US and Russia Conclude Arms-Control Treaty

reporter writes "According to a report just published by the NY Times, Washington and the Kremlin have finalized an agreement on limiting nuclear weapons and related hardware. Notably, the agreement does not restrict American development of an anti-missile shield. Quoting: 'The new treaty will reduce the binding limit on deployed strategic nuclear warheads by more than one-quarter, and on launchers by half. It will reestablish an inspection and verification regime, replacing one that expired in December. But while the pact recognizes the dispute between the two countries over American plans for missile defense based in Europe, it will not restrict the United States from building such a shield. ... The specific arms reductions embedded in the new treaty amount to a continuing evolution rather than a radical shift in the nuclear postures of both countries. According to people in Washington and Moscow who were briefed on the new treaty, it will lower the legal limit on deployed strategic warheads to 1,550 each, from the 2,200 allowed as of 2012 under the previous treaty. It would lower the limit on launchers to 800 from the 1,600 now permitted. Nuclear-armed missiles and heavy bombers would be capped at 700 each.'"

Do MIRVs count as 1 warhead?

[molo]

For those that don't know, one ICBM or SLBM rocket can launch multiple hydrogen bombs. This is known as MIRV (multiple independently targetable reentry vehicles). Each one can be aimed at different target. Does such a system count as one warhead, or do each of the bombs count separately?

Thanks.
