The Zeppelin-Staaken Type 8301 refers to a series of four sizeable seaplanes, identified by serial numbers 8301 through 8304,[lower-alpha 1] developed for use by the Imperial German Navy in World War I. These aircraft represent the largest floatplanes ever produced, though not the heaviest.[2][3]
Design
Drawing on insights gained from trials with the Zeppelin-Staaken Type L, the Kaiserliche Marine commissioned these planes in two stages: initially ordering units 8301 and 8302 in December 1917, followed by an additional four, numbered 8303 to 8306, in January 1918.[4]
The design incorporated wings from the Zeppelin-Staaken R.VI, combined with a newly engineered fuselage positioned centrally between the main wings.[5] Elevating the fuselage in this manner aimed to enhance the craft’s performance on water.[4][6] The nose featured expansive cellon glazing that encircled it entirely, delivering superior visibility.[4][6] Defensive armament mirrored that of Zeppelin-Staaken bombers, supplemented by accommodation for two 20-millimetre (0.79 in) cannons mounted in the rear fuselage for engaging naval targets.[1][6] The bomb payload consisted of ten 10-kilogram (22 lb) bombs housed in canisters adjacent to the nose section.[1] Fuel capacity was provided by twelve 300-litre (66 imp gal; 79 US gal) tanks, enabling flight endurance between nine and ten hours.[1]
Tailplane design was derived from the R.XIV and R.XV models,[5] while floats were similar to those utilized on the Type L.[5]
Development
The aircraft designated 8301 took to the skies for the first time in mid-1918, initially undergoing trials with a conventional land undercarriage before being equipped with duralumin floats. Testing of both 8301 and 8302 was in progress at Warnemünde during the conclusion of the war, prior to their official acceptance into naval service.
Within the second production series, only units 8203 and 8204 had been completed but remained undelivered. The Military Inter-Allied Commission of Control later located these aircraft stored in Zeppelin-Staaken's seaplane hangar at Wildpark near Potsdam.
Operational history
Though these aircraft never entered active wartime duty, 8301—and potentially 8303 and 8304—were briefly repurposed as civilian airliners following the war, operating weekend passenger flights between Berlin and Swinemünde.
