The DSV-2A was a two-stage rocket, consisting of a DSV-2A / MB-3-II first stage, and an Able-Star / AJ10-104D second stage.[3] It was launched eight times between 1963 and 1965 from Vandenberg.[3]
The DSV-2E was a single-stage vehicle, using a Thor DM-19. It was launched eight times in 1962, including several nuclear weapons tests as part of Operation Fishbowl.[5] Four launches failed, all of which were carrying live nuclear warheads.[5] Launches were conducted from Launch Emplacements 1 and 2 on Johnston Atoll.
Radar contact lost 5 minutes after launch. RSO destruct command sent.

RVs caused turbine exhaust gas to enter the thrust section, overheating and weakening the engine mounts. Engine broke loose and ruptured the propellant tanks T+59 seconds. Warhead destroyed by RSO T+65 seconds.
Stuck LOX valve caused loss of thrust and fire on the launch stand. Range Safety Officer destroyed the missile and warhead. Launch area extensively contaminated with plutonium.
The DSV-2F was a single-stage vehicle consisting of a Thor DM-19, like the DSV-2E. Three were launched between 1963 and 1964, as part of Project ASSET,[6] which involved launching a sub-scale mockup of the X-20 Dyna-Soar to test materials for the larger spacecraft. Launches were conducted from Cape Canaveral Air Force StationLaunch Complex 17B.
The DSV-2J was an operational nuclear anti-satellite weapon. 18 were launched between 1964 and 1975.[8] Most flights were non-intercept tests of the rocket's anti-satellite capabilities, however some later launches carried research payloads. Launches were conducted from Launch Emplacements 1 and 2 on Johnston Atoll.
