The Martin XB-33 Super Marauder was a proposed World War II American bomber aircraft. It was designed by the Glenn L. Martin Company as the Martin Model 190 and was a high-altitude derivative of the company's B-26 Marauder. Two different designs were developed, first as a twin-engined aircraft and then as a four-engined aircraft. The four-engined version was ordered by the United States Army Air Forces, but the program was cancelled before any aircraft were built.
The Vought SBU-1 Corsair was a two-seat, all-metal biplane dive bomber built by Vought Aircraft Company of Dallas, Texas for the US Navy. Its design was based upon the F3U-1 two-seat fighter that was abandoned when the Navy decided not to obtain any more two-seat fighters.

The Curtiss CS was a reconnaissance and torpedo bomber aircraft used by the United States Navy during the 1920s. It was a large single-engine biplane with single-bay unstaggered wings, the design conventional in all respects other than that the lower wing was of greater span than the upper. The CS was built to allow its undercarriage to be quickly and easily interchangeable between wheeled, tailskid undercarriage, and twin pontoons for operation from water. Provision for the carriage of a torpedo was semi-recessed into the underside of the fuselage, blended in behind an aerodynamic fairing. The pilot and gunner sat in tandem open cockpits, while accommodation inside the fuselage was provided for a third crewmember who served as bombardier and radio operator. This station was also provided with a dorsal hatch aft of the gunner's position, and a ventral blister aft of the torpedo recess, which was used for aiming bombs or torpedoes.

The Bellanca XSOE was a prototype American scout observation floatplane built for the United States Navy by the Bellanca Aircraft Company. It was never accepted by the Navy and only the prototype was built.
Naval Aircraft Factory NO was an American short-range reconnaissance/gun spotting aircraft of the 1920s. A single-engined three-seat biplane with alternative floats or wheels, six were built for the U.S. Navy.
The Bellanca SE was an American carrier-based scout monoplane designed and built for the United States Navy by the Bellanca Aircraft Company.
G Elias & Brother was and American manufacturer of cabinets and aircraft based in Buffalo, New York in the 1920s. A.G. Elias sat on the Manufacturers Aircraft Association's board of directors along with President Frank H. Russell, VP Glenn L. Martin, Charles L. Laurence, Chance M. Vought, S.S. Bradley, George P. Tidmarsh, and Donald Douglas. E.J Elias promoted the construction of a Buffalo municipal airport to aid the local fledgling airplane industry of five aviation companies constructing airplanes and airplane parts. From 1920 to 1925, Elias company's chief engineer, David Earle Dunlap (1896-1957), designed the Elias EM-2 Expeditionary planes. He designed the NBS-3 bomber fuselage and the Elias M-1 Mail plane. Dunlap's Elias TA-1 design was the first United States Army Air Corps Trainer to have a radial engine. After tests a McCook Field, the Army Air Corps selected other manufacturers over the Elias bomber and trainer. The company designed the Elias EM-1 to meet requirements for a multirole amphibian marine expeditionary aircraft. Elias delivered six production Elias EM-2 aircraft with Liberty engines to the United States Navy in 1922.
