The Comet is a British tier 7 medium tank.

A further development of the Cromwell cruiser tank, this British tank saw service in World War II. A total of 1186 vehicles were manufactured from September 1944 through late 1945.

The Comet is a tank well suited for flanking, as its armor is neither good nor bad for its class it wont survive brawls for long periods of time. It sports a couple of advantages over the Cromwell, such as a gun mantlet and lowered profile on the upgraded turret. However, it gets an "almost" inadequate top gun, barely an upgrade over the 75mm HV. What is more, in the footsteps of its predecessor, its handling and speed are somewhat slower, being barely better than those of the Panther and not quite as good as those of the T20. Clever use of flanking tactics and gun depression are necessary to successfully play this tank.

The Comet leads to the Centurion Mk. I.

Historical Info

Comet Prototype

Combat experience against the Germans in the Western Desert Campaign demonstrated to the British many shortcomings with their cruiser tanks. Hence a request was made in 1941 to the Nuffield Organisation and Leyland Motors Ltd for a new heavy cruiser tank that could achieve battle superiority over German models. For reasons of economy and efficiency, it had to use as many components as possible from the current A15 Cruiser tank Mk VI Crusader tank.

The initial designs submitted were the A24 Cruiser Tank Mk VII Cavalier tank from Nuffield powered by a Nuffield-Liberty L-12 engine and the A27L Cruiser tank Mk VII Centaur tank from Leyland, which was also powered by the Liberty L-12 but would be able to use the more powerful Rolls-Royce Meteor when it became available.

The Cruiser tank Mk VII A27M Cromwell was the third parallel development to the Cavalier and Centaur. The Cromwell's Meteor engine proved to be very reliable and gave the Cromwell good mobility, but some problems did appear. The tank was prone to throwing its tracks if track tension was not maintained properly or if it turned at too high a speed or too sharply. There were also some problems with suspension breakage, partly due to the Cromwell's high speed.

A 17 pounder version of the Cromwell, the A30 Cruiser Mk VIII Challenger tank, was under development. To handle the large gun, the Cromwell hull had to be lengthened and a large turret set on top. Due to the slow production of Challengers, the Sherman Firefly (a Sherman tank fitted with the 17 pounder gun) conversion received official support. Until the Challenger was available, one Firefly would be issued to each Cromwell troop (giving three Cromwells and one Sherman Firefly); but this was unsatisfactory due to the different maintenance requirements and associated supply complication of two tank models, as well as the performance difference between Cromwell and Sherman.


A34

Comet tank advancing towards Lubeck, May 1945

With the A34 (the General Staff specification), later named Comet, the tank designers opted to correct some of the Cromwell's flaws (the track shedding and broken suspension problems) and enhance the Cromwell's main strengths, low height and high speed. Originally, it had been expected that the tank would use a new gun from Vickers: the "High Velocity 75mm". However, as designed, the gun would not fit into the turret size available. So the gun was changed to a different gun, the "77mm HV". This gun used the same calibre (76.2 mm) projectile as the 17-pounder but the shell casing was from the older QF 3 inch 20 cwt gun loaded to higher pressures. The resulting round was completely different to 17-pounder ammunition. It had a lower muzzle velocity than the 17-pounder but the ammunition was much more compact and more easily stored and handled within the tank. This made it possible to mount the gun on a smaller turret ring - the Challenger turret had been so large to allow space for two loaders - without making the hull wider. Several other improvements were made: armour protection was increased, the hull and turret were welded[2] with a cast gun mantlet, ammunition was stored in armoured bins, the suspension was strengthened, return rollers were added and the turret was electrically traversed (a design feature taken from the Churchill tank), with a generator powered by the main engine rather than the hydraulic system of the Cromwell.

Armour on the Comet ranged from 32 mm to 74 mm on the hull, while the turret was from 57 to 102 mm. The Comet tank's top speed was limited from the Cromwell's 40+ mph to a slower, but respectable 32 mph (51 km/h) to preserve suspension and engine components and to reduce track wear. The mild steel prototype was ready in February 1944 and entered trials. Although concerns about the hull gunner and belly armour were put to one side (to avoid redesign), there was still sufficient delay caused by minor modifications and changes that production models did not begin to be delivered until September 1944. Intended to be in service by December 1944, crew training was delayed by the German Ardennes Offensive. By the end of the war, 1,200 had been produced. Comet was fitted with two radio sets: a No. 19 Wireless, for communication with the regiment and the troop, and a No. 38 Wireless for communication with infantry units. Like many British tanks, it also had a telephone handset mounted on the rear so that accompanying infantry could talk to the crew.
