AKSU, or rather AK-74U (Russian: Автомат Калашникова складной укороченный, Avtomat Kalashnikova skladnoy ukorochennyy, meaning Shortened Folding Kalashnikov Automatic Rifle) is a shortened version of the AK-74 carbine. It is often mistakenly called "AKS-74U", although such a version never officially existed – the designation "S" referred to a variant with a folding stock (in this case – side-folding), but the shortened carbine itself had a different designation.
This compact automatic carbine gained popularity due to its small size and relatively high firepower. Designed for specific applications, it quickly became recognizable worldwide.
Origin of the AKSU: Where did this short AK come from?
The history of the AKSU dates back to the late 1970s, when the Soviet army was looking for weapons with smaller dimensions for vehicle crews, special forces, and other soldiers for whom the standard AK-74 was too large and unwieldy. A weapon was needed that could be easily concealed and used in tight spaces, such as inside vehicles.
Thus, the AK-74U, or AKSU, was born. It was constructed based on the proven AK-74 design, but the barrel was shortened, the muzzle device was changed, and a folding stock was added. The use of the 5.45x39 mm cartridge provided good firepower, and the small size – ease of carrying and maneuvering.
Technical Specifications of the AKSU: What makes it stand out?
The basic features of the AKSU that distinguish it from the standard AK are:
- Shorter barrel: The AKSU barrel is approximately 210 mm long, which significantly affects its compact dimensions.
- Folding stock: Allows reducing the length of the weapon during transport and storage.
- Special flash suppressor: Developed to reduce recoil and muzzle flash resulting from the shorter barrel.
- Caliber: Standard 5.45x39 mm, although there are rarer versions in 7.62x39 mm.
Application of the AKSU: Where was it used and why?
The AKSU found wide application in various military formations and special services worldwide. It was used by, among others:
- Vehicle crews: As a weapon for self-defense in case of leaving the vehicle.
- Special forces: During operations requiring covert action and combat in enclosed spaces.
- Police forces: In situations where a weapon with high firepower but small size is needed.
- Personal protection: By individuals at risk of attack who need a discreet and effective weapon.
Its popularity stemmed from the combination of AK advantages (reliability, ease of use) with compact dimensions, making it an ideal choice for specific tasks.
5.45x39 mm Ammunition: Why this particular caliber?
The decision to choose the 5.45x39 mm caliber for the AKSU was dictated by several factors. First of all, this ammunition is characterized by:
- Flat flight trajectory: Which increases accuracy at longer distances.
- Good stopping power: Despite the smaller caliber than 7.62x39 mm, the 5.45x39 mm projectile tends to rotate in the body, which increases damage.
- Lower recoil: Which makes it easier to control the weapon during continuous fire.
All this made 5.45x39 mm an optimal choice for weapons intended for combat at short and medium ranges.
AKSU vs. other carbines: Comparison and differences
Comparing the AKSU with other carbines, it is worth paying attention to a few key aspects:
| Feature | AKSU | AK-74 | AR-15 (short variant) |
|---|---|---|---|
| Barrel length | 210 mm | 415 mm | approx. 254-368 mm (10-14.5 inches) |
| Caliber | 5.45x39 mm | 5.45x39 mm | 5.56x45 mm NATO |
| Weight (without magazine) | 2.7 kg | 3.3 kg | approx. 2.5-3 kg |
| Application | Close quarters combat, special forces | Universal infantry carbine | Universal carbine, various configurations |
As you can see, the AKSU stands out primarily for its compact size, which affects its application. It is a weapon intended for specific tasks, not a universal infantry carbine.
AKSU in popular culture: Movies, games, and... Tarkov
AKSU, due to its characteristic appearance, often appears in movies, computer games and series. It is particularly popular in FPS (First-Person Shooter) games, where players appreciate it for its accuracy and rate of fire at short distances. An example is the popular game Escape from Tarkov, where AKSU is one of the most frequently used weapons.
