After the outbreak of World War II, in September 1939 two civilian RWD-14 (SP-ALA, SP-KAT) were evacuated to Romania. After the fall of Poland, they were sold by the manufacturer for a fraction of value to Romanian government, and used by Romanian civil aviation (registration YR-FAN and YR-TIT respectively). After Romania joined the war on Axis side and took part in attack on the USSR, RWD-15s were used as liaison aircraft on the eastern front by the Romanian Air Force.
