Weapons deliveries to Ukraine dropped significantly in 2025, SIPRI reports

Arms deliveries to Ukraine in 2025 fell noticeably compared with the previous two years of the war.

These conclusions appear in a new report by the Stockholm International Peace Research Institute (SIPRI).

According to the researchers, while Ukraine received record volumes of Western military aid in 2023 and 2024, the flow of deliveries in 2025 was significantly smaller.

SIPRI does not provide specific figures, but says that arms deliveries to Ukraine last year were “substantially lower” than in 2023 and 2024.

The main reason for this was a reduction in U.S. military assistance.

At the same time, SIPRI emphasizes that it is difficult to assess the exact scale of the decline. In 2025, the level of secrecy surrounding U.S. arms shipments to Ukraine increased significantly, meaning many details about the systems delivered and their quantities are not being published.

Meanwhile, European countries—as well as Canada and Australia—continued to transfer large batches of weapons to Ukraine and said they are ready to keep supporting these supplies going forward.

Over the five-year period 2021–2025, Ukraine nevertheless remained the world’s largest recipient of arms, receiving about 9.7% of all global transfers of major weapon systems. The main suppliers during this five-year span were the United States, Germany, and Poland, with the U.S. accounting for about 41% of all arms deliveries to Ukraine.

Overall, the five largest recipients of major weapon systems in 2021–2025 were Ukraine, India, Saudi Arabia, Qatar, and Pakistan.

As a reminder, in 2025 Germany reduced its weapons deliveries to Ukraine by billions of euros.
