History
The B.135/1 prototype attracted the attention of Bulgarian Air Force officers visiting the Avia plant, and a production contract for 12 aircraft and 62 engines was signed, as well as a license to allow an additional 50 airframes to be constructed by DAR as the DAR 11 Lyastovitsa (Bulgarian: "Лястовица"; "Swallow"). However, the DAR facilities proved to be incapable of producing the aircraft, and only the 12 Czech-built examples were ever made. Plans for further production were stopped by the RLM, which also interrupted engine deliveries after 35 units, and the Bulgarian Air Force was encouraged to purchase the Messerschmitt Bf 109 instead.
Operational history
In service, the B.135s had continual engine problems and were soon relegated to training roles. Four aircraft did, however, see combat on 30 March 1944 when they intercepted USAAF bomber formations encroaching on Bulgarian airspace after attacking Ploieşti. Some (Bulgarian) sources credit Lieutenant Yordan Ferdinandov with a B-24 Liberator kill that morning. According to Bílý, all four Avias, led by Captain Atanasov, took part in the possible shooting down of a four-engined bomber that day. The downed aircraft crashed in the area of Tran and Breznik, according to the log of Lieutenant Yordan Ferdinandov.

Авиа B.135 (чеш. Avia B.135) — чехословацкий одноместный истребитель периода второй мировой войны. Представлял собой моноплан смешанной конструкции с закрытой кабиной и убирающимся шасси с хвостовым колесом. Спроектирован в КБ фирмы «Авиа» под руководством Франтишека Новотны. Являлся развитием конструкции опытного истребителя Avia B.35. Опытный Avia B.35.3 совершил первый полет 20 июня 1939 года. Серийное производство начато уже в условиях немецкой оккупации на заводе «Авиа» в Праге, где было построено всего 12 серийных самолетов, получивших по немецкой номенклатуре обозначение Аv 135. Самолеты были проданы болгарским ВВС где состояли на вооружении с января 1943 года.
