The Sherman Medium Tank The Sherman could be considered the main British tank from the end of 1942 until the end of the war, the Sherman was first used by the British in North Africa, several hundred of these vehicles arrived in North Africa and the Middle East in 1942 and played a major role in the battles fought at the end of the year. In total the British received around 17,500 Shermans during WWII, more than any single British tank that was produced during the war. Initially the Sherman was well protected against the majority of the German weapons it faced and it also was able to deal with virtually any German armour but as the war progressed the Sherman's armour offered little protection against the larger German weapons and it's gun began the struggle against the thicker German armour. Due to the number of lend lease Shermans being available British tank production was scaled down significantly in 1943 and 1944 (down for 7,300 and 4,000) but it also allowed the British to concentrate on more useful vehicles than just large numbers. It's probably unfair to compare the Sherman to Panthers and Tigers as the Sherman is a significantly lighter vehicle than these, a better comparison would be against the Panzer IV which made up the bulk of the German tank force, against this it is well matched. The Sherman's biggest advantages where that it was easy to mass produce and it fired an excellent high explosive shell. By the Summer of 1943 the British wanted as many tanks as possible to be mounting a 17pdr gun, the A.30 (Challenger) seemed like the only British vehicle that would be able to mount a 17pdr within a reasonable amount of time and so it was decided to attempt to mount the gun in the Sherman which had a bigger turret ring that British vehicles. Getting the 17pdr to fit into the Shermans turret was difficult due to the size of the gun but eventually they were able to by adding a welded box at the back of the turret. Firing trails were completed in December 1943 and the first vehicles were converted to carry 17pdrs in January, these would become known as the Sherman Firefly. By the start of June 342 vehicles had been converted, the conversion rate increased rapidly and peaked in September with 268 being converted in that month. At this stage the Americans had grossly underestimated the loss rate of Shermans (as well as other equipment) and had anticipated the war ending by December and had cut down production so at the end of the year arrivals to the UK were stopped in November/December. The War Office had set much higher rates of loss compared with the Americans and thus still had a full reserve available. But this caused concerns with the War Office as it meant less vehicles being available for conversion to 17pdr and if the war continued until mid 1945 and no more Shermans arrived there may be a shortage of Shermans, luckily British tank production was still running and plans to cut production in 1945 were cancelled. This is why you see an increase in British tank production at the start of 1945. The total number of Sherman Firefly tanks was 2,246 "B" vehicles are armed with a 105mm Howitzer and "C" vehicles a 17 Pounder Name | I | IB | IC | II | IIA | USA Name | M4 | M4 | M4 | M4A1 | M4A1 | | | | | | | Production Date | | | | | | Total Production | | | | | | | | | | | | Crew | 5 | 5 | 4 | 5 | 5 | (In turret) | 3 | 3 | 3 | 3 | 3 | | | | | | | Length | 19'-9" | 20'-1" | 