The aircraft was a development of the British Hawker Horsley designed for the Danish Navy, but differed in being powered by a radial engine and having a third crew member. Two examples were built in Britain as a precursor to license production in Denmark. Financial constraints meant this was not realised and the Hawker-built examples were the only aircraft produced. They served until the German invasion of Denmark in 1940.
The Avro 571 Buffalo was a prototype British carrier-based torpedo bomber biplane, designed and built by Avro in the 1920s. It was not selected for service, the Blackburn Ripon being ordered instead.

The Bristol Bloodhound was a British two-seat reconnaissance/fighter aircraft designed and built by the Bristol Aeroplane Company as a possible replacement for the Bristol F.2 Fighter for the Royal Air Force. It was unsuccessful, only four prototypes being built.
The Handley Page Hanley was a British torpedo bomber aircraft of the 1920s. A single-engine, single-seat biplane intended to operate from the Royal Navy's aircraft carriers, it was not successful, with only three aircraft being built.
The Handley Page Hendon was a British torpedo bomber of the 1920s. A two-seat development of Handley Page's earlier single-seat Hanley, the Hendon was a single-engine biplane. While six aircraft were purchased by the British Air Ministry for evaluation and trials purposes, no further production ensued and the Hendon did not enter squadron service.
The Blackburn B.T.1 Beagle was a British single-engine, two-seat biplane bomber/torpedo aircraft from 1928. Designed to Air Ministry specifications which led to no contracts for any manufacturer, only one Beagle was built.
The Gloster Goring was a single-engined two-seat biplane designed to meet 1926 Air Ministry specifications for a day/torpedo bomber. It was not put into production and the one aircraft built served later as an engine testbed.
The Bristol Berkeley was built to a British government specification for a single-engine day or night bomber. Three of these two-seat biplanes were built, but no contract for further production was awarded.
