NSN:1305-50-000-0720
The Rounds are compatible with 23 mm ADS, ADS-N, ZU-23-2, ZU-23-2F and ZSU-23-4 and intended to defeat air targets, ground unarmored and light armored vehicles and manpower.
Ungraded all-weather fuze AF22:
- Features the same sensitivity upon impact on solid surface as AF21 (e.g. cardboard, wood, duraluminium, steel, etc.),
- It is provided with better moisture protection in comparison with fuze AF21, however it does not detonate upon collision with raindrops.
