 In fact, the Ro.37 continued to be used as reconnaissance aircraft for years, since its replacement, the Caproni Ca.311, proved unsatisfactory.Ro.37s were also quite widely exported (ten to Uruguay, 16 to Afghanistan, 14 to Hungary, eight to Austria, and one to Ecuador) and about 280 were in service in 1940, in thirty squadrons consisting of 215 aircraft.Some were in service up to 1943 and perhaps even later.
