[2][page needed] The first Zeppelin-Staaken R-planes were made by Ferdinand von Zeppelin, aided by Robert Bosch GmbH (engineers), the V.G.O.
"-series of Zeppelin-Staaken "Giants" were very large aircraft by the standards of 1915, and its four-bay interplane-strut per side wing structure, planform shape (having slightly swept-back leading edges) and general wing structural dimensions would be used, almost unchanged, for the entire series of Zeppelin-Staaken multi-engined giant aircraft through to 1917-18.
[1][page needed] Engine installation variations included: Construction of the aircraft was almost entirely of wood or plywood with fabric covering, steel detail fittings and struts.
The wings were three bay strutted and wire-braced assemblies supporting the engine nacelles, at around mid gap and the single axle main undercarriage units.
