The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value.

AnnoGB41_Challenger.png

1380000

The Challenger is a British tier 7 turreted tank destroyer.

Created in 1942 based on the extended chassis of the Cromwell. One definite advantage of the new vehicle was its 17-pounder gun, which was the most powerful British gun at that time. This allowed the tank destroyer to effectively hit the enemy at distances up to 1,000 meters. However, the vehicle had a large silhouette and the chassis was overloaded. A total of about 200 vehicles were built.

It is often called one of the worst tier 7 tank Destroyers, although in actuality, once you are past the first gun and turret, it becomes a reasonable competitive vehicle as long as you play on a map with ample concealment. Under the right circumstances it can be used as either a sniper, or a flanker, though it is not ideal in either role.


The Challenger leads to the Charioteer.

Player Opinion

Pros and Cons

Pros:


  • Very fast speed and surprisingly good traverse (for a TD), can let it play a flanking role or fall back when in danger
  • Great gun depression of 10 degrees all around the tank
  • Good gun handling and accuracy lets even less experienced players nail shots frequently
  • Very fast RoF compensates for the horrible alpha damage
  • Has a turret and pivots unlike most TDs of same tier


Cons:


  • Not particularly good penetration on gun, 171mm of pen. It is ok at its tier, but will struggle with higher tier targets
  • Large size and thin armor makes you easy pickings for enemy tanks, especially arty
  • 2nd turret has a mere 40mm of frontal armor (200mm on the back, which is rarely useful)
  • Very low alpha damage for its tier


Performance

This tank suffers from a poor synergy between the vehicle and the gun. The 17 pounder's low alpha damage requires that you hit targets repeatedly in order to do significant damage, but the vehicle lacks the armour to stand up to return fire and it's large silhouette and poor camouflage values make this tank difficult to conceal (even with camo-oriented setup, most enemies will spot you from about 350m). The resulting combination is reminiscent of an M18 Hellcat that lacks the 90 mm gun. This is playable at Tier 6, but for a Tier 7 vehicle it poses considerable difficulties.

In theory, the role of this tank is long-range sniping. Its decent mobility allows it to take advantageous positions early and quickly change positions, should such need arise. However, the low alpha damage means that you will rarely be able to finish off your target before it disappears from view. Unfortunately, there is no practical alternative. Avoid close-range fighting - poor armor, slow traverse and low accuracy while moving make you an easy prey for most light and medium tanks you encounter. After the Buff in update 9.15, it is a reasonably effective flanking tank, especially with the top gun and turret and on maps such as Malinovka, where the good maneuverability and fast-firing gun will allow you to harass enemy tanks from behind rather effectively. An important aspect to this way of playing the Challenger is planning. The turret traverse is very slow, so you need to turn it in the right direction well in advance, the follow whatever route past the target that you have chosen. Keep in mind that the Challenger lacks a gun mantlet, so working a ridge-line, or going hull down is not a viable option. When low tier, the Challenger can perform well as a passive scout. Just make sure not to fire any shots as it will cost you most of your camouflage

An interesting thing to note is that the stock turret of the Challenger is very similar to the turret on the TOG II*. This is not coincidental; during development, the TOG II* was fitted with a variety of turrets, the final configuration seen today in the Bovington Tank Museum and in the game used the Challenger's turret.


Early Research

The first thing that you definitely want to research is the gun, the tank is useless without the second gun and so it is a must.

Next, research the second turret, as it will give you a huge RoF boost and is actually lighter than the first.

After this, research everything else in any order, it doesn't really matter.

Note that if you've fully researched the Achilles, you'll have all modules available immediately with the exception of the turret and tracks. The 2nd turret is lighter than the stock turret, so the tracks can be researched last, if at all.


Suggested Equipment


Tank Gun Rammer Binocular Telescope Camouflage Net Improved Ventilation Class 2


Documented Tank and Crew Builds

Since stealth and manoeuvrability are your only defence, you will need to train camouflage on all crew members. Once the first skill is at 100 percent, immediately change the commander to sixth-sense. Skills like situational awareness and recon to increase the view range are also useful. However, keep in mind that this is not a tank you are likely to keep in your garage once you have unlocked the Charioteer, so additional crew-training should focus on the needs of future vehicles.

Historical Info

The Tank, Cruiser, Challenger (A30) was a British tank of World War II. It mounted the QF 17-pounder anti-tank 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 the Cromwell chassis resulted in a tank with a powerful weapon, but with less armour. The extemporised Sherman Firefly conversion of the US-supplied Sherman 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 Cromwell tank and was used alongside them.

The driving force in the development of Challenger was Roy Robotham. Robotham had been a Rolls-Royce executive in the car division who, with no work to do, had led a team to develop a tank powerplant from the Rolls-Royce Merlin aircraft engine. The Rolls-Royce Meteor gave the British a powerful, reliable engine, which would power the A27M Cruiser Mk VIII Cromwell tank. Robotham's contributions gained him a place in the Ministry of Supply and on the Tank Board, despite his lack of experience in tank design.[5]

The General Staff brought forward specification A29 for a 45-ton 17-pounder-armed cruiser tank based on needs identified in the African desert campaign. The design weight of this vehicle was too heavy however, and prior to manufacture the specification was passed over in favour of the alternate specification, A30 at 10 tons lighter.[6]

In 1942, an order for an A30 based tank was placed with Birmingham Railway Carriage and Wagon Company (BRC&W) expecting it to be based on the Cromwell components also being manufactured by BRC&W. Turret and gun mounting was in the hands of Stothert & Pitt. Birmingham Carriage had to modify the Cromwell hull to take a bigger turret.

The design received additional emphasis when it was found in May 1943 that the Cromwell was not going to be able to fit its intended armament. Vickers had been developing a 50-calibre-long 75mm "High Velocity" tank gun. It was realised late in the design process that the Cromwell's turret ring was too small to mount this 75 mm (3.0 in) gun.[7] Thus the Challenger would be the only British cruiser tank to mount a weapon that could tackle heavier German armour until the arrival of the A34 Comet.

British tank production was a limited resource however, and insufficient numbers could be made. In the lead-up to D-Day, Sherman tanks were upgraded with the 17-pounder creating the interim Sherman Firefly. Conversions of Sherman tanks to Fireflys was simpler than production of Challenger, and the A30 order was cancelled after about 200 had been built allowing BRC&W to focus on production of the Cromwell.

The tank was rendered obsolete when the Vickers HV 75 mm gun was developed to become the 77mm HV (actually 76.2 mm calibre) to arm the Comet tank. The 77mm HV used the same projectiles as the 17-pounder although with a reduced propellent charge compared to the 17-pdr. The 17-pdr was briefly used on earlier marks of Cromwell's successor -the Centurion tank.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

The Challenger in this game is an amalgamation of the Challenger cruiser tank and the Avenger tank destroyer. The Avenger utilised a new hull based on the Comet cruiser tank; the turret was never fitted to a Challenger.
