UK to share classified Storm Shadow missile technology with Ukraine to enable domestic production

Aug 23, 2026

During a visit to Kyiv on Ukraine's 35th Independence Day, British Prime Minister Andy Burnham announced that the UK will allow defense firm MBDA to share classified technical data on British components of the SCALP/Storm Shadow cruise missile. This declassification aims to help Ukraine and France establish local assembly lines for the long-range weapon. While the Kremlin condemned the move as adding fuel to the fire, military experts warn that establishing domestic production of these complex missiles will face severe supply chain challenges and likely take months or years to impact the conflict.

Storm Shadow technology declassification

▪The SCALP missile is the French-produced version of the UK's Storm Shadow cruise missile, incorporating shared French and British technology with a range exceeding 155 miles.
▪British Prime Minister Andy Burnham announced on August 24, 2026, that the UK government agreed to allow defense firm MBDA to release classified technical information on British components for the SCALP long-range cruise missile.
▪The declassification of British component details is intended to enable France and Ukraine to establish local assembly lines for the SCALP missile inside Ukraine.
▪Kremlin spokesperson Dmitry Peskov stated on August 24, 2026, that the UK's decision to share classified missile technology adds fuel to the fire and that the Russian military is actively gathering intelligence to locate and destroy Ukrainian missile production sites.

Ukraine domestic missile production

▪The UK is collaborating with British defense companies under Project Brakestop to rapidly develop a low-cost, long-range cruise missile free of foreign components for supply to Ukraine.
▪Ukraine currently produces 70% of its own weapons, driven largely by the rapid domestic development of drone technology.
▪Ukrainian manufacturer Fire Point is developing its own ballistic missiles and has developed the FP-5 Flamingo cruise missile, which has a range of 3,000 kilometers.

Independence Day diplomatic gathering

▪Ukrainian President Volodymyr Zelenskyy stated during the August 24, 2026, gathering that Ukraine faces a $27-billion defense funding gap this year and requires at least 300 Patriot air defense interceptors to survive the winter.

▪Britain and Ukraine signed a defense partnership on August 24, 2026, to jointly develop artificial intelligence tools, granting British researchers access to Ukraine's Avengers AI Labs.

Production timeline challenges

▪Military experts, including Douglas Barrie of the International Institute for Strategic Studies, state that establishing domestic production of SCALP missiles in Ukraine will likely take months or years to yield operational weapons.
▪The production of SCALP missiles relies on complex global supply chains for sophisticated components, which may prove difficult for Ukraine to source during active conflict.
