Joaquín García-Morato y Castaño, 1st Count of Jarama was the most successful Nationalist fighter pilot of the Spanish Civil War. He is credited with 40 aerial victories, four gained while flying Heinkel He 51s and 36 with an Italian Fiat CR.32.

The Fiat CR.32 was an Italian biplane fighter used in the Spanish Civil War and the Second World War. Designed by the aeronautical engineer Celestino Rosatelli, it was a compact, robust and highly manoeuvrable aircraft for its era, leading to it being a relatively popular fighter during the 1930s.
