Blackburn Roc

During the inter war period, the Air Ministry pinned high hopes on two rather unusual fighters. The Boulton Paul Defiant and Blackburn Roc were single engined monoplanes built for the Royal Air Force and Fleet Air Arm (the Royal Navy’s air force), respectively. Both aircraft concentrated their armament of 4×7.62mm (.303inch) machine guns in an electrically driven turret behind the pilot. The Roc was envisioned as a mobile observation post, engaging “fleet shadowing” aircraft that could report on ship movements whilst staying beyond the range of AA guns, or breaking up incoming torpedo and dive bomber attacks. It was also designed with a limited dive bombing capability of its own In theory, the idea was sound. Two seater fighters such as the Bristol Scout had given excellent service in World War One, and had been a staple of the RAF in the inter war period. This arrangement would allow the pilot to concentrate on flying whilst his gunner could worry about firing, and also provide a defense against the classic diving attack. Once again, however, when faced with the harsh reality of modern war, it was exposed as a liability. The only way the gunner could get aim at an opposing fighter would be if the pilot flew straight and level, which in a dogfight is the very last thing you want to do. The aircraft lacked any forward firing guns, and the turret could not even fire head on. The Browning 7.62mm (.303 inch) was the standard RAF weapon for much of the war, but the rifle calibre bullets lacked stopping power against modern aircraft. It also proved almost impossible for the gunner to bail out of a stricken aircraft. The Defiant saw far more combat and suffered very heavy losses once its Achilles Heel was discovered. However there is a reason the Roc is on the list and the Defiant isn’t. Despite the losses, the RAF’s version scored some early success and proved a reasonable night fighter during the early stages of the Blitz. The Roc on the other hand had a top speed of 160 kph (100mph) less, making it slower than most of the German bombers it was supposed to be shooting down. As a fighter it failed utterly, and in its career scored a grand total of one confirmed kill. The most useful task the Roc ever performed were the four examples parked up and used as permanent AA posts at Gosport airfield.
