1993. START-2 agreement

20 years ago, on January 3, 1993, in Moscow, Boris Yeltsin and George Bush Sr. signed an agreement on a further reduction in strategic offensive weapons (START-2). The contract prohibited the use of ballistic missiles with separated head parts.

After in June 2002 the United States left the software agreement from 1972, Russia in response left START-2. Instead of START-2, SNP acted (an agreement on a reduction in strategic offensive potentials), which was signed in Moscow on May 24, 2002. The term of this contract expired on December 31, 2012. It provided for a reduction in the number of nuclear warheads standing on combat duty to 1700-200 for each of the parties.

Now the START-3 agreement is valid, signed by Dmitry Medvedev and Barack Obama on April 8, 2010 in Prague. According to the START-3, the number of warheads is reduced to 1550, and the number of their carriers is up to 700. The contract is valid until February 5, 2021.
