Prototype King

This Tank's History
This Panzerkampfwagen VI Ausf B Tiger II tank (Sd.Kfz. 182) V2 Prototype is wrongly called the Porsche turret Tiger II. Both types of turrets used on the Tiger II tank were designed and built by the weapons manufacturing company called Krupp, but they are regularly designated as Porsche (the first, curved model) and Henschel (the latter model). It is worth noting that neither Porsche, nor Henschel built any turrets. The Panzer IV Ausf B Tiger II tank is also known as the Königstiger and Royal Tiger. This tank is also known as the V2 prototype.

The Porsche company submitted designs for a new tank chassis using the Krupp turret but it was very complicated to build compared to the Henschel hull. The Henschel company was awarded the contract for the successor of the Tiger I tank. Preparations were made for production, and three production prototypes (V1, V2, V3) were built in November 1943.

The first King Tiger Tank prototype V1 did not have the Zimmerit anti-magnetic mine coating, nor tooling or tool storage. The front mudguards were flat, with hinged sides extensions. Both the view port and pistol port in the turret sides were welded shut. The turret was of the early curved front Krupp model. The commander's cupola was protruding to the left side of the turret.

The two others prototypes were essentially the same as the V1 prototype, however, the V2 had a handwheel located on the firewall to close vents, in order to allow it to wade through deep water. All three prototypes were used at the factory for testing different modifications. The suspension on its left side was incomplete. Both the 80 cm (31.5 in) and 66 cm (26 in) wide tracks were tested on the prototypes. All three tanks were not intended to be used operationally just for testing. Mild steel was used to construct these text vehicles not armour plate.

The V2 prototype King Tiger was captured by British troops in the Heeres Waffenprufungamt (German Army Ordnance Testing Department) Haustenbeck, near Sennelager, Germany in 1945 and shipped to England. It was discovered with its tooling attached but without Zimmerit coating. It was painted in plain sand yellow Dunkelgelb livery.

Also captured at the same time was the V1 and V3 King Tiger prototypes, a Porsche chassis Jagdtiger, a Panther and the VK3001(H) tank prototype test vehicle. I believe the King Tiger tank V3 prototype had been painted with Zimmerit and had its gun destroyed after it was fired when the barrel was blocked.

To avoid the sonic resonance of metal on metal the wheel is fitted with internal rubber rings that separate the rim from the hub. It cuts down noise but it was also an ingenious solution to the shortage of rubber in Germany during the war. It was complicated to build and repair.

The V2 prototype King Tiger tank arrived in Britain in 1946 at the same time as the Jagdtiger tank destroyer and both went to the School of Tank Technology (STT) at Chertsey, Surrey, before being moved to Bovington.

When it first arrived at the museum from the School of Tank Technology it was missing its 88mm gun. A spare one, of a later design, was found and fitted. Its suspension on its left-hand side was still incomplete and it was missing its track guards.

V2 Prototype King Tiger II Ausf. B tank was armed with a 7.92mm MG 34 ball mounted hull machine gun. Another machine gun was fitted next to the main gun in the turret.

The Tiger II moved to the Tank Museum at Bovington in 1952. It now displays a unit tactical number 300 on its turret even though it was not issued to a German fighting battalion. It has been given the livery and turret number of a King Tiger that fought in the sPz. Abt 503.

It is missing the commander’s cupola and crew hatches. The wheels and tracks move so it can be towed into different positions within the museum. The Maybach 230 engine was removed and fitted to the Tiger I tank at the Tank Museum in Bovington after that vehicles Maybach 210 engine became damaged.

Only fifty of the Krupp built curved front turrets were made. They were fitted to production tanks. No more were made after it was found that the rounded front acted as a 'shell trap'. If an enemy shell hit the lower portion of the curved mantel it would be defected downwards onto the tank chassis roof above the driver and hull gunner's position. This area of the tank is comparatively thinly armoured. The other King Tiger turret made by Krupp alleviated this problem by having a flat thickly armoured front.


Known variously as the Tiger Ausf. B, Tiger II or Königstiger (the British also referred to it as the `Royal Tiger’)

This Tiger II was the second prototype of three built by Henschel, with the Chassis Number V2 (Versuchs-Fahrgestell No. V2 (Trial Chassis V2)), and completed in January 1944. It was not issued to a combat unit, remaining with Henschel were it was used for various trials. It was later captured by the British at the Henschel testing area in Haustenbeck, Germany at the end of the War. It is still fitted with a modified exhaust pipe that Henschel was using to test exhaust pressure.

The turret rear was designed to be removable to allow the removal and refitting of the 8.8 cm KwK 43 gun. On this particular tank the rear wall was removed and lost at some time Post-War and it has been replaced with a wooden panel. Also lost, presumably at the same time, was the commander’s cupola.

After its capture the vehicle had its original tracks replaced with a set of Kgs 73/800/152 single link cross-country tracks removed from a second Tiger Ausf. B (Chassis Number 280009 or 280012) that was also on site at Haustenbeck. These tracks had only been introduced in March 1945.
