Bulgaria is arguably the historically most underrated Axis ally that actually fought the Allies during World War 2. Despite remaining outside the main battleground of the war, the Eastern Front, this Balkan country did take its fair share of warfare, particularly due to the combat activity of its fighter air force against the armada of US bombers and their fighter escorts, in 1943 and 1944. Then, following an about-face in early September 1944, the Bulgarians combatted their former ally, the Germans. This notable air activity is largely unknown outside Bulgaria, and is not very much popularized even within the country, despite fully deserving the utmost attention.

This two-volume book describes and illustrates all the fighter and fighter trainer aircraft used by the Bulgarian armed forces before, during, and shortly after WW 2. These aircraft were procured from the following countries: Germany, Poland and Czechoslovakia. Emphasis is placed on the most potent German fighter types, the Messerschmitt Bf 109E and G, as well as the top-notch fighter type of France, the Dewoitine D.520. However, rare, exotic models, including the sole locally built prototype that fits the definition, the DAR-5, are also included.

The camouflage and markings, as well as the military coding system of these large variety of aircraft types are described in great details. Fully illustrated with many rare photos, most of them seen for the first time in print. Mutinously detailed colour profiles of many representative aircraft type are included as well.

Summing up, this lavishly illustrated, full-colour two-volume book, spanning across over 600 pages, is the reference work of the fighter and fighter trainer aircraft, as well as the pilots who flew for the Royal Bulgarian Air Force prior to, during, and shortly after World War 2.
