Abstract: A Handle and Firing Mechanism Assembly (H&FMA) provides a robust and streamlined H&FMA for a mortar weapon system. The H&FMA is easier to assemble and eliminates jamming issues, and firing pin protrusion adjustment procedures. It also incorporates a lighter trigger squeeze in Trigger fire mode and locks the firing pin in Drop fire mode. The handle is easier and more cost effective to produce. The H&FMA can be used with, for example, a 60 mm mortar weapon system.

Abstract: A counter momentum generator is employed on a weapon system to manage horizontal recoil momentum of the weapon system. The counter momentum generator generates a counter momentum which that is not parallel to the recoil momentum. A horizontal component of the counter momentum negates a portion of the horizontal recoil momentum. A vertical component of the counter momentum combines with the vertical recoil momentum to aid in compression between the base of the weapon system and the ground.

Abstract: The rifle system comprises a rifle and an ammunition round for operation with the rifle. The high pressure ammunition round further comprises a cartridge case having an outer wall wherein prior to firing of the ammunition round, the outer wall geometry of the cartridge case is devoid of features configured for interfacing with a mechanical extractor. The rifle further comprising a barrel chamber which fully supports a chambered cartridge case and a rear extraction mechanism for extracting a spent cartridge case through the rear of the barrel chamber.

Abstract: One example is test system for testing the propulsion system(s) of vehicles. The test system includes a retention fixture, a linking device, a test logic, a measurement device and a result logic. The retention fixture is for rigidly mounting first and second vehicles to the retention fixture. The linking device links propulsion systems of the first and second vehicles so that the propulsion systems operate a different rates. The test logic subjects the second vehicle's propulsion system to a propulsion test. The measurement device measures at least one parameter associated with the propulsion system of the first vehicle while the first vehicle is subjected to the propulsion test. The result logic determines if the first vehicle under test passed the propulsion test based, in part, on the at least one parameter and generates an indication if the first vehicle passed or failed the propulsion test.

Abstract: Methods of fabricating optical lenses and mirrors, systems and composite structures based on diffractive waveplates, and fields of application of said lenses and mirrors that include imaging systems, astronomy, displays, polarizers, optical communication and other areas of laser and photonics technology. Diffractive lenses and mirrors of shorter focal length and larger size, with more closely spaced grating lines, and with more exacting tolerances on the optical characteristics, can be fabricated than could be fabricated by previous methods.

Abstract: A medium caliber high kinetic energy round with tracer and self-destruct mechanism having an optimized kinetic energy projectile incorporating a fully hardened projectile body and an explosive self-destruct mechanism for a medium caliber high rate of fire round. The medium caliber high kinetic energy ammunition round incorporates a multiple piece sub-projectile that integrates a tracer and high explosive self-destruct mechanism to neutralize the penetrator during self-destruct and minimize collateral damage during firing.
