Description
Introduction
The NR-23 is an early Cold War era autocannon of Soviet origin. NR-23 was developed as 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.
Design
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.
Firepower
The NR-23 fires the 23x115mm round from a single belt. Cyclic rate of fire is over 800 rpm. Commonly used ammunition types are armor piercing incendiary (API) and high explosive incendiary (HEI) with impact fuse.
Platforms
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 NS-23 earlier.
