The Curtiss 18T Wasp was intended to protect bombing squads along the French coast, and a primary requisite for this job was speed. Speed was not the triplane's only salient feature: an 18T-2 set a new altitude record in 1919 of 34,910 ft (10,640 m). The streamlined and very "clean" fuselage contributed to the aircraft's performance.
The French used the Bleriot XI. 2 BIS. It was a 2 seater.
