A launcher for launching a projectile includes a launch piston for engaging and driving the projectile from the launcher and a launch brake that constrains the piston to enable separation of the piston from the projectile. The launch brake is configured to have minimal to no effect on projectile exit velocity and exit trajectory from the launcher. The launch brake is also configured to reduce the velocity of the launch piston via coupling of the masses of the launch piston and the launch brake. The coupling allows, separation of the projectile from the launch piston and reduces or prevents a negative effect on stabilization of the projectile upon exit from the launcher.

The present invention relates to a multi-section barrel, fluid-propelled spinning ammunition, as well as a weapon system formed by them. The multi-section barrel adjusts the interaction between barrel and projectile through barrel shape to improve range and precision; the fluid propels the self-selected projectile to guide the fluid through and twist the projectile by arranging volute holes or volute grooves at the rear or tail of the projectile, so that the projectile forms spin through the action of the fluid without relying on rifling; the projectile can be used in combination with multi-section barrel, which can improve performance and reduce cost simultaneously.

A light weight shoulder fired projectile weapon is shown which could be used against multiple target sets. The accurate and consistent muzzle velocity needed for these multiple purposes is accomplished through accurate and consistent gun chamber pressure. A shot start feature integrated with sabot sections on the projectile consistently holds the projectile in place in its launch tube until the consistent chamber pressure is reached.
