The Thor DSV-2 was a series of sounding rockets, test vehicles, and anti-satellite weapons derived from the Thor Intermediate-range ballistic missile. It was also used as the first stage of several Thor-derived expendable launch systems.[1][2]
Thor DSV-2A
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]

Thor DSV-2D
The DSV-2D was launched twice in 1962,[4] conducting suborbital research flights for the development of the Program 437 ASAT. It was a single-stage vehicle, consisting of a Thor DM-21. Launches were conducted from Cape Canaveral Air Force Station Launch Complex 17A.

Thor DSV-2E
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.

Thor DSV-2F
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 Station Launch Complex 17B.

Thor DSV-2G
The DSV-2G was a two-stage rocket, consisting of a Thor DM-19 first stage, and a Delta second stage. Three were launched between 1964 and 1965 as part of Project ASSET.[7] Launches were conducted from Cape Canaveral Air Force Station Launch Complex 17B.

Thor DSV-2J
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.
