The Cox-Klemin XS was a 1920s American experimental scout biplane, the first aircraft to be launched and recovered from a submarine.
Based on a design by the US Bureau of Aeronautics for a simple single-seat scout seaplane that could be disassembled and assembled quickly. Instead of building the aircraft itself the Bureau of Aeronautics contracted the Cox-Klemin Aircraft Corporation to build six aircraft designated XS-1. The aircraft were powered by a 60 hp Lawrance L-4 radial engine. One aircraft was re-engined in 1923 with a Kinner engine and re-designated XS-2.
As part of a series of studies conducted by the United States Navy after World War I into the possibility of submarine borne observation and scouting aircraft, the submarine S-1 became the experimental platform for this project late in 1923. The XS-1, XS-2 and the Martin MS-1 were used for the trials mounted in a cylindrical pod behind the conning tower. After surfacing the aircraft could be rolled out and assembled, it was then launched ballasting the sub until the deck was awash. The first full cycle of surfacing, assembly, launching, retrieving, disassembly, and submergence took place on 28 July 1926, on the Thames River at New London using the XS-2.
After further trials during 1926 all the experimental aircraft were scrapped.

USS S-1 (SS-105) was the lead boat of the S class of submarines of the United States Navy. The Navy had awarded contracts for the first three S boats under the same general specifications but of different design types. S-1 was what was known as a "Holland-type", while S-2 was a "Lake-type" and S-3 a "Government-type".
A submarine aircraft carrier is a submarine equipped with aircraft for observation or attack missions. These submarines saw their most extensive use during World War II, although their operational significance remained rather small. The most famous of them were the Japanese I-400-class submarines and the French submarine Surcouf, although small numbers of similar craft were built for other nations' navies as well.
The Curtiss SBC Helldiver was a two-seat scout bomber and dive bomber built by the Curtiss-Wright Corporation. It was the last military biplane procured by the United States Navy. Delivered in 1937, it became obsolete even before World War II and was kept well away from combat with Axis fighters.
The Hall XPTBH was a prototype American twin-engined seaplane, submitted to the United States Navy by the Hall Aluminum Aircraft Corporation in response to a 1934 specification for new bomber and scout aircraft. Constructed in an innovative fashion that made extensive use of aluminum, the XPTBH proved successful in flight testing, but failed to win favor with the U.S. Navy. No production contract was awarded, and the single aircraft built served in experimental duties before its destruction in a hurricane during 1938.
The Nakajima E4N was a Japanese shipboard reconnaissance aircraft of the 1930s. It was a two-seat, single-engine, equal-span biplane seaplane used primarily by the Imperial Japanese Navy.
The Nakajima E8N was a Japanese ship-borne, catapult-launched, reconnaissance seaplane of the Second Sino-Japanese War. It was a single-engine, two-seat biplane with a central main-float and underwing outriggers. During the Pacific War, it was known to the Allies by the reporting name "Dave".
The Waco Aircraft Company (WACO) was an aircraft manufacturer located in Troy, Ohio, United States. Between 1920 and 1947, the company produced a wide range of civilian biplanes.
The Grumman XSBF, also known by the company designation G-14, was an American biplane scout bomber developed by Grumman Aircraft for the United States Navy during the 1930s. Derived from Grumman's successful "Fifi" fighter, the aircraft was developed at a time when the biplane was giving way to the monoplane. In competition against other aircraft it proved to possess inferior performance in its intended role, and did not enter production. The sole prototype went on to serve as a liaison aircraft, as well as being used in experiments by NACA, before being destroyed in a crash in 1939.
The Martin BM was a 1930s American torpedo bomber built by the Glenn L. Martin Company for the United States Navy.
The Savoia-Marchetti S.56 was an Italian single-engine biplane flying boat trainer and tourer, built by Savoia-Marchetti.
The Kinner Airster is an American two-seat single-engined biplane designed by Bert Kinner and built by his Kinner Airplane & Motor Corporation.
The Yokosuka K4Y was a Japanese floatplane trainer of the 1930s. A single engined two-seat biplane, 211 K4Ys were built between 1933 and 1940, serving as the Imperial Japanese Navy's basic floatplane trainer throughout the Second World War.
The Caspar U.1 was a 1920s German patrol seaplane designed by Ernst Heinkel and built by Caspar-Werke. The U.1 was designed to fit into a cylindrical container to allow it to be carried, then launched from a submarine.
The Aichi E8A was a prototype Japanese reconnaissance floatplane of the 1930s. It was a two-seat single engined biplane built for the Imperial Japanese Navy. Only two were built.
The Kawanishi E10K, also known as Kawanishi Type T, Kawanishi Navy Type 94 Transport Seaplane and Kawanishi Navy Experimental 9-Shi Night Reconnaissance Seaplane, was a small Japanese flying boat of the 1930s. It was a single-engined biplane intended to meet a requirement for a night reconnaissance aircraft for the Imperial Japanese Navy, but was not selected for production, the single prototype being converted to a transport and operated as the Navy Type 94 Transport.
The Martin MS-1 was an experimental scout biplane ordered by the United States Navy and was intended to operate from a submarine. It first flew in 1923 and the type was used for tests until 1926 when the project was cancelled.
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 Yokosuka E6Y was a Japanese submarine-based reconnaissance seaplane developed at the Yokosuka Naval Air Technical Arsenal for the Imperial Japanese Navy during the 1920s. The prototype first flew as the Yokosho 2-Go in 1929.
The Heinkel HD 15 was a single-engine biplane seaplane, developed by the German aeronautical company Heinkel Flugzeugwerke in the late 1920s and remained at the prototype stage.
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.
