Boeing Model 2

The Boeing Model 2, also referred to as the Boeing Model C and its derivatives were United States two seat training seaplanes, the first “all-Boeing” design and the company’s first financial success.

The success of the Model C led to Boeing’s first military contract in April 1917 and prompted both its reincorporation as the Boeing Airplane Company and relocation from Lake Union, Washington to a former shipyard on the Duwamish River, also in Washington.

The United States Navy bought 51 of the Model C trainers, including the C-1F, and the United States Army bought two landplane versions with side-by-side seating, designated the EA.

The final Model C was built for William Boeing and was called the C-700.
