Design

Had round driver's port and escape doors.

The commander had a new cupola which allowed for better viewing when buttoned up. There were eight episcopes in the revolving turret hatch.

Due to the heavier armor and features it weight about a ton more than previous Churchills. A heavier suspension and improved gearbox were installed. The speed was governed to 12 3/4 mph.

Was also the basis for the Churchill Crocodile.

Usage

Was main tank in three Churchill tank brigades in Normandy.
