Heavy Tank, TOG

The TOG I Heavy Tank was a design for a massive tank that was developed by a group of tank experts from the First World War. Despite several years of effort and tests on the sole prototype very little came of their efforts.

In the summer of 1939 Leslie Burgin, the newly appointed Minister of Supply, met with Sir Albert Stern, the secretary of the Land Ship Committee and a key figure in the development of the tank during the First World War, to discuss what sort of tanks might be needed in the increasingly likely war with Germany. On 5 September Sir Albert was asked to form a committee to carry out the same task. Stern managed to gather a distinguished group of colleagues. Amongst them were Walter Wilson (engineer, gear-box expert and joint inventor of the tank), Sir William Tritton (Joint inventor of the tank and chairman of Fosters of Lincoln, the company that built the first British tanks), Sir Harry Ricardo (an important engine designer during both World Wars), Ernest Swinton (Army Officer and joint inventor of the tank) and Eustace Tennyson D'eyecourt (Director of Naval Construction for the Royal Navy 1912-1924). In October 1939 the committee was officially named the Special Vehicle Development Committee of the Ministry of Supply, but for obvious reasons it became known as 'The Old Gang', and their two designs as the TOG I and TOG II.

The Old Gang was given a general specification to work with. The new tank was one of a series that was designed to cope with the possibility of something resembling trench warfare, along with the Shelled Area Infantry Tank A20. It would be slow, with a speed of only 5mph, and short ranged (only 50 miles). It was to have all-round track, be able to cross heavily shelled areas and be armoured against 47mm and 37mm anti-tank guns and 105mm howitzers at 100 yards. It was to be armed with a field gun in the hull front and carry 2-pounder guns in sponsons and Besa machine guns. Ideally it would be diesel powered.

The first design was drawn up by Tritton's company Fosters in December 1939. Power would be provided by a Paxman-Ricardo 450hp V12 diesel, up-rated to 600hp. An electric transmission system was chosen, where the diesel engine powered two electric motors, one for each track. When power was reduced to one of the tracks, the tank would turn in that direction. The TOG was a very old fashioned looking tank, very clearly resembling a First World War rhomboid tank.

The design was soon changed to carry a 2-pounder gun in a Matilda II (A12) turret. A French 75mm howitzer was chosen for the hull gun, and the mounting from the French Char B tank was used. This made the TOG I a very heavily armed vehicle for its time.

Work on the prototype of the TOG I began in February 1940 and its first trials took place on 27 September 1940. The first official demonstration of the massive vehicle came on 6 October. By this point Churchill had come to power, and his relationship with Stern was fairly poor. The war situation had also changed - the German blitzkrieg had ended any chance of a muddy stalemate between the Maginot and Siegfried Lines, and the slow heavy TOG I was no longer needed. Despite that work continued on it for several years, although the development of the Churchill Infantry Tank (A22) meant that the British Army actually had a slow moving, heavily armoured infantry tank.

In early tests the electric transmission proved to be a failure. The motors were put under too much strain, and burnt out during the tests. These lasted until June 1941, and then stopped while a new hydraulic transmission was developed. With the new system the tank became the TOG IA. This system, which wasn't ready until May 1943, was also a failure, as there was too much time lag within the hydraulics. A basic problem was that the TOG was three times longer than wide, making it very difficult to steer.

The TOG IA was moved to Chobham early in 1944, and then disappeared, presumably scrapped as obsolete.

COBI TOG 2 - Super Heavy Tank: Set #2544

The TOG 2 - British prototype super-heavy tank began being developed in the early stages of World War II. The design erroneously assumed that the war would take the form of trench warfare, as was the case in the previous world conflict. TOG 2, like its predecessor, was slow. With an enormous weight of over 81 tons, it could only reach speeds of 13-15 km/h, but its massive size made it possible to transport several infantry soldiers. It was also armed with a 17-pound gun. Only one was ever produced and is today a valuable exhibit at the Bovington Tank Museum. The TOG 2 is an extremely popular tank among military enthusiasts and players of the World of Tanks computer game. Funny nicknames such as "Sausage", "Hot Tog" or "Dachshund" stuck to it, which are an expression of admiration and slight mockery of the dimensions of this huge machine.

The TOG 2 set was developed in collaboration with COBI and the Bovington Tank Museum. The model consists of 1225 high-quality COBI construction blocks and is 41 cm long. The characteristic camouflage has been reproduced using colored blocks and permanent prints that do not wear off even during intensive use. The tank is equipped with a rotating turret, a movable barrel and a detailed engine located under a hinged service hatch. Working tank traction allows you to move the vehicle, for example on a desk or the floor.

The TOG 2 set will surely bring a lot of satisfaction to both younger fans of blocks and adult enthusiasts of history and armored weapons. The tank will also certainly look spectacular both on the desk of collectors and fans of computer games.

