The Landkreuzer P 1500 Monster was a German pre-prototype super-heavy self-propelled gun designed during World War II, representing the apex of the German extreme artillery designs.[citation needed]

The Renault FT (frequently referred to in post-World War I literature as the FT-17, FT17, or similar) was a French light tank that was among the most revolutionary and influential tank designs in history. The FT was the first production tank to have its armament within a fully rotating turret.^{[note 1]} The Renault FT's configuration – crew compartment at the front, engine compartment at the back, and main armament in a revolving turret – became and remains the standard tank layout. As such, some historians of armoured warfare have called the Renault FT the world's first modern tank.^[2]

Over 3,000 Renault FT tanks were manufactured by French industry, most of them during 1918. Another 950 of an almost identical licensed copy of the FT (the M1917 light tank) were made in the United States, but not in time to enter combat.

The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. Thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British for the American Civil War general William Tecumseh Sherman.

Leonardo Da Vinci's tank concept (15th century)

"Karl-Gerät" (040/041) (German literally "Karl-device"), also known as Mörser Karl, was a World War II German self-propelled siege mortar (Mörser) designed and built by Rheinmetall. Its heaviest munition was a 60 cm (24 in) diameter, 2,170 kg (4,780 lb) shell, and the range for its lightest shell of 1,250 kg (2,760 lb) was just over 10 km (6.2 mi). Each gun had to be accompanied by a crane, a heavy transport trailer, and several modified tanks to carry shells.

Seven guns were built, six of which saw combat between 1941 and 1945. It was used in attacking the Soviet fortresses of Brest-Litovsk and Sevastopol, bombarded Polish resistance fighters in Warsaw, participated in the Battle of the Bulge, and was used to try to destroy the Ludendorff Bridge during the Battle of Remagen. One Karl-Gerät has survived and the remainder were scrapped after the war.

The Tsar Tank (Russian: Царь-танк), also known as the Netopyr' (Нетопырь) which stands for Pipistrellus (a genus of bat) or Lebedenko Tank (танк Лебеденко), was an unusual Russian armoured vehicle developed by Nikolai Lebedenko (Николай Лебеденко), Nikolai Zhukovsky (Николай Жуковский), Boris Stechkin (Борис Стечкин), and Alexander Mikulin (Александр Микулин) from 1914 onwards. The project was scrapped after initial tests deemed the vehicle to be vulnerable to artillery fire.

It differed from modern tanks in that it did not use caterpillar tracks—rather, it used a tricycle design. The two front spoked wheels were nearly 9 meters (27 feet) in diameter; the rear-mounted third wheel was only 1.5 metres (5 feet) high. The upper cannon turret reached a height of nearly 8 meters. The hull was 12 metres wide with two more cannon in sponsons. Additional weapons were also planned under the belly. Each wheel was powered by a 250 hp (190 kW) Sunbeam engine.^[1]

The huge wheels were intended to cross significant obstacles. However, due to miscalculations of the weight, the rear wheel was prone to getting stuck in soft ground and ditches, and the front wheels were sometimes insufficient to pull it out. This led to a fiasco of tests before the high commission in August 1915. The tank remained in the location where it was tested, some 60 kilometres from Moscow until 1923 when it was finally taken apart for scrap.

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.^{[3][better source needed]} By the end of the war, a single prototype chassis of the E-100 had been produced, and it was only partially completed. After the war, the prototype was shipped to the United Kingdom for trials, but was later scrapped.

The basic design was ordered by the Waffenamt as a parallel development to the Porsche Maus in June 1943. It was the heaviest of the Entwicklung (E) series of vehicles, meant to standardize as many components as possible. The proposed designs were the E-5, E-10, E-25, E-50, E-75 and finally the E-100.^[4]

In March 1944, the Adler company in Frankfurt submitted blueprint 021A38300 for a super-heavy tank called E-100, after the tank was proposed in April 1943 along with the other Entwicklung series vehicles.^{[5][better source needed]} According to the blueprints, the tank would be armed with a both a 149 mm gun and a 75 mm gun. Two types of engines were proposed: one was a 700 hp Maybach HL230, with a transmission and turning mechanism borrowed from the Tiger II. The estimated top speed was 23 km/h. The second variant would have a new 1200 hp Maybach engine and a top speed estimated at 40 km/h. The design had removable side skirts and narrow transport tracks to make rail transport more viable. This design was very similar to the original 'Tiger-Maus' proposal, but had larger 900 mm diameter road wheels and a new spring based suspension rather than the original torsion bars. A new turret was designed; intended to be simpler and lighter than the Maus turret. Permission was given to produce the tank based on the potential use of the E-100 as a tank destroyer with either a 15 cm StuK L/63 or 17 cm StuK L/53 gun.^{[5][better source needed]}

In July 1944 Hitler ordered the development of super heavy tanks to stop. Work on the E-100 continued at a very low priority, with only three Adler employees available to assemble the prototype.^[6]

The first prototype was never fully completed and was found by the 751st Field Artillery Battalion of the American forces in April 1945. The partially completed vehicle was taken by the British Army for evaluation and then scrapped in the 1950s.

The Panther is a German medium tank deployed during World War II on the Eastern and Western Fronts in Europe from mid-1943 to the war's end in 1945. It had the ordnance inventory designation of Sd.Kfz. 171. It was designated as the Panzerkampfwagen V Panther until 27 February 1944, when Hitler ordered that the Roman numeral "V" be deleted. Contemporary English language reports sometimes refer to it as the Mark V.

The Panther was intended to counter the Soviet T-34 and to replace the Panzer III and Panzer IV. Nevertheless, it served alongside the Panzer IV and the heavier Tiger I until the end of the war. It is considered one of the best tanks of World War II for its excellent firepower and protection, although its reliability was less impressive.^[5]

The Panther was a compromise. While having essentially the same engine as the Tiger I, it had more efficient frontal hull armour,^[6] better gun penetration, was lighter and faster, and could traverse rough terrain better than the Tiger I. The trade-off was weaker side armour, which made it vulnerable to flanking fire. The Panther proved to be effective in open country and long range engagements, but did not provide enough high explosive firepower against infantry.^[7]

Though officially classified as a medium tank, its weight is more like that of a heavy tank, as its weight of 44.8 tons puts it roughly in the same category as the American M26 Pershing (41.7 tons), British Churchill (40.7 tons) and the Soviet IS-2 (46 tons) heavy tanks. The tank had a very high power to weight ratio however, making it extremely mobile regardless of its tonnage. Its weight still caused logistical problems however, such as an inability to cross certain bridges.
