What is being bought
The Secretary of State for Defence (the Authority), through the Sonar and Maritime Sensors (SaMS) Project Team within Defence Equipment & Support (DE&S), intends to place a 5.5-year contract, with Ultra Maritime UK (UMUK) for the In-Service Support of the Submarine Acoustic Warfare Control System (SAWCS) Stores Control Unit (SCU).
SAWCS is a bespoke Inboard countermeasure control system developed exclusively for Royal Navy (RN) submarines. It is used with Submarine Counter-measure Acoustic Device (SCAD) 101/102 providing defence to RN submarines from hostile torpedoes by providing a torpedo decoy capability. Support will be provided to the RN submarines fitted with SAWCS to maintain availability of the units, including spares maintenance, engineering support and obsolescence management.

No-engagement rationaleNot published |
Procedure rationaleIt is considered that the direct award of the contract is lawful pursuant to Section 41 and paragraph 7 of Schedule 5 of the Procurement Act 2023 for additional or repeat goods, works and services. The proposed In-Service Support is a continuation of the existing support provided by UMUK under the current contract.
The SCU is a safety-critical piece of equipment that relies on high integrity software to operate. A change in supplier would result in the Authority receiving services that are different from, or incompatible with, the existing services, and the difference or incompatibility would result in disproportionate technical difficulties in operation or maintenance. In particular:
1. UMUK are the original equipment manufacturer who have the experience and technical expertise to maintain the equipment. A new supplier would need a disproportionate amount of time to build the detailed technical understanding of the intricacies of the SCU and interfaces in order to maintain the safe operation of the equipment from the outset of the contract and throughout its duration, ensuring no gap in operational capability.
2. If the hardware, interfaces or processing architecture change as a result of the Authority receiving a different service, and this in any way impacts on the current software build, the costs of embodying that change would be highly cost-prohibitive and take a disproportionate amount of time to regain safety qualification. Without this qualification the system would not be deemed ‘Safe to Operate’ and would have to be withdrawn from service.
These factors increase the risk that a change of provider would result in difference or incompatibility which would bring about disproportionate technical difficulties in operation or maintenance. For these reasons it is not considered that another provider could meet the required level of support without introducing an unacceptable level of technical, safety and security risk to MOD capability. |
