Designed by
Ingeniere Rodolfo Verduxio, the Caproni Ca 133 was an
aerodynamically and structurally improved Ca 1O1 which first
appeared in 1927. Of welded steel-tube construction with metal
and fabric covering, the Ca 133 featured faired engine
nacelles with NACA cowlings, main wheel spats, flaps and
modified tail surfaces. The civil version accommodating up to
16 passengers, was used by Ala Littoria, and the military
version saw wide service with the Regia Aeronautica,
particularly in Italian East Africa. Incorporating two small
bomb bays in its structure and armed with four 7.7 mm (0.303
in) Breda-SAFAT machine-guns it was operated as a bomber under
the designation Ca 133. Bomber aircraft deployed as military
transports, with an interior fitted out to accommodate 18
fully equipped troops, were redesignated Ca i33T and,
similarly, conversions for use in an ambulance role were
designated Ca 133S.
In 1938 a small number of an improved
version of the Ca 133 was introduced under the designation Ca
148, serving initially in East Africa, and some survived to
fly with the post-war Italian air force. The Ca 148 differed
from the earlier aircraft by having the cockpit moved forward
by approximately 3 ft (0.91 m), the main cabin door relocated
from its original position below the port wing to a point
behind the trailing edge, and strengthened landing gear. Exact
figures are not known, but its thought around 419 Ca 133s were
built with an other 106 Ca 148s being produced as well.
