Developed from Caproni Ca.335

The Caproni Ca.355 Tuffo was a low-wing single-engine dive bomber, designed and built by the Italian Caproni company in 1941, which never proceeded beyond a single prototype. Derived from Ca.335 Mistral, the Ca.355 was proposed to equip the Regia Aeronautica, but it was found to offer little advantage over the German Junkers Ju 87 "Stuka" and the project was abandoned.

Development

In 1939 the Ministry of Aeronautics issued a specification for the supply of an aircraft of the same class as the Junkers Ju 87 to be allocated to the bomber divisions of the Regia Aeronautica. [1]

Caproni chose to participate with a project entrusted to engineer Cesare Pallavicino and developed by his subsidiary, Cantieri Aeronautici Bergamaschi (CAB). Pallavicino exploited the experience gained in the development of the previous Ca.335 Maestrale, proposing a simplified development with slightly smaller dimensions and with minor modifications to make it suitable for the new role. [2]

The fuselage was reduced in diameter and the second cockpit was eliminated as being unnecessary, leaving only a single enclosed cockpit with a rearward sliding canopy. Air brakes were added to the wing and, as with the Stuka, a tubular trapeze was included to hold the bomb and ensure it cleared the propeller when dropped during a vertical dive. The Isotta Fraschini Delta engine developed by another company in the Caproni group was chosen to power it. [2]

The prototype, serial MM.470 and now designated Ca.355 Tuffo, was flown by test pilot Ettore Wengi on 14 January 1941 from the company airfield at Ponte San Pietro. After initial trials in which no major problems were found, it was delivered to the Regia Aeronautica. [2] While satisfying the original requirements, the military were not satisfied with its performance and it only carried out a few test flights. The Regia Aeronautica chose to continue operating the Junkers Ju 87 "Stuka", in addition to converting obsolete fighters such as the Fiat CR.42, Fiat G.50 Freccia and the Macchi MC.200 to the dive bombing role. [2] The fate of the sole Ca.355 built is unknown.
