The A7V was a tank introduced by Germany in 1918, near the end of World War I. The name is probably derived from the Allgemeines Kriegsdepartement 7 Abteilung Verkehrswesen ("General War Department 7, Branch Transportation"), although some theorize that Hauptmann Joseph Vollmer gave the V to the name. In German the tank was called Sturmpanzer-Kraftwagen (roughly "assault armoured motor vehicle"). There were 100 ordered for the spring of 1918, but only 20 were delivered. They saw action from March to October that year, and were the only tanks produced by Germany in WWI.

The A7V was over seven metres long and three metres wide. The height varied up to three metres.

The crew normally consisted of up to sixteen soldiers and two officers: commander, driver, mechanic, mechanic/signaller, twelve infantrymen (six machine gunners, six loaders), and two artillerymen (main gunner and loader).

The A7V was armed with six 7.9 mm MG08/15 machine guns and a 5.7 cm gun mounted at the front. The 'female' variant had two more machine guns in place of the main gun. It is not entirely clear how many started this way or were converted. Some sources say only chassis 501 saw combat as a female.

The tank had 20 mm of steel plate at the sides and 30 mm at the front; however the steel was not hardened armor plate, which reduced its effectiveness. It was thick enough to stop machine gun and rifle fire, but not larger calibres. This offered protection comparable to the thinner armor of other tanks of the period, which used hardened steel.

Power came from two Daimler 4-cylinder engines delivering 100 hp (74 kW) each. The top speed was about 15 km/h on roads and 5 km/h across country. The A7V carried 500 litres of fuel (132 imperial gallons).

It was as slow as other tanks of the day, but had very poor off-road capability and was prone to getting stuck. The large overhang at the front and low ground clearance meant trenches or very muddy areas were impassable. However, on open terrain it could be used to some success and offered more firepower than the armoured cars that were available. Power to weight ratio was 6.8 hp/ton (5.1 kW/ton), trench crossing: 7 ft (2.3 m), ground clearance: 7.5 to 15.75 in (200 to 400 mm).

There were about 30 other chassis, mostly built without armour and used as field transporters.

[edit] Combat History

The A7V was first used in combat on March 21, 1918. It was deployed north of the St.Quentin Canal. The A7Vs helped stop a minor British breakthrough in the area, but otherwise saw little combat that day.

The first tank vs. tank fight in history took place on the April 24, 1918 when three A7Vs (including chassis number 561, known as "Nixe") taking part in an attack with infantry incidentally met three Mark IVs (two Female machine gun tanks and one Male with 6 pounder guns) near Villers-Bretonneux. During the battle tanks on both sides were damaged. According to the lead tank commander, 2nd Lt Frank Mitchell, the machine gun armed Female Mk IVs fell back after being damaged by armor piercing bullets. They were unable to damage the A7Vs with their own machine guns. Mitchell then attacked the lead German tank with the 6 pounders of his own tank and knocked it out. He hit it three times, and killed five of the crew when they bailed out. He then went on to rout some infantry with case shot. The two remaining A7Vs in turn withdrew. As Lt. Mitchell's tank withdrew from action, 7 Whippet tanks also engaged the infantry. Four of these were knocked out in the battle, and it is unclear if any of them engaged the retreating German tanks. Lt. Mitchell's tank lost a track towards the end from a mortar shell and was abandoned. The damaged A7V was later recovered by German forces.

All 18 available A7Vs had been put into action that day with limited results; two toppled over into holes, some encountered engine or armament troubles. After a counterattack, three ended up in Allied hands. One was unusable and scrapped, one used for shell testing by the French, and the third taken by the Australians.

The A7V was not considered a success and other designs were planned by Germany, however the end of the war meant none of the other tanks in development, or planned ones, would be finished (such as the Oberschlesien, K-Wagen, and LK series). The A7Vs were last used in October 1918; a number were scrapped before the war ended in November.

The extremely limited production of twenty made their contribution very limited, and most tanks (less than a hundred) that were fielded by Germany in WWI were captured French or British tanks (Beutepanzer). The French had produced over 3,600 of their FT-17, the most produced tank of WWI, and the British over 2,500 of their Mark I to V.

The captured A7V Mephisto is in the Queensland Museum in Brisbane, Australia.

A replica of the A7V "Wotan" is in the Deutsches Panzermuseum in Munster.
