Bas 60 (Flygbassystem 60, Air Base System 60) was an air base system developed and used by the Swedish Air Force during the Cold War. The system was based around defensive force dispersal of aircraft and its supporting ground operations across many krigsflygbaser (wartime air bases) in case of war, primarily as a protective measure against nuclear weapons. The purpose of the system was to make it complicated for an opponent to destroy the Swedish Air Force on the ground and thus ensure endurance for the air force in a conflict scenario. The plan was to disperse the air units so one krigsflygbas would house one squadron (8-12 aircraft). This dispersion principle also applied to the individual wartime bases themselves, meaning that the various functions of an air base were spread over a large area in and around the base.
The system originated from an air force inquiry in 1954 and was formally implemented in the 1958 defence plan. The original plan called for 70 wartime air bases to be built, with 46 of them to be equipped for continuous usage. The number of bases was however reduced with every revision of the plan and about 40 bases ended up being completed.
During peace time the air squadrons were stationed at their respective air wing and deployment to the wartime air bases would only occur when the threat level increased. But many of the air wings also doubled as wartime air bases. The wartime air bases were only manned by a smaller bastropp (base troop) during peace time and the full base battalion would only be manned with a mobilization (except during certain exercises). This was because the majority of the units were made up by conscripts. The base system was therefore never fully active during the time it existed, like the rest of the Swedish Armed Forces during the Cold War.
A wartime air base in the Bas 60 system functioned as ordinarie bas (regular base), shortened as "O-bas" (R-base), for one or more type of aircraft; fighter, attack or reconnaissance. A regular base had the personnel and resources needed for maintaining and repairing the type of aircraft assigned to that base. Some bases also doubled as temporär bas (temporary base), shortened as "T-bas" (T-base), for one or more aircraft types. A temporary base only had capacity to refuel and rearm the type of aircraft it acted as temporary base for. All regular bases acted as temporary bases for fighter aircraft.
Road runways were also built to complement the wartime bases, acting as a backup bases. Civilian airports could also be used as a backup alternative.
The system was further developed into Bas 90 during the 1970s and 1980s.
The main runway was a typical runway at a length of 2,000–2,300 metres (6,600–7,500 ft) and 30–40 metres (98–131 ft) wide, with a taxiway running parallel to it. Visual aids for pilots such as runway lights were installed. At the ends of the runway there were raisable and lowerable nets for capturing aircraft that were not able to take off or land properly.
Främre klargöringsområde (framom), fore flight line position, was the flight line position (apron) by the main runway, and was where fighter aircraft were to be prepared for missions and be on standby. A base usually had two framom positions, one located at each end of the main runway. One framom position had space for four aircraft. Attack and reconnaissance aircraft in need of complementary refueling could also be refueled at framom. Fighter aircraft on standby at framom were directly connected to the bases communication net so the pilots could receive orders directly and take off immediately after receiving the order. When no aircraft were at framom, the groundcrew would evacuate the area as a safety measure and return when new aircraft came in.
Bakre klargöringsområde (bakom), rear flight line position, was the flight line position for attack and reconnaissance aircraft. Bakom was located 2–3 kilometres (1.2–1.9 mi) away from the main airfield and only bases that were regular bases for attack and reconnaissance aircraft had a bakom position. In case a base was a regular base for both attack and reconnaissance there were two separate bakom positions, referred to as bakom-attack (rear-attack) and bakom-spaning (rear-reconnaissance). A bakom position had 10-15 individual aircraft spaces (hardstands) with a distance of 50 metres (160 ft) between each space, and aircraft currently in bakom were to be separated as much as possible within the available aircraft spaces. This was to reduce the risk of having all aircraft destroyed in a single attack. The aircraft spaces could also be concealed with camouflage nets. Bakom was connected to the main airfield via a taxiway that in many cases was public road integrated into the base infrastructure, and aircraft could either taxi on their own between the sections of the base or be towed by a vehicle.
Uppställningsområdet (uom), staging area, was where aircraft undergoing long-term maintenance, such as repairs, or not being in immediate use were kept. Uom was located 5–10 kilometres (3.1–6.2 mi) away from the main airfield. A uom had field hangars for maintenance work and a site for engine swapping and testing. Just like at bakom the aircraft spaces at uom could be concealed with camouflage nets and was connected with the rest of the base via a taxiway that often was public road. Most of the aircraft groundcrew and their equipment would be positioned at uom.
