The twin-engine F5L was one of the Felixstowe F series of flying boats developed by John Cyril Porte at the Seaplane Experimental Station, Felixstowe, England, during the First World War for production in America.

Porte had taken the Curtiss H-12, an original design by the American Glenn Curtiss, and developed it into a practical series of flying boats at the Felixstowe station. They then took their F.5 model and further redesigned it with better streamlining, a stronger hull using veneer instead of doped linen and U.S.-built 330 hp (later 400 hp) Liberty 12A engines. The prototype was built and tested in England and the design then taken over by the Naval Aircraft Factory, Philadelphia, where further modifications were made to suit their production methods under wartime conditions. [2] The American-built version was also known as the Curtiss F5L and (in civilian operation) as the Aeromarine 75.

The F5L was built by the Naval Aircraft Factory (137), Curtiss (60) and Canadian Aeroplanes Limited (30). Some were converted for civilian use by the Aeromarine Plane and Motor Company in 1919.

Operational history

The F5L entered U.S. service at the end of the war and was the U.S. Navy's standard patrol aircraft until 1928, when it was replaced by the PN-12.

In civil service, named the Aeromarine 75, the Felixstowe F5L could accommodate 10 passengers and was operated by Aeromarine Airways on flights from Key West to Havana, carrying the first U.S. Post Office international air mail on flights from New York City to Atlantic City, and from Cleveland to Detroit. The first in-flight movie screened in an Aeromarine 75 during the Pageant of Progress Exposition, Chicago, August 1921.

A further civil conversion for the Atlantic Coast Airways Corporation of Delaware was reported to accommodate 25 passengers in August 1928, with talkies by First National Pictures run as a test on the inaugural flight. The airline bought about six ex-U.S. Navy aircraft and advertised a service between Montreal, Boston, Newport, New York, Atlantic City, Charleston, Miami and Havana. [3] [4] [5]

On 13 January 1923, the Aeromarine Airways Aeromarine 75 Columbus suffered engine failure during a flight from Key West to Havana and landed in the Florida Strait. Buffeted by 10-to-15-foot (3-to-4.5-metre) waves, its hull began to fill with water. Four passengers died, but the ferry ship H. M. Flagler saved the other three passengers and both crew members.

Survivors

Both a hull and float from a US Navy F5L are preserved at the National Air and Space Museum (Smithsonian). The hull is only partially skinned with wood to reveal structure. Both artifacts are presently in storage and not available for public display. [7]

A flying boat is a type of seaplane with a hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy.

Glenn Hammond Curtiss was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry.

In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines.

<span class="mw-page-title-main">Seaplane</span> Aircraft with an undercarriage capable of operating from water surfaces

A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called hydroplanes, but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed.

The Naval Aircraft Factory (NAF) was established by the United States Navy in 1918 in Philadelphia, Pennsylvania. It was created to help solve aircraft supply issues which the Navy Department faced upon the entry of the U.S. into World War I. The United States Army’s requirements for an enormous quantity of airplanes created a decided lack of interest among aircraft manufacturers in the Navy's requirements for a comparatively small quantity of aircraft. The Navy Department concluded that it was necessary to build a Navy-owned aircraft factory in order to assure a part of its aircraft supply; to obtain cost data for the department’s guidance in its dealings with private manufacturers; and to have under its own control a factory capable of producing experimental designs.

The NC-4 is a Curtiss NC flying boat that was the first aircraft to fly across the Atlantic Ocean, albeit not non-stop. The NC designation was derived from the collaborative efforts of the Navy (N) and Curtiss (C). The NC series flying boats were designed to meet wartime needs, and after the end of World War I they were sent overseas to validate the design concept.

The NC-4 is preserved in the National Museum of Naval Aviation, at NAS Pensacola, Florida.

The Curtiss Model H was a family of classes of early long-range flying boats, the first two of which were developed directly on commission in the United States in response to the £10,000 prize challenge issued in 1913 by the London newspaper, the Daily Mail, for the first non-stop aerial crossing of the Atlantic. As the first aircraft having transatlantic range and cargo-carrying capacity, it became the grandfather development leading to early international commercial air travel, and by extension, to the modern world of commercial aviation. The last widely produced class, the Model H-12, was retrospectively designated Model 6 by Curtiss' company in the 1930s, and various classes have variants with suffixed letters indicating differences.

The Naval Aircraft Factory Giant Boat or GB was a 1919 maritime patrol aircraft project undertaken by the Naval Aircraft Factory (NAF), the in-house aircraft production arm of the United States Navy. The proposed flying boat was larger and heavier and would have possessed a longer range than any similar type then in existence, but the project was hampered by labor and funding shortages stemming from deep post-World War I U.S. military budget cuts, and in 1921, navy leaders prioritized other aircraft types and ended the project. The single incomplete prototype is believed to have been broken up after 1925.
