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 P.B.23 was designed in 1915 as a single-seat biplane scout, with a fuselage nacelle strut-mounted between the wings. The nacelle had an open cockpit for the pilot at the front and at the rear an 80 hp (60 kW) Le Rhône 9C engine driving a pusher propeller. Twin fins and rudders were mounted on a wide-span tailplane with an elevator attached, all connected to the wing structure with four tailbooms. The P.B.23 failed to gain an order after it first flew in September 1915, but twenty of an improved version, the P.B.25, were ordered by the Royal Naval Air Service. The P.B.25 had swept-back wings, a modified landing gear and a revised fuselage nacelle and although originally powered by a 110 hp (82 kW) Clerget rotary engine, the 20 RNAS aircraft were fitted with Gnome Monosoupape 9 Type B-2 rotary piston engines.
The aircraft, which were not used operationally, were based at RNAS Hornchurch and RNAS Hendon, where they were probably used in the training role.

The Sopwith Pup was a British single-seater biplane fighter aircraft built by the Sopwith Aviation Company. It entered service with the Royal Naval Air Service and the Royal Flying Corps in the autumn of 1916. With pleasant flying characteristics and good manoeuvrability, the aircraft proved very successful. The Pup was eventually outclassed by newer German fighters, but it was not completely replaced on the Western Front until the end of 1917. Remaining Pups were relegated to Home Defence and training units. The Pup's docile flying characteristics also made it ideal for use in aircraft carrier deck landing and takeoff experiments and training.
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.
The Vickers F.B.5 was a British two-seat pusher military biplane of the First World War. Armed with a single .303 in (7.7 mm) Lewis gun operated by the observer in the front of the nacelle, it was the first aircraft purpose-built for air-to-air combat to see service, making it the world's first operational fighter aircraft.
The Bristol Scout was a single-seat rotary-engined biplane originally designed as a racing aircraft. Like similar fast, light aircraft of the period it was used by the RNAS and the RFC as a "scout", or fast reconnaissance type. It was one of the first single-seaters to be used as a fighter aircraft, although it was not possible to fit it with an effective forward-firing armament until the first British-designed gun synchronizers became available later in 1916, by which time the Scout was obsolescent. Single-seat fighters continued to be called "scouts" in British usage into the early 1920s.
The Blackburn TB was a long-range twin-engined anti-Zeppelin seaplane. It was Blackburn's first multi-engine aircraft to fly.
The Royal Aircraft Factory F.E.8 was a British single-seat fighter of the First World War designed at the Royal Aircraft Factory. It could not escape the drag penalty imposed by its tail structure and was no match for the Albatros fighters of late 1916.
The Wight Baby was a British single-seat seaplane fighter produced by John Samuel White & Company Limited. Only three prototype aircraft were built.
The Bristol T.B.8, or Bristol-Coanda T.B.8 was an early British biplane built by the Bristol Aeroplane Company and designed by the Romanian Henri Coandă. Fifty four Bristol T.B.8s were built, being mainly used as a trainer. A small number of Bristol T.B.8s were briefly used as bombers at the start of the World War I by the Royal Naval Air Service.
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 made of ash longerons covered in laminated wood, 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.
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 Vickers F.B.12 was a biplane pusher fighter aircraft developed during World War I by Vickers Limited. The failure of the engine for which it was designed, and the obsolescence of the pusher configuration, resulted in its remaining an experimental type only.
The Port Victoria P.V.2 was a British prototype floatplane fighter of the First World War, designed and built at the Royal Naval Air Service's Port Victoria Marine Experimental Aircraft Depot on the Isle of Grain. Only a single aircraft was built, with the type not being chosen for production.
The Blackburn Triplane was a single-engine pusher single-seater, designed specifically to attack Zeppelins. It flew in 1917, but was not successful.
The Sopwith Gunbus was a British fighter aircraft of the First World War. It was a single-engined pusher biplane based on a floatplane built by Sopwith before the war for Greece. Small numbers were built and used by the British Royal Naval Air Service, mainly as a trainer.
The Short S.80 was an early British floatplane built by Short Brothers for Frank McClean to undertake an aerial expedition up the Nile to investigate the cataracts between Aswan and Khartoum. After a successful flight to Khartoum it was returned to England, where it was used for training by the RNAS. When built it was the largest successful aircraft that had been constructed in Britain. It was also known as the Short Nile Pusher Biplane Seaplane.
The Pemberton-Billing P.B.1, sometimes known as the Supermarine, was a 1910s British single-seat flying-boat built by Pemberton-Billing Limited, which later became the Supermarine Aviation Works. Only one P.B.1 was built, and it never flew any distance further than a hop.
