Galerie de photos d’un Marque V Mockup, The Mark V was a British heavy tank project from the First World War. After having made plans for the continued development of the Mark I into the Mark IV, the Tank Supply Committee (the institute planning and controlling British tank production) in December 1916 ordered the design of two new types: the Mark V and the Mark VI. The Mark V should embody the most advanced features that could still be incorporated into the Mark I hull. The Mark VI should abandon the old hull entirely, reflecting only some general principles of the older tank.

The Evolution of the Great War’s « Landship »

Lla Marque V was the final and most successful iteration of the heavy rhomboid tanks that defined the Western Front. While it looked nearly identical to its predecessors (the Mark I and IV), it was a revolutionary leap forward internally. Developed in 1917, it solved the most grueling problem of early tank warfare: steering. For the first time, a single driver could control the entire 29-ton beast, allowing the tank to finally function as a coordinated weapon of war rather than a clumsy mechanical monster that required four men just to make a turn.

Design Engineering: The Epicyclic Revolution

  • Wilson’s Epicyclic Steering: In the older Mark IV, the driver had to signal two « gearsmen » at the rear to engage or disengage secondary gearboxes to turn. The Mark V used Major Walter Wilsons epicyclic gearbox, which allowed the driver to control the speed and steering of both tracks by himself via levers. This made the Mark V significantly more maneuverable in the chaos of No Mans Land.
  • The Ricardo Engine: Specifically designed for tank use by Harry Ricardo, this 150-hp engine was the first of its kind. It was designed to run even when tilted at extreme angles while crossing trenches and featured a highly efficient cooling system to prevent the crew from being baked alive (though internal temperatures still reached 50°C/122°F).
  • Rear Cab and Semaphore: The Mark V featured a small raised « cab » at the rear for the commander, which included a semaphore signaling system to communicate with other tanks or infantry, as radio was still in its infancy.
  • The Unditching Beam: A massive wooden beam was carried on rails on top of the tank. If the tank got stuck in deep mud, the crew would chain the beam to the tracks; as the tracks moved, the beam would be pulled under the tank, providing the traction needed to pull the vehicle out of the mire.

Combat History: From Amiens to the Russian Civil War

  • Battle of Amiens (1918): The Mark Vs debut was a triumph. During the « Hundred Days Offensive, » hundreds of Mark Vs smashed through the Hindenburg Line, proving that massed armor could break the stalemate of trench warfare once and for all.
  • « Hermaphrodite » Variantes: Learning from early tank-vs-tank combat, some Mark Vs were modified with one « Male » sponson (6-pounder gun) and one « Female » sponson (machine guns). This ensured the tank could handle both enemy bunkers and swarming infantry.
  • Service in Russia: After WWI, the British sent Mark Vs to support the « blanc » Russians against the Bolsheviks. Many were captured by the Red Army and remained in Soviet service well into the 1930s, even being used in the defense of Tallinn during WWII in 1941!
  • Longevity: Remarkably, a few Mark Vs were dug into the ground as static pillboxes during the defense of Berlin in 1945, nearly 30 years after they were built.
