Today marks exactly one year since the signing of the Century Partnership Agreement between Ukraine and the United Kingdom. The Ministry of Defense summarizes its results.
The United Kingdom remains one of Ukraine’s key and most consistent security partners, providing large-scale, long-term, and systematic military support in response to Russia’s full-scale aggression.
In 2025, the total support provided to Ukraine by the United Kingdom amounted to £4.5 billion, the highest annual figure since the start of the full-scale war.
A significant portion of this amount is the UK’s contribution to the G7 Extraordinary Revenue Acceleration (ERA) mechanism—£2.26 billion in credit support, repaid from the profits of frozen Russian assets.
A separate priority of British assistance is strengthening Ukraine’s air defense. In 2025, the United Kingdom invested £600 million in air defense capabilities, focusing support on protecting Ukrainian cities, critical infrastructure, and the energy system from Russian attacks.
As part of the ERA contribution, £70 million was allocated for the purchase of 350 ASRAAM missiles to enhance air defense.
Additionally, Ukraine received a new specially designed air defense system, Gravehawk, jointly financed by the United Kingdom and Denmark. Two prototypes of this system were tested in Ukraine in the fall, and 15 more units are expected to be delivered over the year.
The United Kingdom also makes a substantial contribution to the development of Ukraine’s drone capabilities. In just six months, over 85,000 military drones were delivered, alongside £600 million in investments to accelerate their production. A new bilateral agreement between Ukraine and the UK on battlefield technology exchange is expected to further boost UK drone production specifically for Ukraine’s needs.
Furthermore, the United Kingdom leads the Drone Coalition and the Maritime Capabilities Coalition.
Defense-industrial cooperation is another key area. The previously signed Defense Industry Support Agreement between Ukraine and the United Kingdom expanded the list of military equipment that can be financed through £3.5 billion of UK export financing. This has already enabled the implementation of a £1.6 billion contract, under which Thales is supplying Ukraine with 5,000 light multi-purpose LMM rockets, produced in Belfast. Hundreds of these rockets were delivered to Ukraine five months ahead of schedule.
The United Kingdom also plays a key role in training Ukrainian military personnel. In 2025, £247 million was allocated for training, and the program has been extended at least through the end of 2026. Under Operation INTERFLEX in the UK, over 62,000 Ukrainian servicemen have already undergone training.
Additionally, the UK administers the International Fund for Ukraine, through which military equipment is procured for the Defense Forces. The total commitments of partners within the fund already exceed £2.1 billion, including new contracts worth £30 million with Anduril UK for the supply of modern unmanned systems.
It is worth noting that overall, the United Kingdom has already provided Ukraine with £10.8 billion in military aid since the start of the full-scale invasion. London has announced and formalized in the Century Partnership Agreement its strategic decision to support Ukraine at a level of at least £3 billion per year through 2030–2031—and as much as necessary—emphasizing a shift from one-off aid packages to long-term planning of security support.
The scale and structure of British aid demonstrate the strategic nature of the partnership between Kyiv and London. It is not just about supporting Ukraine during wartime but about deliberately building long-term defense capabilities capable of guaranteeing national security and stability in the broader European region.
