The SIPRI Arms Transfers Database contains information on all transfers of major conventional arms from 1950 to the most recent full calendar year. It is a unique resource for researchers, policymakers and analysts, the media and civil society interested in monitoring and measuring the international flow of major conventional arms.
The SIPRI Arms Transfers Database was updated on 10 March 2025. The database includes updated data on transfers of major arms for 1950–2024, which replaces all previous data on arms transfers published by SIPRI.
Access the SIPRI Arms Transfers Database directly at https://armstransfers.sipri.org.
The database can be used to address a range of questions, including:
- Who are the suppliers and recipients of major conventional weapons?
- What weapons have been exported or imported by specific suppliers or recipients?
- How have the relationships between different suppliers and recipients changed over time?
- Where do countries in conflict get their weapons from?
- How do states implement their export control regulations?
- Where are potentially destabilizing build ups of weapons occurring?
- What is the relationship between access to natural resources and arms transfers?
The publicly accessible database is updated annually. A brief overview of highlights of the preceding year and more general trends in international arms transfers is published to coincide with the release of each year’s new data set. A broader analysis is published every year in the SIPRI Yearbook.
