| Nuclear Weapons Tests | None |
Latvia did not possess or test any nuclear weapons. As a republic within the Soviet Union, Latvia did not have an independent nuclear program or the ability to develop or test nuclear weapons.
All nuclear weapons development, testing and deployment during the Cold War period was controlled by the central Soviet government in Moscow. The individual Soviet republics, including Latvia, did not have their own nuclear weapons capabilities.
There are no records of Latvia ever conducting any nuclear weapons tests or being involved in the Soviet Union's nuclear weapons program. The testing and stockpiling of nuclear weapons was the sole responsibility of the Soviet federal authorities, not the constituent republics.
Since Latvia did not have nuclear weapons, it consequently did not perform any nuclear tests, either openly or covertly. The country's history does not include any incidents or programs related to nuclear weapons.
