The Labour Government’s decision to phase out Britain’s Storm Shadow cruise missile has prompted questions after Ukraine revealed it is in talks to manufacture the weapon’s French equivalent under licence.
As part of Keir Starmer’s long-delayed Defence Investment Plan (DIP), published on 30 June, the Ministry of Defence confirmed that Storm Shadow missiles will be retired in favour of a new generation of lower-cost long-range strike weapons.
The plan states that, having learned lessons from the war in Ukraine, Britain is now shifting towards cheaper, more numerous missiles and autonomous systems.
Yet on the very same day, Ukraine’s government announced progress in negotiations with France to secure a licence to manufacture SCALP-EG missiles – the French version of Storm Shadow – on Ukrainian soil.
Ukraine’s Defence Minister, Mykhailo Fedorov, said discussions were advancing but remained complex because of intellectual property issues and industrial arrangements. He confirmed the talks followed discussions between Ukrainian President Volodymyr Zelenskyy and French President Emmanuel Macron earlier this month.
Storm Shadow and SCALP are effectively sister weapons. Developed through Anglo-French cooperation and manufactured by MBDA, they have been among the most effective long-range missiles used by Ukraine against Russian military targets and infrastructure.
The apparent contrast has raised eyebrows among defence observers. Britain is retiring a missile system that Ukraine appears keen not only to keep using, but potentially to manufacture itself.
The Ministry of Defence argues the decision is not about abandoning long-range strike capability. Instead, ministers say Storm Shadow is an ageing system whose production began in the 1990s and that future conflicts require larger quantities of lower-cost weapons. The Defence Investment Plan specifically refers to a move towards next-generation cruise missiles and hypersonic weapons.
The Government has also pointed to existing Anglo-French work on Storm Shadow’s eventual replacement. In July 2025, Britain and France agreed to continue joint development of future deep-strike missile systems, a programme expected to support more than 1,300 UK jobs.
Nevertheless, critics question the timing.
The Defence Investment Plan includes billions of pounds for drones, artificial intelligence and autonomous systems while also retiring Storm Shadow missiles, Wildcat helicopters and other equipment as part of wider savings measures.
The issue is likely to resonate with those who remember earlier controversies surrounding Britain’s defence and industrial capabilities. Eurosceptics have long argued that the UK sacrificed independent technological ambitions during the 1970s as part of efforts to deepen cooperation with the European Economic Community. One frequently cited example is the cancellation of Britain’s Black Arrow rocket programme in 1971. Black Arrow successfully launched the satellite Prospero into orbit in October that year, making Britain the only nation to develop and then abandon an independent satellite launch capability. Historians continue to debate the extent to which European cooperation influenced that decision, although governments at the time cited cost and changing priorities as the primary reasons.
There is currently no evidence that Storm Shadow’s retirement is connected to the Government’s wider efforts to improve relations with the European Union. Ministers have instead presented the move as part of a broader modernisation strategy designed around lessons from Ukraine and future battlefield technologies.
However, the coincidence of Britain retiring Storm Shadow while Ukraine seeks to manufacture its French counterpart is certain to fuel further debate about whether the UK is giving up proven sovereign capabilities too quickly.
For supporters of the Government’s approach, the decision reflects the reality of modern warfare and the need to invest in the weapons of tomorrow.
For critics, it raises an uncomfortable question: if SCALP remains valuable enough for Ukraine to want to build, why is Britain retiring Storm Shadow now?
