It was a member of the Delta family of rockets.The first stage was a Thor missile in the DSV-2A configuration, and the second stage was the Delta D, which was derived from the earlier Delta. The baseline Delta C used an Altair-2 third stage, whilst the Delta C1 had an FW-4D third stage, which provided a higher payload capacity than the Altair."@en . "13"^^ . . . "1969-01-22Z"^^ .
