The FBA Type A and the similar Type B and C were a family of reconnaissance flying boats produced in France prior to and during World War I.
All three were unequal-span pusher biplane flying boats with a single step hull with ash longerons covered in laminated plywood, divided by bulkheads into eight compartments. The empennage was carried on an upswept curved extension of the hull made from steel tubing. The pilot and observer sat side by side in the open cockpit. [1]
The design originated with patents by Donnet-Lévêque and initially reflected the general configuration of that company's aircraft. The Type A had a single-bay wing, while the larger Type B and C had two bay wings which otherwise only differed in the engine installed, with the type B using a 75 kW (100 hp) Gnome Monosoupape and the type C using a 97 kW (130 hp) Clerget 9B. The RNAS contracted for 20 type B's from Norman Thompson, who was responsible for building flying surfaces for hulls provided from France, which differed most noticeably by having a rectangular all-flying rudder in place of the D-shaped rudder used on French examples. The Type A was the only version with a fin attached to the rudder although some aircraft had a field modification with a fin being added between the hull and the tailplane. The Type H was developed from the Type C but was larger, had a new hull that wasn't attached directly to the tailplane, had an oval rudder and used a Hispano-Suiza 8 stationary engine.
The earliest examples sold entered service with the Austro-Hungarian Navy and Danish Navy prior to World War I, but large-scale use began with sales to the Royal Naval Air Service (RNAS) who initially ordered 20 Type B's from Norman-Thompson before receiving additional Type Cs from France. The French Aéronautique Maritime, and Italian Navy followed with orders for Type Bs and Cs in 1915. The FBA flying boats were used for naval patrols and frequently encountered their opposing German and Austro-Hungarian Navy counterparts which led to some being converted to single seaters armed with a machine gun. Three Type Bs were the first aircraft operated by the Portuguese Navy.

The Sopwith Camel is a British First World War-era single-seat biplane fighter aircraft that was introduced on the Western Front in 1917. It was developed by the Sopwith Aviation Company as a successor to the Sopwith Pup and became one of the best known fighter aircraft of the Great War.
The Nieuport 17 C.1 is a French sesquiplane fighter designed and manufactured by the Nieuport company during World War I. An improvement over the Nieuport 11, it was a little larger than earlier Nieuports and better adapted to the more powerful engine than the interim Nieuport 16. Aside from early examples, it had the new Alkan-Hamy synchronization gear, permitting the use of a fuselage-mounted synchronised Vickers gun firing through the propeller disc.
The Avro 504 was a First World War biplane aircraft made by the Avro aircraft company and under licence by others. Production during the war totalled 8,970 and continued for almost 20 years, making it the most-produced aircraft of any kind that served in any military capacity during the First World War. More than 10,000 were built from 1913 until production ended in 1932.
The Monosoupape, was a rotary engine design first introduced in 1913 by Gnome Engine Company. It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the Monosoupape engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the Monosoupape as "one of the greatest single advances in aviation".
The Sopwith Tabloid and Sopwith Schneider (floatplane) were British biplanes, originally designed as sports aircraft and later adapted for military use. They were among the first successful types to be built by the Sopwith Aviation Company. The "Tabloid", so named because of its small size, caused a sensation when it made its first public appearance.
Grigorovich M-5 was a successful Russian World War I-era two-bay unequal-span biplane flying boat with a single step hull, designed by Grigorovich. It was the first mass production flying boat built in Russia.
The Blackburn TB was a long-range twin-engined anti-Zeppelin seaplane. It was Blackburn's first multi-engine aircraft to fly.
The Nieuport 12 was a French sesquiplane reconnaissance, fighter aircraft and trainer used by France, Russia, Great Britain and the United States during World War I. Later production examples were built as trainers and served widely until the late 1920s.
The Pemberton-Billing P.B.25 was a First World War British single-seat scout aircraft built by Pemberton-Billing Limited, later Supermarine Aviation Works Limited.
The Bentley BR.1 was a British rotary aircraft engine of the First World War. Designed by the motor car engine designer W. O. Bentley, BR.1s powered the majority of Sopwith Camels flown by the Royal Naval Air Service (RNAS).
The Clerget 9B is a nine-cylinder rotary aircraft engine of the World War I era designed by Pierre Clerget. Manufactured in both France and Great Britain, it was used on such aircraft as the Sopwith Camel. The Clerget 9Bf was an increased stroke version.
The Franco-British Aviation Model 290 was a French four-seat amphibian flying boat built by the Franco-British Aviation Company (FBA) as a replacement for the Model 17 in French naval service.
The Donnet-Denhaut flying boat was a maritime patrol and anti-submarine warfare aircraft produced in France during the First World War. Known at the time simply as "Donnet-Denhaut" or "DD" flying boats, the DD-2, DD-8, DD-9, and DD-10 designations were applied retrospectively to denote the various changes in configuration made during their service life.
The FBA Type H was a French reconnaissance flying boat produced in large numbers in France and Italy during World War I by Franco-British Aviation.
The Sopwith Admiralty Type 807 was a 1910s British biplane seaplane designed and built for the Admiralty by the Sopwith Aviation Company.
The Sopwith Two-Seat Scout was a 1910s British biplane Anti-Zeppelin scout biplane designed and built for the Admiralty by the Sopwith Aviation Company. It was nicknamed the Spinning Jenny due to a tendency to enter a spin.
The Blériot 67 was a First World War French heavy bomber designed and built by Blériot for a 1916 competition Concours des Avions Puissants. Only a single prototype was built.
The Caudron G.2 was a single-engined French biplane built by Caudron, used in World War I as a reconnaissance aircraft and trainer.
The Courtois-Suffit Lescop CSL C1 was a prototype French biplane fighter built in the final months of World War I. It was one of the first aircraft, if not the first, to be fitted with leading-edge flaps. It was not put into production.
The Nieuport 17bis C.1 was a World War I French single-seat sesquiplane fighter that was produced under licence in the United Kingdom in small numbers for the Royal Naval Air Service.
