The '''{{Specs|name}}''' was developed after early combat experience with Churchill infantry tanks. These tanks had very poor reliability and were also very slow for the modern battlefield. Thus, while the prototype A27 Cromwell was being developed, it was decided to use the A27 as a basis for a new universal tank meant to replace the cruiser and infantry tanks and combine them into a single vehicle. In 1942, the project was approved and the '''A33 Excelsior''' was born. However, the issues with the Churchill were fixed by 1943 and cruiser tanks were replaced by American M4 Shermans, thus the Excelsior was no longer needed and the project was cancelled.

The '''{{Specs|name}}''' (or just '''{{Specs|name}}''') is a gift rank {{Specs|rank}} British heavy tank {{Battle-rating}}. It was introduced in [[Update 1.67 "Assault"]] during the 2017 [[WW2 Chronicles|World War Two: Chronicle Event]], unlocked after obtaining 11 Chronicle Awards. Based off the [[Cromwell V|Cromwell]] chassis, the Excelsior provides a substantial armour upgrade with speed.
+
It was introduced in [[Update 1.67 "Assault"]] as a reward for the [[wt:en/news/4648-special-war-thunder-chronicles-en|2017 "War Thunder Chronicles"]] event. The Excelsior is a weird tank, since it combines reliable armour, with good mobility and decent firepower for its BR. The gun is a [[OQF Mk.V (75 mm)|75 mm OQF Mk.V]] with good penetration values, although it lacks access to APHE shells like most British tanks of WWII, the gun handling is also great at -12 degrees of depression. The tank is also fairly survivable, especially if it is angled, and also has access to smoke launchers to easily retreat or change position. However the reverse speed is very poor and it should be taken into consideration, while the armour is decent, the Excelsior is a very large target and will easily be spotted from far away.

The A33 Excelsior is a fast moving highly manoeuvrable, well armoured heavy tank offering great speed of up to 40 km/h. It excels at flanking and catching the enemy of guard. To get the best from this tank in battle, use it speed and manoeuvrability to your advantage. Since the Excelsior is a heavy tank it armour offers up to 114 mm of protection and if angled it can further increase it to offer over 210 mm. Allowing the tank to become immune to virtually all enemy rounds. However, the thickest parts of the armour plate is on the front of the tank and front of the turret, so it is important to keep the front pointed towards the enemy in combat.
 +
 
 +
Combined with the 75 mm cannon, which has a reload of up to five seconds, it is able to cause mayhem on the battlefield. load M61 Shot round and fire away, always aim for the sides and rear of the enemy tanks, this is the weakest parts, when at range. However, when fighting tiger tanks get as close as you can, approach from the rear and shoot the rear of the turret, it will knock the tigers turret out allowing you to head to its side and knock it out with some precision shots.
 +
 
 +
The A33 Excelsior, does not have any turret mounted machine guns, its roof armour is only 25 mm thick allowing enemy aircraft to cause havoc. To evade the aircraft use smoke and head towards any additional smoke rounds which you may fire, this will prevent the aircraft from following you and allowing you to evade them.

The early combat experience of the [[Churchill Mk III|Churchill infantry tank]] raised concerns on its reliability and speed, with a suggestion that production be halted while development focus on an "universal tank" for the British armoured forces to replace the cruiser and infantry tanks. However, until such a design could be formulated, they still needed a tank for the assault role the infantry tanks would take.

Rolls-Royce Company, the company producing the prototype [[Cromwell_V|A27 Cromwells]], suggested that the Tank Board use the A27 as an interim design with stronger armour, suspension, and armament. The suggestion was supported with the English Electric Company, whom plan to upgrade the A27 with thicker armour and elements from the American [[M6A1|M6 heavy tank]].

On 07 May 1942<ref name="TMuseumValiant">Newsome, Bruce. "TANK INFANTRY A38, VALIANT (E1952.39)." Tankmuseum.org. The Tank Museum, n.d. Web. 10 May 2017. [http://www.tankmuseum.org/museum-online/vehicles/object-e1952-39 Website]</ref>, Tank Board approved for the production of these uparmoured A27 under the designation '''A33''', though it would also have the name '''Excelsior'''. English Electric Company were in charge of producing the uparmoured A27 models and produced two prototypes. The first had the M6 suspension system and a [[Ordnance QF 6-pounder Mk.III (57 mm)|6-pdr]] cannon.

