  • ON-SITE INSPECTIONS – 18 on-site inspections per year. Ten Type One inspections focus on sites with deployed and non-deployed strategic systems; Eight Type Two inspections focus on sites with only non-deployed strategic systems.
  • UNIQUE IDENTIFIERS (UIDs) – Each ICBM, SLBM, and heavy bomber will be assigned a unique identifier.
  • TELEMETRIC INFORMATION –To enhance transparency and supplement verification provisions.
  • COMPLIANCE – Establishment of the Bilateral Consultative Commission (BCC).

New START Implementation Thus Far:

  • Notifications: Almost 1,500 notifications exchanged through the Nuclear Risk Reduction Centers (movements, launches, data changes).
  • Exhibitions: Three exhibitions required by the Treaty have been completed (Russian RS-24 road-mobile ICBM and launcher; U.S. B-1B heavy bomber; U.S. B-2A heavy bomber).
  • Type One and Type Two Inspections: To date, the U.S. has conducted twelve inspections (eight Type One, four Type Two); Russia has conducted eleven inspections (six Type One, five Type Two).
  • These inspections have taken place at ICBM, SLBM, and heavy bomber bases; storage facilities; conversion or elimination facilities; and test ranges
  • Bilateral Consultative Commission (BCC): Met in early April and signed two non-legally binding Joint Statements memorializing shared understandings of technical issues related to implementation activities. The second session of the BCC is underway in Geneva and will continue to November 2.
  • Telemetry Exchange: Both Parties have conducted demonstrations of telemetric information playback equipment and recording media to be used during telemetry exchanges.


  • The early implementation of the New START Treaty has been successful and is progressing smoothly.
  • The outstanding working relationship that developed during negotiations has carried over into implementation.
  • As expected, there have been differences and concerns with implementation, but both sides have continued to work cooperatively to resolve them.
  • We look forward to reporting further success and additional updates as New START implementation continues.
