Darjavna Aeroplanna Rabotilnitza DAR-10F
The DAR-10F was the only Bulgarian-designed military aircraft to have seen service. It was a trim but conservative light bomber with an 840/960-hp Fiat A74RC38 radial, and with spatted wheels and a crew of two under a glasshouse canopy.
The gun armament was heavy: two 20-mm (0.79-in) MG FF cannon in the wings and two 7.92-mm (0.312-in) MG 17 in the top decking, all firing ahead, and an MG 15 in the rear cockpit. In spite of this the 10F could still carry up to 500 kg (1102 lb) of bombs. Darjaviia Aeroplanna Rabotilnitza flew the prototype in 1941 and a small but unknown number entered Bulgarian service.
