This week's plane is the wonderful Boulton Paul Defiant (nicknamed Daffy) a turret fighter designed as an interceptor but after initial success, notably over Dunkirk, the Defiant was found to be vulnerable to the German Bf 109. The Defiant then switched to night-fighting duties before moving on to use in air-sea rescue, air radar and target tug capacities.

Defiant ASW Mk I, 276 Air-Sea Rescue Squadron 1942
And apologies to purists but I couldn't resist including this:
