A railcar-launched ICBM is an intercontinental ballistic missile that can be launched from a train. The first operational example, and the best-known, is the Soviet RT-23 Molodets. The United States planned and started development of an analogue, the Peacekeeper Rail Garrison, but abandoned the plan with the end of the Cold War. Similar systems were tested by China in 2016 and North Korea in 2021.
