The Churchill VII is another significant of the Churchill chassis, occasionally called the Heavy Churchill; this is due to being wider then the regular Churchill's as well as having a significant increase in armour.

The Churchill VII was the last significant variant of the Churchill, being the second most numerous variant in mass production. It was later redesignated to the A42 from 1945 onward.
