The Port Victoria P.V.9 was a British single-seat biplane floatplane fighter of the First World War. Although claimed to be the best aircraft of its type yet to be tested, only a single prototype was built.

Design and development

In mid-1917, the RNAS Marine Experimental Aircraft Depot at Port Victoria on the Isle of Grain was instructed to build a new single-seat floatplane fighter as a possible replacement for the Royal Naval Air Service (RNAS)'s Sopwith Babies. The new aircraft was to combine the good manoeuvrability and pilot view of Port Victoria's earlier P.V.2 floatplane with superior speed. [1] [2]

Like the P.V.2, the new design, the Port Victoria P.V.9 was a single-engined sesquiplane (i.e. a biplane with its lower wing much smaller than its upper wing) braced with faired steel tubes. The fuselage, wider than that of the P.V.2, was mounted between the upper and lower wings, almost filling the inter-wing gap, giving an excellent view for the pilot. Armament was a Vickers machine gun synchronised to fire through the propeller disc, with a Lewis gun mounted above the upper wing firing over the propeller. Power was provided by a Bentley BR1 rotary engine. While the designers had hoped to use the same high-lift aerofoil section as used in the P.V.2, this was rejected by the Admiralty, who demanded the use of the more conventional RAF 15 aerofoil, which resulted in a larger aircraft with a reduced climb rate and ceiling. [2] [3]

Operational history

The P.V.9 made its maiden flight in December 1917, but trials were delayed by engine troubles and by a collision of the aircraft with a barge, which resulted in a propeller not matched properly to the aircraft being fitted, further reducing performance. Despite this, when the P.V.9 was officially tested in May 1918, the P.V.9 was said to be the best seaplane fighter tested up to that time. [3] [4] No production followed, however, as the availability of Sopwith Pup and Camel landplanes which could operate from platforms aboard ships, removed the requirement for a floatplane fighter.

Sopwith Salamander British WW1 biplane ground attack/close support aircraft

The Sopwith TF.2 Salamander was a British ground-attack aircraft of the First World War designed by the Sopwith Aviation Company which first flew in April 1918. It was a single-engined, single-seat biplane, based on the Sopwith Snipe fighter, with an armoured forward fuselage to protect the pilot and fuel system from ground fire during low level operations. It was ordered in large numbers for the Royal Air Force but the war ended before the type could enter squadron service, although two were in France in October 1918.

Sopwith Snipe British WW1 biplane fighter aircraft

The Sopwith 7F.1 Snipe was a British single-seat biplane fighter of the Royal Air Force (RAF). It was designed and built by the Sopwith Aviation Company during the First World War, and came into squadron service a few weeks before the end of the conflict, in late 1918.

Sopwith Tabloid

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 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 Port Victoria P.V.7 Grain Kitten was a prototype British Fighter aircraft of the First World War designed and built by the Port Victoria Marine Experimental Aircraft Depot on the Isle of Grain. A very small and light biplane intended to fly off platforms on Royal Navy Destroyers, it was unsuccessful, only a single prototype being built.

The Port Victoria P.V.1 was a British prototype floatplane fighter of the First World War, built at the Royal Naval Air Service's Port Victoria Marine Experimental Aircraft Depot on the Isle of Grain by fitting a Sopwith Baby with high-lift wings. Only a single aircraft was built, with the type not being chosen for production.

The Grain Griffin was a British carrier-based reconnaissance aircraft developed and built by the RNAS Marine Experimental Depot, Port Victoria, during the First World War. A development of the unsuccessful Sopwith B.1 bomber, the Grain Griffin was a two-seat single-engined biplane that was built in small numbers for Britain's Royal Naval Air Service, being used operationally during the British intervention in the Russian Civil War.

The Nieuport B.N.1 was a prototype British single-engined fighter aircraft of the First World War. It was a single-engined biplane intended to replace the Sopwith Camel, but only one was built, being destroyed in a crash. The Sopwith Snipe was built instead to replace the Camel.

The Westland N.1B was a prototype British single-engined floatplane fighter aircraft of the First World War. The first aircraft to be designed by Westland Aircraft, it was a single-engined tractor biplane. Despite good performance, only two aircraft were built, the Royal Naval Air Service operating landplane fighters from ships instead.

The Sopwith Snapper was a prototype British fighter aircraft of the First World War. A single-engined biplane designed by the Sopwith Aviation Company to replace the Sopwith Snipe fighter, it first flew after the end of the war, but did not enter service owing to the failure of its engine, only three aircraft being built.

The Sopwith 2FR.2 Bulldog was a prototype British two-seat fighter of the First World War. A single-engined biplane, the Bulldog was a fighter/reconnaissance aircraft intended to replace the Bristol F.2 Fighter, but was unsuccessful, with no replacement for the Bristol Fighter being purchased.

The Sage Type 2 was a prototype British two-seat fighter aircraft of the First World War. A single-engined biplane with an enclosed cabin for its crew, only a single example was built, as more advanced aircraft became available.

Norman Thompson N.1B

The Norman Thompson N.1B was a prototype British flying boat fighter aircraft of the First World War. A two-seat single-engined pusher biplane, a single example was built in 1917, but no production followed.

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 Sopwith 3F.2 Hippo was a prototype British two-seat fighter aircraft of the First World War. It was a single-engined biplane with considerable negative stagger. It was not successful, the Bristol F.2 Fighter being preferred by the Royal Flying Corps.

The Port Victoria P.V.4 was a prototype two-seat reconnaissance floatplane of the First World War. The P.V.4 was a small single engined pusher biplane. It was unsuccessful as the engine it was designed around was a failure and alternatives were unsuitable, only one aircraft being built.

The Port Victoria P.V.5 was a British single-engined floatplane fighter aircraft of the First World War. A single example was built and flown at the Royal Naval Air Service's Port Victoria Marine Experimental Aircraft Depot on the Isle of Grain in 1917. Despite demonstrating good manoeuvrability and handling, no production followed, with the Royal Naval Air Service instead using landplanes for the fighter role.
