Abstract: An insensitive munitions (IM) primer for use with major caliber gun systems, including an elongate housing, a tube, an ignition assembly, and a booster assembly. The elongate housing has a proximal end and a distal end. The tube has a first end coupled within the distal end of the elongate housing. The ignition assembly is located within the proximal end of the housing. The booster assembly is located within the elongate housing adjacent the ignition assembly and including a booster holder providing a cylindrical structure defining an internal bore in which a first burst disk resides and is mechanically restrained by a booster disk lock.

Abstract: The present invention is an obturator for a guided projectile. The obturator allows for decoupling the projectile from the rotation of the rifled barrel by use of a static band, a front slip band, a rear slip band and a slip disk. The slip disk is disposed between the front and rear slip bands and allows the rear slip band to rotate independently from the front slip band.

Abstract: Disclosed herein is a test gun barrel for use with a long range projectile testing system. The test gun barrel comprising a main gun barrel and a gun barrel extension. The main gun barrel and gun barrel extension each include a joint end having aligning cylinders and bores to properly align the main gun barrel to the extension prior to engaging threaded coupling. A seal capable of being inspected is made once main gun barrel is fully coupled to gun barrel extension.

Abstract: A substantially nitrocellulose-free insensitive gun propellant for barrel-type weapons is provided. The gun propellant includes at least one nitramine, such as HMX and/or RDX, a second energetic, and an inert binder system. The gun propellant is capable of producing a maximum projectile velocity exceeding 2680 ft/sec when fired from a 5 inch 54 caliber gun and gives a response to slow cook-off insensitive munitions testing of Type 4 or higher, and a response to fragment impact insensitive munitions testing of Type 3 or higher as measured by STANAG 4382 and STANAG 4496, respectively. Also provided is an ammunition round assembly, and an armament system.

Abstract: The invention provides an improved propellant system for firing projectiles in large caliber guns. Strips of energetic propellant are placed in the cartridge case so that the lengths of the strips are parallel to the length of the cartridge. Preferably, the strips are placed in a radially symmetric pattern. The strips provide passageways that allow ignition gasses to flow radially in the cartridge case and along the length of the cartridge case.
