Early Years
First and Second Balkan War
- 12 LVG B.II – reconnaissance aircraft, the first group of six arriving in November 1915. Those two seaters were also used as fighters by the Bulgarians, as dedicated "scouts" were not available.
- 13 Otto C.I – a twin-tailed pusher bomber. The first Otto in arrived in May 1916.
- 18 Albatros C.III – reconnaissance aircraft, also used as trainers. First delivery in August 1916.
- 12 DFW C.V – reconnaissance aircraft, first arriving in August 1917.
- 6 Roland D.II fighters. During July 1917 the first of these arrived with the Section.
- 6 Roland D.III fighters, the first arriving at the end of 1917.
- 3 Fokker E.III fighters, first of these delivered in the spring of 1916.
- 8 Fokker D.VII – the best fighter used by Bulgaria in World War I. Delivery took place in September 1918 and they saw no action. 7 were scrapped in accordance with the peace treaty. The 8th flew as a two-seater after the war.
- 2 Albatros C.I. These were ordered by the Ottoman Empire before Bulgaria entered the war. During early 1915 a couple landed on then neutral Bulgarian territory after a navigational error, and they were seized.

An Aeroflight Section under the Ministry of Railways, Postal Service and Telegraph was created in 1920. Bulgarian aviation personnel assembled two airplanes from hidden spares and parts, salvaged from the destroyed military airplanes. The two aircraft, known as "the mixed planes", recorded about 1000 flight hours altogether. The sole remaining Bulgarian Fokker D.VII was disguised as a two-seater,

- a fighter yato
- a bomber yato
- a recon yato
- a liaison and photographic survey yato
- a maritime yato
- a training orlyak
- a Pilot School at Kazanlak airfield
- a balloon company (which was never actually created, as the balloon was considered obsolete for military purposes at the time).

Order of Battle 1940
The Air Force order of battle comprised the 1st, 2nd, 3rd and 4th Army Aviation Orlyaks (Army Air Groups or air regiments), each attached to the correspondingly-numbered field army. Each orlyak had a fighter, a line bomber and two reconnaissance yatos (Squadrons).
There was also an Independent Aviation corps, which combined the 5th Bomber and 6th Fighter Regiments.
The training units consisted of the "Junker" School Orlyak at Vrazhdebna airfield, the 2nd Training Orlyak at Telish airfield (called the Blind Flying Training School) and the 3rd Training Orlyak at Stara Zagora airfield. In 1940, the Bulgarian aviation industry provided the HMAT with 42 DAR-9, 45 KB-5 aircraft and the serial production of the KB-6 – Bulgaria's first twin-engined aircraft was scheduled to commence.
