Out of desperation the Japanese adapted a Ki-61 'Tony' fighter to carry a radial engine resulting in one of the best interceptors used by the Japanese during WWII. It combined excellent power and manoeuvrability but was limited at high-altitudes due to the lack of a supercharger. This is the only example extant and is on display at the RAF Museum Cosford.

The RAF Museum at Cosford has the only surviving, complete example of the Valiant. Indeed, at Cosford one can also see a Vulcan and a Victor, so is the only place where all three British V-bombers are on display.
