There were some weird fucking Delta II derivatives planned
>7930
Used a cryogenic upper stage with an RL10 instead of its then-current hypergolic one. Core stage is unchanged
>Wide-Body Delta II
This was something of a precursor to the Delta III. Used a 4 meter fairing. It also used a 3.2 meter wide cryogenic upper stage, which necessitated a 3.2 meter wide expansion to the core stage’s kerosene tank.
This would appear on the Delta III, but with 4 meters all the way down except for the core stage’s lox tank.

>Double Barrel Deltas
Used a pair of “normal” Delta II cores in unison to make the oddest looking rocket ever.
