New START Treaty Inspection Activities

What is the difference between a “Type One” and a “Type Two” inspection?

The New START Treaty provides for 18 on-site inspections per year. There are two basic types of inspections. Type One inspections focus on sites with deployed and non-deployed strategic systems; Type Two inspections focus on sites with only non-deployed strategic systems. Permitted inspection activities include confirming the number of reentry vehicles on deployed Intercontinental Ballistic Missiles (ICBMs) and deployed Submarine Launched Ballistic Missiles (SLBMs), confirming numbers related to non-deployed launcher limits, counting nuclear weapons onboard or attached to deployed heavy bombers, confirming weapon system conversions or eliminations, and confirming facility eliminations. Each side is allowed to conduct ten Type One inspections and eight Type Two inspections annually.
