Despite the high characteristics of the YakB-12,7 machine gun, he did not fully suit the army Aviation. Gradually came to the thought of the need to equip the Mi-24 30-mm automatic gun GSH-ZOK. But the mass and recoil force during firing did not allow its placement in the USPU-24 installation instead of a machine gun. The GSH-ZOK was mounted motionless in the U-280 installation on the starboard side of the helicopter, and the combat button was placed on the pilot's control handle.

In 1975, the tests of the Mi-24P helicopter (product 243) began, which, due to the refinement weapons dragged on for more than five years. Only in April, 1981 g. Cannon modification launched into mass production. The subsequent operation of the machine revealed a lack of efficiency and limited application of the fixed gun.
Experience has shown that it is much more rational to use a mobile cannon-mount NPPU-24 (9А-4454) with an 23-mm double-barreled gun GSH-23Л. The helicopter, equipped with this installation, received the designation Mi-24VP (product 258). Compared to the machine gun USPU-24, the firing sector in the horizontal plane did not change, but the vertical deflection of the barrels became possible in the range from + 10 ° to - 40 ° (previously from + 2 ° to - 60 °). The mass of the installation did not change, but the rate of fire was reduced from 5000 to 3400 shots / min.
