Interest in the HP.52 by the Swedish for placing a potential order led to the HP.53 prototype, which was subsequently used as a testbed for a pair of 1,000 hp Napier Dagger VIII 24-cylinder H-block water-cooled inline engines.
In 1936, the RAF ordered 150 Dagger-engined Hampdens as the Hereford. Problems with engine cooling resulted in most of those built (by Short & Harland) being re-engined as Hampdens. The surviving Herefords served in training units only.
The engines were unreliable, over-heating on the ground and cooling too rapidly when airborne, while the very high pitched exhaust note proved uncomfortable for the crews.
