Horton Ho 229 Variants:
H.IX V1 - First prototype, non-powered glider, one built and flown.
H.IX V2 - First powered prototype, one built and flown with twin Junkers Jumo 004B engines. First flight at Oranienburg in January 1945. Gear retraction achieved by early March with top speeds reaching 497mph (800kph). Aircraft lost in landing accident after losing an engine on approach.
H.IXb - (also designated V6 and V7 by the Hortens). Projected two-seat trainer or night-fighter; not built.
Ho 229 V3 - Revised air intakes, engines moved forward to correct longitudinal imbalance. Its nearly completed airframe was captured in production, with two Junkers Jumo 004B jet engines installed in the airframe, and shipped to the United States. Currently stored by National Air & Space Museum.
Ho 229 V4 - planned two seat all weather fighter, in construction at Friedrichroda, but not much more than the tubular framework completed.
Ho 229 V5 - planned two seat all weather fighter, in construction at Friedrichroda, but not much more than the tubular framework completed.
Ho 229 V6 - Projected definitive single-seat fighter version with different cannon, mock-up in production at Ilmenau.
Ho 229 A-0 - Projected expedited production version based on Ho 229 V6; not built.
