Elias EM


The Elias EM was a 1920s American general-purpose and marine expeditionary biplane built by Elias.

Development

The company designed the Elias EM-1 to meet a United States Marine Corps requirement for a multirole marine expeditionary aircraft. It was required to operate on either floats or wheels. The EM-1 was a tandem two-seat unequal-span biplane powered by a 300 hp Wright-Hispano H engine. The prototype was modified with equal-span wings and delivered to the Marine Corps in 1922. Six production aircraft were built having equal-span wings, being powered by 400 hp Liberty 12 inline engines.
One production aircraft was delivered to the United States Marine Corps and five to the United States Navy. One of the Navy aircraft was modified as an observation aircraft and redesignated EO-1.
