The Bristol Type 173 was a British aircraft designed in the late 1940s by the Bristol Aeroplane Company. It was a twin-engine, low-wing monoplane primarily intended for military use, specifically as a light transport and utility aircraft. The design featured a spacious cabin and was capable of operating from short airstrips. The aircraft was powered by two Bristol Proteus engines, which provided efficient performance. Although the Type 173 was never mass-produced, it contributed to the development of future aircraft designs and showcased the engineering capabilities of its time.
