The Spartan 8W Zeus was a prototype military aircraft trainer built by Spartan Aircraft Company in the United States in 1937. It was based on the airframe of the Spartan Executive civil aircraft. The sole airframe produced was designated serial number 8W-1 and was registered as NX17612 [2]
The Spartan 8W Zeus was a conventional low-wing monoplane of metal construction, with a semi-monocoque fuselage and a cantilever wing. [3] Designed as a two-place trainer, the 8W drew heavily from the design of the Spartan Executive . The wing, undercarriage, and lower half of the fuselage are essentially a modified 7W structure. The upper half of the fuselage was redesigned from a 4-5 place enclosed cabin into a tandem-seat, glazed cockpit with sliding canopies. The tail was also identical to that of the 7W. The main units of the tailwheel undercarriage were retractable. [4]
The Spartan 8W Zeus was powered by a 600 hp (447 kW) Pratt & Whitney Wasp engine. [5]
The intended purpose of the Zeus was to offer an advanced trainer for military use. After production of the prototype, the airplane was marketed, without success, to the United States Army Air Corps. As a follow-up to those marketing efforts, the prototype was flown to Glendale, California in 1939 for further evaluation by the military. Again, there were no orders generated by that evaluation and the Zeus returned to the factory in Tulsa, Oklahoma in 1940. [4]
The final role of the prototype Zeus was as training tool for students at the Spartan School of Aeronautics. [6]
A concept model was introduced in an information brochure that portrayed a combat version of the 8W Zeus, with armament. The FB in the designation indicated Fighter-Bomber. No FBW-1's were ever produced. [4]

The Grumman F3F is a biplane fighter aircraft produced by the Grumman aircraft for the United States Navy during the mid-1930s. Designed as an improvement on the F2F, it entered service in 1936 as the last biplane to be delivered to any American military air arm. It was retired from front line squadrons at the end of 1941 before it could serve in World War II, and replaced by the Brewster F2A Buffalo. The F3F, which inherited the Leroy Grumman-designed retractable main landing gear configuration first used on the Grumman FF, served as the basis for a biplane design ultimately developed into the much more successful F4F Wildcat that succeeded the subpar Buffalo.
The Boeing P-12/F4B was an American pursuit aircraft that was operated by the United States Army Air Corps, United States Marine Corps, and United States Navy.
The Grumman XTSF was a proposed twin-engine torpedo scout aircraft, designed by Grumman for the United States Navy towards the end of World War II. Based on the design of the Grumman F7F Tigercat fighter, but enlarged and with the addition of a bomb bay, the XTSF was deemed too large for carrier operations, and the project was cancelled before any aircraft were built. Instead, the Navy chose to order the single-engine XTB3F, which became the successful AF Guardian.
The Spartan Aircraft Company was an American aircraft manufacturing company, headquartered on Sheridan Avenue near the Tulsa Municipal Airport in Tulsa, Oklahoma. Previously known as Mid-Continent Aircraft Company, the company had been reorganized under the Spartan name in 1928 by oil baron William G. Skelly—and operated until 1961, manufacturing aircraft, aircraft components, and recreational vehicle trailers. The company was known for the luxurious Spartan Executive aircraft produced in the late 1930s and early 1940s.
The Spartan 7W Executive is a cabin monoplane aircraft that was produced by the Spartan Aircraft Company during the late 1930s and early 1940s. The 7W features an all-metal fuselage, as well as a retractable undercarriage. The 7W Executive was popular with affluent buyers worldwide.

The Martin T4M was an American torpedo bomber of the 1920s. A development by the Glenn L.

The Great Lakes XSG was an amphibious observation aircraft developed in the United States in the early 1930s for a US Navy competition. It was an ungainly and unorthodox biplane design with a single large pontoon mounted below the lower wing. This pontoon extended rearwards and carried the conventional empennage. On top of the lower wing, where the fuselage would normally be located, was a stubby nacelle containing the tractor-mounted engine and the pilot's cockpit. The rear of this nacelle was semi-enclosed with glazing and incorporated a position for a tail gunner. The main units of the wheeled undercarriage retracted into the sides of the central pontoon.
The Boeing AT-15 was an American twin-engined bomber crew trainer designed and built by Boeing's Wichita Division. Only two prototypes, designated XAT-15, were built. Plans to build over 1,000 were cancelled on the United States' entry into the Second World War.

The Spartan C5 was a passenger and utility aircraft produced in small numbers in the United States in the early 1930s. It was a further, ultimately unsuccessful, attempt to market the Spartan C4, from which it was developed. Like its predecessor, the C5 was a high-wing, strut-braced monoplane with a fully enclosed cabin. Seating was increased to five places in place of the four seats of the C4. The C5 also incorporated a number of aerodynamic refinements, including a closely cowled engine and spatted mainwheels. The fuselage was constructed of welded steel tube and the wings from wood, and the whole aircraft covered in fabric. The empennage was also mostly constructed from wood, with metal ribs used in the fin and the whole assembly also covered in fabric.
The Vought O4U Corsair was the designation applied to two different experimental biplane scout-observation aircraft. Neither reached production or entered regular service.
