Yoh tanks are distinctive in terms of their unusual looks and then some. Each project featured unique shapes and mechanics, but those designs never got to the production line. What's special about these tanks?
Here's the original mapped out tank proposal.
Tank Plan: Gun Shield and Turret
The new gun shield incorporated many desirable factors. The primary feature consisted of the weight being concentrated aft of the trunnion, helping to balance the gun. The shield is composed of a light weight cored casting, to which the gun cradle is attached, permitting the gun to recoil. The sloped front provided excellent obliquity. The turret opening was completely sealed by the unique contour which maintained a minimum gap between the shield and turret.
Tank Plan: Ammunition Grab
The second suggestion was an ammunition hoist, to help the loader grab those heavy rounds.
An ammunition grab was developed in an effort to provide the simplest possible kind of assistance in lifting heavy shells. The grab was held in the loader's left hand, leaving his right hand free to guide and control the movement of the round. All controls for the hoist and grab were incorporated in the grab itself. Squeezing the latch grips locked the grab on the shell. Pressure is released by squeezing the trigger. The grab could also be used to replenish the ready racks. When not in use, the grab could be compactly stowed near the turret roof.
Tank Plan: Armored Ready Rack
This method of stowing the "Ready" ammunition offered maximum safety to the crew. It eliminated the fire hazard through which 90% of the tanks were lost in World War II. The device was made to prevent fragments from striking the ammunition. If a projectile entered the rack, the resulting ammunition fire would be vented out of the tank, saving crew and equipment. In addition to the protection feature, the commander could select the proper round by remote control. The loader would receive the round in a position that allows ease of handling.
The diagram may be understating things a little — the hatch may not be strong enough to divert an ammunition explosion up through the bottleneck chimney. Still, interesting example of thought.
Tank Plan: Automatic Loading Mechanism
This proposal indicated a method of loading the gun automatically. Eighteen rounds of 105-mm ammunition were stowed in the mechanism located in the "Bustle" of the turret. The commander pressed a button indicating the desired type of ammunition. A tray then received the round from the storage compartment and conveyed it to the center of the gun. A pushing arm rammed the round into the breech and waited above the breech for the gun to be fired. After recoil and shell ejection, the pusher reversed and discarded the empty casing out of the tank, and came to rest in a position to receive the next round.
