During World War II, Britain has designed three variants of the 305-mm (12-inch) railway howitzers. In the first model (Mark 1) stood at 12 long gun calibers, but the army has demanded more long-range artillery systems, and as a result there was 17 Internal cylindrical model Mark 2, firing range which increased from 10 200 to 13 700 meters.

However, this gun could only fire along the railroad tracks with an angle pointing up to 20 ° on both sides – otherwise recoil it would carry off the rails. The army command was granted an increase in the firing range, but wanted to have a weapon that can lead a circular firing. As a result, the firm was created howitzer Vickers Mark 5, which had a fire in 240 degrees. When preparing to fire guns on the ground on both sides of the road fell special props.
