The Caproni Ca.310 Libeccio (southwest wind) was an Italian monoplane,
twin-engine reconnaissance aircraft used in World War II. Derived from the
similar Ca.309, it had its combat debut during the Spanish Civil War and took
part in the earlier phases of World War II in Libya. Some were used in attack
groups as a temporary replacement for the unsatisfactory Breda Ba.65. The last
Ca.310 was retired by the Italian Air Force in 1948.
The Ca.310 was designed as a low-wing monoplane reconnaissance/bomber, being
essentially a version of the semi-military Ca.309 with retractable landing gear
and uprated engines. The fuselage was of welded steel tube construction with a
covering of light alloy panels and fabric, while the empennage/tail unit was of
wooden construction with plywood skin on its fixed portions and fabric covering
on control surfaces.
Above the fuselage, mounted in line with the wing trailing edges was a
manually operated dorsal turret armed with a single rifle-caliber (7.7 mm/0.303
in) Breda-SAFAT machine gun.
Caproni pinned great hopes on the Ca. 310's effectiveness as a combat
aircraft, only to be dashed when its performance fell short of expectations.
This lack of performance resulted in both Norway and Hungary being disappointed
with the export models they received in 1938. The Ca.310 had been evaluated by
the Regia Aeronautica (Italian Air Force) which ordered a small batch. A unit
of 16 aircraft was sent to Spain in July 1938 for operational trials as a
reconnaissance/bomber by the Italian expeditionary force operating alongside
the Nationalist insurgents in the Spanish Civil War.
The Norwegian aircraft were acquired as part of a dried and salted cod
(Klippfisk) barter deal between Norway and Italy. The original order, including
options, was for 24 aircraft, but after seeing that the aircraft did not
perform well, the Norwegian authorities refused to accept any further Ca.310s.
Instead, a delivery of 12 Caproni Ca.312s with upgraded engines and improved
performance was substituted, but not delivered before the German invasion of
Norway on 9 April 1940. A similar scenario occurred with other export
contracts, especially with a hoped-for Royal Air Force order for bomber
trainers being curtailed during negotiations with Caproni when Italy entered
the war as an Axis power.
A series of 12 Ca.310bis were produced for Yugoslavia. This variant
differed mainly in having an unstepped, glazed nose. The prototype Ca.310bis
served as the development for the Caproni-Begamaschi Ca.311.
The 33 Hungarian Ca.310s returned to Italy were refurbished by Caproni
and reissued to the 50˚ Stormo d’Assalto. The Ca.310 was not considered an
effective combat aircraft and when it saw service during World War II, it was
as a reconnaissance aircraft and as a light bomber in areas where no serious
opposition was expected.
Peruvian Aeronautical Corps Ca.310s took part in the July 1941
Ecuadorian-Peruvian war. Together with North American NA.50s, the Peruvian
Ca.310s flew bombing missions against Ecuadorian cities and supported Army of
Peru ground forces. One Norwegian example has been partially restored and is
displayed at Sola Aviation Museum.

It departed Croydon, near London, on 17 April 1938, and crashed on the Lybian Coast on the 18th, and was subsequently destroyed. |

The aircraft, military codes 501, 503, 505, 507, were deployed on Lillestrom airfield. At the time of the German invasion in April 1940, the Ca.310s were at Sola, but their involvement in war operations was very limited, only one or two sorties. |
