The Assault Tank T14 was a joint project between the United States and the United Kingdom with the goal being to produce a universal infantry tank.

Contents

The T14 project never came to fruition, as a pilot model was not delivered to the UK until 1944 by which time the British Churchill tank had been in service for two years and greatly improved over its initial model. US efforts working on a similarly well-armoured tank but with a higher speed for use other than in infantry support led to the T20 Medium Tank.

Design and development

In 1941, the head of the United States Ordnance Department travelled to Britain to learn of their experience, ideas and requirements for the future. Among the discussion was the possibility of designing a well-armed and armoured combat vehicle, one that was stronger than the British Churchill infantry tank then in production.

The tank design would have a British QF 6-pounder (57 mm) or a US 75 mm gun and share many parts with the M4 Sherman; they had the same armour thickness, but with sloped armour at extreme angles, effective armour on the T14 was greatly increased to 101 mm (4.0 in). [3]

The British initially ordered 8,500 in 1942 following which detail design work started. Testing of the pilot model which was completed in 1944 showed the vehicle to be much too heavy for practical use. By this time, the British Army was satisfied with the Churchill and its cruiser tank designs and further production of the T14 was halted.

Only two were built; one tested in the US and the other sent to Britain. [4] The example sent to Britain survives in The Tank Museum, Bovington. [4] The British had developed the Heavy Assault Tank A33 "Excelsior" design to the same specification as the T14 but this did not go into service either. [5]

An armoured fighting vehicle or armored fighting vehicle (AFV) is an armed combat vehicle protected by armour, generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked. Examples of AFVs are tanks, armoured cars, assault guns, self-propelled artilleries, infantry fighting vehicles (IFV), and armoured personnel carriers (APC).

<span class="mw-page-title-main">Tank destroyer</span> Type of armoured fighting vehicle designed to engage and destroy enemy tanks

A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.

The Infantry Tank Mark II, best known as the Matilda, is a British infantry tank of the Second World War.

<span class="mw-page-title-main">Churchill tank</span> British heavy infantry tank

The Tank, Infantry, Mk IV (A22) Churchill was a British infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple bogies, its ability to climb steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allied tanks of the war.

<span class="mw-page-title-main">Cruiser Mk I</span> British cruiser tank

The Tank, Cruiser, Mk I (A9) was a British cruiser tank of the interwar period. It was the first cruiser tank: a fast tank designed to bypass the main enemy lines and engage the enemy's lines of communication, as well as enemy tanks. The Cruiser Mk II was a more heavily armoured adaptation of the Mark I, developed at much the same time.

<span class="mw-page-title-main">Cruiser Mk II</span> British cruiser tank

The Tank, Cruiser, Mk II (A10), was a cruiser tank developed alongside the A9 cruiser tank, and was intended to be a heavier, infantry tank version of that type. In practice, it was not deemed suitable for the infantry tank role and was classified as a "heavy cruiser". It served briefly in World War II.

<span class="mw-page-title-main">Comet (tank)</span> British cruiser tank

The Comet tank or Tank, Cruiser, Comet I (A34) was a British cruiser tank that first saw use near the end of the Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank and mounted the new 17 pdr High Velocity (HV) gun, in a lower profile, partly-cast turret. This gun was effective against late-war German tanks, including the Panther at medium range, and the Tiger.

<span class="mw-page-title-main">Cruiser tank</span> Tank

The cruiser tank was a British tank concept of the interwar period for tanks designed as modernised armoured and mechanised cavalry, as distinguished from infantry tanks. Cruiser tanks were developed after medium tank designs of the 1930s failed to satisfy the Royal Armoured Corps. The cruiser tank concept was conceived by Giffard Le Quesne Martel, who preferred many small light tanks to swarm an opponent, instead of a few expensive and unsatisfactory medium tanks. "Light" cruiser tanks carried less armour and were correspondingly faster, whilst "heavy" cruiser tanks had more armour and were slightly slower.

<span class="mw-page-title-main">Infantry tank</span> Tank

The infantry tank was a tank concept developed by the United Kingdom and France in the years leading up to World War II. Infantry tanks were designed to support infantrymen in an attack. To achieve this, the vehicles were generally heavily armoured to allow them to operate in close concert with infantry even under heavy fire. The extra armour came at the expense of speed, which was not an issue when supporting relatively slow-moving foot soldiers.

<span class="mw-page-title-main">Heavy tank</span> Heavily armed and armored tank

Heavy tank is a term used to define a class of tanks produced from World War I through the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes.

<span class="mw-page-title-main">Tortoise heavy assault tank</span> British assault gun design/prototype

The Tortoise heavy assault tank (A39) was a British heavy assault gun design developed during the Second World War, but never put into mass production. It was developed for the task of clearing heavily fortified areas such as the Siegfried Line and as a result favoured armour protection over mobility.

<span class="mw-page-title-main">Tank classification</span> Categorizing tanks by weight or role

Tank classification is a taxonomy of identifying either the intended role or weight class of tanks. The classification by role was used primarily during the developmental stage of the national armoured forces, and referred to the doctrinal and force structure utility of the tanks based on design emphasis. The weight classification is used in the same way truck classification is used, and is intended to accommodate logistic requirements of the tanks.

<span class="mw-page-title-main">Ram tank</span> Canadian medium tank

The Tank, Cruiser, Ram was a cruiser tank designed and built by Canada in the Second World War, based on the U.S. M3 Medium tank chassis. Due to standardization on the American Sherman tank for frontline units, it was used exclusively for training purposes and was never used in combat as a gun tank. The chassis was used for several other combat roles however, such as a flamethrower tank, observation post and armoured personnel carrier.

<span class="mw-page-title-main">Excelsior tank</span> British experimental infantry tank

The Tank, Heavy Assault, A33 (Excelsior) was a British experimental heavy tank based on the Cromwell (A27) design developed in the Second World War. It was developed when there were concerns as to performance of the Churchill tank.

A Kangaroo was a Canadian armoured personnel carrier (APC) during the Second World War which was created by converting a tank chassis.

The prototype demonstrated that the design was a failure and this sole example produced was retained by the School of Tank Technology as a lesson to its students.
