Hawker Typhoon

Plane where few things happened.
First of all, it seems that Persha finally gave up with cross-plane equipment. Typhoon, initially armed with 12 machine guns, receives 20mm Hispano Mk. II and finally Mk V.
Both models are researchable on other planes - Mk. II on Hawker Hurricane Mk. II, Mk. V on Spitfire Mk. IX. Everything has to be researched from 0.

Plane itself seems to be average at best. Good rule of thumb is to compare with Corsair - decent multirole fighter. Tornado compared to F4U-1 has 20 km/h lower max speed, but has better dogfighting abilities (turn time and stall speed).
Typhoon comparing to F4U-4 is 40 km/h max speed slower, equal turn time, worse roll rate, higher optimum speed and only lower stall speed. Worse climb ratio and same altitude performance.
Necessity to harvest 28k experience flying with machine guns with really low shell velocity to mount cannons means, that grind is going to be pain.

Finally - it's a sign of lack of love to UK planes.
Exactly as Spitfire line is broken, the same way Persha broke Hawker line.
Tier VIII is the pinnacle of piston fighters design, or an advent of jet planes.
In case of Hawker line it's not.
Ultimate Hawker piston engine fighter was further development of Hawker Tempest - Hawker Sea Fury, as Ta 152 was development of Fw 190.
Instead of that, WG pushed Hawker Hurricane to tier IV and V, at tier V giving tier IV and a half plane OP armament of 4 cannons, that shred to pieces most planes they are point at.
Another screwup is tier VI - Hawker Tornado - failed plane due to engine failure. Same fuselage with different engine (Napier Sabre instead of Rolls Royce Vulture) was named Hawker Typhoon, and fuselage was designed at 1937/38, making planes from 1938 occupy tier VI and VII.
To be aligned with history, Hawker Typhoon should be at tier VI instead of Tornado, then Tempest and Sea Fury. Tier V is debatable, either late model Hawker Hurricane as it is now, or Hawker Tornado, handicapped by failed engine.
