The United Kingdom is set to share classified weapons information with Ukraine so it can produce its own version of the Storm Shadow long-range cruise missile, a system jointly designed by the UK and France. Prime Minister Andy Burnham announced the move during his first foreign trip as prime minister, in Kyiv.
The planned transfer comes as Ukraine faces continuing Russian air and missile attacks and uncertain United States backing. France has made a similar move, while the UK and other European allies are seeking to strengthen Ukraine’s ability to produce and use advanced weapons independently.
What Storm Shadow gives Ukraine
Storm Shadow missiles, known as SCALP in France, have a range of about 560km (350 miles) and can strike targets up to 240km (150 miles) inside Russian territory. Their navigation systems allow them to operate at night and in all weather conditions.
Unlike cheaper drones that Ukraine produces in large numbers and uses against softer targets, Storm Shadow is intended for heavily fortified or well-guarded sites protected by stronger defences. The missiles are estimated to cost about $1m each, making them weapons for more carefully selected attacks.

Why the production plan matters
Ukraine already designs and manufactures longer-range systems including the Neptune and Flamingo cruise missiles, as well as large numbers of drones and interceptors. Analysts cited in the source material said licensed Storm Shadow production would give Ukraine access to specialised knowledge and industrial processes that could otherwise take substantial time and resources to recreate.
The main potential benefit is quantity. Ukraine has had to use limited stocks of advanced weapons selectively, while Russia has increased production of drones and missiles. More domestically produced cruise missiles could help Ukraine strike facilities supporting Russian attacks, although the effect on the balance of firepower is not yet certain.
Timeline and obstacles
The UK and France hope to help Ukraine establish a production line by the end of the year. Analysts estimate that a new batch of cruise missiles of this complexity could take about two years from a contract being awarded to delivery, so the timetable for meaningful output remains uncertain.
More context: Ukraine’s domestic ballistic missile capability could emerge in months.
Production would also depend on an international supply chain and on resolving restrictions around sensitive United States technologies incorporated into Storm Shadow. Missile factories in Ukraine would be valuable Russian targets, making protection, dispersed manufacturing and reliable supplies of critical components central challenges.
The wider political signal
Burnham’s Kyiv visit coincided with Ukraine’s 35th anniversary of independence from the Soviet Union. He appeared with President Volodymyr Zelenskyy at a ceremony and was due to co-chair a meeting of the Coalition of the Willing, a group of countries prepared to support Ukraine.
The decision contrasts with US President Donald Trump’s recent reluctance to transfer the technology needed for Ukraine to manufacture Patriot air-defence interceptors. Analysts said the British and French willingness to share classified missile-production knowledge could set a precedent for allied cooperation, but it remains unclear whether it will change Washington’s position on Patriot technology.
