由于 M1坦克使用120毫米滑膛炮后,重量将会超过55吨,因而美国对研制减少装甲容积的顶置式炮架的坦克发生兴趣。图为这种顶置式炮架坦克的模型图。在顶置式炮架后面是主炮的供弹装置,弹药储存在动力装置和战斗室之间的空间内。三名乘员均在底盘的前部,驾驶员和车长的座位与车体无相对运动,炮手的位置在顶置式炮架下面。该车负重轮的布置和动力室的结构形状,有可能使该方案以 M1底盘为基础。达种无炮塔坦克与 M1比较,预计,外形降低,重量将显著减轻。但是,在弹药存放
As the M1 tanks use more than 55 tons of 120-mm smoothbore gun, the United States has become interested in developing tanks with overhead gunheads with reduced armor volume. The picture shows a model of this overhead gun turret model. Behind the overhead gunhead is the projectile bomb, which is stored in the space between the powerplant and the battle room. The three occupants were on the front of the chassis with no relative movement between the driver and the captain’s seat and the bodywork. The gunner’s position was below the overhead mount. The layout of the truck wheels and the configuration of the powerhouse make it possible to base the program on the M1 chassis. Breathless tank with M1 compared to the expected shape reduced, the weight will be significantly reduced. However, ammunition is stored
