Agusta Bell Sioux AH Mk1

The Sioux, affectionately referred to as the 'clockwork mouse', was distinctive for its bubble canopy, exposed welded tube tail boom and saddle fuel tanks. Its two bladed rotor made a 'chop-chop' sound, leading to the nickname 'chopper' for helicopters.

The Sioux is probably the best known of the early military helicopters earning its reputation during the Korean war (1950-1953). It is the most recognised, perhaps due to the success of the 1970 feature film, based on the 1968 novel M*A*S*H (Mobile Army Surgical Hospital) by Richard Hooker and the long-running television series.

The Sioux was the first of many helicopters within the US Army to be named after Native American tribes.
