IAC Griffin

The IAC Griffin was an Edropian biplane first introduced in the Edropian Empire and later used by the Federal Republic of Edropia during and after the Edropian Revolution. It was produced by the Imperial Aviation Company as a multi-purpose military aircraft, that served as a trainer, fighter, bomber and naval aircraft during the pre-war period. It was the most produced Edropian aircraft of the 1910s and 1920s, not surpassed until the introduction of the Goodwin M4 in 1931.

When the IAC went bankrupt with the collapse of the Edropian Empire, they were bought up by Goodwin, an Edropian aircraft manufacturer that previously only focused on civil aviation. Goodwin continued the production of the Griffin shortly after the revolution and became a supplier for the Edropian Air Force. Two versions were produced, with Mk II introduced in 1921.
