Blueprints for Storm Shadow
The United Kingdom agreed to share classified information on UK-made components of the Franco-British Storm Shadow/SCALP cruise missile with Ukraine, clearing the way for domestic assembly after months of negotiations between Kyiv and Paris over licensing and local production.
“On Ukraine’s 35th anniversary of independence, the Ukrainian people should be in no doubt – the UK is behind you today and for as long as it takes”
Prime Minister Andy Burnham made the announcement during his first foreign trip as prime minister to Kyiv for Ukraine’s 35th anniversary of independence, where he said, “On Ukraine’s 35th anniversary of independence, the Ukrainian people should be in no doubt – the UK is behind you today and for as long as it takes,” and he also met Volodymyr Zelenskyy.
The UK’s decision authorizes defense company MBDA to release sensitive British technical information needed for production, and The Telegraph said it would allow Kyiv to manufacture the long-range weapon for use in its war against Russia.
The missiles at the center of the transfer are described as air-launched cruise missiles with a range of about 250 kilometers, and The Telegraph said they feature bunker-busting warheads and have been used in strikes including a September 2023 attack on Russia’s Black Sea Fleet headquarters in Sevastopol.
The move was also framed as part of a broader effort to strengthen Ukraine’s air defences as the Coalition of the Willing met in Kyiv, where allies condemned Russia’s “systematic and escalating strikes against Ukraine’s cities, critical infrastructure and civilians” and pledged to strengthen Ukraine’s air defences “as a matter of urgent priority.”
Russia Denounces the Move
Russia condemned the UK decision to share classified technical information on Storm Shadow/SCALP cruise missiles, with Kremlin spokesperson Dmitry Peskov calling it “fuel on the fire” and saying Moscow views the move “extremely negatively.”
Peskov accused London of doing everything possible “to prevent any progress in the peace process,” and he also claimed Russian forces were already gathering information on potential production sites for the missiles and other military equipment in order to target them.
In Kyiv, Burnham hit back at the accusations, telling reporters, “Who started the fire? That’s the question, isn’t it?” as he addressed the decision to declassify information on UK components.
The Guardian reported that Burnham compared Ukraine’s struggle to Britain’s fight against Nazi Germany, saying, “My nation kept the flame of European freedom alive in the 20th century, you hold that flame in the 21st,” while Russia warned of escalation in tensions after the blueprints were presented.
The Kyiv Independent added that the release of previously classified missile technology could enable Ukraine to assemble the weapon domestically, while Douglas Barrie cautioned that establishing production would not happen immediately and would be expected to take “a number of years rather than a number of months.”
Patriot Shortages and Next Steps
The blueprint transfer is positioned alongside Ukraine’s stated need for air defence against intensifying Russian missile attacks, with the AOL.co.uk report saying Ukraine’s most urgent military need remains defences against ballistic missiles and that it is critically dependent on US-made Patriot systems and PAC-3 interceptors.

AOL.co.uk said Ukraine has been pressing Washington for additional interceptor missiles and for permission to manufacture them domestically, while US ambassador to NATO Matthew Whitaker later stressed that PAC-3 technology remained tightly controlled under US export rules and that no long-term production agreement was likely before the winter.
In Kyiv, Burnham also urged coalition partners to help secure more US-made Patriot missiles, and The Guardian quoted him saying the coalition was “doing everything we can all do and working with our allies outside of this coalition to dig into our own stocks and help others dig into their stocks”.
The Spectator framed the Storm Shadow/SCALP assembly timeline as far in the future, saying the earliest Ukrainian-assembled models could appear is 2027, while it argued that what Zelensky “really needs now is missiles for his US-provided Patriot interceptors.”
Meanwhile, the Türkiye Today report said Zelenskyy received 675 Patriot interceptor missiles in 2023, 364 in 2025, and an expected 264 in 2026, and it said Ukraine requested 360 interceptors from allies and hoped to receive at least 300 ahead of winter.
