General Information
The Inf Tank Mk I was designed in 1935, manufactured by Vickers-Armstrong and was in use from 1936 to 1940.

The vehicle was powered by Ford 'V8' petrol powerplant producing 70 HP which could drive the vehicle on roads at up to 8 mph with a range of about 90 miles before refuelling. Its cross country performance was poor providing a max speed of about 4 mph and a range of about 36 miles.

It was armed with 1 light machine gun , a Vickers Medium Machine Gun. The Matilda was originally designed as an Infantry support tank - so slow moving with thick armour and a single man turret with a machine gun.

History
The Vickers medium machine gun was designed during World War I as a replacement for the Maxim gun from which its design was taken.

It served throughout World War I and II as a fixed point machine gun used to suppress areas and act as a defensive point.

Hit Probability(%) 98

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
