Does anyone remember the Navaho missile?

The booster engine was redesigned to become the engine for the Redstone,
later for the Saturn 1. So this one of Apollo-Saturn ancestors.

Officially, the program was canceled on 13 July 1957, after the first four
launches ended in failure. In reality the program was obsolete by mid-1957
as the first Atlas ICBM began flight tests in June and the Jupiter and Thor
IRBMs were showing great promise. These ballistic missiles however would not
have been possible without the liquid fuel rocket engine developments
accomplished in the Navaho program.
