Boulton Paul Defiant Mkl N1801 PS-Y Nightfighter Colmbatore II
Although the Boulton Paul Defiant fought alongside Spitfires and Hurricanes during the air battles above the Dunkirk evacuation beaches and the Battle of Britain which followed, it enjoys nothing of the widespread public recognition its two contemporaries could boast. Surprisingly, the Defiant actually made its first flight and RAF squadron introduction quite some time after both the Hurricane and Spitfire, something which may explain its limited success when used in the day fighter role during WWII. The idea behind the Defiant™s unusual design came from inter-war thinking that future air combat would be fought by fast, heavily armed bomber formations, which would not need the protection of dedicated fighter cover.
In order to combat this, the Defiant, equipped with its quad dorsal turret mounted machine gun armament, could engage these bombers with a beam attack, similar to how battleships might engage, or from below, where the bomber was most vulnerable and where the fighter could concentrate the firepower of its four .303 in Browning machine guns. This same thinking also dictated that this new bomber defence fighter would not need forward firing armament, as the high closing speed of modern monoplane fighters would render frontal attacks useless, so the Defiant incredibly ended up being a fighter aircraft with no forward firing armament at all.Having a similar profile to the Hawker Hurricane which preceded it into service, the Defiant initially scored some significant combat successes against
