Design and development

The Bo-T was a biplane powered by two 164 kW (220 hp) Hispano-Suiza 8Ba inline piston engines and fitted with twin floats.[1] It had room under the fuselage for a torpedo.[1] The prototype was destroyed on the first flight in August 1916 but the French Navy still placed and order for 91 aircraft.[1] Deliveries did not start until 1917 and were stopped when the Armistice was signed.[1] Only a few aircraft saw operational use on coastal patrols in the mediterranean.[1]

In 1919 a ten-passenger transport variant was flown designated Bo-C/Bo.20 but it was destroyed during testing.[1]
