Another plane from my fictional island nation of Sundria.

The Broadhead is a late WW2 fighter, intended to both push the performance of a prop fighter and also to have potential for conversion to a jet propulsion system. For the propeller, it uses two 2000HP Sinclair Spirit engines, each driving one of the contra-rotating pusher propellers at the rear. With the weight of the engines being concentrated at the rear, the Broadhead uses a tailless delta wing, giving large amounts of lift at the rear and an overall high lift-to-weight ratio. To improve agility, a pitch-control canard is also added at the front, with a degree of dihedral to reduce interference between the canard and main wing.
An air-to-air radar system is provided in the nose cone, though this did mean pushing the armament of 8 wing guns out and back to the canard base. Fuel is carried in the main fuselage, and gives the Broadhead an excellent range, especially as the high-lift design allows it to cruise at 40% throttle. The emphasis on lift also shapes the combat doctrine developed for the Broadhead. It is intended to gain the altitude advantage over its opponents, then use boom-and-zoom tactics. As it can achieve 460mph in level flight, and 600mph in a power dive, it's unlikely any opponent could react quickly enough to respond. However, these trials by combat never took place. The Broadhead was developed too late in the war, and manufacturing was too slow for them to be deployed in worthwhile numbers. A relatively small order was completed as both a backup if jet introduction proved more problematic than anticipated, and also as testbeds for trialling jet technology on fighters.
