Истребитель "Рок" I из 778-й эскадрильи, 1940 г.
Blackburn Roc L3084. This two-seat Fleet trainer first entered FAA service in February 1940, with 806 Sqn at Eastleigh. The type ended its days as a target tug and trainer and the last examples were retired in August 1943. Powered by a 890 h.p. Bristol Perseus XII radial engine, the Roc had a range of about 480 nautical miles.
Structurally similar to the Skua, the Roc had a widened fuselage to accommodate the Boulton Paul gun turret and the mainplane had 2 deg dihedral outboard of the centre section.

The Roc was intended to meet Specification 26/36 as a twin-float seaplane fighter. Seen here is one of the two trials machines, L3059, after being fitted with floats at Blackburns Dumbarton factory in October 1939. L3059 is painted with camouflaged upper surfaces and sky on the lower half of the fuselage and underside of the starboard wing. The underside of the port wing was painted black. Roc L3059 was water-tested at Helensburgh, not far from the Dumbarton factory. The trials were not successful and the aircraft crashed while taking off on December 3, 1939.

Roc L3084 was later converted to a target tug. The idea of a turret fighter bringing its guns to bear in broadside attacks proved unsound and Rocs were used as fighters only briefly. Relegated to target-towing duties, most Rocs had disappeared by the summer of 1943.

There were no special prototypes of the Blackburn Roc and the first aircraft, L3057, was first flown on December 23,1938, by Flt Lt H. J. Wilson. After contractor's trials at Brough, L3057, in company with L3058 and L3059, went to A&AEE Martlesham for handling and armament trials.
