Report from 1948 (?)
Located two kilometers east of Ljubljana on the north side of the Ljubljana-Zagreb railroad line. The field from northwest to southeast is approximately 1.200 meters long, and could easily be enlarged to the west. The average width of the airfield is 500 meters. The field has a capacity of 150 fighter planes, but thus far not more than 70 planes have been stationed on it at one time. Surface of the field is covered with grass and the ground is very hard, with a layer of only 30 cm of earth on a solid conglomerate. The field is surrounded by a barbed wire fence, two meters high. The main guarded entrance is in the northwest corner of the field, and there is a guarded entrance in the south.
2. Airfield altitude
2..7 (figure illegible) meters above sea level.
As of February 1948, 15 captured German training planes, six of which are Fieseler-Storch's, were parked in hangar 315; ten captured German Messerschmitts, type 109, were parked in hangar 316; ... (number illegible) Russian one-engine fighter planes (type unspecified) were parked in hangar 317; and three Russian three-engine passenger or transport planes (type unspecified) and two U.S. four-engine bombers (type unspecified) were parked in hangar 408.
In one of the hangars were ten Fieseler-Storchs and four Junkers JU-88s.
No Soviet airforce personnel or instructores were attached to this airfield as of February 1948.
5. Guard and Anti-Aircraft Defense
Two MG companies equipped with 18 double-barreled Zbrojevka (Czech) machine guns are attached and placed in unspecified locations on the airfield. There are two AA batteries, one located along the Ljubljana-Kamnik railroad line, close to the village of Jezica, and the second on Golovec Hill at a site known as Crni-Hrid.
6. Operations Tower, Reflectors and Sirens
The airfield as a mobile captured German radio goniometer. There is a siren installed on top of each of the two barracks, and two reflectors on the hangar roof. The airfield receives its electrical power from the Slovene State power line.
The Ljubljana airfield has only one large hangar which was rebuilt by the Italien forces in 1942 after it had been destroyed by the retreating Yugoslavs in 1941. The hangar is approximately 250 x 60 meters and is divided into eight sections. Each section has its own entrance which faces south. Two of the sections are shops for minor aircraft repairs, and another section is used as a deport for spare parts and tools.
8. POL Dump
An unspecified amount of 50-gallon drums are located in the tool and aircraft spare parts depot, while the airfield POL dump is located in the nearby woods about 200 yards north of the hangar.
Two barracks located on the airfield are one-story brick and wooden buildings. They house approximately 150 personnel each, including pilots and mechanics, as well as the office of the airfield commander. Personnel of the two MG companies who are in charge of guarding the airfield, are billeted about 500 yards northeast of the hangar in three small barracks.

An additional area of 750 by 450 meters has thereby been added to the field along the railroad to the south. As of 1 November 1948, this area had not been used for landing of aircraft but was being used as training ground for the Ljubljana garrison. The airfield was also extended to the west to take in an area about 1,000 by 500 meters which had been partly cleared of shrubbery and trees during the Italian occupation.
b. Jakob B... is now deputy airfield commander and political commissar; he is a trained pilot, about 30 years old, born in Ljubljana.

Airfield of Ljubljana, September 1949
1 a. The LJUBLJANA (Y 2/D 31) airfield was located three miles east of the town, north of the railroad line to Maribor. Two hangars, a flight control station, a radio station, quarters, and clubhouses were located on its northern border.
1 b. A road led from the airfield to a fuel dump located to the north. The dump had ten trenches on each side of the road. In each of these trenches fifty gasoline barrels were stored in two rows, one above the other. There was also a 5,500 (?) -gallon gasoline tank. The gasoline dump was not camouflaged against air observation.
2.The airfield was occupied by about 30 fighters of Soviet make (single-engine, single rudder assembly; retractable landing gear; trapezoidal wings) and two biplanes. The pilot students were supposed to leave Ljubljana after receiving their basic training.
3. In a woods, located about one mile north of the Zalog railroad station, about 1,25 miles east of the airfield, there was an air force fuel and ammunition dump, about 1,600 x 1,000 feet, surrounded by a barbed wire fence and strictly guarded. There were one wooden shed for the storage of bombs and four semi-underground fuel tanks with a total capacity of 26,500 gallons. Trenches were being excavated for the storage of gasoline barrels. Numerous earth bunkers were filled up with aircraft and anti-aircraft ammunition.
Comment: The statements on the buildings at the Ljubljana airfield agree with previous reports. The existence of a pilot school is reported for the first time. According to previous information, the 423rd Ground Attack Regiment of the 2nd Air Division is assumed to be stationed in Ljubljana. Another ... confirmed the ammunition and fuel dump east of the airfield.
