The Rogožarski R-100 (Serbian Cyrillic:Рогожарски Р-100, transliterated as Rogožarski R-100 in German and as Rogojarsky Р-100 in some older English sources) was a single-engined, single-seat parasol winged aircraft designed as an advanced and fighter trainer built by Rogozarski in Yugoslavia before World War II.
After that, 11 R-100s were used by the newly formed Air Force of the Independent State of Croatia, sometimes as ground attack aircraft, and one R-100 was used by the Italian Regia Aeronautica.
The Prva Srpska Fabrika Aeroplana Živojin Rogožarski A.D. was the first Serbian aircraft manufacturer in Yugoslavia, founded in 1924.
Its ailerons were full-span, narrow-chord, fabric-covered metal-structure units, with prominent spades above the wing's upper surface.
[3][4] At the time of the Italo-German invasion of Yugoslavia in April 1941, the Italians seized one R-100, the Germans took another eleven; the remaining aircraft were destroyed.
One each was used by the 111th and 112 Fighting regiment, the third was used in the VTC (Aeronautic Technical Center) and the fourth was used by the commander of 4th bomber division.
