Development and design

In late 1920, Handley Page started design of a new single seat torpedo bomber to meet the requirements of Air Ministry Specification 3/20 for a carrier based aircraft to replace the Sopwith Cuckoo, in competition with the Blackburn Dart. The resulting design, the Type T, (later known as the H.P.19) and named the Hanley was a single engined biplane of wooden construction. It like the Dart, was powered by a Napier Lion engine and had a crew of one. It had folding three-bay wings which were fitted with full span leading edge slots on both upper and lower wings in order to improve low speed handling. Mason 1994, p.135-136.]

Three prototypes were ordered, the first of which (serialed "N143") flew on 3 January 1922. Barnes 1976, p.219.] Initial testing revealed that performance was disappointing, with low speed handling and the view from the cockpit also poor. Mason 1994, p.136.] After being damaged in a crash landing, the first prototype was rebuilt with new wingtips, a revised two-bay wing and with the control cables for the elevators enclosed in the rear fuselage to reduce drag, flying in December 1922 as the Hanley Mark II. These changes improved performance, but handling was still poor. The third prototype was therefore fitted with revised slots, as well as the drag reduction changes tested on the Hanley Mark II, the revised aircraft being designated Hanley Mark III, demonstrating considerably improved handling. Barnes 1976, p.221-222.]

By the time that the Hanley Mark III was available for testing, the Dart, which was developed from Blackburn's earlier Swift, had already been ordered into service.
