When the 10th Mixed Air Corps was formed in 1961 the 16th Transport Air Regiment was part of it, but later it was subordinated directly to the Air Force and Air Defence Forces Headquarters, as the regiment was planned to form Directorate of the Military Transport and Specialised Aviation (Управление на Военнотранспортната и Специалната Авиация (ВТА и СА)) during wartime, when the national airline BGA Balkan would have been mobilized.
The two air defence divisions were coordinated by an Air Defence Command Post in Sofia. The separation line between their areas of responsibility ran along a line from Ruse through Nova Zagora to Svilengrad.
