Alternative use of launchers

IRBMs are frequently turned into small satellite launchers via the addition of (usually multiple) upper stages. In the United States, this happened to both the Thor and Jupiter. A derivative of the Jupiter, the Jupiter-C launched the U.S.'s first satellite, Explorer 1.

Examples include:

• Thor
• Redstone
• Jupiter IRBM
• Shavit
• Taepo Dong 2
• Pluton
• Hades
• SM-64 Navaho (cancelled)
