Description
The Mk.VIII torpedo is a British 21-inch (533 mm) torpedo mounted on many destroyers and motor torpedo boats in the British tech tree. Other 21-inch British torpedoes include the Mk.V (533 mm) and the Mk.IX (533 mm).

General info
The Mk.VIII torpedo has a diameter of 533 mm, a length of 6.579 m, and weighs 1,566 kg. Without the Torpedo Mode modification installed, it can travel at a maximum speed of 84 km/h for 4.57 km. With it installed, the maximum range is increased to 6.40 km, but the maximum speed is reduced to 76 km/h.

Effective damage
The Mk.IX torpedo carries a 340 kg TNT warhead, which is fairly middling compared to other torpedoes. Destroyers and other smaller vessels can be destroyed by a single hit, but cruisers, especially heavy cruisers, may be able to survive multiple hits, depending on where the hit occurred.
Comparison with analogues

With the Torpedo Mode modification installed on both, the G7a has a much higher maximum range (14 km), but it has a much lower maximum speed (56 km/h).
- 53-38 (533 mm): The 53-38 has a slightly lower maximum speed (82 km/h), has a lower maximum range (4 km), and has a smaller explosive charge (300 kg TNT equivalence). With the Torpedo Mode modification installed, the 53-38 has a much higher maximum range (10 km), but it has a much lower maximum speed (56 km/h).

Usage in battles
The Mk.VIII is a fast torpedo, sporting an above-average top speed of 84 km/h with the Torpedo Mode modification and a top speed 76 km/h without. However, its maximum range is small, 4.57 km with and 6.4 km without the Torpedo Mode modification. Its warhead is also only average, at 327 kg TNT.
For motor torpedo boats and other smaller vessels, the Mk.VIII should be used without the Torpedo Mode modification, where the lower maximum range is insignificant in the often short-range engagements, and the higher maximum speed is helpful in making it more difficult for the enemy vessel to evade. On destroyers, the Mk.VIII should be used with the Torpedo Mode modification, since close-range encounters are much less common, and the increased maximum range provides more strategic usefulness, especially in Encounter and Enduring Confrontation game modes, though in this aspect, its small range of 6.4 km leaves much to be desired.
Pros and cons
Pros:
- Above average maximum speeds
Cons:
- Short maximum range
History
The 21-inch Mark VIII torpedo was designed in 1925. It had a diameter of 21 inches (533 mm), a length of 21 feet 7 inches (6.579 m), weighed 1,566 kg, and carried a 340 kg TNT warhead. The Mark VIII was the first British torpedo to utilise the burner-cycle engine, an advancement in torpedo technology at the time. In the burner cycle engine, pressurized air was heated and combined with atomised fuel, and then injected and ignited into the combustion chamber at top dead centre (when the piston is furthest away from the crankshaft). Powered by this, the Mark VIII could maintain a speed of 40 knots (74.1 km/h) for 4.57 km.
An improved version Mark VIII** was also developed, which increased the top speed to 45.5 knots (84.3 km/h) and introduced a low-speed setting at 41 knots (75.9 km/h) for 6.4 km. As originally designed, the Mark VIII** carried a 327 kg TNT warhead, though this would be replaced by a 365 kg Torpex warhead in later productions.
The Mark VIII entered service and production in 1927. The Mark VIII** was the primary version used during World War II, mounted on motor torpedo boats and the O-class submarines, as well as any succeeding submarine classes. It remained in service within the Royal Navy as late as 1982, when HMS Conqueror sunk the Argentinian light cruiser ARA General Belgrano during the Falklands War, and would continue to remain in service with other minor navies even further.
