ASP M78到底是一种什么炮弹

在海武上看美国的3英寸MK27炮的备弹里看到了ASP M78这发炮弹,弹头重13磅,装药量0.77磅,初速度818m/s,生产商应该是挪威的nammo raufoss A/S。看名字像是一种穿甲弹,但是除了上面的数据之外找不到任何其他资料,生产商官网上也没看到相关介绍,应该是已经停产了,很好奇这个炮弹到底是什么样的,装药的化学成分是什么,不知道有没有大佬知道呢?

所以说要么是没公开,要么是资料丢失了?

Development
The 76 mm M78 Anti-Ship Projectile (ASP) was developed and qualified between 1976 and 1978 by Raufoss Technology A/S (now Nammo Raufoss AS), using programmes co-ordinated by the Royal Norwegian Navy. Production was carried out between 1981 and 1984. The projectile has the same interior and exterior ballistics as other rounds fired by the US 3 in/50-calibre cartridge for the 3 in/50 Mk 27 naval gun. This gun has now mainly been withdrawn from Norwegian service and further production is unlikely. Some of the naval gun mountings were used in coastal defence roles after been withdrawn from warships.
The main requirements of the 76 mm M78 ASP were these:

[*]penetration of steel plates used for ships' hulls
[*]a delay feature to permit functioning after target penetration
[*]optimum destructive effect to be delivered approximately 2 to 4 m inside the target
[*]terminal effects including blast, fragments and an incendiary element.

Description
The 76 mm M78 ASP is part of a fixed round, with the projectile rigidly secured to the Mk 7 necked brass cartridge case by 360º crimping rings.
The ASP M78 projectile has a forged alloy steel body filled with 350 g of Composition A-3. Threaded into the neck of the body is a penetrator cap containing the rear fuze assembly which includes the delay element, the safety/arming mechanism and a booster. A Point-Detonating (PD) front fuze is mounted at the tip of a streamlined windshield which covers the front of the penetrator.
As the front fuze strikes a target, it functions to initiate a pyrotechnic train to the rear fuze, in which a 5 ms delay is introduced before the main charge detonates.
The Mk 7 brass cartridge case contains 1.8 kg of M6 propellant. Priming is electrical. The muzzle velocity is 823 m/s, and the maximum range 12,930 m.
The front fuze will function on striking 1.25 mm steel plates set at an angle of 0º. The projectile will penetrate 20 mm armour steel plates set at an angle of 45º and function after penetration.
Armament
76 mm '3 in/50' naval and coastal-defence guns.

76毫米M78型是由劳福斯技术工程公司(现在的劳福斯-北欧弹药公司)在挪威王家海军的提案下,于1976至1978年研制成功的反舰炮弹(ASP)。炮弹的生产于1981至1984年间进行。该炮弹的内外弹道与美国3英寸/50倍径Mk 27型舰炮所使用的其他炮弹相同。Mk 27型火炮目前已经从挪威海军退役,炮弹也不太可能继续生产。一部分此型号火炮从军舰上拆下后被用于海岸防御。

76毫米M78型反舰炮弹的基本性能要求如下:

1、能够穿透船体用钢板

2、要具备延时爆炸能力,即在穿透目标起爆。

3、穿透目标后,在深处2至4米爆炸为最佳。

4、起爆后能够产生破片、冲击、燃烧等破坏效果。



76毫米M78型炮弹为定装弹,其弹头通过一个360°卷制的金属环与Mk 7型缩颈式黄铜弹筒刚性固定在一起。

M78型炮弹的弹头为锻造合金钢制,填充有350克A-3炸药。被帽被拧入弹头颈部,被帽中含有后引信组件,该组件包括延时元件、保险装置和助推剂。点引爆(FD)前引信安装在风帽尖端。

当前引信击中目标时,它的作用是向后激活后引信的延时程序,延时引爆主装药的时间为5毫秒。

Mk 7型弹筒装有1.8千克的M6发射药。电击发。(炮弹)初速为823米/秒,最大射程为12930米。

前引信的击发条件为0°撞击1.25毫米厚的钢板。M78型炮弹可以在45度着角的状态下,击穿20毫米厚的装甲板。穿透后即可爆炸。

适用火炮

76毫米(3英寸/50倍径)舰炮/海防炮。
