Blackburn B-25 Roc

The Blackburn B-25 Roc was a British Second World War era Fleet Air Arm fighter aircraft.

Derived from the Blackburn Skua and developed in parallel, the Roc had its armament in a turret.

The Roc came to be viewed as inferior to existing aircraft such as the Skua and the type had only brief front line service.
