## Summary

Defence Equipment and Support, part of the Ministry of Defence, is procuring in-service support for Mini Demolition Remote Firing Devices used by the Explosive Ordnance Disposal community. These devices initiate explosive ordnance disposal activities and controlled demolitions in both manual operations and remote-controlled vehicle operations. The requirement is to continue support for equipment already in service, maintaining its usability across different device variants and remote-controlled vehicle platforms. Services cover the established support solution for this defence capability, including maintenance, repair, configuration management, safety assurance, technical support and management of obsolescence. The work is delivered across the United Kingdom. It is a defence and security services requirement, classified under CPV 90523200, bomb-disposal services.

This procurement has been awarded by direct award to MAS Zengrange Limited, although the award status is recorded as pending and signature is scheduled for 1 April 2027. The direct award is justified under section 41 of the Procurement Act 2023 and paragraph 7 of Schedule 5, on the basis that the existing supplier is the original equipment manufacturer and changing supplier would create incompatible services and disproportionate technical difficulties in operation or maintenance. The estimated value is £504,167 excluding VAT, or £605,000 including VAT. The contract is for four years from 1 April 2027 to 31 March 2031, with four optional one-year extensions, giving a maximum end date of 31 March 2035. There is one completed lot, marked as suitable for SMEs.

This award indicates a specialist, technically controlled requirement for suppliers with proven expertise in supporting explosive ordnance disposal equipment and associated remote-controlled vehicle platforms. A credible future competitor would need the engineering capability to maintain and repair Mini Demolition Remote Firing Devices, manage configurations across multiple equipment variants, and provide reliable technical support throughout their service life. Experience in safety assurance, maintenance validation, interoperability and obsolescence management would be important, as would the ability to preserve established operating arrangements without disrupting defence operations. The requirement also favours organisations able to retain detailed product knowledge, control technical changes and demonstrate dependable equipment availability. Its SME suitability shows that a specialist small or medium-sized defence engineering business may be capable of meeting the requirement, provided it can evidence the necessary technical competence, assurance controls and operational capacity.

## Notice

The Protect Delivery Team, part of the NAD Group Ministry of Defence (MoD) requires a new contract to provide a continuation of In-Service Support for Mini Demolition Remote Firing Devices. The Firing Devices are used to initiate Explosive Ordnance Disposal (EOD) and controlled demolitions. The Firing Devices are used in both manual operations and Remote-Controlled Vehicle (RCV) operations across the EOD community. Therefore, a replacement contract is required to support the continued use of the equipment. The contract duration will be for a maximum period of 8 years, 4 years plus 4 x 1-year options. The total estimated contract value is PS504,167 (Ex VAT) or PS605,000 (Inc VAT).

### Procurement Information

The PROTECT DT part of NAD Group UK Ministry of Defence, intends to award a contract to MAS Zengrange LTD for the In-Service Support of Mini Demolition Remote Firing Devices (Mini DRFDs) via Direct Award. The contract will be for a term of 4 years plus 4 x Option Years if required at an estimated value of PS504,167.00 ex VAT, (PS605,000.00 Inc VAT). It is considered that this contract can be awarded under section 41 of the Procurement Act 2023 because of the direct award justification specified in paragraph 7 of Schedule 5 (single supplier - additional or repeat goods). 'The public contract concerns the supply of goods, services or works by the existing supplier which are intended as an extension to, or partial replacement of, existing goods, services or works in circumstances where: A. change in supplier would result in the contracting authority receiving goods, services or works that are different from, or incompatible with, the existing goods, services or works, and B. the difference or incompatibility would result in disproportionate technical difficulties in operation or maintenance.' Mas Zengrange LTD are the Original Equipment Manufacturer (OEM) of all variants of the Mini Demolition Remote Firing Devices (Mini DRFD) which are currently in service across all Remote-Controlled Vehicle (RCV) Platforms. These systems form part of an established capability used in support of Defence operations, including Contingency Operations and Military Aid to the Civil Authorities (MACA) taskings. Mas Zengrange Ltd currently provides the established support solution for the capability, including maintenance, repair, configuration management, safety assurance, technical support and obsolescence management activities. Continuity of these arrangements is necessary to ensure the ongoing compatibility, reliability and availability of the capability across all platform and equipment variants. Appointing an alternative supplier would necessitate the transition and re-establishment of support arrangements across a fleet comprising multiple Mini DRFD and RCV configurations. This would result in MOD receiving services which are different from the existing services and would create disproportionate technical difficulties associated with maintaining configuration control, assuring compatibility between system variants, validating maintenance and repair procedures and preserving existing safety and assurance arrangements. Such difficulties would increase the risk of interoperability issues, equipment downtime, degradation of performance, safety risks and reduced operational availability. As the existing supplier and OEM, Mas Zengrange Ltd maintains the specialist technical knowledge, skills and configuration authority required to support and maintain the in-service equipment throughout the duration of the contract. Continued contract delivery by Mas Zengrange Ltd therefore represents the most effective means of maintaining operationally available, interoperable and safe equipment while avoiding disproportionate technical difficulties in operation and maintenance.
