From the U.S. Government Accountability Office, www.gao.gov Transcript for: Nuclear Arms Control Description: New START, a treaty that limits U.S. and Russian nuclear forces, will expire in 2026. The U.S. has identified goals for a successor treaty that include addressing all types of nuclear weapons. The measures for verifying compliance with a New START successor are likely to be similar to those employed for New START, including exchanges of data about deployed strategic delivery vehicles, inspections at relevant bases, and use of satellites. Future treaties could include more extensive nuclear weapons limits. Verifying such treaties may require more advanced technologies-such as devices to measure weapons' radiation signatures-which the U.S. is researching and developing. Related GAO Works: GAO-23-105698. Nuclear Arms Control: U.S. May Face Challenges in Verifying Future Treaty Goals Released: September 2023 [ GAO's Allison Bawden, Director, National Resources and Environment, speaking ] [ Allison Bawden: ] The current U.S.-Russian arms control treaty limiting long range nuclear weapons deployed on missiles and bombers expires in 2026. Prospects for negotiating a new treaty with Russia do not currently look promising. Nevertheless, the U.S. has identified goals for a successor treaty that include addressing all types of U.S. and Russian nuclear weapons. These would include nuclear weapons in storage and shorter range weapons. While the U.S. goals would limit a broader range of weapons, officials largely expect to use current methods to verify that each country complies, such as on-site inspections and satellite imagery. And officials also expect to use the same proven technologies to verify the number of nuclear weapons at a site during inspections. Beyond the next treaty, future treaties could include more extensive nuclear weapon limits. Verifying such treaties may require more advanced technologies, such as devices to measure weapons' radiation signatures - which the U.S. is researching and developing.
