London/Kyiv, August 25, 2026: The United Kingdom has agreed to allow European defence manufacturer MBDA to share classified technical information on British-made components of the SCALP long-range cruise missile with Ukraine, paving the way for local assembly and potentially expanded domestic production of the weapon.
The decision was announced during British Prime Minister Andy Burnham’s visit to Kyiv on Ukraine’s Independence Day. The SCALP, known as Storm Shadow in British service, is a Franco-British precision air-launched cruise missile with a range of more than 250 kilometres.
Under the agreement, MBDA will be permitted to release information covering UK-origin components and technology. The move is intended to help Ukraine and France establish assembly lines inside Ukraine, reducing Kyiv’s reliance on imported complete missiles and strengthening its longer-term defence-industrial capacity.
The agreement represents a significant step in Britain’s military support for Ukraine. London has supplied Storm Shadow missiles to Kyiv since the war began and has increasingly backed efforts to strengthen Ukraine’s ability to develop and manufacture weapons domestically.
The announcement also comes alongside broader defence and technology cooperation between the two countries. Britain and Ukraine have signed an artificial-intelligence partnership that will give British researchers and companies access to Ukraine’s Avengers AI Labs and battlefield data, with the aim of developing new defence technologies.
Russia Condemns the Move
Moscow has strongly criticized the British decision. Kremlin spokesperson Dmitry Peskov described the transfer of classified missile information as an escalation and said Britain was adding “fuel to the fire.” Russia has also warned that Ukrainian missile-production facilities could become targets.
The British government, however, has defended its continued support for Kyiv, arguing that strengthening Ukraine’s defence capabilities is necessary while Russia’s invasion continues.
Strategic Significance
The agreement could have important long-term implications for Ukraine’s defence industry. Local assembly would allow Kyiv to develop greater control over the supply chain for a sophisticated long-range strike system while working with European partners.
However, the move is not expected to immediately transform Ukraine’s missile capabilities. Reports indicate that domestically assembled missiles are unlikely to become operational at scale before 2027, meaning the agreement is primarily a long-term industrial and military investment rather than an immediate solution to Ukraine’s battlefield requirements.
The British decision also highlights the growing integration of Ukraine into Europe’s defence-industrial network, as European governments seek to strengthen Kyiv’s ability to sustain its military capabilities amid the continuing war with Russia.
