The article first describes generic Bas 60 standards, then gives Kosta-specific facts. Kosta opened in 1964 with a 2,000 m by 25 m main runway (50,000 m² / 538,196 ft² by direct multiplication), one sealed KC north of the field, UOM southwest and Bakom west. It had six Töreboda aircraft weather shelters excluding two at UOM, hence eight reported shelters in total. Generic Bas 60 facts include 2,000–2,300 m by 30–40 m runways, earth-covered KCs for 6–8 people, 100/200 m³ buried fuel tanks, Sk10/Sk5 shelters for 10/5 lying persons and 1,200–1,500 people on a fully manned base. Those generic values are not proven Kosta quantities.

area_m2: value: 50000 m² / 538,196 ft² | scope: Kosta main-runway paved rectangle | evidence: Derived exactly from the reported 2,000 m length by 25 m width; shoulders, aprons, taxiways and dispersal roads are excluded. | inner_structure: Generic Bas 60 KC: fortified earth-covered bunker with a small blast tunnel; the article does not publish Kosta KC dimensions or confirm every generic detail.; Töreboda arches are aircraft weather shelters, not stated to be bomb-proof bunkers. | other: Kosta runway: 2,000 m long and 25 m wide.; Kosta: six Töreboda arches excluding two at UOM, eight in total.; Kosta site arrangement: UOM southwest, Bakom west and sealed KC north of the main field.; Generic Bas 60 runway standard: 2,000–2,300 m long and 30–40 m wide.; Generic buried fuel tanks: 100 or 200 m³ each.; Generic KC staffing: 6–8 persons.; Generic fully manned base: 1,200–1,500 persons.

amount_sek: 250000000 | price_year: 1958 | scope: national Bas 60 expansion program | note: The plan called for 70 total bases and 31 additional bases. This is not Kosta's construction cost and should not be divided into a unit cost without further scope evidence.

Generic Bas 60 operational command centre and fallback TLF arrangements.; Generic distributed Framom, Bakom and UOM dispersal areas.; Generic buried fuel storage, pipelines and 2,400 L rolling tanks.; Generic ammunition casemates and front/rear ammunition supply.; Generic Sk10/Sk5 personnel shelters and close defence.; Kosta's main runway, KC location and eight Töreboda weather shelters are site-specific.

Runway, shoulders, drainage, lighting, aprons, taxiways and dispersal-road pavement.; Eight aircraft weather shelters and repair/support areas.; Distributed utilities, fuel and ammunition infrastructure.; Small protected KC and communications/airfield mission systems.; Large-area site access, security and integration.

Kosta-specific evidence is limited to the 2,000 x 25 m runway, site arrangement, opening date and eight Töreboda shelters. The 1958 SEK 250m amount and most fuel, staffing, shelter and KC descriptions are Bas 60 program/type evidence.

Revised downward after source-specific review.

Measured runway shoulders, aprons, taxiways and dispersal-road areas.; Dimensions and construction of all eight Töreboda shelters.; Kosta-specific support-building inventory and floor areas.; KC area, shell, entrances and systems.; Kosta-specific fuel tank count/capacity and pipe network.; Ammunition, personnel-shelter, utility and security inventories.; Boundary definition for a minimum documented site versus full mission-equivalent airbase.

The article clearly separates generic Bas 60 description from the Kosta section, but the current estimate imports generic support quantities.; Töreboda arches are described as weather shelters; calling all eight bunkers overstates their protection class.; The current support-building proxy and separate eight-bunker line may overlap.; The national SEK 250m/31-base plan is an aggregate program amount, not Kosta cost evidence.
