The earliest Agena variant was the Agena A in 1959–60, which did not have restart capability, mostly flown on Thor-Agena boosters for the Discoverer program.. The early Atlas LV3 Agena A variant was flown four times for the Midas and Samos programs (Midas 1, Midas 2, Samos 1, and Samos 2), with two failures.

The first Agena-D launch was of KH-4 #7 on June 28, 1963, and a total of 269 Agena-Ds were launched. The Agena-D was used to launch KH-7 GAMBIT and KH-8 Gambit 3 reconnaissance satellites, three Mariner probes to Venus and the two Mariner space probes to Mars. Thor-Agena flew for the last time in 1972 when it launched a KH-4B satellite.
