NR-23 was developed as a more reliable and faster firing successor for the earlier NS-23, which it replaced on the production line. The NR-23 design as also scaled up, resulting in the NR-30. For a number of years the NR-23 was the main type of cannon armament installed in both fighters and bomber aircraft.

The NR-23 was used in later models of the MiG-15 and Yak-17, which used the NS-23 earlier. The NR-23 is a further development of the NS-23. Reliability was improved and NR-23 has the ability for either left or right hand feed.

The short recoil mechanism was rearranged in order to provide for a higher rate of fire. Barrel length and overall dimensions were kept similar to the NS-23, to allow for easier upgrade of existing MiG-15 and Yak-17 designs.

The VYa cannon were made on two #2 and #66 plants. In 1942 it has been made 13420, in 1943 - 16430, in 1944 - 22820, in 1945 - 873, in 1946 - 2002 and in 1947-1247 pieces.
