Design

Sir John Carden9 of Vickers Armstrongs designed the Cruiser Mk II to be an infantry support version of the A9 in 1934.4,13 It was decided it needed to be slower and have thicker armor.1

Turret

Twin "sub-turrets" were removed9,13 which allowed for more room for ammunition.1 It had the same turret and shaped hull, but it had additional armor bolted on the hull and turret.1,9,13 Gunner controlled the elevation of the gun with his shoulder.

Prototype

The first prototype appeared in 1936.8,12

By 1937 it was determined that the A10 did not have heavy enough armor and was cancelled.10 In 1938 it brought back and 75 were ordered.10

Production

Order for 100 was placed in 1938.1 First delivered in December 1939.8,12

    • Production: ? - September 194013

Variants

  • A.10E1: Prototype.10
  • Cruiser Mk II, A10: It was classified as a "heavy cruiser" but it suffered from poor performance in France.4
  • Cruiser Mk IIA: Had Besa coaxial machine gun.10
  • Cruiser Mk IIA CS: Close support.10 Had 3.7" (94 mm) howitzer installed in turret.10
  • Anti-Mine?: Could push Anti-Mine Reconnaissance Caster Roller.10 Had four rollers on a frame.10

Usage

The Cruiser Mk IIs were found to be too lightly armored and too slow.13
