The parties also established mechanisms for checking compliance with the agreement. As part of this agreement, the United States and Russia exchanged data on the status of their nuclear strategic forces, the Voice of America notes.

 According to the latest data exchange on September 1, 2020, Russia claimed 1,447 deployed strategic warheads. By February 5, 2018, both the USA and the Russian Federation had fulfilled the restrictions on strategic nuclear weapons established by the SNO-3 treaty. Since then, their nuclear stockpile has remained at or below the established level.
