An electrically driven rotary machine gun includes a drive motor, a feeder delinker, a clutch, and a gun control unit. The drive motor is configured to rotate a rotor of the gun when receiving power. The feeder delinker is configured to provide ammunition cartridges to the rotor while being rotated. The rotor fires the ammunition cartridges while receiving them from the feeder delinker and being rotated by the drive motor. The clutch is configured to selectively engage the rotor and the feeder delinker while actuated. The gun control unit is configured to receive input from a user and provide power to the drive motor as a function of the input received from the user while and to actuate the clutch while providing power to the drive motor. The gun control unit includes a battery to eliminate the necessity of an external power supply.

A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.

A gun control unit for a M134 minigun firearm including an armature and a stator comprising at least one hardware processor; and one or more software modules that are configured to, when executed by the at least one hardware processor, independently control the armature; independently control the stator.

Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.

A breech block assembly for a firearm includes a guiding element having a slide adapted to slide along a guide in an actuation system of the breechblock assembly driven by a motor. A shutting element shuts an opening in a breech ring of the firearm. A percussion pin is pushed by an elastic element slide along a longitudinal axis, as a function of the firing cycle of the firearm to an axial hole in the shutting element. The percussion pin is shaped to partially come out of the axial hole of the shutting element for firing a piece of ammunition. The breechblock assembly comprises a control system for controlling the percussion pin. The control system controls the operability and the movement of the percussion pin independently of a firing cycle of the firearm.

A weapon system that includes a breechblock, which is formed at least by a breechblock carrier and a breechblock head, the breechblock carrier being designed so as to carry the breechblock head. To achieve the fact that forces acting upon the breechblock drive during the unlocking of the breechblock and the withdrawal of a cartridge casing are minimized or even eliminated, the breechblock head is freely movable relative to the breechblock carrier. To separate the breechblock with a breechblock drive of the weapon system during the recoil of the recoiling masses of the weapon system, a device is designed in such a way that a mechanical separation takes place between the breechblock and the breechblock drive during the recoil of the recoiling masses of the weapon system. During the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is reestablished via the device.

A weapon system having a breechblock, wherein the breechblock can be mechanically connected to a drive of the weapon system. The weapon system comprises means which are designed in such a way that a mechanical separation occurs between the breechblock and the breechblock drive with the recoil of the recoiling masses of the weapon system. With the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is re-formed.
