About the BOEING E75N1
The BOEING E75N1, commonly known as the Stearman Model 75, is a biplane designed in the 1930s for primary training missions. Manufactured by the Stearman Aircraft Division, which later became part of Boeing, the aircraft holds a significant place in aviation history due to its role during World War II. The E75N1 designation refers to the model utilized primarily by the Navy for advanced flight training, distinct from the Army variants known as PT-13, PT-17, and PT-18.
First flown in 1934, the Stearman Model 75 became an integral part of the military training program, providing thousands of pilots with the necessary skills to advance to more complex aircraft. The Navy adopted this model due to its robust construction, intuitive controls, and reliable performance, making it an ideal platform for rookie aviators. The versatility of the aircraft allowed it to perform various duties beyond training, including crop dusting, aerobatic displays, and even mail delivery post-war.
Key Features and Capabilities
Production of the Stearman Model 75 lasted from the mid-1930s through 1945, with Boeing producing over 10,000 units. The aircraft's simple yet effective design featured a conventional landing gear, a fabric-covered wooden and steel airframe, and a distinct open cockpit layout, which offered excellent visibility and a pure piloting experience. It was equipped with different engines over its production run, including the Continental R-670 and Lycoming R-680, each offering reliable power for consistent training operations.
The Stearman Model 75's legacy endures not just in its wartime service but also in its post-war civilian life. Many surplus planes were sold to the public, finding new careers in aerial spraying and flight instruction. Restored Stearmans are now prized by collectors and aviation enthusiasts. The iconic design, ease of handling, and historical significance make the BOEING E75N1 a celebrated and enduring symbol of aviation training excellence.
