The Bristol Babe was a British-built light single-seat biplane, intended for the private flyer and produced immediately after the First World War.

It was aimed at the private owner flyer and was a small single-engined single-seat biplane with unswept staggered single-bay wings of unequal span.

[3] The cockpit was below the upper wing trailing edge with rounded decking aft to the tail.

A possible alternative was the 40 hp (30 kW) flat-twin Siddeley Ounce currently being developed, so a third Babe was begun as a testbed.

Though it was useful for testing, the old Viale was not reliable enough for sale, so following discussions at the Paris Aero Show in November 1919, two seven-cylinder 60 hp (50 kW) Le Rhône Type 7B2 rotary engines were ordered for the first two Babes.
