The interior of the aircraft was divided into several sections, one of which formed a dedicated compartment for the navigator.

Each of these nacelles contains a pair of box girders that were extensions of the wing structure. A combination of box girders and oblique tubular struts supported the

relatively high speed of the aircraft for the era posed some challenges to the effective firing of defensive guns, although Blériot made attempts to compensate for the sighting difficulties. To this end, the forward gunner's position was protected by the circular
