The JA37D, being mainly used for fighter-interceptor purposes, is not equipped with any sort of armour plating against ammunition. While a hit at close range has a high probability of damaging the control systems, a hit from a further distance will probably not cause any considerable damage to the aforementioned controls, however, the fuel tank above the engine does pose a great vulnerability when being fired upon. As a result of the fuel tanks' placement, a fire is a constant threat. Apart from the fuel tanks, the large ailerons are an easy target, and losing a single one will result in loss of control over the aircraft.

Offensive armament

Main article: Akan m/75 (30 mm)

The JA37D is armed with:

  • A choice between three presets:
    • 1 x 30 mm Akan m/75 cannon, belly-mounted (150 rpg)
    • 1 x 30 mm Akan m/75 cannon + 48 x large calibre countermeasures
    • 1 x 30 mm Akan m/75 cannon + 368 x large calibre countermeasures

Suspended armament

Main articles: RB24J, RB71, RB 74, psrak m/70

The JA37D can be outfitted with the following ordnance presets:

  • 1 x 1,250 l drop tank
  • 2 x RB24J missiles
  • 6 x RB24J missiles
  • 6 x RB 74 missiles
  • 2 x RB71 missiles
  • 24 x psrak m/70 rockets

Usage in battles

The JA37D is a highly manoeuvrable aircraft and outperforms most jets in its class, especially at lower altitudes (< 3,000 m). At higher altitudes, the Viggen remains manoeuvrable but, due to its delta-canard configuration, it is prone to losing speed and energy rather fast. This however does not pose much of an issue thanks to the aircraft's effective engine and high rate of acceleration at speeds above 700 km/h and aerodynamics.

In the case of a close range dogfight, you should avoid using AAMs and instead opt for the aircraft's cannon, taking advantage of its high muzzle velocity.

If an enemy positions themselves directly behind you, do not hesitate to use your airbrakes as these are very effective in defensive manoeuvres to regain control of the engagement.

Pros and cons

Pros:

  • Large amount of countermeasures
  • Can carry a drop tank extending the plane's range
  • Good acceleration
  • Can carry highly manoeuvrable missiles, such as the all-aspect RB74 (Swedish license-built AIM-9L) with a 30G maximum overload

Cons:

  • No tracer rounds making it hard to hit enemy aircraft without prior practice
  • Very limited ammo supply with only 150 rounds with no tracer belt options
  • No bombs or guided air-to-ground missiles
  • The afterburner's fuel consumption is overwhelmingly fast

History

The JA37D Viggen is an improved variant of the original JA37 Jaktviggen fighter-interceptor, The D variant of the Viggen first began its production in 1993 and served the Swedish airforce until 2006, with its last flight being in December 2007 during a special air show for the Swedish Air Force. The JA37D features improved, avionics, software systems of the previous JA37C, as a modernization for the ageing airframes.

However one of the main changes for the D variant, were the compatibility to equip and use the Rb 99 Air-To-Air Missile (Swedish designation for the AIM-120 AMRAAM). It could also be equipped with a external ECM pod designated as the "Störkapsel U95".[1][2] This allowed it to serve until the late 2000s, before being completely replaced by the more advanced JAS 39 Gripen jet fighter.
