Development started in the spring of 1942. After undergoing trials, the decision was made to replace the 57 mm gun with a 75 mm gun. The vehicle passed trials in the fall of 1942, but never saw service.

Specifications

Before World War II, the British military was concerned with building a fleet of new tanks. It was to be headed by a new super-heavy tank for storming enemy positions. The British had experience in building such vehicles since World War I.  They were clumsy huge moving fortresses with powerful armor and armament. Therefore, the object called "TOG II" also had these qualities. 

The armored monster with a weight of 82 tons, a height of 3 m, and a length of more than 10 m had to strike fear into the enemy. Like its predecessors, the running gear of the tank was concealed inside the hull, and the tracks protruded from the central part, which was an armored capsule for weapons and a crew of six. 

At first, the designers had an idea to hang the armament also on the sponsons, but then it was moved to the front of the tank and the sponsons became part of the main body. Hatches were made in them for the ejection of shells and loading of ammunition. 

The main gun of the 'TOG II' was a 75mm 'QF 17 pounder' anti-tank gun, the best in its class in service in Great Britain. In addition to this, the front of the tank had a slot for a 7.92mm "BESA" machine gun.

"The TOG II' was propelled by a 600 hp 'Paxman-Ricardo' engine. The speed of the tank was not high, but its purpose was not to make a rapid assault but to destroy trenches and fortifications of the enemy and destroy tanks and manpower of the enemy. The role of the tank as a mobile gun was also considered, but later this idea was rejected.
