What it is

A pilotless aircraft with a gyroscopic autopilot and a preset range, designed in 1917-1918 as an 'aerial torpedo'. Although never used in combat, it paved the way for radio-controlled target aircraft such as the DH.82 Queen Bee, whose name gave rise to 'drone'.

The Hewitt-Sperry prototype (1916-1917) and the Ruston Proctor Aerial Target (1916-1917) compete for the title of first unmanned aircraft; the origin of 'drone' from the 1935 Queen Bee is a common attribution but not the only one.
