In 1933
Marshal Italo Balbo, Minister of the Italian Air Force, contacted Blériot to ask if Dr. Filippo Zappata could be released from the French contract so that he could work in Italy again. Blériot agreed, with the understanding that Zappata acted as a consultant for the final work on the postal seaplane
Santos Dumont. This aircraft was a complete success beating world distance records and Zappata was awarded the
Légion d'Honneur by the French Government. He was now back at CANT in Monfalcone and developed such a large number of highly successful projects that the firm expanded in a few years from 340 workers to 5,500 workers.
Seaplanes At CANT, Zappata designed a series of successful multi-engined
seaplanes such as the
CANT Z.501 Gabbiano flying boat and the
CANT Z.506 Airone floatplane. Zappata's predilection for all-wooden airframes was strongly in evidence in both Gabbiano and Airone. Despite this, both planes were robust and stood up well to harsh conditions. In association with test pilot
Mario Stoppani, chief pilot for CANT, Zappata's designs set 41 world aeronautical records. CANT Z.506 still holds the distance record for a seaplane in a closed circuit.
Medium bombers In the mid-1930s Zappata designed a series of
medium bombers, including the three-engined
CANT Z.1007 and twin-engined
CANT Z.1011. Along with the
Savoia-Marchetti SM.79, the CANT Z.1007 formed the backbone of the Regia Aeronautica's wartime medium bomber force. Production began in 1939 and by June 1940, 87 units were combat-ready in the Z-1007 and Z-1007bis versions outfitting the 16th and 47th bomber wings. Its worst drawback was the scarcity of its defensive armament, but in all other respects, it proved to be an excellent bomber, operating in the
Mediterranean (as a
torpedo bomber as well), in
North Africa and, briefly, in
Russia. The last design by Filippo Zappata before he left CANT for Breda was the
Z.1018 Leone twin-engined medium bomber, considered the best bomber built in Italy during World War II.
Breda Around 1939 Zappata became disillusioned with CANT. At the beginning of 1942, the
Società Italiana Ernesto Breda, idle after the failure of its
Ba.88, offered him the post of chief aeronautical engineer. Aware of the importance of this firm, Zappata accepted. At Breda, Zappata proposed several variants of the CANT Z.1018 Leone: • BZ.301 (Breda-Zappata, mod.301), high altitude bomber; • BZ.302, high altitude fighter; • BZ.303,
night fighter,
torpedo bomber multirole; • BZ.304, anti-tank (perhaps with a 37 mm gun). The Italian Air Ministry authorized only the BZ.301 and 303, called
Leone II and
Leone III. The signing of the
Armistice of Cassibile in September 1943, the subsequent
occupation of the Italian peninsula by the Wehrmacht, and the almost total destruction of the Breda aircraft factory on 30 April 1944 by
U.S. bombers, ensured that none of the new projects launched by Zappata during the latter stages of World War II were realized. The sole prototype of BZ.303 under construction in 1943 was destroyed by the Germans soon after the armistice. == Career after the War ==
