This is an injection-plastic aircraft model kit.
From the manufacturer:
The Boulton-Paul Defiant holds a unique place in British aviation history as the only 'turret fighter' to enter service with the RAF. A contemporary of the only other turret fighter, the Royal Navy's Blackburn Roc, the Defiant used the philosophy that a fighter aircraft, armed solely with a turret bristling with machine guns, would be able to enter a bomber stream causing havoc and that the turret would also enable it to defend itself from enemy fighters.
However, despite the sleek lines of the aircraft and its powerful Merlin engine, the Defiant proved to be a failure in the role of daylight interceptor. During its first few engagements during the Battle of Britain in 1940, enemy pilots were taken by surprise and the Defiant fared well. But soon the Luftwaffe pilots worked out its weaknesses, especially the lack of forward firing guns, which meant head-on attacks from enemy fighters were often fatal.
The Defiant was soon relegated to night fighting duties where it fared better, before being eventually re-assigned to Air Sea Rescue work and training duties.
Upon completion, this model measures 225mm long and 250mm wide.
