The Loening XS2L was an American biplane scout amphibian developed by Keystone-Loening (then a subsidiary of Curtiss-Wright), for the United States Navy during the early 1930s.

Design and development

In the early 1930s the Navy became interested in exploring amphibious capabilities for its cruiser-based observation and scout floatplanes to remedy the problem of periodically having to rig the wheeled undercarriage and then revert to floats. After some experiments, installing retractable landing gear into the existing types' floats was ruled out due to degradation in performance. A purpose-built amphibian, however, was viewed as a potentially better solution. [1]

Three companies – Great Lakes, Keystone-Loening and Sikorsky - submitted aircraft to meet the Navy's requirements, with their designs designated XSG-1, XS2L-1 and XSS-1 respectively. The Loening's entry was a conventional biplane that featured flying boat hull, retractable main landing gear and a single R-985 Wasp Junior engine in a nacelle on the upper wing. The pilot and observer were seated in an enclosed cockpit that also encompassed some of the interplane struts, resulting in a curiously shaped glazing area.

The XS2L-1 was delivered for official trials in February 1933. Although it showed marginally better performance than its rivals, it still offered no considerable advantages over the existing floatplanes like the Vought O3U-3 and Berliner-Joyce OJ-2, and no production resulted. [1]

<span class="mw-page-title-main">Amphibious aircraft</span> Aircraft able to land / take off from both land and water

An amphibious aircraft, or amphibian, is an aircraft that can take off and land on both solid ground and water. These aircraft are typically fixed-wing, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared with planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up.

The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear.

The Grumman J2F Duck is an American single-engine amphibious biplane. It was used by each major branch of the U.S. armed forces from the mid-1930s until just after World War II, primarily for utility and air-sea rescue duties. It was also used by the Argentine Navy, who took delivery of their first example in 1937. After the war, J2F Ducks saw service with independent civilian operators, as well as the armed forces of Colombia and Mexico.

The Curtiss SO3C Seamew was developed by the Curtiss-Wright Corporation as a replacement for the SOC Seagull as the United States Navy's standard floatplane scout. Curtiss named the SO3C the Seamew but in 1941 the US Navy began calling it by the name Seagull, the same name as the aircraft it replaced, causing some confusion. The British Royal Navy kept the Curtiss name, Seamew, for the SO3Cs that they ordered. One of the US Navy's main design requirements was that the SOC Seagull's replacement had to be able to operate both from ocean vessels with a single center float and from land bases with the float replaced by a wheeled landing gear.

The Friedrichshafen FF.31 was a two-seat prototype German maritime reconnaissance floatplane built by Flugzeugbau Friedrichshafen during the First World War. Although primarily intended for reconnaissance duties, the aircraft was provided with a machine gun to engage other aircraft. Although it was satisfactory for its intended mission, it lacked the performance necessary for use as a fighter. A pair of aircraft were built in 1915 and it was not accepted for production by the Imperial German Navy's Naval Air Service.

The Fokker F-11 was a luxury flying boat produced as an 'air yacht' in the United States in the late 1920s. Technically the aircraft was the Fokker Aircraft Corporation of America's Model 9. It was sold in North America as the Fokker F-11 and was offered in Europe as the Fokker B.IV. By the time the first six aircraft had been constructed, it was already evident that the design was not going to sell well. A few were sold, two to notable multi-millionaires; Harold Vanderbilt and Garfield Wood each purchasing one. One was bought by Air Ferries in San Francisco. The F-11A cost $40,000 but the price was slashed to $32,500 as the depression set in during 1930. The F-11 was a commercial failure.
