The Caproni Ca.90 was a prototype Italian heavy bomber designed and built by Caproni. When it first flew in 1929 it was the largest aircraft in the world.[1]

Design and development[edit]

A six-engined inverted sesquiplane, the Caproni Ca.90 was designed as a heavy bomber and first flew in 1929.[1] It had two tandem pairs of 1,000 hp (746 kW) Isotta-Fraschini Asso 1000 W-18 inline piston engines mounted above the lower wing, each pair driving a four-bladed pusher and a two-bladed tractor propeller.[1] Another pair of engines was mounted above the fuselage.[1] Only one Ca.90 was built.[1]

Although the Dornier Do X flying boat that flew later in 1929 had a larger wingspan and weight, the Caproni Ca.90 remained the largest landplane until the arrival of the Tupolev ANT-20 in 1934.[1]
