A rocket motor for a gun-fired projectile is configured stiffen the burnable propellant in the rocket motor during burning and/or protect the rocket motor from the pressure that occurs during firing of the projectile from the gun. The rocket motor may include a rigid structure that is integrated into the burnable propellant grain to stabilize the burnable propellant grain during burning of the burnable propellant grain. The rigid structure has a matrix or truss-like shape that extends into the depth of the burnable propellant grain. The rocket motor may include a baffled end cap that covers a nozzle of the rocket motor. The end cap defines a baffled path through the end cap to dampen gas flow into the nozzle and prevent particles of the gun propellant from entering the rocket motor. A rocket motor may implement the rigid structure or the baffled end cap, or both structures.

A serviceable fused battery terminal comprising a disposable fused battery end containing a fuse link, the disposable fused battery end being initially integrated with a cable-connecting portion of the terminal which is secured to an electrical cable, for example by crimping in known manner. When the fuse blows, the battery end is removed from the cable-connecting end by breaking or separating it, while the cable-connecting end remains secured to the cable in its original fashion. A portion of the cable-connecting end is formed as a reattachment point for a replacement fused battery end , which is then secured to the remaining original cable-connecting end to create a new fused terminal. The inventive terminal allows for the easy replacement of blown fuses in the field without having to cut or otherwise remove the cable-connecting portion of the terminal from the cable.
