Thor DSV-2

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]

Variants

Thor DSV-2C

Thor DSV-2D

The DSV-2D was launched twice in 1962,^[2] 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.^[3] Four launches failed, all of which were carrying live nuclear warheads.^[3] 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,^[4] 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.^[5] 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.^[6] 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.
