The E-100 was an experimental German WWII super heavy tank. The only prototype hull of this tank was built in 1943 or 1944. The car never entered mass production. The E-100 was to be powered by a single engine Maybach HL 230 P30 or Maybach HL 234 with 700 hp and 800 hp respectively. It was probably armed with a 128mm KwK 44 L / 55 gun and 2 machine guns MG34 cal. 7.92 mm.
Tank prototype The E-100 was created as part of the Entwicklungsserie program, a program for the development of German armor, which was to lead to a standardized design of a series of six tanks of different weights, but using as many common components as possible. The E-100 tank in this project was to be the heaviest tank, based on the chassis of the Pz.Kpfw VI Tiger II Ausf. B. The emphasis was on the strongest possible main armament and powerful armor - especially at the front of the turret and hull. However, the project, despite its far-reaching advancement, was abandoned in 1944, and the E-100 never entered mass production.
The Flak 40 is a German 128mm heavy anti-aircraft gun from the Second World War. The first prototypes of the guns were created in 1937, and in 1942 serial production began, ending with the production of about 600 guns of this type. The maximum vertical range was 14,800 m, and the initial velocity of the projectile was 880 m / s.
The Flak 40 was developed as part of the Rheinmetall project, which dates back to 1936, of a new heavy anti-aircraft gun. As the bombings on German cities were not perceived in the years 1937-1941, the work on Flak 40 was of a very low priority. This fact changed in 1942, which led to the implementation of a new gun into production. Originally, it was planned to create a mobile version of the Flak 40, but it was quickly switched to the production of only a stationary version, which was mounted on fortified sites or on the so-called "Flakturm Zoo". An attempt was also made to produce a double Flak 40 gun (the so-called 12.8 cm Flakzwilling 40/2), but production ended with the production of about 40-50 pieces of this weapon.
