Löhr, who had been promoted to Major on 1 July 1920, was accepted into the newly created Austrian Armed Forces on 1 September 1920.
On 15 March 1938, Löhr was transferred to the Luftwaffe, where he became commander of Luftwaffe forces in Austria.
By then he had been promoted to Generalleutnant.
He was commander of Luftflotte 4 in the East from May 1939 until June 1942.

Luftflotte 4 carried out the bombing of Warsaw, Poland in September 1939 and of Belgrade, Yugoslavia in April 1941.
Löhr had developed a plan to bomb Belgrade with incendiary bombs first, so that the fires would help the second, nighttime, attack to find the targets.
This cost thousands of people their lives.
Löhr was promoted to colonel general effective 3 May 1941.
He commanded the 12th Army from 12 July 1942 through to December 1942.
