Design

Like Mk III but with cast turret. 84: 6 pdr. Early versions had Mk 5 6 pdr with counterweight on end.

Variants

  • Churchill MK IV:
  • Churchill Mk IV (NA75): With the experience gained in North Africa, and the fact that the 6 pdr. had no high explosive ammunition, it was decided to install the 75 mm gun and mantlets from wrecked Shermans. 21st Tank Brigade, 1st Army in North Africa fitted 120 Mk IVs with these 75 mm guns.

Usage

First saw action in Tunisia.

Used in Sicily and Italy to 1945.
