The final production series of the large Caproni Ca.4 series was the Caproni Ca.42 of 1918. The engines were increased to larger Isotta-Fraschini, Fiat, or Liberty types for extra lifting capacity. Twenty-three were completed and six were supplied to the R.N.A.S. (where they were on hand April-May 1918), but they did not fly combat missions and were returned to Italy after the Armistice. The Ca.43 was too slow for daylight bombing and quickly moved to night bombing missions instead.
