UK transfers Stone Cloak radar jammer design to Ukraine for mass production

The United Kingdom has announced a new technology-sharing agreement allowing Ukraine to mass-produce the British-designed Stone Cloak radar jammer, a digital system about the size of a computer tablet used on long-range strike drones. Previously, Ukraine only received built versions of the jammer. The announcement was made during Ukrainian President Zelenskyy's meeting with the new UK Prime Minister at the Sea Breeze joint exercise in Portsmouth. The agreement highlights the rapid evolution of defense cooperation, as Ukraine's manufacturing outpaces its donors. Unlike the Storm Shadow missile, which cost $2 million each and involved complex European supply chains, Stone Cloak represents a streamlined transfer of intellectual property. The UK and Ukraine are also jointly developing a new long-range strike drone called Breakstop, expected to deploy within 24 months. The article notes that Ukraine's rapid adaptation cycle in electronic warfare and drone operations is a key lesson for NATO allies.
