It pertains to the "Out of Service Date Extension Programme D&M LH," focusing on extending the operational lifetime of military transport helicopters. The procurement is conducted under the "defenceSecurity" special regime, utilising a direct award method, justified by technical complexities and certification constraints. The process has reached the "complete" stage as of 19 June 2026. The procurement encompasses goods with an estimated contract value grossing £27,950,400, commencing on 1 June 2027, and concluding on 31 March 2035, with potential extensions available until 31 March 2040. This tender provides significant opportunities for large businesses, especially those with expertise in military transport and helicopter maintenance, as it requires specialised knowledge and capabilities. Suppliers like Leonardo UK Limited, with its large-scale operations and prior experience, are well-suited to fulfil the needs set by the contract. The potential for contract renewal and extension amplifies the opportunity for sustained business growth within the defence industry sector. Businesses with the requisite technical skills and capacity to navigate complex defence specifications stand to gain a strategic advantage and build long-term partnerships with government entities. ## Notice Out of Service Date Extension Programme D&M LH ### Planning Information Direct award and workshop with supplier ### Procurement Information ssessment Phase activity included a review of whether the OSDEP requirement could be delivered through competition or required a single source approach. This concluded that both Lockheed Martin UK Ltd and Leonardo Helicopters UK Ltd hold the exclusive technical know-how, engineering expertise and manufacturing capability necessary to deliver the required modifications. The proposed suppliers are the recognised Design Authorities for the Merlin Mk2 and Mk4/4A platforms and are responsible for certification and continued airworthiness. Delivery of the requirement necessitates integration within existing platform architectures and safety-critical systems, continuity of Design Authority and certification activity, and access to platform-specific engineering capability, tooling and expertise. Any attempt to introduce an alternative supplier would require replication or transfer of Design Authority capability and associated certification frameworks. This would result in disproportionate cost, delay, and unacceptable technical and safety risk. The Authority therefore considers that the absence of competition arises from technical and certification constraints rather than reliance on exclusive rights, and that no reasonable alternatives or substitutes exist. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/057953-2026 | | Notice type | UK5 - Transparency Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Direct | | Procurement method details | Direct award | | Tender suitability | Not specified | | Awardee scale | Large | | All stages | Planning, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 19 Jun 2026 | | Submission deadline | Not specified | | Future notice date | 19 Jun 2026 | | Award date | 19 Jun 2026 | | Contract period | 31 May 2027 - 31 Mar 2035 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £23,292,000 | | Lots value | Not specified | | Awards value | £232,920,000 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Pending | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | DEFENCE EQUIPMENT AND SUPPORT | | Locality | BRISTOL | | Post town | Bristol | | Postcode | BS34 8JH | | Country | England | | ITL 1 | TLK South West (England) | | ITL 2 | TLK5 West of England | | ITL 3 | TLK52 Bath & North East Somerset and South Gloucestershire | | Local authority | South Gloucestershire | | Electoral ward | Stoke Park & Cheswick | | Westminster constituency | Filton and Bradley Stoke | | Delivery location | Not specified | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | LEONARDO | ## CPV Codes ### Divisions - 35 - Security, fire-fighting, police and defence equipment ### Codes - 35612400 - Military transport helicopters ## Release History - 19 Jun 2026 at 10:14 - AwardUpdate - UK5 - Transparency Notice - https://www.find-tender.service.gov.uk/Notice/057953-2026 - 19 Jun 2026 at 10:00 - Award - UK5 - Transparency Notice - https://www.find-tender.service.gov.uk/Notice/057933-2026 - 19 Jun 2026 at 09:44 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/057920-2026 - 19 Jun 2026 at 09:35 - Planning - UK1 - Pipeline Notice - https://www.find-tender.service.gov.uk/Notice/057910-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/057953-2026 19th June 2026 - Transparency notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/057933-2026 19th June 2026 - Transparency notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/057920-2026 19th June 2026 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/057910-2026 19th June 2026 - Pipeline notice on Find a Tender ## Notice URLs - https://www.gov.uk/government/organisations/defence-equipment-and-support - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
