Description

The Gryazev-Shipunov GSh-30-1 autocannon (GRAU 9A-4071K), aka Type 30-4 after reverse-engineered by CSGC Xi'an Kunlun Industry, is currently the most common 30 mm single-barrel autocannon used by Soviet/Russian jets and their PLAAF derivatives. With its high caliber for its era, enemy jets will face very severe damage from short bursts from GSh-30-1.

Comparison with analogues

GSh-30-2 - The Gast-principle 30 mm autocannon for Su-25 series or post-Mi-24P helicopters; having almost double RoF while maintain similar firepower.

GSh-6-30 - The rotary (Gatling) 30 mm autocannon exclusively for MiG-27 series at almost tripled RoF but with similar firepower.

Mauser BK27 - German revolver at similar RoF while having slightly higher penetration.

Usage in battles

The designer duo V. Gryazev and A. Shipunov, who could be said as the most well-known autocannon designers of Soviet Union, developed the GSh-30-1 to replace previous NR-30 developed way back in 1950s; thanks to the well refined design of GSh-30-1 and its short-recoil action, it can achieve sufficiently high than all its predecessors in Soviet service (for comparison, NR-30 is topped at 1000 RPM while GSh-30-1 can go up to 1500-1800 RPM) albeit slower than most of its competitors in NATO services with rotary cannons. While the damage is more than enough to tear down enemy jets with a short burst, be sure to make every ammo counts as the gun only has at most 150 shells, sometimes even lower such as Yak-141 with only 120 shells; utilizing the radar (both radar and IRST) or HMD is a good idea to maximize efficiency as it can calculates the trajectory of cannon against designated targets.

Pros and cons

Pros:

  • Devastating firepower against enemy aerial targets
  • Sufficient penetration for occasional ground-attack operations

Cons:

  • Low ammo pool (up to 150 shells)
  • Relatively less RoF than Gast/rotary autocannons (i.e. GSh-30-2; M61A1)

History

Soviet Union has been an user of 30 mm caliber autocannons for decades since 1950s with their introduction of NR-30 for MiG-19 series; while the gun has been proved reliable, debates for the existence of autocannons onboard interceptors were also a major consideration during the development of MiG-29 and Su-27 series to further reduce weight. The NR-30 was too large to be fitted into the fuselage while the "smaller caliber" GSh-6-23 rotary cannon is also too large for both aircraft (which was the gun for MiG-31), thus Vasily Gryazev and Arkady G. Shipunov cooperated yet again for a compact gun with higher RoF; the newly-developed GSh-30-1 completed its development in 1977 and were installed on the aforementioned jets as their spare weapon (Note: according to tests, the barrel life is only at 2000 rounds while continuous fire and emptying the ammo chamber will further reduce its life).

Excellent additions to the article would be video guides, screenshots from the game, and photos.
