Special Delivery
The Compression Propulsion System (CPS) is a set of mechanisms made to be retrofitted onto existing firearms. This prevents the waste of disposing of thousands of perfectly good weapons.
![]() Early CPS prototypes were difficult to reload in tense combat situations. |
"The idea was to save money through reuse. The CPS is the perfection of this idea. They didn't want us to change the slingshot -- just what we put in it," stated Dr. Blanchard as she addressed a Congressional sub-committee in December 2003.
CPS uses highly carbonated water as the payload. The carbonation allows the water to achieve the range and force of a conventional bullet. Though the details of the design are still classified, the basic principle is pretty simple.
Water is stored in a tank mounted on the rifle. CO2 is stored in a separate container. When the trigger is pulled, the water is pressurized and blended with the CO2 in the chamber of the rifle. Tiny agitators, called tumblers, spin inside the chamber, further increasing the pressure of the carbonated water. When the soldier releases the trigger, a shudder draws back, freeing the highly pressurized water. Like after shaking a soda can, the liquid explodes out of the chamber. As it is released, the water spirals toward the target thanks to tiny grooves carved into the inside of the rifle barrel. This spiraling action increases accuracy and the concentration of the water stream once it leaves the barrel. The spiraling action also serves to further agitate the carbonated water. In terms of capabilities, the CPS weapons match their conventional counterparts almost exactly. Several military firearms have been modified to create the new hydro-ordnance-capable replacements. The military intends to eventually modify all weaponry to accept a CPS. The tables below list the successful prototypes and their battlefield ratings.
