F Giulli Caproni Ca183Bis
Caproni team commenced design work on a specialized high-altitude fighter, the CA.183bis. The CA.183bis had a liquid-cooled, 1250-hp DB.605 in the nose, driving contra-rotating six-bladed-bladed contra-rotating propeller. A 700-hp FIAT A.30 V12 engine drove a Campini compressor in a mid-fuselage duct. Scoops in the fuselage sides provided cooling air for the FIAT engine and air mass for the afterburner.
