Development
The company designed the Elias EM-1 to meet a
United States Marine Corps requirement for a multi-role 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 300hp (224kW) 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 (designated EM-2) all had the equal-span wings and were powered by a 400hp (298kW) Liberty 12 inline engine.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 re-designated EO-1.Variants
