Overview
- Zelenskyy met Prime Minister Andy Burnham at a Portsmouth naval base on Monday, where Downing Street announced the UK would hand over the intellectual property for the Stone Cloak electronic warfare system to Ukraine.
- Stone Cloak is a tablet-sized jammer that can be fitted to drones to hinder Russian air-defence tracking, and the UK Ministry of Defence has already supplied thousands of the devices to Ukrainian forces.
- The IP transfer authorises Ukrainian mass production of Stone Cloak so Kyiv can scale its drone operations and sustain jamming capability on the front line.
- Burnham and Zelenskyy met more than 200 Ukrainian service members completing Exercise Sea Breeze in the UK, using the visit to underline continuity in London’s support as Zelenskyy prepares for talks in Washington.
- Downing Street framed the move as deepening defence-industrial ties that could feed into future UK weapons programmes such as Project Brakestop and as part of roughly £25 billion of UK support to Ukraine since 2022.
