At the time, SORT was positioned as "represent[ing] an important element of the new strategic relationship" between the two countries with both parties agreeing to limit their nuclear arsenal to between 1,700 and 2,200 operationally deployed warheads each. It was signed in Moscow on 24 May 2002.

After ratification by the U.S. Senate and the State Duma, SORT came into force on 1 June 2003. It would have expired on 31 December 2012 if not superseded by New START. Either party could have withdrawn from the treaty upon giving three months written notice to the other.

Mutual nuclear disarmament

SORT was one in a long line of treaties and negotiations on mutual nuclear disarmament between Russia (and its predecessor, the Soviet Union) and the United States, which includes SALT I (1969–1972), the ABM Treaty (1972), SALT II (1972–1979), the INF Treaty (1987), START I (1991), START II (1993) and New START (2010).

The Moscow Treaty was different from START in that it limited operationally deployed warheads, whereas START I limited warheads through declared attribution to their means of delivery (ICBMs, SLBMs, and Heavy Bombers).

Russian and U.S. delegations met twice a year to discuss the implementation of the Moscow Treaty at the Bilateral Implementation Commission (BIC).
