The Shipunov 2A42 Sound is a sound of a firing Soviet/Russian 30 mm autocannon. 2A42 has a dual feed. One is for HE-T and the other for AP-T rounds. The gunner can select one of two rates of full automatic fire: low at 200 to 300 rds/min and high at 550 to 800 rds/min.

The BMP-2 mechanised infantry combat vehicle, BMD-2 and BMD-3 airborne combat vehicles and BTR-90 armoured personnel carrier use this gun. The cannon is also the main armament of BMPT (Tank Support Fighting Vehicle). The design bureau for the 30 mm 2A42 cannon is the KBP Instrument Design Bureau.

The Mil Mi-28 is equipped with a chin-mounted NPPU-28 turret with 30 mm automatic Shipunov 2A42 autocannon. Likewise Kamov Ka-29TB, Ka-50 and Ka-52 use it.

The 2A72 30mm autocannon is a lighter, less complex cousin of the 2A42, with a longer barrel.

The Shipunov 2A42 Sound consists of the firing start sound – [START] file, [LOOP] audio file 10 seconds long and the ending file – [END], which should be played at the end of the shooting. The Aircraft Weapons SFX Library includes 51 audio files.
