Description

The AIM-92 Stinger missile with fins folded and deployed (scale is approximate)


The AIM-92 Air-to-Air Stinger is an American infrared homing air-to-air missile. It was introduced in Update 1.91 "Night Vision". It is a helicopter-mounted variant of the well known FIM-92 Stinger fire-and-forget shoulder-fired anti-air missile.

Effective damage

The damage of the missile is poor to say the least, it requires a direct hit on a vital part like the engines or fuel tanks in order to do significant damage. Helicopters can be hit in the main fuselage by the Stinger with minimal damage to the flight performance. Securing a hit to a vital component is essential.

Comparison with analogues

The missile is identical in many points to the Soviet 9M39 Igla. Its top speed is higher, and it only has a slightly longer guidance time and a slightly larger explosive mass.

Usage in battles

This missile is designed with helicopter-based air to air combat in mind, with an emphasis on defence against strafing attacks by jets. The Stinger allows the helicopter to counterattack an aircraft that is quickly closing in, usually destroying or crippling it before it can fire. It is also useful against other helicopters, and its longer lock-on range than most IR missiles will give it a competitive advantage.

Pros and cons

Pros:

  • Best lock-on range of all helicopter IR missiles
  • All-aspect tracking

Cons:

  • Worse tracking than other missiles of its class
  • Abysmal explosive mass compared to contemporaries

History

ATAS

An ATAS armament arrangement on the stub-wing of a EC-665 Tiger UHT.

During the 1980s, around when the improved Stinger-RMP models became operational, these missiles were used as a basis for air-to-air weapons on aerial mounts. These adapted missiles are officially recognized as ATAS (Air To Air Stinger). The missiles were initially designed and mounted onto OH-58 Kiowa observation helicopters for self-defence against enemy air targets.[1] Though the Stinger is sometimes referred to as AIM-92 in the air configuration, it has been suggested that this naming is unofficial and that the ATAS is still referred as a FIM-92.[2]

As with the standard Stinger-RMP, the ATAS were also upgraded in similar fashion. The first was the Block I modification which introduced improvements such as the removal of the need to "super-elevate" the missile (the additional elevation angle added to the missile's line-of-sight).[3] The second improvement was the Block II modification which introduced a new seeker, a new battery, and advanced signal processing capabilities. These upgrades aim at improving the missile's shelf life, missile accuracy, night-fighting capability, and IRCCM capability.[4]
