Rocket launcher or missile launcher, the wider international term for any weapon that fires a rocket-propelled projectile at a target, is a common name for a device that launches a rocket-propelled weapon which is small enough to be carried by a single person, and fired while held on one's shoulder.
The Miss Launcher is a unique version of the above missile launcher model. It is more comparable to a grenade launcher than a rocket launcher, as it has an arcing flight similar to the Fat Man. Standard missiles fired from this weapon do not fly; instead, the missile-tube itself has been converted to propel them pneumatically. In doing so both the missile's explosive warhead and unused solid rocket fuel are free to detonate together, increasing the missile's explosive damage potential by 30%.
