NOTE: This article is about North Vietnamese 9K32 Strelas in ArmA 3's S.O.G. Prairie Fire Creator DLC. For 9K32 SAMs in the main ARMA games, see Strela-2 9K32.


« The 9K32 Strela-2 'Arrow' (SA-7) is a portable, reloadable launcher capable of firing a 72mm infra-red surface-to-air missile up to 3500m. A later variant the Strela-2M (SA7b) has a greater range of 4,200m. It became the first portable Soviet MANPADS, entering service in 1968 with large scale production starting in the 1970s.

The 9K32 Strela-2 is a 72 mm surface-to-air missile launcher used by both the PAVN and Viet Cong guerillas in ArmA 3. It was added with the release of the S.O.G. Prairie Fire Creator DLC.

Overview[]

This section is a stub. You can help Armed Assault Wiki by expanding it.

The 9K32 Strela-2 (NATO reporting name: SA-7 Grail) is a shoulder-launched, fire-and-forget surface-to-air missile launcher.

It loads infrared-guided missiles fitted with 72 mm high-explosive (HE) warheads[CfgAm 1] that are capable of striking both rotary-wing and low-flying fixed-wing aircraft flying at speeds of up to 900 km/h[CfgAm 2][Formula 1] at distances between 100-3,500 metres.[CfgAm 3][CfgAm 4]

The launcher can be aimed using the launcher's (non-magnified) ironsight. It takes six seconds to acquire a successful lock onto a target.[CfgWp 5] Flare-based countermeasures have a 60% chance of temporarily disrupting the launcher's lock-on.[CfgWp 6]

Variants[]

The 9K32 Strela-2M is an upgraded iteration of the baseline 9K32 launcher that specifically fires enhanced Strela-2M missiles.

Compared to its parent model, the Strela-2M takes one second less to lock onto targets (5 seconds rather than 6 seconds).[CfgWp 11] The Strela-2M missile's warhead is ~ 38% more powerful[CfgAm 5], deals ~ 33% more splash damage[CfgAm 6] (though blast radius remains unchanged), fly ~ 15% faster[CfgAm 7], and has slightly better mid-flight manoeuvrability.[CfgAm 8] Meanwhile, its IR sensor has a ~ 21% boost in acquisition range, increasing from a maximum of 3,400 metres on the baseline (non-M) Strela-2 to 4,200 metres.[CfgAm 9]

However, its actual lock-on range remains unchanged at 100-3,500 metres.[CfgAm 10][CfgAm 11] This similarly applies to all other aspects of the launcher and its missiles which remain identical to the baseline (non-2M) 9K32. It should also be noted that it is not possible to load non-2M missiles into the launcher and vice versa.[CfgWp 12]

Sight[]

Arma3-sogp9k32strela2-ironsight-overview
The 9K32 Strela-2's ironsights are set to a fixed zeroing of 300 metres[CfgWp 13], though this does not actually affect the missile's lock-on capabilities.

Due to the missile's seeker having a lock-on cone of only 4 degrees, the target aircraft must be positioned inside the middle of the ironsight's circle in order to continue locking on initially.[CfgAm 12] Once a lock has been successfully acquired, lock-ons can be maintained up to the outer edge of the ironsight's circle as its off-boresight limit extends to a maximum of 75 degrees (but no more).[CfgAm 13]

Munitions[]

There are two types of missiles available, though 9K32 launchers are restricted to loading only one type of missile depending on their model (i.e. 9K32 Strela-2Ms cannot load non-M missiles[CfgWp 12] and vice versa[CfgWp 15]):

Sensors[]

The seeker on the 9K32 missiles utilise only one type of sensor for guidance. However, their specifications vary depending on the missile's model, whether it is the baseline non-M Strela-2 or is the enhanced Strela-2M missile:


Strela-2: Infrared Sensor[]

Sensor type Max range (Air/Ground) Min range (Air/Ground) Affected by environment? Target max speed (km/h) Azimuth coverage (°) Elevation coverage (°)
Infrared A: 3,400 m
G: 2,000 m
[CfgAm 36][CfgAm 37]
A: 100 m
G: 500 m
[CfgAm 38][CfgAm 39]
Fog (0.005%)
[CfgAm 40]
792 km/h
[CfgAm 41][Formula 2]
120°[CfgAm 42] 65°[CfgAm 43]

The missile can lock onto targets between 100[CfgAm 3]-3,500[CfgAm 4] metres away, and is only able to track aircraft that are flying at speeds of up to 720 km/h.[CfgAm 41][Formula 2][note 3] The sensor's lock-on cone is restricted to a horizontal angle of 120 degrees[CfgAm 42] and a vertical angle of 65 degrees.[CfgAm 43]

Although it is technically affected by heavy fog, the range reduction effect is so miniscule (17 metre reduction[CfgAm 40]) that it will be barely noticeable.[note 4] It should be noted that there is no minimum altitude requirement for lock-ons; aircraft can immediately be locked onto as soon as they emit enough heat and begin to take off from the ground.[CfgAm 44]

Strela-2M: Infrared Sensor[]

Sensor type Max range (Air/Ground) Min range (Air/Ground) Affected by environment? Target max speed (km/h) Azimuth coverage (°) Elevation coverage (°)
Infrared A: 4,200 m
G: 2,000 m
[CfgAm 9][CfgAm 45]
A: 100 m
G: 500 m
[CfgAm 46][CfgAm 47]
Fog (0.005%)
[CfgAm 48]
936 km/h
[CfgAm 49][Formula 3]
120°[CfgAm 50] 65°[CfgAm 51]

The missile can lock onto targets between 100[CfgAm 10]-3,500[CfgAm 11] metres away, and is only able to track aircraft that are flying at speeds of up to 936 km/h.[CfgAm 49][Formula 3][note 5] The sensor's lock-on cone is restricted to a horizontal angle of 120 degrees[CfgAm 50] and a vertical angle of 65 degrees.[CfgAm 51]

Although it is technically affected by heavy fog, the range reduction effect is so miniscule (21 metre reduction[CfgAm 48]) that it will be barely noticeable.[note 4] It should be noted that there is no minimum altitude requirement for lock-ons; aircraft can immediately be locked onto as soon as they emit enough heat and begin to take off from the ground.[CfgAm 52]

Trivia[]

  • Both the PAVN and Viet Cong forces do not utilise handheld Strela-2Ms in normal gameplay but their rotary-wing aircraft are capable of mounting the improved missile on stub wing pylons.

Formulae

  1. missileLockMaxSpeed * 3.6 = 250 * 3.6
  2. 2.0 2.1 maxTrackableSpeed * 3.6 = 220 * 3.6
  3. 3.0 3.1 maxTrackableSpeed * 3.6 = 260 * 3.6

Notes[]

  1. 1.0 1.1 The missile's warhead is purely explosive and cannot pierce armour.
  2. 2.0 2.1 If available, Strela missiles can be detected by the target's Infrared Warning Receiver (IWR) during lock-on and by its Missile Approach Warning System (MAWS) once the missile is in the air and is flying towards it.
  3. This lower maximum speed value (720 km/h) only applies to the missile's infrared sensor. The missile itself (when it is still loaded in the launcher) can lock onto targets that are flying at speeds of up to 900 km/h.
  4. 4.0 4.1 The missile's infrared sensor IS affected by the player's View and Object Distance settings and may not function at its maximum range unless their graphics settings are set to an equal or higher distance.
  5. This higher maximum speed value (936 km/h) only applies to the missile's infrared sensor. The missile itself (when it is still loaded in the launcher) can only lock onto targets that are flying at speeds of up to 900 km/h.
