Fire from the eight machine guns of a Hawker Hurricane is shown converging to a point, then diverging. (Drawing not to scale.) In aerial gunnery, gun harmonisation, convergence pattern, convergence zone, convergence point or bore-sight point refers to the aiming of fixed guns or cannon carried in the wings of a fighter aircraft.
The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun, and allowed an airgunner in an open cockpit to swivel and elevate his weapon (a Lewis machine gun) quickly, and easily fire in any direction. Later models permitted the fitting of two Lewis guns; while this doubled the firepower available ...
It is designed to mount on a variety of vehicle platforms and supports the Mk 19 grenade launcher, 12.7 mm M2 .50 Caliber Machine Gun, 7.62 mm M240B Machine Gun, and 5.56 mm M249 Squad Automatic Weapon. The system is composed of two parts: the mount which is fixed to the exterior of the vehicle and the control group.
Figure 1: Rangekeeper Coordinate System. The coordinate system has the target as its origin. The y axis value range to the target. US Navy rangekeepers during World War II used a moving coordinate system based on the line of sight (LOS) between the ship firing its gun (known as the "own ship") and the target (known as the "target").
An air gunner or aerial gunner is a member of a military aircrew who operates flexible-mount or turret-mounted machine guns or autocannons in an aircraft. [1] Modern aircraft weapons are usually operated automatically without the need for a dedicated air gunner, but older generation ( World War II and earlier) bombers used to carry up to eight ...
Casemate-mounted 5"/50 caliber gun on the USS North Dakota. A casemate is an armoured structure consisting of a static primary surface incorporating a limited-traverse gun mount: typically, this takes the form of either a gun mounted through a fixed armour plate (typically seen on tank destroyers and assault guns) or a mount consisting of a partial cylinder of armour "sandwiched" between ...
The gun mount moves at a very high speed and with great precision. The system takes minimal inputs from the ship, making it capable of functioning despite potential damage to the ship. The only inputs required for operation are 440 V AC three-phase electric power at 60 Hz and water (for electronics cooling).
