The Wright-Martin Aircraft Corporation was formed in 1916 to make Hispano-Suiza engines under license. Large numbers of the Model E (the Hispano-Suiza 8Aa) were produced with minor improvements.
The last of the E model engines, the E-4 Tempest was the main product of the new Wright Aeronautical company when it was formed in 1919.
