The Panzerkampfwagen VII Löwe (Lion) was a design for a super-heavy tank created by Krupp for the German government during World War II.
 The project, initially code-named VK 70.01 (K), never left the drawing board, and was dropped in 5–6 March 1942, in favor of Porsche's heavier Panzer VIII Maus.
The 7.5 cm KwK 42 L/70 (from "7.5 cm Kampfwagenkanone 42 L/70") was a 7.5 cm calibre German tank gun developed and built by Rheinmetall-Borsig AG in Unterlüß during the Second World War.
 The gun was used to equip the SdKfz.171 Panzerkampfwagen V Panther medium tank and the SdKfz.162/1 Jagdpanzer IV/70(A)/(V) tank destroyer.
 When mounted on a tank destroyer it was designated as the 7.5 cm Pak 42 ("7.5 cm Panzerabwehrkanone 42") anti-tank gun.
The Super-heavy tank Panzerkampfwagen IX and Panzerkampfwagen X were silhouette conceptual drawings in an edition of the German World War II "Signal" military magazine.
 The drawings were not based on any actual designs, and were solely printed to deceive Allied intelligence.
The Tank, Light, Mk VIII (A25), also known as the Harry Hopkins, after American President Roosevelt's chief diplomatic advisor, was a British light tank produced by Vickers-Armstrong during the Second World War.
 The Mk VIII was the last in the line of light tanks the company had built for the British Army, and was intended to be the successor of the previous light tank designed by Vickers-Armstrong, the Mk VII Tetrarch.
 A number of changes were made to the Mk VIII, most notably increasing its width, length and weight and also increasing the thickness of the armour.
 The design of the tank was submitted to the War Office in late 1941, with an initial order for 1,000 models being made by the Tank Board of the War Office in the same month, a number that increased to 2,410 in November.
 Production began in June 1942 but immediately began encountering problems with the tank, and a number of modifications had to be made to the design after complaints were made by the War Office and the Fighting Vehicle Proving Establishment.
 These problems were so acute that only 6 tanks had been produced by mid-1943, and only 100 when production ended in February 1945.
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944.
 It is the heaviest fully enclosed armoured fighting vehicle ever built.
 Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.
The "Panzerkampfwagen" E-100 (Gerät 383) (TG-01) was a German super-heavy tank design developed towards the end of World War II.
 It was proposed to be the basis for a heavy artillery system, an anti-aircraft vehicle, and a heavy tank destroyer - however - by the end of World War II the chassis of the E-100 was only partially completed.
 The tank was shipped to the United Kingdom at the end of the war for trials, but was later scrapped.
The Panzerkampfwagen 35(t), commonly shortened to Panzer 35(t) or abbreviated as Pz.Kpfw.
 35(t), was a Czechoslovak-designed light tank used mainly by Nazi Germany during World War II.
 The letter (t) stood for "tschechisch" (German: "Czech").
 In Czechoslovak service, it had the formal designation Lehký tank vzor 35 (Light Tank Model 35), but was commonly referred to as the LT vz.
 35 or LT-35.
The M22 Locust, officially Light Tank (Airborne), M22, was an American-designed airborne light tank which was produced during World War II.
 The Locust began development in 1941 after the British War Office requested that the American government design a purpose-built airborne light tank which could be transported by glider into battle to support British airborne forces.
 The War Office had originally selected the Light Tank Mark VII Tetrarch light tank for use by the airborne forces, but it had not been designed with that exact purpose in mind so the War Office believed that a purpose-built tank would be required to replace it.
 The United States Ordnance Department was asked to produce this replacement, which in turn selected Marmon-Herrington to design and build a prototype airborne tank in May 1941.
 The prototype was designated the Light Tank T9 (Airborne), and was designed so that it could be transported underneath a Douglas C-54 Skymaster transport aircraft, although its dimensions also allowed it to fit inside a General Aircraft Hamilcar glider.
The Panzer I was a light tank produced in Germany in the 1930s.
 The name is short for the German Panzerkampfwagen I ("armored fighting vehicle mark I"), abbreviated "PzKpfw I ".
 The tank's official German ordnance inventory designation was SdKfz 101 ("special purpose vehicle 101").
The VK 36.01 (H) was an experimental German heavy tank during World War II.
 The VK 36.01 H was further development of the VK 30.01 H experimental medium tank.
 There were only 8 chassies and one of the tanks built, the chassies and tank were built by Henschel.
 At the time Henschel was assigned with developing a break through weapon that would help defeat the Soviets.
 Also other experimental heavy tanks and super-heavy tank were built, designed, and tested in Henschel.
 The development of the V.K. 36.01 H lead to the development of the Tiger I tank, a tank that played an important role in World War II.
 The tanks development lead to other tank development also.
 Then in 1942 the project was stopped in favor of the VK 45.01.