Description

The Tank, Heavy Assault, A33 (Excelsior) was developed after early combat experience with Churchill infantry tanks. These tanks had very poor reliability and were also very slow for the modern battlefield. Thus, while the prototype A27 Cromwell was being developed, it was decided to use the A27 as a basis for a new universal tank meant to replace the cruiser and infantry tanks and combine them into a single vehicle. In 1942, the project was approved and the A33 Excelsior was born. However, the issues with the Churchill were fixed by 1943 and cruiser tanks were replaced by American M4 Shermans, thus the Excelsior was no longer needed and the project was cancelled.

It was introduced in Update 1.67 "Assault" as a reward for the 2017 "War Thunder Chronicles" event. The Excelsior is a weird tank, since it combines reliable armour, with good mobility and decent firepower for its BR. The gun is a 75 mm OQF Mk.V with good penetration values, although it lacks access to APHE shells like most British tanks of WWII, the gun handling is also great at -12 degrees of depression. The tank is also fairly survivable, especially if it is angled, and also has access to smoke launchers to easily retreat or change position. However the reverse speed is very poor and it should be taken into consideration, while the armour is decent, the Excelsior is a very large target and will easily be spotted from far away.

Usage in battles

The A33 Excelsior is a fast moving highly manoeuvrable, well armoured heavy tank offering great speed of up to 40 km/h. It excels at flanking and catching the enemy of guard. To get the best from this tank in battle, use it speed and manoeuvrability to your advantage. Since the Excelsior is a heavy tank it armour offers up to 114 mm of protection and if angled it can further increase it to offer over 210 mm. Allowing the tank to become immune to virtually all enemy rounds. However, the thickest parts of the armour plate is on the front of the tank and front of the turret, so it is important to keep the front pointed towards the enemy in combat.

Combined with the 75 mm cannon, which has a reload of up to five seconds, it is able to cause mayhem on the battlefield. load M61 Shot round and fire away, always aim for the sides and rear of the enemy tanks, this is the weakest parts, when at range. However, when fighting tiger tanks get as close as you can, approach from the rear and shoot the rear of the turret, it will knock the tigers turret out allowing you to head to its side and knock it out with some precision shots.

The A33 Excelsior, does not have any turret mounted machine guns, its roof armour is only 25 mm thick allowing enemy aircraft to cause havoc. To evade the aircraft use smoke and head towards any additional smoke rounds which you may fire, this will prevent the aircraft from following you and allowing you to evade them.

Pros and cons

Pros:

  • Decent front armour thickness
  • Quite fast
  • Hull machine gun works
  • -12 degrees of gun depression
  • Access to smoke

Cons:

  • Front armour is not sloped
  • Large ammo rack in turret ring makes for easy detonation
  • Very slow reverse
  • Shells have no HE filler
  • Weak side armour

History

Prompt

The early combat experience of the Churchill infantry tank raised concerns on its reliability and speed, with a suggestion that production be halted while development focus on an "universal tank" for the British armoured forces to replace the cruiser and infantry tanks. However, until such a design could be formulated, they still needed a tank for the assault role the infantry tanks would take.

Rolls-Royce Company, the company producing the prototype A27 Cromwells, suggested that the Tank Board use the A27 as an interim design with stronger armour, suspension, and armament. The suggestion was supported with the English Electric Company, whom plan to upgrade the A27 with thicker armour and elements from the American M6 heavy tank.

Development and Cancellation

On 07 May 1942[1], Tank Board approved for the production of these uparmoured A27 under the designation A33, though it would also have the name Excelsior. English Electric Company were in charge of producing the uparmoured A27 models and produced two prototypes. The first had the M6 suspension system and a 6-pdr cannon. The second had a wider track, different armoured skirts, additional frontal armour, and a 75 mm gun. Both used the same V12 Meteor engine as the A27.

Reliability issues with the Churchill were soon ironed out by 1943, to the point it became a very successful infantry support vehicle and multiple variations were made based off the chassis. The A33 Excelsior, meant to replace the Churchill, was no longer needed and the project was dropped in 1943.

Today, the second prototype can be seen at the Bovington Tank Museum.
