description Delta A Overview

Delta A was an American expendable launch-vehicle variant in the early Delta rocket family. Introduced in 1962, it retained the basic Thor-Delta architecture while incorporating an upgraded Aerojet main engine, making it an incremental development rather than a completely new rocket. The vehicle belongs to the early space-launch period in which NASA and U.S. industry adapted military-derived propulsion stages for orbital missions.

It illustrates the stepwise evolution of the Delta family.
