Port Victoria

P.V.7 (Grain Kitten). Designed specially for anti-Zeppelin operations from small naval craft, this tiny single-seat biplane of 1917 had a single Lewis gun above the centre-section, the trailing edge of which was cut away for elevation. Three drums of ammunition were specified.

  To meet a requirement for a diminutive lightweight single-seat airship interceptor suitable for operation from platforms on relatively small seagoing vessels, the Depot produced the P.V.7 to the designs of W H Sayers. To become known as the Grain Kitten to distinguish it from a competitive design created by the RNAS Experimental Flight at Eastchurch (which accordingly became known as the Eastchurch Kitten), the P.V.7 was an extremely small sesquiplane intended to be powered by a 45 hp geared ABC Gnat two-cylinder air-cooled engine. Armament consisted of a single 0.303-in (7,7-mm) machine gun mounted above the wing centre section. Unavailability of the geared Gnat engine led to installation of a 35 hp direct-drive Gnat with which the P.V.7 was completed in the summer of 1917. Difficulties were experienced with the engine from the start of flight testing in June, the aircraft being tail-heavy and performance disappointing. A series of modifications was introduced, but the P.V.7 was not flown subsequently.
