The Delta C, or Thor-Delta C was an American expendable launch system used for thirteen orbital launches between 1963 and 1969. It was a member of the Delta family of rockets.
Configuration
The first stage was a Thor missile in the DSV-2A (MB-3-II) configuration, and the second stage was the Delta D (AJ-10-118D), which was derived from the earlier Delta. The baseline Delta C used an Altair-2 (X-258) third stage, whilst the Delta C1 had an FW-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.
This template lists historical, current, and future space rockets that at least once attempted (but not necessarily succeeded in) an orbital launch or that are planned to attempt such a launch in the future
Symbol indicates past or current rockets that attempted orbital launches but never succeeded (never did or has yet to perform a successful orbital launch)
