In this later design, namely, the 23 X class, it was considered
that the weights could be concentrated and suspended from the
radial wiring of the transverse frames and that the keel,
incorporated in the design of the former ships, could be
dispensed with.

For all practical purposes, apart from the absence of the keel,
the 23 X class of airship may be regarded as a slightly varied
model of the 23 class. The main dimensions are nearly the same,
and the general arrangement of the ship is but little changed.
The loss of space owing to the introduction of the internal
corridor is compensated by a modification of the shape of the
bow, which was redesigned with a deeper curve. The hull
structure was also strengthened by utilizing a stronger type of
girder wherever the greatest weights occur. In these
strengthened transverse frames the girders, while still remaining
of the triangular section, familiar in the other ships, are
placed the opposite way round, that is, with the apex pointing
outwards.

The walking way is situated at the base of the hull passing
through the gas chambers, which are specially shaped for the
purpose. The corridor is formed of a light construction of
hollow wooden struts and duralumin arches covered with netting.

In all other leading features the design of the 23 class is
adhered to; the gasbags are the same, except for the alteration
due to the internal corridor, and the system of valves and the
various controls are all highly similar.
