The Dornier Do Y was a trimotor German monoplane bomber of the early 1930s designed by Dornier Flugzeugwerke (Dornier Aircraft Works) to an order by the Royal Yugoslav Air Force (RYAF). The Yugoslavs originally intended to use war reparations to pay for them, but ultimately had to use their own funds. Only a pair of aircraft were initially ordered to give the Yugoslavs experience with multi-engine bombers and Dornier failed to sell any more Do Y's. Two improved versions were subsequently built on speculation, but failed to find purchasers until the RYAF bought them in 1935.
All four Do Y's were declared obsolete in 1939 and relegated to training and transport missions. They played no role in the 1941 Invasion of Yugoslavia by the Axis Powers and were captured undamaged. The Germans decided to transfer all of them to the Air Force of the Independent State of Croatia later that year, but only one can be confirmed to have served with the Croatians.
