The New Strategic Arms Reduction Treaty (New START) sets limits on strategic arms that must be met by the United States and the Russian Federation by February 5, 2018. Each state has the flexibility to determine its own structure for reduction so long as their strategic forces will fall within the aggregate limits of the treaty. Both states are subject to verification measures through on-site inspections, data exchanges, and facilitation of monitoring. The two types of on-site inspections are: Type One which covers deployed and non-deployed strategic systems, and Type Two which only inspects non-deployed. New START does not pertain to testing, development or deployment of programs or long-range conventional strike capabilities. See New START at a Glance for more information.
