The FV215b (183) is a British tier 10 premium turreted tank destroyer

Project for a heavy SPG based on the Conqueror Mk II tank with a 183 mm gun and rear placement of the traversable turret and fighting compartment. The vehicle was designed to counter Soviet heavy tanks at long range (up to 1,829 m) and should have been able to withstand return fire from 122 mm guns at a distance of up to 500 m. After the development of 193 mm Malkara anti-tank rockets—which were a cheaper and more efficient choice for countering the IS-series tanks—the vehicle lost its relevance. The project was canceled shortly after a dummy vehicle was built.

Assault tank based on the Conqueror chassis with a 183mm gun mounted on it. The project was cancelled in the 1950s and it never saw military service.

Known as the "Death Star", this tank destroyer is well-known for its apocalyptic gun. Especially when loaded with premium shells, this monster is a death sentence to any tank and you must avoid frontal combat with this tank at all costs unless it's reloading.

As a downside, the FV215b (183) can only turn its turret 45 degrees either direction. The gun has a horrific load time and low ammo capacity, comparable to SPGs, and is not very accurate. So as long as you can outmaneuver its gun range you will be able to destroy it.

The FV215b (183) is replaced by the FV217 Badger turretless tank destroyer and become itself a special vehicle.

FV215b (183)

Pros and Cons

Pros:
- Unbelievable raw gun statistics: mind-boggling damage-per-shot, tied with FV4005 for the best basic ammo penetration in the game

- Also tied with FV4005 for the largest gun caliber of all non-SPGs (183mm), Allowing to overmatch any tanks with sloped armor (Swedish TD for example)

- HESH Premium rounds with the damage of an artillery; can one-shot many Tier IX and below tanks

- Very wide fire arc vs other British TDs or even TDs in general, Although its turret is not fully traversed.

- Excels at peek-a-boom while sidescraping due to decent armor and rear-mounted turret

- Fantastic turret armor

- Thanks to 9.21 patch, now it had acceptable ammunition storage at 20 shells


Cons:
- Tied with FV4005 for Worst single shot reload time of any TDs in the game (28 second with 100% crew)

- Hull armor is unreliable, Side armor is very weak and not suitable for face-to-face sidescraping

- Poor gun handling: aim time is pretty long, dispersion bloom from any source is extreme; very poor accuracy

- Horrible gun depression, weak side and rear armor, rear-mounted non-fully traversed turret, and horrible reload time makes it very vulnerable from flanking and hit-and-run.

- Extremely poor mobility due to terrain resistance and poor p/w ratio, will never reach top speed unless it's downhill

- Prone to engine fire due fuel tanks placed on front


Performance

This vehicle is very different from its predecessor. The 183mm gun is still immensely powerful(as powerful as the 180mm gun on the Object 261) and has a turret as well. Due to these facts, the vehicle is capable to spread fear and unorganized retreat under its opponents on close and middle distances, making it a quite powerful defensive unit. Nevertheless, these advantages are only useful in urban battlefields, where flanking operations are often unavailable for the enemy due to cover from the own team.

On open and plain maps players should strictly avoid to lead a push in the first few minutes of a round if they do not want to get blown up by artillery fire and flanking medium or light tanks. Furthermore a player should look for good cover, where one can fire from . In case of the necessity of a push always stay in the second row and try to get flank cover from other tanks. If your teammates do not react or even refuse to cover you, try to use the landscape even more in order to avoid as much direct enemy fire as possible. When this is not possible, have an eye on the positions of the enemy and those of your team members and go to positions, from which you have natural cover from your team members (because then they will spot the enemy before they are able to spot you).

Finally, if you have AP loaded, and you have a nice IS-7 in your sights, let the gun crack and see him lose most, if not all of his HP. Also, using gold HESH rounds, the FV215b (183) can easily turn an astray battle entirely in your favor. However, with only 230mm of penetration and a tendency for tracks and other spaced armor prevent penetration, the HESH shell is the ultimate in randomness and can only be used with careful aim or deliberate acceptance of 500 damage per shot. When using HESH avoid the sides of Russian heavies as they have thick spaced armor and always aim for weakspots when faced with the fronts of heavies, TDs, and even some meds and lights (E50/E50M and T54LW respectively) as if you were firing AP to maximize damage dealt and possibly get a penetrating hit and do full damage.
