World War II
During early World War II, the Crusader was probably the best-known cruiser, it was first used in mid 1941 and thereafter used in large numbers in the Western Desert Campaign. The contemporary Covenanter was unreliable and was retained in the UK for training use.
The Cavalier, Centaur and Cromwell came out of the planned successor to the Covenanter and Crusader. Intended to be in production by 1942, the project was delayed and the Crusader was upgunned as an interim measure with the 6 pounder gun. Cavalier was a development of Crusader. Centaur and Cromwell were an alternative design using the same engine as the Cavalier and the new Rolls-Royce Meteor engine respectively.
The Centaur and Cromwell saw action from the Invasion of Normandy onwards. The Comet was a development of the Cromwell using a modified 17 pounder gun and was fielded in the beginning of 1945. By this point in the war, the firepower and armour protection of the cruisers made them indistinguishable from medium tanks.
In the course of the war, technological improvements enabled heavier tanks to approximate the speed of the cruisers and the concept became obsolete. The last of their line was the Centurion. The Centurion was designed to satisfy the "Heavy Cruiser" criterion by combining the mobility of a cruiser tank and armour of an Infantry tank in one chassis. This idea - and the Centurion along with it - then evolved into the "Universal tank" concept, a design that could "do it all". Ultimately, the Centurion tank transcended its cruiser tank origins and become Britain's first modern main battle tank.
The cruiser-tank concept was also employed by the Soviet Union in the 1930s, as exemplified by the BT tank series (Russian: bystrokhodniy tank, "fast tank").

Famous quotes containing the words war ii, world and/or war:
“I realized how for all of us who came of age in the late sixties and early seventies the war was a defining experience. You went or you didn’t, but the fact of it and the decisions it forced us to make marked us for the rest of our lives, just as the depression and World War II had marked my parents.”
—Linda Grant (b. 1949)
“The descendants of Holy Roman Empire monarchies became feeble-minded in the twentieth century, and after World War I had been done in by the democracies; some were kept on to entertain the tourists, like the one they have in England.”
—Ishmael Reed (b. 1938)
“In the present civil war it is quite possible that God’s purpose is something different from the purpose of either party.”
