This company built bombers to designs of the Section Technique de I'Aeronautique, 1916-1918, as the Establissements Letord at Chalais-Meudon. The last of these aircraft to be developed was intended as a night bomber. It was in the same class as the Handley Page bombers, with a wingspan of 25.91m. In 1923 Letord built an experimental aircraft for the government, which was evolved by Becherau, designer of the prewar Deperdussins. In 1925 part of the works was let to Villiers, which built racing aircraft and the small Albert biplane produced under license of Tellier-Duhamel.
