Detailed timeline of UK military assistance to Ukraine (February 2022-present)

Military assistance is being provided to Ukraine by the UK and international partners in support of Ukraine’s right to self-defence under the UN Charter.

Level of military aid

The UK has been one of the leading donors to Ukraine, alongside the US and Germany. To date, the UK has pledged £21.8 billion in support to Ukraine since February 2022.

Of that funding, total military financing stands at £13.06 billion. £10.8 billion is for military assistance that has been gifted (including £3 billion in 2025/26), which is met from the Treasury Reserve and will not come from the Ministry of Defence’s (MOD) main departmental budget. Spending on Ukraine does, however, appear in MOD spending figures towards the end of the financial year as part of the MOD Supplementary Estimates.

A government loan of £2.26 billion announced in October 2024 as part of the G7 Extraordinary Revenue Loans agreement (ERA) (PDF), is additional one-off financing (and part of the overall £13.06 billion). It will be paid back from the proceeds of frozen Russian state assets. £1.5 billion of that ERA loan has been released so far, giving “more military support to Ukraine than ever before”. Military financing for 2025 (direct aid and ERA funding) will be £4.5 billion.

What equipment and training has the UK provided?

The UK has provided both lethal and non-lethal weaponry and equipment, including tanks, air defence systems, artillery, and long-range precision strike missiles. While the UK has committed to training Ukrainian fast jet pilots, combat fighter aircraft will not be provided.

With the exception of the ERA loan, military aid to the Ukrainian armed forces has been gifted by the UK. Equipment is either donated from existing UK defence stocks, rapidly purchased from the defence industry in both the UK and overseas or purchased from the surplus stocks of foreign governments. Such acquisition is either funded directly or coordinated through mechanisms such as the International Fund for Ukraine, to which the UK has committed money. In February 2025 the UK chaired the Ukraine Defence Contact Group for the first time.

The UK is also hosting a training programme (Operation Interflex), which is supported by several allies. Training was expanded in early 2023 to include Ukrainian fast jet pilots and marines. 58,000 personnel have been trained to date. In August 2025 the Ministry of Defence confirmed that the training programme would be extended until, at least, the end of 2026.

Long term security guarantees

In July 2023, the members of the G7, including the UK, set out a commitment to providing long term security guarantees to Ukraine (PDF). On 12 January 2024, the UK was the first country to announce a ten-year year security cooperation agreement with Ukraine. In January 2025 the UK and Ukraine also agreed a 100-year partnership agreement.

As part of peace efforts, the UK and France are leading efforts to establish a ‘coalition of the willing’, increasingly referred to as Multinational Force Ukraine, that could be used to defend any peace agreement that is eventually agreed. For the first time in August 2025, President Trump suggested that the US could offer some form of security guarantees alongside Europe. Russia has openly opposed the deployment of European forces on the ground in Ukraine.
