Since the Juno I was the same height as the Jupiter-C (21.2 meters), with the added fourth stage being hidden inside the shell, this vehicle which successfully launched the first orbital satellite of the United States is often incorrectly referred to as a Jupiter-C.
Kadangi „Juno I“ buvo tokio paties aukščio, kaip „Jupiter-C“ (21,2 m), o papildoma ketvirtoji pakopa paslėpta apvalkale, šis įrenginys, kuriuo buvo sėkmingai paleistas pirmasis JAV orbitinis palydovas, dažnai painiojamas su „Jupiter-C“.
