长身管化的历史最早投入战场使用的坦克是一战时期的英国Ⅰ型坦克,该坦克分为两种类型,一种是安装了机枪的“雌性”坦克,另一种是安装火炮的“雄性”坦克。“雄性”坦克上的火炮原为英国海军的舰炮,口径57mm,身管长度为40倍口径。此后直至二战初期,该炮的口径和长度一直保持着世界纪录。增大火炮口径和增加身管长度必然会提高火炮的威力,这是不言自明的道理。然而自坦克问世之后的一段时期内,研制和装备坦克的国家却在试图缩小坦克炮的口径和长度。这与各国对坦克作用的认识有关,当时人
Long history of the first battle into the battle tank used in the tank during the World War I type Ⅰ tank, the tank is divided into two types, one is installed “machine” gun “female” tank, and the other is to install artillery “Male ” tank. “Male ” tank artillery was originally the British Navy’s naval gun, caliber 57mm, body length 40 times caliber. Since then until the early World War II, the caliber and length of the gun has maintained a world record. It is not self-evident that increasing the caliber of artillery and increasing the length of barrel will inevitably raise the power of artillery. However, for some time since the advent of the tank, countries that were developing and equipping tanks were trying to reduce the caliber and length of tank guns. This is related to the understanding of the role of nations in the role of the tank
