介绍
45 mm/46 21-K防空炮是一型苏联防空炮,由20-K反坦克炮发展而来,装备于数种苏联舰艇上。
以下载具装备了该武器:
基本信息
可用弹药
- OR-73A:白板高爆弹,爆炸威力低,应尽早换掉
- O-240:研发高爆弹,以初速度大幅下降为代价换取三倍装药量,用于近距离战斗
- BR-240:穿甲弹,在高爆弹无法击穿装甲炮艇和炮塔时可以使用
- F-73:弹底引信榴弹,相当于装药量更高的穿甲榴弹,可穿透船体,对内部模块造成大量伤害

实战中的使用
Much like in real life, the 21-K is horrible at its intended role, anti-aircraft. Its low rate of fire means it is only effective at hitting aircraft when massed, like on Maxim Gorky. On ships with few mounts like Frunze, the 21-K is essentially useless at shooting down aircraft, but it can be used as a weapon against small boats, where its HE shells can be effective at destroying them.
优缺点
优点
- 一发就能击落敌机
- 用高爆和弹底引信高爆打小艇稍微有效
缺点
- 射速很低,防空体验难受
历史
The 21-K is a naval derivative of the Soviet 20-K tank cannon. More specifically, both guns share the same progenitor, the 19-K 45 mm anti-tank gun model 1942, a scaled-up variant of a gun from Rheinmetall. The modification for use as a naval anti-aircraft gun was a simple matter of replacing the carriage with a pedestal mount and giving the gun a semi-automatic breech, though when production began in 1934, only a quarter of the guns had this breech. The early guns were older built-up gun designs, but they would be replaced with monobloc barrels later in production. Because it was semi-automatic, the gun struggled compared to the autocannons used by other nations. It also suffered from not having a time fuse, meaning it could only destroy aircraft with a direct hit. In 1936-37, a new mount for the 21-K was created for use on river monitors called the 40-K along with the 41-K which was a twin-mount. 42 of both mounts were ultimately built. 2,799 guns were built in total from 1934 until 1947, though by 1941 it was largely superseded by the smaller, automatic 70-K as the Soviet Navy's main anti-aircraft gun. In 1942, production was switched to the upgraded 21-KM.
