Designed by Harold Bolas to meet a specification (6/22) for a single-seat shipboard fighter to succeed the Gloster Mars X Nightjar, the Plover appeared in 1922, three prototypes were built.

Of wood and fabric construction, and designed around a 436 hp Bristol Jupiter IV nine-cylinder radial, the Plover could be fitted with either a normal wheel undercarriage or with twin floats from which wheels projected to provide amphibious capability.

Armed with two synchronised 0.303-in (7,7- mm) guns, the Plover was ordered into small-scale production, ten were built of which at least six served briefly with Fleet Fighter Flights, before being superseded by the superior Fairey Flycatcher.

Parnall and Sons of Bristol initiated work on the company’s first original aircraft, a single-seat anti-airship fighter to the designs of A Camden Pratt, in 1916. Intended to meet a requirement formulated by the Admiralty, this aircraft, unofficially known as the Zeppelin Chaser, was a large, two-bay staggered biplane of wooden construction. It was powered by a 260hp Sunbeam Maori 12-cylinder water-cooled engine and armed with a single 7.7mm gun offset to starboard and firing upward at an angle of 45 degrees. Two prototypes were ordered, but the first of these proved appreciably overweight. Although the Scout reportedly flew twice, it was considered to possess unacceptably low safety factors and was returned to the manufacturer, development being abandoned.
