The DAR 10 served as a Bulgarian aircraft utilised for light bombing and reconnaissance missions.
It was specifically engineered to carry out horizontal and dive bombing, reconnaissance tasks, as well as ground attack operations.
The DAR 10, created by Zvetan Lazarov in 1938 at the DAR factory in Bozhurishte, located near the capital Sofia, was a conventional single-engine, two-seat aircraft with a low-wing cantilever monoplane design.
The aircraft featured tandem seating for the pilot and gunner under enclosed glazing.
Equipped with a fixed tailwheel undercarriage and spatted mainwheels, the wings were constructed with a wooden structure covered in plywood, without the use of flaps.
The fuselage of the DAR 10 was notably wide and deep to house the nose-mounted radial engine, built with a steel-tube framework, wood formers, and fabric covering.
Two prototypes were constructed, each equipped with distinct power sources.
