Oeffag G

The Oeffag G , sometimes known as the Oeffag Type G or Oeffag-Mickl G, was a three-engined reconnaissance flying boat built in Austria during the First World War and deployed by the Kaiserlich und Königlich Seefliegerkorps ("K.u.K. Seefliegerkorps") (Imperial and Royal naval aviation).
Design and development.
The Oeffag G was a relatively large flying boat, following the design practises used for the smaller Lohner flying boats developed in Austria contemporaneously. The aircraft was a biplane with the wings mounted above a slender all-wood monocoque fuselage/hull, with the biplane tail unit mounted above the extreme tail end of the fuselage. The three pusher engines were mounted in open nacelles, supported by struts, between the main-planes. Early aircraft were armed with a large D/20 cannon in the front cockpit and later machines had a machine gun fitted on a flexible mount aft of the wings.
Operational history.
Most of the ten aircraft completed saw service with the "K.u.K. Seefliegerkorps", from 1916, operating principally from the Pola Naval station, (now Pula), on the Istria peninsula, in what is now Croatia.
Variants.
The Oeffag G was developed as each aircraft was built, but the major differences involved the powerplants and the tail unit.
