The Tank, Infantry, Valiant (A38) was a British tank design of the Second World War that only reached the prototype stage. It was intended to meet a specification for a well-armoured, light-medium tank, for use against Japanese forces in the South-East Asia theatre. 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. [3]

Design and development

The Valiant, under General Staff specification A38, began as a candidate for an assault tank, with the thickest armour on the lowest possible weight, for use in the Far East. It was to be similar in intention to the 40-ton A33 Excelsior although far lighter. As the Valiant managed the same 114 mm frontal armour with only 27 tons, it managed to achieve its primary goal, but only by making unacceptable compromises elsewhere. [1] At a time when British tank design was already at its nadir, this "terrible price for the weight concession" [1] led to what is probably the worst British tank of the war. [1]

The design brief of December 1943 called for three prototypes of a small, heavily armoured tank for the Far East. Speed across open country was less important, as was performance against armour. Design work started with Vickers, but they soon passed it to Birmingham Railway Carriage & Wagon, it was passed to Rolls Royce Clan Foundry where it was given more armour around the transmission increasing the weight then finally Ruston & Hornsby, who completed the single prototype in 1944. [3] Vickers' original intention may have been to use parts of their Valentine infantry tank where possible, [4] but this did not survive the production choices of the other manufacturers, nor was the running gear of the far lighter Valentine compatible with the needs of such heavy armour. The largest point of commonality was the choice of engine, the 210 bhp (160 kW) General Motors 6004 two-stroke diesel, as used in later marks of Valentine.

Construction was like that of the Matilda infantry tank – large cast armour pieces bolted together. Suspension was by six equally sized wheels on each side, with independent wishbone suspension units for each, rather than bogies. Concern was expressed about the possible fragility of these units in combat, but Valiant was never taken seriously off-road to test them. The drivetrain was to the rear, from a 210 bhp (160 kW) diesel. This low power limited the tank to a predicted top speed of 12 mph (19 km/h), although this was still acceptable for an infantry tank or assault tank.

Following from the later Valentine VIII and XI models, the turret was to accept either the QF 6 pounder or the QF 75 mm, with space for a turret crew of three (commander, gunner, loader). This was achieved at the cost of a large heavy turret with near-vertical faces and a massive cast front face with distinctively prominent bolts. The mantlet was internal and a weak point against accurate fire at close range. Unlike the late model Valentines it had a co-axial machine-gun.

The Valiant's suspension was tested by the Fighting Vehicle Proving Establishment (FVPE) at Chertsey in May 1945. The first day gave minor problems and was abandoned after only 13 miles (21 km) of easy on-road driving. However, the driver was already exhausted by this time, finding that the steering levers needed his full weight to operate and that the seat, footbrake and gear lever all carried risk of physical injury in using them. The Officer in Charge decided to abandon the trials there and then as it was impossible and unsafe to continue, reporting that "in his view the entire project should be closed". [3] There were also issues with weight distribution and the ground clearance of only 9 inches (23 cm), and by that point of the war there was no longer a need for the tank. [5] The Valiant project was terminated.

Variants

A Valiant II was mentioned in late 1943, [3] but little more was heard of it. In February 1944 there was more detailed discussion of a "Heavy Valiant", [3] which may have been the same and has been reported as such in some sources. [4] [ failed verification ]

The Heavy Valiant was a substantially different vehicle, only using the turret and driver's compartment of the Valiant on a hull derived from the A33 Excelsior and its T1 suspension. This gave armour of 9 inches (230 mm) on the hull front and 10 inches (250 mm) on the turret. Weight was now estimated at 42 tons, which is comparable with the original Excelsior despite almost doubling the armour thickness, and so this must have been a much smaller tank. Power was doubled to cope with the weight, using the new and compact 400 bhp (300 kW) Rolls-Royce Meteorite engine (a cut-down V8 Meteor) and an improved transmission. [3] The mistake of the Valentine was to be repeated, where the turret was up-gunned to the 95 mm howitzer of the Centaur IV at the cost of forcing the commander to take over the loader's task in a two-man turret. There is a record of a prototype having gone to the ranges at Lulworth Cove for trials in January 1945, but no other record of what it looked like. [3]

Present day

The sole Valiant was retained by the School of Tank Technology, where students were treated to an inspection of it at the end of their course and invited to find fault. David Fletcher wrote of this: "One hopes they started early in the morning." [3]

The Valiant can now be seen at The Tank Museum.

The Cromwell tank, officially Tank, Cruiser, Mk VIII, Cromwell (A27M), was one of the series of cruiser tanks fielded by Britain in the Second World War. Named after the English Civil War–era military leader Oliver Cromwell, the Cromwell was the first tank put into service by the British to combine high speed from a powerful, reliable engine and reasonable armour. The intended dual-purpose high-velocity gun could not be fitted in the turret, so a medium-velocity dual-purpose gun was fitted instead. Further development of the Cromwell combined with a high-velocity gun led to the Comet tank.

Crusader, in full "Tank, Cruiser Mk VI, Crusader", also known by its General Staff number A.15, was one of the primary British cruiser tanks during the early part of the Second World War. Over 5,000 tanks were manufactured and they made important contributions to the British victories during the North African campaign. The Crusader only saw active service in Africa but the chassis of the tank was modified to create anti-aircraft, fire support, observation, communication, bulldozer and recovery vehicle variants.

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.

The Tank, Cruiser, Challenger (A30) was a British tank of World War II. It mounted the QF 17-pounder anti-tank gun on a chassis derived from the Cromwell tank to add anti-tank firepower to the cruiser tank units. The design compromises made in fitting the large gun onto the Cromwell chassis resulted in a tank with a powerful weapon and reduced armour. However, the extemporised 17-pounder Sherman Firefly conversion of the US-supplied Sherman proved easier to produce and, with delays in production, only 200 Challengers were built. The Challenger was able to keep up with the fast Cromwell tank and was used with them.

The Ordnance Quick-Firing 17-pounder was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to "up-gun" some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle. As a tank gun, it was succeeded by the 84 mm 20 pounder.

<span class="mw-page-title-main">Infantry tank</span> Class of 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.

The Vickers Main Battle Tank Mk. 4 later known as the Vickers Valiant was a main battle tank developed as a private venture by British company Vickers for export. Its development began in 1976 and ended in January 1984. Although the Valiant did not enter production, its development provided valuable experience in the production of an aluminium-hulled, Chobham-armoured tank in the 40 tonnes weight range. A further development of its turret was later used for the Vickers Mk. 7 MBT.
