CONTRACT TO SUPPLY COUNTER UNCREWED AERIAL SYSTEM TO NATO NATION

MS INTERNATIONAL plc is pleased to announce that its wholly owned subsidiary, MSI Defence Systems Limited, based in Norwich, UK, has been awarded a €19.4m contract by a NATO nation to supply three MSI-DS naval gun systems. The systems will provide Counter-Uncrewed Aerial System protection alongside the MSI-DS system's established naval capability.

The MSI-DS 30mm gun systems will be supplied with radar and optical detection capability, together with the MSI-DS Fire Control System. This integrated configuration will provide the vessels with protection against surface, semi-submersible and aerial threats at a time when adaptable weapon systems are increasingly required.

Delivery of the systems is expected to begin towards the end of 2027, in line with the overall programme requirements.
