The Ca 311 differed from its predecessor in having the “stepped” windscreen replaced by a more extensively glazed Blenheim I-style dose section (although the second production series, the Ca 311M (Modificato) reverted to a stepped canopy rather like that later adopted for the Ca 314), and the Ca 312 was a version with 630-h.p. Piaggio P.XVI R.C.35 radials.
Defensive armament was a Caproni Lanciani turret with a single 7.7mm machine-gun, and one machine-gun in the port wing root and another firing aft through a ventral hatch.
The Ca 312M possessed a similar nose to that of the Ca 311, the Ca 312bis was a twin-float seaplane variant, and the Ca 312-1S was an experimental torpedo floatplane. The Ca 313 was a further development of the Ca 311 with two 650-h.p. Isotta-Fraschini Delta R.C.35 engines which was used in limited numbers on the Russian Front.
(SABCA) made a marketing agreement with the Italian company Caproni, with SABCA selling some of Caproni’s military aircraft in certain markets, including the Caproni Ca.135, Ca.310 and the Ca.312, which were to be designated SABCA S.45bis, S.46 and S.48 respectively.
