 31/03/2045 with possible option years Estimated value - £3-7bn inc applicable VAT
