Jupiter was originally designed for shipboard use, and adapting a liquid-fuel missile to operate in that environment posed a host of challenges. For example, the Army initially proposed building a missile over 90 feet long, while the Navy wanted a 50-foot missile. After some discussion they compromised on a missile that was 60 feet long and 105 inches in diameter.
