H.King Armament of British Aircraft (Putnam)
P.V.5 and P.V.5a. The P.V.5 of 1917 was a fighter bomber, carrying two 65-lb bombs internally. The pilot had a Vickers gun mounted on top of the fuselage.

PORT VICTORIA P.V.5 UK
Shortly after the Depot initiated work on the P.V.4, it was asked to develop a single-seat fighter seaplane also capable of performing light bombing tasks with two internally-stowed 65-lb (29,5-kg) bombs. To meet this requirement, two different aircraft were designed and built, the P.V.5 and the P.V.5a. The former was developed from the P.V.2bis and employed a similar sesquiplane wing cellule devoid of flying wires and braced by struts to the float undercarriage. The wings employed a high-lift aerofoil section, the armament comprised a single synchronised 0.303-in (7,7-mm) machine gun plus the two 65-lb (29,5-kg) bombs specified and power was provided by a 150 hp Hispano-Suiza engine. Fitted with pontoon-type floats rather than the Linton Hope floats for which it had been designed, the P.V.5 was flight tested in mid-1917 with promising results, but the original requirement had been overtaken and development was discontinued.

PORT VICTORIA P.V.5a UK
Designed along more conventional lines than the P.V.5, the P.V.5a was an equi-span single-bay biplane with cable bracing, sharing with the former type only the fuselage, tail surfaces and armament. The pontoon-type floats were supplanted by Linton Hope floats, the internal accommodation for a bomb load was eliminated and a 200 hp Hispano-Suiza engine was fitted. Work on the P.V.5 and 5a was initiated in parallel, but work on the latter was discontinued early in 1917, and only reinstated after the P.V.5 had flown, the P.V.5a commencing flight test in the spring of 1918. It proved inferior to the P.V.5 in terms of manoeuvrability and pilot’s view, but was satisfactory in most other respects. Development was discontinued after completion of flight testing as no service requirement for this category of aircraft existed.
