Italian Engineer Celesiino Rosatelli's first fighter prototype, designated CR. was designed during the early 1920s. The CR was ordered into production in 1924 under the new designation CR 1 (Caccia Rosatelli — Fighter/Hunter Rosatelli). This single design began an unbroken string of Italian FIAT (Fabbrica Italiana Automobili Torino) biplane fighters that lasted to the end of World War II in 1945. Three different firms produced almost 250 CR I fighters between 1924 and 1926.
The CR 5. a further development of the CRI, was developed in 1925. Two prototypes, one powered by a British-designed nine cylinder Jupiter radial engine, and the other employing a 12 cylinder FIAT A.20 inline engine were completed, but by then, the level of aircraft and engine development had outpaced the original CR 1 design. Both the CR I and CR 5 fighters were unusual in employing a reverse sesquiplane wing design — the lower wing having a greater area than the upper wing. Development of the CR 5 was halted in favor of a more promising design — the FIAT CR 20.
