M55自行榴弹炮 - 照片和视频

M55自行榴弹炮的照片， M55 was an American fully enclosed and armored self-propelled artillery based on the M53 155 mm assault gun. It had a 203.2 mm howitzer which could traverse 30° left or right, carrying only 10 rounds of ammunition. The gun had a maximum range of 16,916 meters with a rate of fire of one round every two minutes. The M55 armor was light, 25 mm maximum, but sufficient to protect the crew from indirect artillery hits or small arms fire. The M55 used components of the M47 Patton tank, but the automotive aspects were reversed. The engine was mounted in the front and drove through a front-drive sprocket. The driver’s cupola is visible on the front left of the turret, and spare track blocks were stored on the turret front. Because the driver’s seat was in the turret, a special seat was used to keep the driver facing forward, independent of the turret facing. The M55 was used during the Vietnam War, and subsequently withdrawn from service in the US military.

M55自行榴弹炮是美国在1950年代开发的一种功能强大且用途广泛的火炮系统。基于M53 155毫米自行火炮，M55拥有更大的203.2毫米（八英寸）榴弹炮，可以发射各种射弹，包括高爆弹，核弹，化学弹和烟雾弹。M55可以向左或向右移动30°，常规弹药的最大射程为16.92公里（10.51英里），火箭辅助射弹的最大射程为30公里（18.64英里）。M55有六名乘员，在其炮塔中携带了10发弹药。
M55旨在为装甲和步兵部队提供重型火力支援，以及对敌方火炮的反电池火力。M55还能够发射核弹，这使其在威慑或摧毁敌军方面具有战略作用。M55使用了M47巴顿坦克的部件，但将发动机和变速箱反转到车辆前部。这为 M55 提供了更好的重量分布和机动性，并保护发动机免受后方攻击。M55的最高时速为48公里/小时（30英里/小时），续航里程为260公里（160英里）。
M55于1952年在美国陆军服役，并在冷战期间部署在北约地区。M55在越南战争中参加了战斗，在那里它被用来轰炸敌人的阵地并为地面部队提供火力支援。M55还出口到多个国家，包括比利时，土耳其，西班牙，西德和台湾。M55最终被美国陆军的M110榴弹炮取代，后者的枪管更长，射速更快。M55 在 1960 年代退役，但有些直到 1990 年代仍在其他国家服役。
