for pilot training. 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. The Germans gave their captured R-100s to their Croatian allies, who used them for training during the rest of the war. In the initial period the R-100s were used for pilot training, and later were fitted with mountings for a 90–100 kg bomb, and were used for bombing. Several R-100s were used to patrol the outskirts of Zagreb, to repel the attacks of partisan aircraft. The last combat flight of an R-100 was on 26 April 1945. Two R-100s were given to the partisan faction at the end of the war, and two were seized at the Lucko airport near Zagreb during the liberation. All four planes that survived the war are included in the Yugoslav Army Air Force (JRV). 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. The JRV planes remained in use until the 1950s, after which they were retired. A partial R-100 is in the Museum of Aviation at Belgrade Nikola Tesla Airport.