• 1,225 high-quality blocks
• Produced in the EU by a company with over 20 years of tradition
• Meets the safety standards for products for children
• Fully compatible with other brands of construction blocks
• Only permanent prints without the use of stickers were used
• Blocks with prints do not scratch or smear and do not fade during play or under the influence of temperature
• Clear and intuitive instructions based on illustrations and step-step directions
• The model was created in cooperation with the Bovington Tank Museum
• An additional brick with the printed model name

British TOG II Heavy Tank History:

The Tank, Heavy, TOG II* was a prototype British tank design produced in the early part of the Second World War in case the battlefields of northern France devolved into a morass of mud, trenches and craters as had happened during the First World War. When this did not happen the tank was deemed unnecessary and the project terminated. A development of the TOG I design, only a single prototype was built before the project was dropped.

The second design to come out of the Special Vehicle Development Committee (nicknamed “The Old Gang” as it was made up of people who had worked on the original British tanks of the First World War) the TOG 2 was similar to the TOG 1 and kept many of its features. Instead of the track path arrangement of the TOG 1 which – like that of the First World War British tanks – ran up over the top of the hull and back down, the track path was lower on the return run and the doors were above the tracks. Ordered in 1940, built by Foster’s of Lincoln, the prototype ran for the first time in March 1941.

Under the Sea

Valentine Tank fitted with the Duplex Drive floatation system – a large screen to displace enough water to make it float. The vehicles using this system were vulnerable to overtopping by waves and the canvas could easily be perforated by enemy fire. The tank could not fire back with the screen deployed. Source: Divernet and BBC respectively

The biggest difference between this SVDC vehicle and preceding designs was going to be that this vehicle was not going to try and float, but drive on the sea floor instead. The logic for this decision was as simple as it may be initially counter intuitive. Whilst on the surface, on pontoons or with a screen (like a Straussler system), a tank would be visible to the enemy the entire time and unable to fire back. At the mercy of enemy gunnery, casualties could be inflicted even before they reached the beach, at which point the encumbrance of the floatation equipment would be a big problem. Indeed, in 1940 this had not yet been overcome with Straussler equipment, explosive removal of wading equipment and waterproofing compounds to seal the vehicle.

The 1940 solution for the SVDC was both unusual and innovative in that, whilst on the seafloor, the tank would be completely immune to enemy fire and be able to rise out of the water at the surf instantly ready to fire on the surprised enemy watching these poseidon-esque vehicles rising from the depths.

On the sea bed, the tracks would be able to engage with the sand and shale at a higher speed than on the surface without worrying about a rip tide or breakers. In fact, the SVDC estimated a sea floor speed of 6 knots and, at the same time, completely removed the complications of a propeller or the as-yet-to-be-designed steerable water jets from Messrs. William Foster and Co. As the vehicle was in contact with a tractable surface (sand and shale of the beach) there were no worries about the vehicle becoming trapped in the surf onshore, as could easily happen with a floating tank with little purchase on the beach at this key point. A large vulnerable floating target therefore stranded on the foreshore like a whale could be avoided by just being underwater could the equal risk of becoming damaged on the way to shore with a pontoon becoming holes and the tank capsizing or sinking.

The obvious question over an underwater vehicle is the problem of keeping water out, however this is not as big of a problem as may be imagined. With a submersion duration of just 3 minutes, a small bilge pump capable of pumping 30 gallons (136 litres) per minute against a head of 25 ft. (7.6 m) of water was more than adequate for the task. The next obvious problem is air for the crew and engine. For the engine, this was provided for with tanks of compressed air and for the crew by simply battening down the hatches to prevent air escaping. There was plenty of breathable air inside the volume of the hull and turret for the time submerged. It is not that there was no time for escape either. Designed for submarines, the Davis Escape Apparatus was already available in 1939 and, by 1944, the Tank Underwater Escape Breathing Apparatus would also be widely available. That piece of kit provided up to 7 minutes of oxygen for each crew man to get to the surface of the water in case of a problem requiring escape.

Navigation underway was to be aided by means of a spot lamp on the turret and a compass, although it was accepted that submerged rocks might be a problem for which there was no easy solution, although most of the large ones had already been well charted.

History [ edit | edit source ]

The second design to come out of the Special Vehicle Development Committee, or as it was called "The Old Gang", the TOG 2 was similar to the TOG 1 and kept many of its features but mounted the turret of the Challenger A30 cruiser tank with the QF 17-pounder (76.2 mm) gun. Instead of the track path arrangement of the TOG 1 which was like that of the First World War British tanks, the track path was lower on the return run and the doors were above the tracks. Ordered in 1940, built by Foster's of Lincoln, the prototype ran for the first time in March 1941.

Although equipped the same electro-mechanical drive as the TOG 1, the TOG 2 used twin generators and no problems were reported. It was modified to include among other things a change from the unsprung tracks for a torsion bar suspension and as the TOG 2* trialled successfully in May 1943. No further development occurred, although a shorter version, the TOG 2 (R) was mooted. The TOG 2 can be seen at the Bovington Tank Museum.

One of the major concerns of the Western Allies fighting Germany in World War II was that they would finally have to invade Germany from the west along a frontier protected by the ‘Westwall’, or ‘Siegfried Line’. This took the form of a line of concrete emplacements armed with artillery and anti-tank guns, and itself &hellip

Another example of the penchant of the Nazi hierarchy for the desirability of the massive, the Panzerkampfwagen E-100 (Gerät 383) was a super-heavy tank design which was conceived and developed in the second half of World War II.

