HF.20 Role Reconnaissance aircraft Manufacturer Farman Designer Henri Farman First flight 1913 The Farman HF.20 and its derivatives were a family of reconnaissance aircraft produced in France shortly before and during the First World War. It was a refined version of the Farman MF.11 "Shorthorn" that did away with the type's distinctive landing skids and incorporated design features from Henri Farman's designs. It entered service with the French Belgian and Serbian armies in 1913 (two aircraft conducting reconnaissance during the Siege of Shkoder in the First Balkan War with one crashing), and with the British RFC and RNAS shortly after the outbreak of war. The type was also licence-built in the UK by Airco and Grahame-White.
The HF.20 was seriously underpowered, and a variety of engines were trialled in the hope of correcting this, none with much success. The problem was eventually solved only when an engine of twice the power of the original powerplant was fitted to the HF.27 variant, by which time the aircraft was already obsolete. Nevertheless, the performance of this machine made it adequate for use on secondary fronts.
