Rodong-2 (spelled Nodong-2 in South Korea) has been claimed to be a single stage, mobile liquid propellant medium range ballistic missile developed by North Korea. A 2012 paper surveying North Korean missiles published by the RAND Corporation makes no mention of any development or deployment of the Rodong-2, casting doubt that it was ever more than a paper design at most. Joseph S Bermudez of the James Martin Center for Nonproliferation Studies reports that Rodong-2 is an alternative name for the Taepodong-1.
