Design and development
The H.V.220 was an all-metal single-seat cantilever monoplane with twin floats and powered by a 2,200 hp (1,641 kW) Lorraine 12Rcr Radium inline piston engine. The aircraft was completed but problems with the Radium engine were never sorted and the aircraft was not flown ending French hopes of a Schneider Trophy win. An improved variant powered by a Radium engine was planned as the H.V.320 but never built.
