Lodged projectile removal charge
A process that uses a lodged projectile removal charge (LPRC) apparatus to remove a projectile jammed in a cannon's gun tube. The LPRC is positioned coaxially and offset from the projectile, and the gun tube is filled with water. The charge is detonated producing a shock wave that disintegrates the LPRC apparatus and pressurizes the water. The pressurized water produces a radial hydraulic force against an interior wall of the gun tube, an axial hydraulic force against the projectile pushing the projectile toward the chamber, and produces an opposing expansion of explosive gases that blasts out most of the water in the gun tube. The process is less likely to damage the gun tube. The LPRC may be made using a 3D printer.

Rocket extraction device and method
A rocket extraction device and method is disclosed. In one embodiment, the device comprises an upper and a lower casing; an interior cutout in each of the upper and lower casings, the interior cutouts having contours matching exterior surface contours of a rocket fuze; an upper fuze clamp and a lower fuze clamp disposed respectively within the upper and lower casings, each upper and lower fuze clamp having interior surface contours matching exterior surface contours of the rocket fuze; a clamp adjustment screw onto which the upper fuze clamp is mountable; an adjustment wheel mountable at the exterior end of the clamp adjustment screw by which the clamp adjustment screw and the upper fuse clamp are movable to secure the upper and lower fuze clamps to the fuze and force the fuze into the contours of the lower fuze clamp and the interior cutout of the lower casing to lock the fuze into the rocket extraction device. There is an eyebolt or similar type device mountable to the exterior of the rocket extraction device, to which force is applied to remove a rocket from a storage tube. In another embodiment, the method comprises attaching the rocket extraction device securely to a fuze on a rocket and pulling on the rocket extraction device to remove the rocket from a storage tube.
