The 7.62 mm ShKAS (Shpitalny-Komaritski Aviatsionny Skorostrelny or Shipitalny-Komaritski rapid-fire for aircraft – Russian: ШКАС - Шпитального-Комарицкого Авиационный Скорострельный) is a 7.62 mm calibre machine gun which was first produced in 1933 for usage in Soviet aircraft which saw action all the way through World War II in many of the fighters, attackers and bombers of the day. The ShKAS is a single chamber, gas-operated revolver-type machine gun in which a firing pin strikes the primer of the bullet in the chamber to fire the round.

General info

With 1,800 RPM, the ShKAS has the highest rate of fire of any machine guns in World War II. Aside from the default ball and plain tracer rounds, the ShKAS's common round composition involves the API-T, API, and AI rounds. Due to the ineffectiveness of the AI rounds due to tiny explosive filler, uses of belt with only the API-T and API are recommended as both rounds has a high chance of lit up the enemy plane on fire if enough shots were hit.

Usage in battles

The ShKAS are one of the more powerful .30 cal machine guns in the game, only the rotary M134 Minigun and GShG-7.62 surpass it in terms of raw firepower for its calibre. However, it is still held back by the common impotence of small-calibre guns, along with its tendency to jam, thus making trigger discipline vital to its success.

Due to its superior ballistic properties and ammunition compared to other similar guns, the ShKAS is an easy-to-use weapon for beginners. As plenty of early Soviet planes were equipped with this machine gun, this allows the newcomer to learn how to utilize these weapons for various purposes. Though be sure to fire it only in short burst as the gun can be jammed easily, and only fire them for ranging or when you're sure that the shot will land on target.

In some higher tier planes equipped with the ShKAS, the ShKAS's small calibre rounds will started to show its age, as the round has very low damage compared to the more abundant .50 cal machine guns or 20 mm autocannons, though it remains deadly against pilot and internal modules if enough shots land. The gun also has a use against ground targets and slow-flying AI aircraft, in which the ShKAS can take them down with a few shots, allowing the player to conserve more valuable autocannon rounds for enemy planes while earning extra points from destroying AI targets.

Pros and cons

Pros:

  • The fastest firing rifle-calibre machine gun in WWII
  • High shell velocity, only small leads are needed while aiming
  • Very accurate at short-to-medium range (~800 m), ideal for attacking ground targets and AI aircraft
  • Every belt is extremely effective at causing fires on enemy aircraft (tracers and stealth are the most effective)
  • Incredibly easy to knock out gunners and pilots on enemy aircraft (or exposed crew members on ground and naval forces)
  • If fired in short bursts, most aircraft can make a belt last an entire game in realistic battle

Cons:

  • Accuracy and penetration drops off at longer ranges (beyond 1 km), restricting it to close range weapon
  • Can easily jam. It is recommended to fire in bursts lasting no longer than one second
  • Limited damage output due to small shell size, thus requiring multiple hits to knock out the target. This is especially apparent on the defensive version where enemy has more chance to dodge it

History

A diagram of the operation of the ShKAS (7.62 mm) machine gun with identification of parts.

The 7.62 mm ShKAS machine gun is a Soviet .30 calibre machine gun designed by Boris Shpitalniy and Irinarkh Komaritsky for use on Soviet aircraft. It was designed in 1932 and entered service a year later.

The designers departed from traditional methods of feeding belt linked ammunition into the ShKAS and utilised a feed design nicknamed "bird-cage" or "squirrel-cage".[1] Even declassified documents regarding the United States' evaluation of the feed system stated, "…an interesting departure was made from the heretofore orthodox practice of feeding ammunition to a gun of this caliber [sic]." [2]

The ammunition belt enters the feed cage forward of the firing chamber. When the gun is fired, a gas piston actuates an arm connected to the cylindrical feed cage, rotating it one position to introduce the new bullet. As the feed cage (holding ten rounds) rotates a helical groove and guides the bullets rearward. Through this process of working the bullets rearwards, they are automatically delinked from the metal disintegrating link belt. The rounds make it to the final position at the bottom of the drum where they are then chambered into the receiver, ready to be fired.

One of the benefits of this feed system is during the camming of the rounds; there is relatively no drag on the ammunition allowing the gun to be fired at high rates of speed; however, prolonged actuation can provoke these guns to jam. Rates of fire could be regulated through changing of the holes in the gas regulator, three different hole sizes going from largest to smallest would slow down the rate of fire to a more moderate rate.

The ShKAS machine gun had a high rate of fire but it also had 48 ways of jamming. Some of them could be fixed immediately, some could not. And 1,800 rounds a minute was an insanely high rate of fire. If you pulled the trigger too long, the ShKAS would fire all its ammo in one go and that would be it!![3]

— Viktor M. Sinaisky - Soviet machine gun technician

By the end of World War II, over 150,000 ShKAS had been produced. The gun can be found on a wide range of Soviet aircraft, across fighters, attackers, and bombers. The gun also saw service in the Spanish Civil War with the Republican Spanish forces, as well as the Second Sino-Japanese War and the subsequent resumption of the Chinese Civil War on both the Nationalist and Communist Chinese sides.
