## Summary

The procurement process involves the Ministry of Defence as the buying organisation, with the tender titled "62225447 ACSR Controller Obsolescence" focusing on repair and maintenance services of helicopters. This project addresses the Active Control Structural Response (ACSR) Controller obsolescence for Merlin Mk4/4a helicopters, ensuring compatibility with the fleet. The procurement, concluded at the award stage, was valued at £6,845,616, and the service location is specified in the South West region of the United Kingdom, specifically in Yeovil, England. The procurement method used was a selective call-off from a framework agreement. The contract commenced on 29th September 2025 and is set to complete by 5th March 2030.

This tender offers significant growth opportunities for businesses specialising in aerospace engineering and maintenance services. Large enterprises such as defence contractors and helicopter maintenance firms would be well-suited to compete, given the complex technical requirements and the tender's substantial value. Although the procurement was not specifically targeting SMEs or voluntary community and social enterprises, engaging with such high-profile government contracts can enhance a company's industry credentials and potentially lead to further opportunities within the Ministry of Defence and other governmental organisations. The selected supplier, Leonardo Helicopters Ltd, a large organisation with expertise in the aerospace sector, exemplifies the scale and capacity needed to successfully deliver such contracts.

## Notice

Active Control Structural Response (ASCR) Controller Obsolescence, to address ACSR installed on the Merlin Mk4/4a, as it had been identified that only the Mk4/4A would be modified and that the existing ACSR Controllers would be used to support the Merlin Mk2 fleet, therefore there is no commonality between the Merlin Mk4/4A fleet and the Merlin Mk2; the modification does not allow fitment of the existing ACSR Controller once an aircraft has been modified.
