Mouse Heavy Tank: Germans Fantasy Part II

Mouse Heavy Tank: Germans Fantasy Part II

System and Quality
The Gigantic object!
From the prospective of design, though Mouse had little difference with traditional tank, its design was totally different with past German tanks: it was brand-new from the shape to innner structure. It had two outstanding features: one was its huge size, the other was the electric transmission, and the two had some connection. The total length of Mouse (indlude the turret) was 12.66m (modern tanks are only 7m long), the length of the body was 10.085m, the width was 3.7, the height was 3.63, the bottom was 0.57m above the ground. The reason why it was so huge was that it equipped the electric transmission, the dynamo and coupling elements were 3m long which occupied 1/3 of the whole body! 
From the prospective of structure, the cab was in the center of frontal part and the driver plus the technician were in it. There was a tank in both flanks. The engine was behind the cab. The right side of the engine was cooling fan, the left radiator. And the powerful dynamo was in the back. The right side of the dynamo located the auxiliary power unit- diesel engine (8hp) and storage battery, the left is the ammunition room, the rear is gear-box. In the rear of the body, there were 2 dynamos that drived the main wheel and a auxiliary fuel tank whose capacity was 1000L.(All the informatiom above was the structure of V2. )

There are 3 benefits that Mouse used the electric transmission. One was continuously variable transmission which made it easy to handle. Another was that it was more stable compared to the mechanical gear box which were easy to fail. The last one was that the motor and the dynamo were separated and they used cable to transmit electricity hence it contributed to the comprehensive arrangement. But the electric transmission had one fatal disadvantage which was the capacity of the dynamo was too big and that was the biggest reason why tanks seldom use it.
The engine of Mouse V2 was Daimler-Benz MB 517 diesel engine. The capacity of the cylinder was 48.5L whose maximum power was 1080hp (784KW). The gear-box had two forward gears and one reverse gear. Since it used the electric transmission, the gear-box can be smaller or just abandoned. Its wheels were suspension alternate loading wheel which were commonly used in WWⅡtanks. The track was 1440mm wide, the track on the ground was 5880 long. But the unit pressure still reached 13.7MPa, far larger than common tanks. The bottom was 570mm above the ground, the maximum width of ditch was 4.5m, the maximum grade ability was 30 degrees, the maximum stroke was 186 kilometers.
The structure of Mouse V2 was special, as it should bear the 56 tons turret, it had many strengthened components which was rear.

Strong Power
The super heavy Mouse had strong power, its main turret was the most powerful in WWⅡ. Its turret was fitted with a 128 mm KwK 44 L/55 gun, with coaxial 75 mm KwK 44 L/36.5 gun and a 7.92 mm MG34 for anti-aircraft armament. To improve defense, the turret was equipped the integral casting protective gun shield. The initial speed of the tungsten alloy capped penetrators can reach 870m/s, it can penetrate 270 mm / 30 degree angle armor plate within 1000m, it can still penetrate the 156 mm / 30 degree angle armor plate within 3000m which means it can destroy the Sherman, Cromwell  and Churchill T-34/85 and IS-2 over 3500m with accuracy. Tanks of the Alliance did not have possibility to win in frontal encounter since they were destroyed without getting into the attack area. The turret had 68 bombs, 43 of them were on the rack, and the other 25 were on the rear. The bomb was 1.5m long and weighted 56kg. Due to the heavy weight of the bomb and they were separated, there were specialized mechanical auxiliary loading system, thus there should be two loaders to fire continuously.  But Mouse carried totally 200 bombs of 75mm long, among which 75 bombs were in the body, the rest were fixed vertically in the turret basket. In addition, there were 2 MG-34 machine guns which were equipped 4 caissons of 250 bullets. All weapons were fixed in the frontal part of the turret and they cannot pitch freely, the shooting area was minus 7 to plus 23 degrees. The turret weighted 56tons and was driven by electric motor. It can be rotated 360 degrees in 16 seconds.
Besides, there were periscope, sighting telescope, stereoscope range finder whose baseline was 2.2m and various handling equipment. Mouse was supposed to equip the Mauser MG-151 15mm anti-aircraft guns and 20mm submachine gun as the air defense weapons but never materialized. Since the frontal armor was too thick, it did not have too much space to radio operator, it did not equip the frontal submachine gun. What was funny was that, the military once ordered to add a large flamethrower, but Porsche thought it would be too heavy for it thus refused.  When Hitler saw the sample, he ordered that the main turret should be strengthened to a 150mm canon. Krupp actually made one, but it wasn't  developed until the Germany surrendered.  
       
All in all, from the prospective of power, Mouse was the best in WWⅡ.

Revive this beast in this age and I believe it will still be in the same level as the modern tanks - without even having modern sophistication.