24'-4" | 19'-9" | 24'-3.5" | Width | 8'-7" | 8'-7" | 8'-7" | 8'-7" | 8'-7.5" | Height | 8'-11.75" | 9'-5.5" | 8'-11.75" | 8'-11.75" | 9'-8.5" | | | | | | | Weight | 30.8 | 31 | 32.75 | 30.8 | 31.55 | Ground pressure | | | | | | Ground clearance | 17.125" | 17.125" | 17.125" | 17.125" | 17.125" | | | | | | | | | | | | | Engine | Wright Petrol | Wright Petrol | Wright Petrol | Wright Petrol | Wright Petrol | B.H.P per ton | 11.9 | | 11.9 | 11.1 | | Max road speed | 22.1 | | 22.1 | 23.9 | | Average road speed | 19.25 | | 19.25 | 20 | | Cross Country Speed | 12.85 | | 12.85 | 12.5 | | Gear box type | Synchromesh | Synchromesh | Synchromesh | Synchromesh | Synchromesh | Gears | 5 Forward 1 Reverse | 5 Forward 1 Reverse | 5 Forward 1 Reverse | 5 Forward 1 Reverse | 5 Forward 1 Reverse | | | | | | | | | | | | | Fuel consumption (road) – MPG | 1.175 | | 1.175 | 1 | | Fuel consumption (cross country) | 0.498 | | 0.498 | 0.52 | | Petrol | 180 | 154 | 180 | 154 | 154 | Auxiliary capacity | | | | | | Radius of action (road) | 180 | | 154 | 154 | | Radius of action (cross country) | 75 | | 75 | 80 | | Trench Crossing | | | | | | Vertical obstacle | | | | | | Fording height | | | | | | Gradient | | | | | | | | | | | | Main Armament | 75mm M3 | 105mm How M4 | 17 Pounder Mk IV | 75mm M3 | 76mm M1A1 | Ammunition | | | | | | Secondary Armament | .3" Browning | .3" Browning | .3" Browning | .3" Browning | .3" Browning | Ammunition | | | | | | Transverse type | Hand & Electric | Hand & Electric | Hand & Electric | Hand & Electric | Hand & Electric | Max elevation | 25 | 35 | 20 | 25 | 25 | Max depression | 10 | 10 | 5 | 10 | 10 | Turret Ring Size | 69" | 69" | 69" | 69" | 69" | Optics | | | Pict No.43 x 3 L Mk I | | | | | | | | | Armour | | | | | | | | | | | | Hull Nose | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | Hull Front | 50.8 | 63.5 | 50.8 | 50.8(Cast) | 50.8(Cast) | Hull Sides Upper | 38.1 | 38.1 | 38.1 | 38.1 | 38.1 | Hull Sides Lower | 38.1 | 38.1 | 38.1 | 38.1 | 38.1 | Hull Rear Lower | 38.1 | 38.1 | 38.1 | 38.1 | 38.1 | Hull Rear Upper | 38.1 | 38.1 | 38.1 | 38.1 | 38.1 | Hull Roof (Front) | 19.05 | 19.05 | 19.05 | | | Engine Deck | 12.7 | 12.7 | 12.7 | 12.7 | 12.7 | Hull Floor | 12.7 | 12.7 | 12.7 | 12.7 | 12.7 | Hull Floor (Front) | 25.4 | 25.4 | 25.4 | 25.4 | 25.4 | | | | | | | Turret Mantlet | 76.2(Cast) | 76.2(Cast) | 76.2(Cast) | 76.2(Cast) | 76.2(Cast) | Turret Front | 76.2(Cast) | 76.2(Cast) | 76.2(Cast) | 76.2(Cast) | | Turret Roof | 25.4(Cast) | 25.4(Cast) | 25.4(Cast) | 25.4(Cast) | 25.4(Cast) | Turret Sides | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 63.5(Cast) | Turret Rear | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 50.8(Cast) | 63.5(Cast) | | | | | | | Rear Box Rear | | | 63.4 | | | Rear Sides | | | 50.4 | | | Rear Box Roof/Floor | | | 25.4 | | | Name | III | IV | IVB | V | VC | USA Name | M4A2 | M4A3 | M4A3 | M4A4 | M4A4 | | | | | | | Production Date | | | | | | Total Production | | | | | | | | | | | | Crew | 5 | 5 | 5 | 5 | 4 | (In turret) | 3 | 3 | 3 | 3 | 3 | | | | | | | Length | 20'-1" | 20'-1" | 20'-6.5" | 21'-4" | 25'-6" | Width | 8'-7" | 8'-7" | 8'-7" | 8'-7" | 8'-7" | Height | 8'-11.93" | 8'-11.93" | 9'-5.5" | 8-11.75"' | 8-11.75"' | | | | | | | Weight | 31.25 | 31.5 | 31.25 | 31.75 | 34.75 | Ground pressure | | | | | | Ground clearance | 17.125" | 17.125" | 17.125" | 17.94" | 17.94" | | | | | | | Engine | G.M Duel Diesel | Ford G.A.A.
