The Austro-Hungarian Empire's Luftfahrtruppen contained many pilots from many ethnic minorities. The following list of their World War I flying aces contains those Austro-Hungarian aces identified as ethnic Croatian or born in the territory of modern-day Croatia:
The following are lists of World War I flying aces. Historically, a flying ace was defined as a military aviator credited with shooting down five or more enemy aircraft during aerial combat. The term was first used by French newspapers, describing Adolphe Pégoud as l'as, after he downed seven German aircraft.
Friedrich Hefty, also referred to as Frigyes Hefty, was a World War I Austro-Hungarian flying ace credited with five confirmed and five unconfirmed aerial victories. His early interest in aviation led him to drop out of school in 1913 and become a glider pilot. When World War I began, he served first as an aerial observer, then as a pilot. He scored his first aerial victory as an observer, on 7 October 1915. Once he became a pilot, he claimed nine other victories, four of which were verified. On 22 August 1918, he became one of the first combat pilots to bail out using a parachute. Hefty ended the war with ten awards of the Medal for Bravery.
StabfeldwebelJohann Lasi was a World War I Austro-Hungarian flying ace, a Croat by ethnicity, credited with five aerial victories on 22 Aug 1916, while acting as an unauthorized rear gunner for Julius Arigi.
OberleutnantKarl Patzelt (1893–1918) was an Austro-Hungarian World War I flying ace credited with five aerial victories. Entering World War I as an officer in an infantry regiment, he distinguished himself during the first two years of the war. Decorated twice for valor, he was also honored by a rare early promotion in rank. A serious wound inflicted on 16 June 1916 hospitalized him. While recuperating, he transferred to aviation service. Trained and posted as a technical officer for Flik 29J in Romania, he volunteered to fly as an observer with Andreas Dombrowski. On their missions, Patzelt would benefit from Dombrowski's tuition as a pilot, while downing two enemy aircraft with the observer's gun. In October, Patzelt was transferred to the Italian Front to observe the Battle of Caporetto. By mid-November 1917, he was flying with a fighter squadron, Flik 42J. He would score three more victories before being killed in action on 4 May 1918.
Lieutenant Alois Rodlauer (1897-1975) was a Austro-Hungarian World War I flying ace credited with five aerial victories. Originally a valorous infantry officer in 1915, 1916 and 1917, he turned to aviation in mid-1917. After pilot training, he managed to score five aerial victories between March and October 1918, despite two spells in hospital. Rodlauer returned to civilian life postwar, but returned to serve in the Luftwaffe from 1939 to 1945. He died a natural death in 1975. In 1983, aviation historians pieced together Rodlauer's combat record and realized he was an ace.
FeldwebelKarl Teichmann (1897–1927) was a Austro-Hungarian World War I flying ace credited with five aerial victories. His path to aerial victories began in 1915, when he joined the Austro-Hungarian infantry. His prewar training as an auto mechanic saw him assigned as an aviation mechanic on the Russian Front in February 1916. After eight months, he began pilot training, being awarded Austrian Pilot's Certificate 658 on 16 May 1917. Reassigned to the Italian Front, he scored five victories—three shared—between 26 September 1917 and 22 August 1918. Teichmann would survive the war and die of natural causes in Graz, Austria.
Oberleutnant Josef Pürer (1894-1918) was an Austro-Hungarian World War I flying ace credited with six aerial victories. A volunteer for the artillery when the war began, he fought for two years on the Russian Front. He was commissioned as an officer on 1 January 1916; later that year he transferred to the Austro-Hungarian Aviation Troops. He served as an aerial observer in northern Italy until early 1918. After scoring six aerial victories, he was trained as a fighter pilot by 11 July 1918. He was killed in action by Sidney Cottle on 31 August 1918.

Between 3 December 1916 and 26 June 1917, he was credited with five aerial victories for Fliegerkompanie 19, earning another three decorations. Having taught himself to fly, he transferred to a fighter unit, Fliegerkompanie 51J for his last three victories. On 7 March 1918, Tahy died in a flying accident. His greatest honor came after his death, when he was awarded the Knight's Cross of the Order of Leopold with War Decorations and Swords.
