Internal keel walking way.
Balanced monoplane rudders and elevators.
Five cars. Two forward (combined as in Stage 3),
one aft, and two amidships abreast.
Six engines and six propellers. The after one of the
forecar and the sidecars each contain one engine
driving direct a pusher propeller. The after car
contains three engines, two of which drive two wing
propellers; the third, placed aft, drives direct a
pusher propeller.
In this stage the type of girders was greatly altered.

A company known as the Schutte-Lanz Company was also responsible
for the production of rigid airships. They introduced a design,
which was a distinct departure from Zeppelin or anyone else. The
hull framework was composed of wood, the girders being built up
of wooden sections. The shape of these ships was much more of a
true streamline than had been the Zeppelin practice, and it was
on this model that the shape of the super-Zeppelin was based.
These ships proved of use and took part in raids on this country,
but the Company was taken over by the Government and the
personnel was amalgamated with that engaged on Zeppelin
construction during the war.

were considered for a commencement, the P type or Piccolo was the
