U.S. REDUCING NUCLEAR WEAPONS: AIR FORCE DEPLOYED MISSILES DROP TO LOWEST LEVEL IN 60 YEARS

The Air Force's intercontinental ballistic missile force will reduce its nuclear missiles from 450 to 400, the first reduction in a decade, by April. The plan has long been in place. President Barack Obama renewed the deal with Moscow in 2010 and in 2014 announced he would downsize the Air Force's intercontinental ballistic missile force.

Under the original deal signed by the U.S. and the USSR in 1991, Moscow and Washington could deploy up to 1,600 intercontinental ballistic missiles and 6,000 warheads. The new deal stated that each nation may have a maximum of 700 deployed intercontinental ballistic missiles, submarines and bombers, along with 1,500 warheads. Both nations have until February to meet the terms of the treaty.
