Felixstowe F.5
The Felixstowe F.5 was a British First World War flying boat designed by Lieutenant Commander John Cyril Porte, RN of the Seaplane Experimental Station in Felixstowe.
Design and development
Porte designed a better hull for the larger Curtiss H-12 flying boat, resulting in the Felixstowe F.2A, which was greatly superior to the original Curtiss boat. This entered production and service as a patrol aircraft. In February 1917, the first prototype of the Felixstowe F.3 was flown. This was larger and heavier than the F.2, giving it greater range and a heavier bomb load but inferior manoeuvrability. The Felixstowe F.5 was intended to combine the good qualities of the F.2 and F.3, with the prototype first flying in November 1917. The prototype showed superior qualities to its predecessors, but the production version was modified to make extensive use of components from the F.3 in order to ease production, giving a lower performance than either the F.2A or F.3.Operational history
The F.5 did not enter service until after the end of the First World War but replaced the earlier Felixstowe boats to serve as the Royal Air Force's standard flying boat until being replaced by the Supermarine Southampton in 1925.Variants
