Astro IV
Orbital launch vehicle. Year: 1959. Country: USA. Status: Study 1961.

A two-stage all-Lox/LH2 vehicle proposed for the USAF SLV-4 requirement. Ruled out because it did not use the large segmented solids then favored by the USAF and its think tanks.

The design apparently used five J-2 engines in the first stage, and a single J-2 in the second stage.
