TheDelta C, orThor-Delta C was an Americanexpendable launch system used for thirteenorbital launches between 1963 and 1969. It was a member of theDelta family of rockets.
The first stage was aThor missile in theDSV-2A (MB-3-II) configuration, and the second stage was theDelta D (AJ-10-118D), which was derived from the earlierDelta.[1] The baseline Delta C used anAltair-2 (X-258) third stage,[1] whilst the Delta C1 had anFW-4D third stage, which provided a higher payload capacity than the Altair. It is unclear whether two or three launches were made using the C1 configuration.
The Delta C was launched fromCape Canaveral Launch Complex 17. Most launches carriedNASA research satellites intolow Earth orbit.[2][1]
