The Sud-Ouest Espadon (en: Swordfish) was a post-war prototype French interceptor designed and built by SNCASO. Only four aircraft were built and the type did not go into production. Espadon prototypes were used as testbeds for auxiliary rocket engines.
The Heinkel 119 was designed by the Günter brothers and exemplified their belief in streamlining. Powered by a DB 606 engine, the pre-war aircraft did not find a niche in a reconnaissance or bomber roll.
