Caproni Ca. 37, Ca. 38

Caproni Ca. 37

  Basically, the Ca.37 was a smaller version of the Ca.33 with a central fuselage that was shortened, as were the twin booms. There only two rudders located at the end of each boom.
  This version also deleted the nose wheels.There was only one 250-hp Lancia engine mounted as pusher at the end of the nacelle. The crew was reduced to two - a pilot and observer/gunner. The cockpit was provided with armor to reduce injuries from AAA.
  The Ca.37 was listed as a bomber, but the armor makes it more likely that its main function would be ground attack.
  As that mission was currently being carried out by other two seaters and in the case of the SVAs single seaters, it is unlikely that it would accrue any orders. It remained a prototype.

Caproni Ca.38

  Basically identical to the Ca.37 but with a streamline nacelle and tail booms to reduce drag. These changes raised the speed from 165 km/h to 170 km/h. Postwar it was used as a trainer at Caproni’s school in Vizzola Ticino.
