In 1940, the decision was made to unite the Air Force, the anti-aircraft forces, and the civilian air defense organizations under one central headquarters. Colonel László Háry was retired 24 December 1940, and on 1 March 1941 the new organization was constituted. General András Littay became Air Sub-Department Chief, and Colonel Géza Vörös was appointed Head of the Air General Staff. On 1 June 1941, the Air Defense Corps was established, and Lieutenant General Béla Rákosi became Commander of Army Aviation. In effect the Air Force had once again become part of the Army. In the summer of 1942, an air brigade was attached to the Luftwaffe's VIII. Fliegerkorps on the Eastern Front. Beginning March 1944, Allied bomber raids began on Hungary and progressively increased in intensity. The 101st "Puma" fighter group (later wing) was the elite unit of the MKHL (its name and insignia are carried on by the "Puma" fighter squadron of the Hungarian Air Force of today). Late in 1944 all efforts were redirected towards countering the advancing Red Army, but to no avail. All fighting in Hungary ended on 16 April 1945.
