大和在萨马海战对白平原的近失弹威力,为什么凭借460mm的世界最大主炮,打出1-2发很近的近失弹(以前看到一张照片,上面有两发近失),为什么仅仅震坏了右舷机舱?最近仔细看了学研的《长门型战舰》一书,里面记载了原因,因为日本舰队先发现的是美国飞机,而后发现美国舰队之后几乎是立刻就开火射击了,所以大和、长门两舰的前两次齐射使用的是对空射击用的三式弹!而众所周知,三式弹是一种燃烧弹,既不是穿甲弹也不是高爆弹。 
这个三式弹出膛约1000米爆炸开,散射出900个燃烧管,形成一个小燃烧弹幕。
那么前两次齐射是不可能伤到什么军舰了。因为当时没有美舰在大和几千米距离内。
As were most Japanese warships, the Yamato and Musashi were provided with a special anti-aircraft incendiary shrapnel shell officially designated as "3 Shiki tsûjôdan" (Common Type 3) and supposedly nicknamed "The Beehive," but this could be apocryphal. This round weighed 2,998 lbs. (1,360 kg) and was filled with 900 incendiary-filled tubes. A time fuze was used to set the desired bursting distance, usually about 1,000 meters (1,100 yards) after leaving the muzzle. These projectiles were designed to expel the incendiary tubes in a 20 degree cone extending towards the oncoming aircraft with the projectile shell itself being destroyed by a bursting charge to increase the quantity of steel splinters. The incendiary tubes ignited about half a second later and burned for five seconds at 3,000 degrees C, producing a flame approximately 5 meters (16 feet) long. |
