Caproni Ca.313 / Ca.314
A modified Ca.310 with two Isotta-Fraschini Asso 120 IRCC 40 engines served as the Ca.313 prototype, first flown on 22 December 1939, but France had already confirmed an order for 200 Ca313 RPB1 on 1 October, followed closely by British and Swedish orders for 300 and 64 respectively.
The Caproni Ca313 and Ca314 were comparatively small and light aircraft powered by two Isotta-Fraschini Delta RC35 twelve-cylinder in-line engines of 700hp each. Both aircraft were constructed of a mixture of wood, metal and fabric and were developed versions of the Ca311 and 312M for multi-role use.
The Ca313 and Ca314 fulfilled a specification for a lightweight general-purpose combat aircraft capable of being used for reconnaissance, light bombing, ground attack, training and torpedo-attack. Both types had similar speed performance, in the 250-270mph category.
The torpedo installation was carried by the Ca313 RPB 1 SIL and Ca314 SIL (silurante =torpedo, in Italian).
These aircraft were also used by the Luftwaffe and some were used after capture by the Allies as communications aircraft in North Africa.
Italy's entry into the war prevented delivery of any of the British machines and France received only five Ca.313F models, the remainder being diverted to the Regia Aeronautica.
Eighty Ca 313 were exported to Sweden in 1940. According to Swedish sources, the Ca 313 was generally unsatisfactory and had to be rebuilt and extensively strengthened after delivery. Forty-one Swedish airmen lost their lives in accidents involving the Ca 313 and, after the war. The Swedish Government took legal action against the Caproni concern but, in the meantime, the Societa Italiana Caproni had gone into liquidation.
Most extensively built version was the Ca.314.
The Ca 314, an improved version of the Ca 313, was the last of the Bergamaschi-designed light twin-engined reconnaissance bombers to be produced in quantity. It was also used in small numbers by the Luftwaffe and was to have been built under license in Germany as the Ca 315 (featuring a modified nose similar to that of the Ca 316).
Variants included the Ca.314A or Ca.314-SC (Scorta), a convoy escort/maritime patrol aircraft, the Ca.314B or Ca314-RA (Ricognizione Aerosiluranti) torpedo-bomber and the ground-attack Ca.314C. The extra under-fuselage gun packs were carried by the Ca314C. These additional items were not normally carried by the reconnaissance-bomber versions.
