Aviatik (Berg) D.I - Foreign Users

The Aviatik-Berg D.I saw also postwar service with various nations after the war.

• State of Slovenes, Croats and Serbs & Kingdom of Yugoslavia: After the armistice of 1918 many airplanes were left-over by the Austro-Hungarian troops and were seized by the forces of the newly created State of Slovenes, Croats and Serbs and the Kingdom of Yugoslavia later. They were employed by the Slovenes in the Austro-Slovene conflict in Carinthia of 1918-1919.
• Romania: Apparently the Kingdom of Romania incorporated some D.I after the war. They were most probably MAG made. However any further detail is unknown, so the pic should be considered as purely speculative.
• Hungarian Soviet Republic: Some MAG made Aviatik-Berg D.I were used by the Red Hungarian Air Corps during the revolutionary period of 1919.

Oeffag Va.253 - Foreign Users, first entry

And we keep going with the Albatros D.III variants. This time we are covering some of the foreign users of the Austro-Hungarian most advanced variant, the Oeffag Va.253.

Note: As the Polish air force 7th squadron used a lot of these airplanes, they'll have their own dedicated entry. The Polish airplanes represented here are those not belonging to that squadron.

Powered by a 225hp Austro-Daimler engine, the Va.253 was basically a license-built Albatros D.III featuring some changes which we will explain later.

The countries covered in this entry:

• Austria: After the World War I, the newly created Austrian Republic was banned from having a military air force and therefore most of the former Austro-Hungarian airplanes were scrapped. However some were saved and were owned privately. 
• Czechoslovakia: On 22nd November 1917 the Czech pilot Adolf Blaha, defected to Switzerland where he performed acrobatic shows for living until the Austro-Hungarian Empire collapsed. Then he flew back to Prague and became the first Czechoslovak pilot of the newly created Czechoslovak Army Air Force.
• Poland: After the war the Polish army bought 38 Oeffag Va.253 and employed them in the Polish-Soviet war mainly in ground attack roles. The main user was the 7th squadron, but in this entry we are covering those which didn't serve on the 7th squadron.
• Yugoslavia: The newly created State of Slovenes, Croats and Serbs, seized some leftover Austro-Hungarian airplanes and used them in the Austro-Slovene conflict lasting from November 1918 up to July 1919.
