A high-pressure self-sealing obturator positioned to fit on the rear of a bot assembly in a discarding projectile assembly to prevent the obturator from backing off during initial impact of bore walls by the projectile assembly. The obturator includes an extension and a groove for snapping a case mouth into the extension. The outer surface of the obturator conforms with the bore of the gun. The extention of the obturator also includes a "V" groove which permits the separation of the extention with the case mouth during the initial low pressure which occurs early ignition. The self-sealing obturator provides efficient and improved obturation for a projectile when fired from a high pressure gun tube.

A long rod penetrator projectile comprises an elongated main penetrator body, a stabilizing fin assembly attached to the rear of the main body, and a perforated canister carried within the fin assembly. A pyrotechnic material such as pyronol is contained within the canister. The pyronol ignites during impact. The burning pyrotechnic material spews forth through the perforations in the canister to provide improved after armor effects.

A rocket launching cartridge case is formed by attaching a cylindrical extension member to the open end of a cartridge case. The extension member conforms to cartridge receiving chambers of conventional weapons. A rocket assembly is releasably locked within the extension member at a predetermined axial position. The rocket assembly can be slideably positioned within the extension member and locked in place prior to attachment of the extension member to the cartridge case. The locking means establishes a rocket assembly and launching case overall length for use in particular conventional weapons. An obturator member on the rocket assembly engages rifling in the conventional weapon bore imparting a stabilizing spin when the rocket assembly is fired. The obturator is connected to the rocket assembly in a manner permitting slip rotation therebetween providing a predetermined rate of stabilizing spin. The extension member and the obturator have surfaces functioning as gas seals during launching of the rocket assembly.

A cartridge case adapter member is adapted to fit over a fin hub member of fin stabilized projectile and is securely held thereto by the combination of an interlocking retainer sleeve and retainer plug. The combination projectile-to-combustible cartridge case attachment permits the projectile subassembly to pass a standard five foot drop test.

A cartridge assembly for propelling a subcaliber penetrator through a gun tube which has a portion of the propellant charge contained in an annular cavity surrounding the sabot is disclosed. The annular cavity is defined by the scoop shaped front bourrelet, the aft bourrelet which has three radially extending support posts and bore riding shoes, and a combustible tubular case extension over the aft bourrelet extending forward to the front bourrelet. The assembly includes cartridge case having a multistrand ignition system having a plurality of flexible combustible ignition strand. The strands extend through the propellant charge in the case and extend between the posts of the aft bourrelet into the annular cavity to simultaneously ignite the propellant charge contained therein with the portion of the charge in the cartridge case.

The cartridge assembly of the present invention comprises two or more combustible cartridge case segments, the front of which is fastened to the projectile assembly and the rear of which contains a primer assembly and a charge of propellant. The two segments are automatically joined together during loading into a gun chamber via velcro rings at a butted interface between the segments. Extending axially throughout each of the segments is a distributed plurality of flexible combustible ignition strands which, when ignited, propagate the ignition flame front at an extremely high rate, on the order of between 3 to 6 thousand feet per second, ensuring virtually simultaneous ignition of the propellant in each segment.