To complement the ordinary Bas 60 bases, reservvägbaser (road runways) were built to act as a backup alternative. Selected sections of public roads that were suitable for the purpose were widened to give enough space for aircraft to take-off and land. The typical dimensions for a reservvägbas (road runway) was 1,500–2,000 metres (4,900–6,600 ft) in length and 12 metres (39 ft) in width. One or two runway aprons were built near each end of the runway. About 30 road runways were built, primarily in the southern and eastern parts of Sweden. Usage of the road runways were limited by adverse light and weather conditions, which is why they were primarily considered a backup alternative. Utilizing a road runway required relocating units and resources from an ordinary base, and certain field works around the runway were often necessary before it could be used.
Selected civilian airports were later added as additional reserve bases.
The air traffic operations on a base were led and organized from a kommandocentral (command centre), abbreviated as KC, located in an underground bunker a few kilometers away from the airfield. A KC was manned by 6-8 people, including the duty officer.
Trafikledaren vid fältet (TLF), the traffic leader at the field, was stationed at the main runway and assisted the air traffic operations. In case kommandocentralen was unavailable or stopped functioning the TLF could take over control of air traffic operations. The TLF operated from a special cart that was equipped with base radio, air traffic radio, telephone and controls for runway functions such as lighting.
The overarching and long term operations on base were led and organized from a stabsplats (command post). This command post would be located in one or more buildings (often a school) in a nearby town or city. The stabsplats also acted as the camp for many of the base units, including the medical, meteorology and security units.
One base was operated by a basbataljon 60 (base battalion type 60), with the battalion chief in charge of the overall operations on the base. A fully mobilized battalion consisted of 1200-1500 men, but in peace time a base was normally operated by 2-3 technical officers and 10-15 conscripted flight mechanics. During larger exercises all or part of the full base battalion would be called in.
One base battalion consisted of the following units:
The defense of the base could also be reinforced with infantry and anti-air units from the Swedish Army.
In the 1970s and 1980s the Bas 60 system was developed into Bas 90 to accommodate new needs and threats.
With the end of the cold war the Bas 60 and Bas 90 system was scrapped, and many of the wartime air bases have been demilitarized and sold to civilian owners.

The Bas 60 road runways are not to be confused with the short runways in the Bas 90 system, which in many cases also were built on public road. The Bas 90 short runways belonged to a larger air base and were therefore not counted as individual bases, unlike the Bas 60 road runways.

The Saab 37 Viggen is a single-seat, single-engine multirole combat aircraft designed and produced by the Swedish aircraft manufacturer Saab. It was the first canard-equipped aircraft to be produced in quantity and the first to carry an airborne digital central computer with integrated circuits for its avionics, arguably making it the most modern/advanced combat aircraft in Europe at the time of introduction. The digital central computer was the first of its kind in the world, automating and taking over tasks previously requiring a navigator/copilot, facilitating handling in tactical situations where, among other things, high speeds and short decision times determined whether attacks would be successful or not, a system not surpassed until the introduction of the Panavia Tornado into operational service in 1981.
The Saab 35 Draken is a Swedish fighter-interceptor developed and manufactured by Svenska Aeroplan Aktiebolaget (SAAB) between 1955 and 1974. Development of the Saab 35 Draken started in 1948 as the Swedish air force future replacement for the then also in development Saab 29 Tunnan dayfighter and Saab 32B Lansen night fighter. It featured an innovative but unproven double delta wing, which led to the creation of a sub-scale test aircraft, the Saab 210, which was produced and flown to test this previously-unexplored aerodynamic feature. The full-scale production version entered service with frontline squadrons of the Swedish Air Force on March 8, 1960. It was produced in several variants and types, most commonly as a fighter-interceptor.
The Swedish Air Force is the air force branch of the Swedish Armed Forces.
Offensive counter-air(OCA) is a military term for the suppression of an enemy's military air power, primarily through ground attacks targeting enemy air bases: disabling or destroying parked aircraft, runways, fuel facilities, hangars, air traffic control facilities and other aviation infrastructure. Ground munitions like bombs are typically less expensive than more sophisticated air-to-air munitions, and a single ground munition can destroy or disable multiple aircraft in a very short time whereas aircraft already flying must typically be shot down one at a time. Enemy aircraft already flying also represent an imminent threat as they can usually fire back, and therefore destroying them before they can take off minimizes the risk to friendly aircraft.
A hardened aircraft shelter (HAS) or protective aircraft shelter (PAS) is a reinforced hangar to house and protect military aircraft from enemy attack. Cost considerations and building practicalities limit their use to fighter size aircraft.
Operation Focus was the opening airstrike by Israel at the start of the Six-Day War in 1967. It is sometimes referred to as the "Sinai Air Strike". At 07:45 on 5 June 1967, the Israeli Air Force (IAF) under Maj. Gen. Mordechai Hod launched a massive airstrike that destroyed the majority of the Egyptian Air Force on the ground. Following Syrian and Jordanian attacks in retaliation, the Israeli Air Force proceeded to bomb air bases in those countries. By noon, the Egyptian, Jordanian and Syrian Air Forces, totaling about 450 aircraft, were destroyed. It was also very successful in disabling 18 airfields in Egypt, hindering Egyptian air operations for the duration of the war, and remains one of the most successful air attack campaigns in military history.
