Royal Italian Air Force

The Royal Italian Air Force (Regia Aeronautica Italiana) was the name of the air force of the Kingdom of Italy. It was established as a service independent of the Royal Italian Army from 1923 until 1946. In 1946, the monarchy was abolished and the Kingdom of Italy became the Italian Republic, whereupon the name of the air force changed to the Italian Air Force (Aeronautica Militare).

Royal Italian Air Force in The War That Came Early
The Royal Italian Air Force had sent volunteers to Spain to help the Nationalists in the Civil War. Although they provided much needed air support to the Nationals, their fighters weren't able to do much against the Soviet Bombers.
