## Summary

The Ministry of Defence (MOD), located in Bristol, United Kingdom, has awarded a contract under the direct award procedure to Rowden Technologies for the Provision of Support Services to the TacSys Dismounted Data System (DDS). The contract, valued at £4,800,000 gross, commenced on 17 September 2025 and is set to conclude on 31 March 2026, with possible extensions until 31 August 2026. This procurement, classified under the defence security special regime and the engineering design services industry category, bypassed a competitive tendering process due to technical requirements and repeat service provisions. Rowden Technologies had previously been responsible for designing the Dismounted Situational Awareness (DSA) project, making them uniquely qualified to support the DDS system based on their existing expertise and the continuity needed for the project.

This tender presents a substantial opportunity for small to medium enterprises (SMEs), especially those specialising in engineering design services within the defence sector. Given the unique technical knowledge required, businesses that have previously engaged with the MOD or have experience in DSA systems will find this contract particularly advantageous for growth. It also indicates a potential for contracted work in upcoming similar projects, thus encouraging businesses to position themselves as key partners in future MOD endeavours. With the right credentials, enterprises can leverage this contract as a stepping stone to securing longer-term engagements within the defence sector.

## Notice

The DDS requirement is to deliver a quantity of radios and ancillaries to be connected to provide the DDS system. The design to be used to deliver is owned by the MOD and was delivered as part of the Dismounted Situational Awareness (DSA) project by Rowden Technologies. The DSA project has been delayed but the design has been used by other MOD teams. Rowden continuation of support is required to deliver DDS capability, building on work they have already completed as the Design and Integration Partner for DSA project.

### Procurement Information

The TacSys Service Executive (SE) within Defence Digital (DD), part of the UK Ministry of Defence (MOD), have placed with Rowden Technologies a 7-month contract for the Provision of Support Services to the TacSys Dismounted Data System (DDS). It was considered that this contract can be placed using a Direct Award Procedure pursuant to Schedule 5, Paras 6 & 7, of the Procurement Act 2023 (PA23) due to technical reasons and the supply of repeat services. Following the competitive procedure through the Digital Outcomes and Specialists 5 (DOS 5) framework, the MOD awarded initial Design and Integration Partner (DIP) 2-year contract to Rowden Technologies in July 2021. The scope of the contract was to deliver a DSA system design, which would be used by the MOD to carry out an Assessment Phase competition and to supply the Dismounted Situational Awareness (DSA) system at scale. This design was delivered and has been extensively used and further developed by the MOD and will be used to deliver DDS requirement. As such a new short-term support contract is required prior to planned competition for a longer term contract. Rowden were responsible for the development and delivery of the DSA system design and are currently the only company who have the requisite technical knowhow, expertise and experience to carry out the activities required for the DDS. A change of supplier at this time would introduce disproportionate technical difficulties in both the operation and maintenance of the DDS system, resulting in a loss of capability. Due to the above reasons the requirement will continue as a single source requirement.
