The Avro Type 584 Avocet was a British single engined naval fighter prototype designed and built by Avro. While the Avocet was not built in numbers, one of the prototypes was used as a seaplane trainer for the Royal Air Force's (RAF) High Speed Flight.


Design and development

The Avro 584 Avocet was designed by Avro's chief designer, Roy Chadwick to meet the requirements of Specification 17/25 for a Naval fighter[1]. It was a single engined, all metal biplane, powered by a 230 hp Armstrong Siddeley Lynx engine and having interchangeable wheel and float undercarriages. Although it did not have folding wings, it was designed to be easily dismantled for storage onboard ship.

Two prototypes were built, the first flying as a landplane in December 1927 and the second prototype flying as a seaplane in April 1928[1]. Both prototypes were evaluated for the Fleet Air Arm at RAF Martlesham Heath, where owing to the low powered engine, the performance was seen to be unimpressive[2], and so was not ordered into production.

Operational history

Although no production occurred, the second prototype was used by the RAF's High Speed Flight at Calshot as a seaplane trainer for Schneider Trophy pilots[2].
