The Bell P-39 Airacobra originally flew with excellent performance but by the time the
plane was far from what Bell had originally designed. They added weight, removed the
supercharger from the Allison engine that didn’t have the power it claimed. What could
have been and should have been one of the best aircraft of WWII turned out to be much
less. Even with all its flaws they still produced 9,584 P-39s.

The Italian Co-Belligerent Air Force was formed in October 1943 after the Italian
armistice a month earlier. The Italian pilots now flew for the Allies and in June and July
1944 received 75 former USAAF 332nd Fighter Group P-39Qs. These aircraft equipped
the Gruppi 9° and 10° of 4° Stormo and the name J. Baracca was to honor an Italian Ace
from WWI. The black prancing horse was used because it was Baracca’s aircraft
emblem. This horse emblem would go on to become the famous Ferrari emblem.
