impart a considerable forward velocity to the actuating slide to start counter-recoil. Ammunition may be fed from either the left or from the right side. Fired cartridge cases are ejected through a port on the underside of the receiver and empty belt links drop out of the feed mechanism at the opposite side from which the belt was fed. A pneumatic charging mechanism is used to charge the cannon and to clear misfires.

extract the fired cartridge case. The lower lever protrudes into the weapon housing and has a U-shaped recess on its lower end. As the actuating slide moves back and forth, a lug in the weapon housing is cammed into this recess to guide the chambering levers. The 12.7mm A-12.7 aircraft machine gun and the 23mm ZSU anti-aircraft gun are essentially identical in design and operation.

The AM-23 aircraft cannon is a gas-operated weapon with a vertically moving wedge breechblock. Two jointed chambering levers are pivoted from the actuating slide. The upper, longer lever is used to ram the cartridge from the belt link into the chamber. An extraction claw on its forward end is used to

bomber was in most versions equipped with a total of six AM-23 cannon located in three defensive turrets. Later, the tail turret of the Tu-95 was completely replaced by an electronic countermeasures installation, which resulted in the Tu-95MS. Apart from the Tu-16 and Tu-95, the AM-23 cannon was also

The AM-23 differs from the ZSU anti-aircraft cannon in having a gas buffer where the ZSU has a disk spring buffer. The propellant gas conducted into the buffer is used to soften the impact of the actuating slide when it reaches the back plate. The compressed gas inside the buffer is then used to

Although NS-23 and AM-23 ammunition is dimensionally the same, it is not permitted to fire NS-23 and NR-23 ammunition in the AM-23 or GSh-23. However, AM-23 ammunition can be fired safely in the NS-23 and NR-23. To instantly distinguish AM-23 cartridges from the NS-23 ammunition, the AM-23

The Tu-16 bomber was armed with a total of seven AM-23 cannon. A single cannon was fixed in the nose of the aircraft, and the others were mounted in pairs in the defensive turrets. The
