The Avia B-534 was designed and built in Czechoslovakia and entered service in 1935. It was the most advanced biplane of the time, and four variants were built, none of which saw combat for Czechoslovakia due to the invasion and partition of the country in 1939.
The B-534 saw combat with the Slovak Air Force, the Bulgarian Air Force, and was used for training and other duties by the Luftwaffe.
The B-534-I was armed with 2 x 7.92 mm machine guns.
The B-534-II was armed with 4 x 7.92 mm machine guns.
The B-534-III was armed with 4 x 7.92 mm machine guns. It also had a revised air intake and wheel fairings.
The B-534-IV was armed with 4 x 7.92 mm machine guns. It also had an enclosed cockpit along with the revisions on Type III.
There were exceptions to these general versions, and pilots sometimes made ‘field modifications’ including removing the enclosed cockpit and wheel fairings.
