History of the Development of the Saab 105

During the 1960s, amidst escalating global tensions, Sweden felt the imperative to modernize its military aviation capacities. The Swedish Air Force needed an aircraft versatile enough for multiple roles—primarily for training but also capable of reconnaissance and light attack.

Saab, already a prominent name in Swedish aviation, was tasked with the challenge. The objective was clear: Develop an affordable, efficient, and versatile jet trainer that could also double up in other capacities when needed. Thus, the Saab 105 was conceived and made its maiden flight in 1963.

Design of the Saab 105

Constructed primarily of aluminum, the Saab 105 features a sleek design, with a low straight wing and a T-tail. Its cockpit, designed for two crew members, offers ejection seats and a clear bubble canopy for expansive visibility.

Technical Specifications:

  • Length: 10.5 meters (34 ft 5 in) / Wingspan: 9.5 meters (31 ft 2 in)
  • Empty weight: 2,750 kg (6,050 lb) / Max takeoff weight: 4,635 kg (10,220 lb)
  • Engine: Two Turbomeca Aubisque turbofan engines.
  • Maximum Speed: 970 km/h (600 mph) or Mach 0.9.

The aircraft’s compactness gave it agility, while its twin engines ensured redundancy and reliability. However, a notable drawback was its limited range without external fuel tanks. But its design facilitated adaptability, enabling the Saab 105 to easily transition between roles.

Performance of the Saab 105

The Saab 105’s performance metrics, particularly its agility and speed, made it an ideal trainer, simulating the characteristics of more advanced combat jets.

  • Range: 2,200 km (1,367 miles) with external tanks.
  • Service Ceiling: 13,100 meters (43,000 ft).
  • Rate of Climb: 30 m/s (5,900 ft/min).

Compared to its counterparts, the Saab 105 was not the most powerful or the fastest. However, its versatility, combined with the reliability of its engines and its efficient avionics, ensured its continued relevance in the Swedish Air Force and beyond.

Military Use and Combat of the Saab 105

Originally intended as a trainer, the Saab 105’s military capacities soon became evident. The aircraft was equipped with hardpoints, allowing it to carry a variety of weapons.


  • Guns: Adaptable for cannons.
  • Missiles: Capable of carrying air-to-air and air-to-ground missiles.
  • Bombs: Equipped for various bombs, including napalm and cluster bombs.

While the Saab 105 never saw extensive combat in major conflicts, its role as a reconnaissance and light attack jet was pivotal during various Cold War-era border skirmishes and surveillance missions. Furthermore, its adaptability saw it being utilized for target towing and electronic warfare exercises.

Sweden was the primary operator, but the aircraft did find an international customer in Austria, which utilized it extensively for training and border patrol tasks.

While more modern aircraft have since replaced the Saab 105 in many roles, it continued its service into the 21st century. The legacy of the Saab 105 remains in its testament to Swedish engineering and its multi-role adaptability.

The Saab 105 underscores the essence of Swedish aerospace design—efficiency, adaptability, and reliability. Its journey from a jet trainer to a multi-role aircraft illuminates the evolving needs and innovations of military aviation. While it may not be as renowned as some combat-centric jets, the Saab 105 remains an indelible part of aviation history, serving as a bridge between training and operational combat for countless pilots.