1. K-Wagen, Germany

In 1917 the Imperial German Army began producing the A7V the first tank in German history. The A7V had its flaws, but the potential was evident. The Germans continued pursuing improved tank designs hoping to turn the tide of the war.

Around the same time, the K-Wagen was given the green light for production. The pioneer of German tank design, Joseph Vollmer, was instructed to produce a tank intended to be used in break-through situations.

Only one out of two prototypes of the K-Wagen was completed, shortly after the war ended. However, it was destroyed following the Versaille Treaty, which forbade the German army to produce and possess tanks in its military arsenal.

The tank was a true monster of its time it was armed with four 77 mm guns together with seven machine guns. It contained a crew of 27 people and weighed 120 tons. Despite its heavy armament, the armor was only 30 mm thick. Compared to WWII tanks, this armor would put the K-Wagen into light tank category.

Historical Picture

The 4.25 inch recoilless gun is unique to the TOG-2 and 3. The roughly 108mm caliber projectile does great work against armour and can damage through cover.


The TOG II is a premium tier VI British heavy tank.

With patch 9.22, the T95 received a speed buff, making this tank the slowest tank out of all tanks in the game, having a speed limit of only 15 km/h and slow reverse of 7 km/h with a measly hp/t ratio of 7.93.

It's armor is quite thin also. It's is only 76mm but it can still do some effective sidescraping. The turret armor is 114mm thick, so it can do some hull down against weak guns like the M5 Stuart. However, it has a MASSIVE hit point pool of 1400, which can be used to afford soaking up shot.

The armament is like any other. However, it is quite nice, with 150mm of penetration, decent RoF and DPM, nice gun depression of -10, but powerful gold ammo, with a penetration value of 239mm! Be wary though, APCR normalizes less than AP, so be considerable of your shots with the APCR, shooting flat(er) sections of armor.

Because of the massive length of this tank, it can cross some gaps that other normal tanks cannot (As it was designed based on trench warfare). It can also block passages and corridors that other tanks cannot do like the TOG II. It also weighs 81 tons, so it is pretty resistant to ramming to nearly all tanks. Even if you do manage to damage via ramming, it will be so minuscule, that the TOG II user can just shrug off the damage.

Based on the original TOG I, it was designed by the "Old Gang" the ones who designed and built the Mark I tanks in the First World War (Note that war was based on trench warfare). Instead of the tracks returning over the top, it returned lower and was covered. The doors were installed to access the tracks. Initially, the design included the 6-pounder (57mm) gun and was fitted with the dummy gun and turret for first runs. It also planned to have side-sponsons, but they never came into the tank physically. In 1942, it was then given the turret of the Challenger and the 17-pounder (77mm) gun. Trials started in 1943, and resulted in success. However, no further development occurred, although a revised version, the TOG II (R), was proposed. It was 6ft shorter, no sponsons, and used torsion bar suspension instead.

Although the project never reached mass-production, it did introduce new innovations, including diesel-electric generators that powered the tank.

The surviving prototype of the TOG II can be seen at the Bovington Tank Museum.

Customer Reviews

This is a huge kit and certainly doesn't disappoint. I was very impressed with the intricacy of the camouflage pattern that is replicated and achieved by using both bricks and printed plates (the latter only on the side and used to save pieces), the effect is a very close resemblance to the real thing. Indeed it's nice to see the steadily evolving quality of COBI builds (the gun in particular is much sturdier than some of my older models) and this tank certainly makes a good centrepiece (the little brick with the sign on is a nice touch). My only misgiving is that a pair of the one-stud-sized sloped pieces are very similar to one another, and disrupted the track action when mixed up, however this was quickly fixed once I examined the 'horns' of the vehicle and swapped the offending pieces around. Just pay attention to the instructions and be sure to build this on a table with plenty of space!

I pre ordered this for my son as he's tank mad , we've found in the past odd bits missing from cobi models but this time everything there. Took several days for my 9yr old to build but worth in the end . With the addition that we're supporting the tank museum an added bonus .

Pre-ordered this and built it over 4 nights last week. took my time and it took about 6 hours for me while watching a bit of TV at the same time. (would have been quicker if you open the bags into pots to search for the parts, I had to work with the bags) Instructions were good and clear. You just need to check you are using the exactly right shaped parts, as there are a few that are very similar. these are pointed out in the manual. The bricks come in 4 big bags which each contain smaller bags of parts, I split up the build by doing one bag a night. Build was fun, and not too repetitive, what you would expect for a Tank.
Part quality is very good, just as good as Lego for the most part, a few mould marks but nothing that affects the final appearance.
Looks great on my shelf, I recommend this.

Purchased for my son who collectes Cobi Tanks, planes and now ships
Excellent cobi kit that was he really enjoyed to make it was Solid, Heavy, Big (as you would expect from a TOG) and he was blown away with the certificate that it arrived with
