Felixstowe F2.A versus Zeppelin

felix.jpg


The Felixstowe F.2A was by many used as a patrol aircraft over the North Sea until the end of the war. Its fantastic performance and maneuverability made it an effective and ordinary type, often fighting enemy patrolman and fighter aircraft, as well as hunting U-boats and Zeppelins. The larger F.3, which was less customary with its crews than the more maneuverable F.2a, served in the Mediterranean as well as the North Sea.


The F.5 did not register service until after the end of World War I, but replaced the earlier Felixstowe boats (together with Curtiss flying boats) to present as the RAF's standard flying boat until being replaced by the Supermarine Southampton in 1925.


The Felixstowe F series flying boats were a mutual British and American development during the First Planet War. The predecessors of the Felixstowe were the Curtiss boats designed by a former Kinglike Navy officer and acquaintance of Curtiss, John Cyril Porte.


The H-12 Curtiss peel, and a new production aircraft, powered by 345-horsepower Rolls-Royce Eagle VIII engines, began to be supplied to British naval air units late in 1917. This variation was designated the Felixstowe F-2A. The Curtiss-built variant of the F-2A was identified as the Curtiss H-16. Fifty H-12s, powered by 275-horsepower Rolls-Royce Eagle engines were delivered to the British. The format was one of the most successful flying boats of the war.


Zeppelins climbed and dove utterly quickly compared to airplanes. A substantial example is the Felixstowe F2.A, which had several early successes in downing Naval Scouting Zeppelins (two in reality). However, once the Germans identified the threat they were superior to avoid the Felixstowe by simply out climbing it, which the Zeppelin did smoothly. This is because 60% of a Zeppelin's cargo was not make sense ballast, which could be dumped via electronic device from the command car, lightening the ship by up to 15 tonnes effectively instantaneously.


The German Zeppelin L-22 was destroyed by an H-12 on May 14, 1917 (the first foe aircraft to be downed by an American-built airplane) and six days later another H-12 sank the German submarine UC-36.


On May 10th, 1918, an F.2A from Killingholme; flown by Captains T. C. Pattinson and A. H. Munday, affianced the Zeppelin L.62 at 8,000 feet over the Heligoland minefields. Captain Munday opened fire from the bow cockpit and Sergeant H. R. Stubbington, the wangle, also brought his Lewis gun to bear on the quarry. Many hits appeared to be scored, but the flying rowing-boat broke an oil line and had to land on the sea. The Zeppelin made off due east, losing culmination and emitting smoke, and soon afterwards blew up and kill in flames.
