A 1/7 scale wind tunnel development model of a SNCASO Espadon SO-6025, French, circa 1947-48.

The Espadon (Swordfish) was a single-seater interceptor designed for the French air force, it was developed by the Societe Nationale de Constructions Aeronautiques de Sud-Ouest (SNCASO), under the design leadership of Lucien Servanty.

It flew for the first time on 12th of November 1948 with a Rolls Royce Nene Mk- 100 turbojet built under license by Hispano Suiza. The Espadon lacked power so was uprated by using a under fuselage SEPR 25 auxiliary rocket motor, which ran on a mix of fluraline and nitric acid.

The Espadon was further developed and became the first European aircraft to reach Mach 1 in level flight on the 15th of December 1953, piloted by Andre Turcat.
