Porte F.2A America
Best known was the F.2A, which, in the last year of the war, formed the backbone of RNAS/RAF ocean activity. Carrying up to seven Lewis guns and two 220 lb bombs, it had a maximum weight of 11,000 lb, its two 345 hp Rolls-Royce Eagles gave it a top speed of 95 mph and it could reach 2,000ft in 3.5min and 10,000ft in 39.5min. Despite its 120ft wingspan it was surprisingly agile. Gradually F.2s replaced H12s.
The F2A was basically a Porte II hull married to the wings and tail unit of the Curtiss H.12. Utilised by Britain during WW 1 and credited with shooting down Zeppelins L.22, L.43 and L.62.
