The Tank, Cruiser, Challenger (A30) was a British tank of
World War II. It mounted the 17 Pounder gun on a chassis
derived from the Cromwell tank to add heavier anti-tank
firepower to the cruiser tank units.
The design compromises made in fitting the large gun onto
Cromwell chassis resulted in a tank with a powerful
weapon, but with
less armour. The extemporised Sherman
conversion of the US-supplied Sherman to take the
17 pounder was easier
to produce and, combined with delays
in production, meant that only 200
Challengers were built.
However, it was able to keep up with the fast
and was used alongside them.
The Tank, Cruiser, Comet I (A34) was a British cruiser tank that
first saw use near the end of World War II. It was designed to provide
greater anti-tank capability to Cromwell tank
squadrons. It was armed
with the 77mm HV which was effective against
late war German tanks
and a superior weapon to the 75mm gun of the Panther when firing
APDS rounds. As a development of the Cromwell, it was an interim
design before the Centurion tank.
The Comet saw post World War II combat during the Korean war, and
remained in British service until 1958. Comets sold to other countries
continued in some cases to operate into the 1980s.
