GSh-23L (23 mm)

Description

The GSh-23L is a twin-barreled aviation autocannon that was introduced in Update 1.81 "The Valkyries". Featuring a very high rate of fire, the GSh-23L is the developmental follow-on to the Nudelman-Rikhter series of autocannons and was first introduced in 1965. The weapon operates on the Gast principle, whereby the recoil from one barrel operates the mechanism of the other, providing an inexpensive and simple method of a high rate of fire weapon without resorting to revolver or Gatling mechanisms. The GSh-23L is found on both helicopters and fixed-wing aircraft and provides these vehicles with very accurate and deadly firepower. Featuring nearly 3,400 rounds/minute and very limited ammunition choices, this cannon performs the job it was made to do without any unnecessary complications, although it will take discipline to not expend all of the ammunition in waste.

Comparison with analogues

• NR-23 (23 mm): The GSh-23L is a direct developmental replacement for the NR-23, featuring a vastly better rate of fire although it uses the same ammunition.
• NR-30 (30 mm): The NR-30 has far more explosive power due to the larger shells, although it only has a fire rate of 1,000 rounds/minute.
• GSh-23-2 (23 mm): This is used in the UPK-23-250 gun pod on a wide variety of helicopters and aircraft, but has a much lower rate of fire.
• GSh-30-2K (30 mm): The GSh-30-2K operates on the same principle and has a very high rate of fire (~2,600 rpm) but has better performance due to being 30 mm calibre.
• M61 (20 mm): The M61 cannon has comparable explosive filling to the fragmentation rounds of the GSh-23L, although the M61 has improved ballistics and an astounding 6,000 rounds/minute rate of fire.
• M197 (20 mm): The M197 uses the same ammunition as the M61, although it has a far lower rate of fire at 1,000 rounds/minute. Compared to the GSh-23L, it has a greater ammunition capacity on helicopters (750 vs 450 rounds).
• GIAT M781 (30 mm): The M781 is another helicopter-mounted cannon, and although it has much more offensive power than the GSh-23L it lacks the rate of fire at only 1,200 rounds/minute.

Pros and cons

Pros:

• Much higher rate of fire than previous cannons
• Powerful fragmentation rounds which can cause severe damage to enemy aircraft

Cons:

• Very limited ammunition choice (only AP-I and FI-T shells available)
• Small amount of ammunition available on fixed-wing aircraft
