Morane-Saulnier MoS-121

Overview

The Morane-Saulnier MoS-121, also known as the Morane-Saulnier MS.121, was a fighter prototype designed and produced by the French aircraft manufacturer Morane-Saulnier. It was the company's first fighter design after the First World War. The MS.121 was developed in response to the launch of a state-led programme for chasseurs légers or 'light fighters' in the mid 1920s. Many of the features, such as the parasol wing and the undercarriage, largely conformed to Morane-Saulnier’s existing design practices. In order to increase lift and lower landing distances, the pilot could lower the aircraft’s ailerons mid-flight. The fuel tank could also be jettisoned if required. Mixed construction, including multiple types of wood and duralumin, were used throughout the aircraft. During mid-1927, the sole MS.121 prototype performed its maiden flight. Although it underwent official testing, no production aircraft were ever produced. The company terminated the project in favour of other endeavours, such as the Morane-Saulnier MS.221.
