When the 19th FAR was transformed into 3rd FAB and shifted to ADC Uzundzhovo went along as an independent unit: the 4th Fighter Air Base. Shortly afterwards it changed tasks and hats transferring to the Tactical Air Command as 21st Fighter-Bomber Air Base and finally disbanded. Bezmer Air Base (becoming a joint Bulgarian-American training facility) housed the 22nd Ground Attack Air Regiment (flying Sukhoi Su-25s), which was part of the 10th Combined Air Corps. When the corps transformed into Tactical Air Command the 22nd Ground Attack Air Base transitioned to the new structure. After 26th RAB - Dobrich was de-activated its squadron, flying the dedicated recon planes - the Su-22M-4/UM-3K was transferred to Bezmer where it very briefly operated as an Air Reconnaissance Flight before it disbanded a little more than a year later. Today the 22nd GAAB has two squadrons: 1st Squadron (called "Rattlesnake" or as its patch says "Crotale") and 2nd Squadron (called unofficially "The Khans", because of the traditional Bulgarian insignias of its ancient rulers it has in its patch). The base took intensively part in every joint exercise at home and abroad, held until the time of its establishment. Stara Zagora Air Base used to house the 13th Attack Helicopters Air Regiment (flying 44 Mil Mi-24, of which 6 were of the "V" version and the remainder of the "D") of the 10th Combined Air Corps. As The corps transformed into Tactical Air Command, so did the regiment, becoming an air base. In the late 1990s it disbanded, sending one squadron to the 24th Helicopter Air Base and disestablishing the other one. Krumovo Air Base (military area of Plovdiv Airport) used to house the 44th Helicopter Air Regiment (flying Mil Mi-17s, Mil Mi-8s and Mil Mi-2s) of the 10th Combined Air Corps. According to the major restructuring plans, it became an air base and when 23rd AHAB disbanded, one of its squadrons became 2nd Attack Helicopter Squadron of the 24th HAB. The 1st Helicopter Squadron flies the Mi-17s and the 2nd Helicopter Squadron flies the 12 Eurocopter AS 532AL Cougars delivered from 2006 to 2009. The Bell 206B-3s that were acquired at the end of the 1990s form an Independent Helicopter Training Flight. 24th Helicopter Air Base is also the unit of the armed forces in constant readiness to react upon natural or industrial disasters, providing evacuation or providing emergency response units with air mobility.
