开发过程 从1927年开始,经过近10年的建设,法德边界上的马奇诺防线坚固无比。为了攻破这道法国防线,德国陆军1935年决定开发可以发射巨大的混凝土破坏弹的臼炮。1936年3月设计工作正式开始。 最初德国按照一般臼炮进行设计,采用800毫米口径,使用4吨炮弹时,炮口初速为100米/秒,射程为1公里,使用2吨炮弹时,炮口初速加大到140米,秒,射程相应增至2公里。为了保证炮身仰角不变,德国决定采用炮口装填方式。 1936年10月,德国陆军武器局第4部提 Development process From 1927 onwards, after nearly 10 years of construction, France and Germany on the border line of solid fortification. In order to break this French defense line, the German Army decided in 1935 to develop mortar guns that could launch huge concrete bombs. 1936 March design work began. Germany first mortar according to the general design, the use of 800 mm caliber, the use of 4 tons of shells, the muzzle muzzle velocity of 100 m / s, a range of 1 km, with 2 tons of shells, muzzle muzzle velocity increased to 140 meters, seconds , A corresponding increase in range to 2 km. In order to ensure that the cannon elevation remains unchanged, Germany decided to adopt the muzzle loading method. October 1936, the German Army Arms Department 4 mention
