A grenade launcher apparatus having an integral fire control system includes a receiver having a fore end portion, a pivotally attached to the fore end portion, the barrel having a muzzle end and a breech end. A trigger assembly is coupled to the receiver adjacent the breech end of the barrel and a hand grip is attached to the receiver adjacent the trigger assembly. A buttstock assembly is coupled to the receiver and a fire control system secured to the fore end portion of the receiver. In another aspect, a fire control system is provided. In yet another aspect, a method aiming a grenade launcher apparatus is provided.

An unmanned flying grenade launcher system is provided. The unmanned flying grenade launcher can include a portable unmanned aerial vehicle with an attachment apparatus configured to receive a standardized grenade launcher, and a servo coupled to adjust the angle of the grenade launcher relative to the portable unmanned aerial vehicle downward relative to the unmanned aerial vehicle. One or more telemetry systems can provide a visual indication of the unmanned aerial vehicle's surroundings to an operator, and can receive flight commands and firing commands from the operator such that a firing mechanism fires the standardized grenade launcher in response to the firing command.

A baffled ram accelerator system includes a ram accelerator tube with an inner surface and an outer surface and a plurality of baffles disposed on the inner surface. The plurality of baffles forms a sequential series of propellant chambers along the longitudinal axis of the ram accelerator tube. An accelerator gun is also disposed on an input end of the ram accelerator tube, and the accelerator gun is positioned to fire a projectile into the ram accelerator tube.

A cartridge casing having an open neck at one axial end and a closed rear portion at the other axial end to form an interior cavity for propellant. A projectile within the open neck to seal the cavity so the bullet is released when the propellant is primed and ignited. The projectile has a proximate end releasably secured within the neck of the casing facing the cavity and exposed to the forces generated by ignited propellant. The remote end of the projectile is formed by a lead core while the proximate end has a transverse surface and is at least partially formed of an amorphous metallic alloy having properties of bulk metallic glass (BMG). Liquid metal alloy can also be used at the interface of a propellant chamber in a bore of a cannon and a cartridge-free projectile.

A digitally controlled mobile ground launching fire retardant delivery system. The system is configured to launch fire retardant projectiles at wildfires located in a small fire area that is considered inaccessible by fire personnel, due to the terrain, elevation and/or remote location. The system is also advantageously configured to launch soft-ball size objects at remote wildfires. The soft ball sized objects will contain at least one beneficial fire-retardant substance contained therein.
