The Vickers Type 131 Valiant was a British general-purpose biplane produced by Vickers in 1927, with the intention of replacing the Royal Air Force's Airco DH.9As, but was unsuccessful, with only a single example built, which was sold to Chile. In 1926, based on experience with the wooden-winged Vickers Vixen biplane, where the wings proved vulnerable to extremes of temperature and humidity, designed a set of metal wings for the Vixen, with which it became the Vickers Vivid, and in parallel, designed an all-metal general purpose biplane, the Vickers Type 131, hoping to replace the DH.9A in that role.