Operation Daisy was a military operation conducted from November 1–20, 1981 by the South African Defence Force and South West African Territorial Force (SWATF) in Angola during the South African Border War and Angolan Civil War. This conflict was sparked when the South African Defence Force decided to try to halt the regroup of the active military branch of SWAPO, also known as the People's Liberation Army of Namibia.
Laon-Couvron Air Base is a former French and United States Air Force base in France. It is located in the Aisne département of France, less than one mile southeast of the village of Couvron and 6 miles northwest of Laon; on the southwest side of the Autoroute des Anglais 1 Mile (1.6 km) east of the village of Couvron-et-Aumencourt.
15,5 cm bandkanon 1, meaning "15.5 cm (6.1 in) tracked cannon 1", was a Swedish self-propelled artillery vehicle in use with the Swedish Army from 1967 to 2003, developed by Aktiebolaget Bofors. Its product name was Bofors Vagnkanon 155 mm L/50, meaning roughly "Tracked Automotive Gun 155 mm L/50". Bkan 1 was one of the world's heaviest and most powerful self-propelled artillery vehicles in use during its service.
[Swedish] Tactical and Air Defence Control System in forms of STRIL 50 and STRIL 60 were integrated systems for aerial warfare control including early warning radar and ground-controlled interception. The systems depended on radar and radio as primary technologies but STRIL 50 was based on manual control while STRIL 60 applied the usage of early digital computers.
A highway strip, road runway or road base is a section of a highway, motorway or other form of public road that is specially built to act as a runway for (mostly) military aircraft and to serve as an auxiliary military air base. These runways allow military aircraft to continue operating even if their regular air bases, some of the most vulnerable targets in any war, are degraded or destroyed.
Saint-Simon – Clastres Air Base is an abandoned military airfield, which is located approximately 3 km (2 NM) northwest of Clastres and east of Saint-Simon, both communes in the Aisne department of the Picardy (Picardie) region in France. It is approximately 116 km (63 NM) north-northeast of Paris.
Laon-Athies Air Base is an abandoned military airfield, which is located near the city of Laon in the Aisne department of France.
Péronne-St Quentin Airfield is a recreational aerodrome in France, located 18 km (11 mi) west of Saint-Quentin; 195 km (121 mi) north of Paris. It supports general aviation with no commercial airline service scheduled.
Giebelstadt Army Airfield is a closed military airfield located in Germany, southwest of Giebelstadt in Bavaria, approximately 250 miles southwest of Berlin. It was turned over to the German government on 23 June 2006 and is now Giebelstadt Airport, a general aviation airport.
Air force ground forces and special forces are the land warfare forces of an air force. They may include infantry, special forces, security forces, and military police. Airmen assigned to such units may be trained, armed and equipped for ground combat and special operations.
The 1st Air Command, previously named Air Command and later named Attack Command was an air group unit in the Swedish Air Force. The 1st Air Command was the collective name given to the attack wings who would jointly carry out heavier attacks in the event of war. It was active in various formations from 1938 to 1995. It was directly subordinate to the Supreme Commander of the Swedish Armed Forces and therefore nicknamed ÖB:s klubba.
Bas 90 was an air base system used by the Swedish Air Force during the Cold War. Bas 90 was developed during the 1970s and 1980s from the existing Bas 60 system in response to the new threats and needs that had arisen since the conception of the Bas 60 system during the 1950s. Like its predecessor, the Bas 90 system was based around defensive force dispersal of aircraft across many krigsflygbaser in case of war, as well as dispersion of the air base functions within the individual bases themselves. The air units would have been dispersed so one squadron would be stationed per krigsflygbas. The system was a protective measure against nuclear weapons and airstrikes, the purpose being to make it complicated for an opponent to destroy the Swedish Air Force on the ground and thus ensure endurance for the air force in a conflict scenario.
Major General Erik Gustav Vilhelm Nygren was a Swedish Air Force officer. Nygren's senior command was Chief of the Air Staff from 1978 to 1980 and Commanding General of the Attack Command from 1980 to 1983.
The Defence Act of 1958 was a defence act passed by the Swedish Riksdag on 4 February 1958. It was made with Prague Coup, Korean War and Hungarian Revolution of 1956 as a background, where the threat of nuclear weapons, adaptability and possible acquisition of a Swedish nuclear weapon also played a role.
