In 1975, a special underwater assault rifle (APS) was adopted to arm combat swimmers of the USSR Navy.

The APS assault rifle is the personal weapon of a combat swimmer and is designed to engage underwater and surface targets, as well as for protection against sea predators.

The development of weapons began in the 70s at the Central Research Institute of Precision Engineering (TSNIITOCHMASH) by designer V.V. Simonov. Designers O.P. Kravchenko and P.F. Sazonov developed a special cartridge. The MPS cartridge bullet is a steel rod with a narrowing head in the shape of a double truncated cone. The cartridge case is of a traditional design, it contains a propellant powder charge, ejecting a bullet from the barrel and activating the automatic weapon, based on the use of the energy of gases removed from the hole in the barrel wall. Stabilization of a bullet in water is carried out due to the formation around the bullet during movement. cavitation cavity. The formation and retention of a cavitation cavity is ensured by appropriate selection of the shape and size of the bullet and its speed. The barrel of the machine gun is smooth, has no rifling, and the bullet does not mechanically interact with the barrel. The bullet does not stabilize in air. In addition to the main cartridge, an MPST cartridge with a tracer bullet has been developed. The machine's ammunition is created using a standard 5.45 mm steel case of the domestic 5.45 mm machine gun cartridge, caliber of rifled barrels along the fields. The diameter of the 5.45 mm barrels along the rifling is 5.66 mm, the same is the nominal diameter of the leading part of the bullets of 5.45 mm machine gun cartridges. The diameter of the steel bullet of the APS assault rifle corresponds to the outer diameter of the cartridge bullet of 5.45 x 39 mm. But since the MPS bullet does not cut into the rifling, the caliber of the APS barrel corresponds to the outer diameter of the bullet and has the corresponding designation 5.66 mm. And, probably, this circumstance, combined with the often poor visibility under water, led to the need to include an MPST cartridge with a tracer bullet in the ammunition load, which makes it possible to adjust shooting along the routes.

Automatic APS works by using the energy of powder gases removed from the hole in the barrel bore. To ensure the weapon operates both under water and in air, in environments of such different densities, the gas outlet unit is equipped with a regulator. With its help, you can change the amount of exhaust gases and, accordingly, the speed of movement of the moving parts. However, when firing in the air, the survivability of the machine gun decreases sharply and amounts to 180 shots (2000 shots under water). The trigger mechanism with a rear sear allows for single and continuous fire. The impact mechanism is striker-fired. The barrel is locked by turning the bolt.

The significant dimensions of the cartridges along the length lead to the need to introduce additional devices into the design of the weapon to ensure it reliable operation. The machine's magazine has spring grips in the front part that prevent the bullets from skewing upwards, and a cartridge separator. A cut-off device is placed in the receiver to prevent several rounds from being fed into the chamber at the same time. The unusual shape of the magazine is explained by the fact that the feeder spring is short compared to the cartridges.

Taking into account the positive experience in solving problematic issues After testing the underwater pistol complex in 1970, TsNIITOCHMASH was given the task of creating underwater automatic small arms to equip underwater vehicles of the Triton-1M type and arm combat swimmers (as an individual weapon). On a competitive basis, the designers of TsNIITOCHMASH began to work on the design of an underwater machine gun and an underwater machine gun, and the designers of the Tula TsKIB SOO began to work on the creation of an underwater machine gun.

As in the work on the pistol, research and development work began with the development of an automatic cartridge for underwater shooting. In the new automatic cartridges for underwater shooting, developed by designers P. F. Sazonov and O. P. Kravchenko using the cartridge case of the standard 5.45 MM 7N6 cartridge, the problem of achieving a high initial velocity of bullets and ensuring their stable movement along the trajectory was successfully solved. The MPS cartridge was a standard 7N6 cartridge case into which a 120 mm long needle-shaped bullet was inserted. When moving under water, the bullet was also stabilized due to the appearance of a cavitation bubble (cavity) in the head part. In the air, such a bullet did not stabilize in flight. In MPS machine gun cartridges, the seats of bullets and primers had additional sealing to keep the powder charge dry during prolonged exposure to water. 5.56 MM automatic active-action cartridges - with a steel bullet (MPS) and with a tracer bullet (MPST) had a relatively high accuracy of fire.

In the early 1970s, after the creation of machine gun cartridges, V.V. Simonov began designing a special automatic underwater system, which included the 5.66-mm underwater assault rifle AG-022. This sample was a weapon system with a rigidly locked bore, the original design elements of which were gas engine automation, ensuring the functioning of the weapon in water and air, as well as a magazine with a capacity of 26 rounds with their cut-off, operating reliably in different conditions operation. The AG-022 assault rifle had less weight and dimensions compared to the AK-74 assault rifle, despite the use of a more (one and a half times) powerful cartridge and a longer (twice) 5.56 mm cartridge compared to the 5.45 mm cartridge 7N6. The appearance of such a rifle complex, designed to combat underwater targets, had no analogues in the world and was a unique development domestic gunsmiths. These works for the first time laid the foundation for the creation of automatic small arms effective for shooting at aquatic environment.

The automation of the new weapon works on the principle of removing powder gases from the barrel. Locking is accomplished by turning the bolt. The original elements of its design are the automatic gas engine, the design of which includes an automatic gas regulator, ensuring reliable operation of the weapon both in the aquatic environment and in the air. The operation of the gas regulator uses differences in the density of media (water or air) to automatically discharge part of the powder gases when firing in air. The striker-fired firing mechanism, powered by a recoil spring and assembled in a separate assembly, allows for single and automatic fire (short bursts of 3–5 shots or long bursts of 10 shots).

Unlike most modern machines APS fires from the rear sear, i.e. with the bolt open. The reloading handle is located on the right side of the bolt frame. The safety lever, mounted on the receiver on the left above the pistol grip fire control, also serves as a fire type translator. The receiver is made from stamped sheet steel. The APS assault rifle has a smooth barrel (without rifling), since the bullets are stabilized hydrodynamically. Sights consist of a simple non-adjustable open rear sight on the receiver and a front sight mounted on gas chamber. To ensure effective shooting, the machine gun has a retractable wire shoulder rest.

The cartridges are fed from a metal magazine with a capacity of 26 cartridges, which have a special design. The unusual shape of the magazine is due to the elongated cartridge (150 mm) and relatively short length feeder springs. Inside the magazine (in the transition part) there is a vertically located limiter plate that separates the two rows of cartridges contained in it. This limiter prevents the elongated cartridges from crossing during feeding and reaching the chambering line. In addition, the design of the magazine and its receiver in the receiver contains special parts that prevent the cartridge from skewing with the bullet upward when fed into the barrel or from double feeding of cartridges into the barrel.

Sights are of the simplest design, including a non-adjustable open rear sight on the receiver and a front sight on the gas chamber. The stock is telescopic, retractable, made of steel wire.

To use the APS assault rifle on underwater vehicles, both to fight the enemy and for self-defense against sea predators, a trunnion is mounted on its barrel, through which the weapon is secured in the ball bearing of the embrasure. The APS is equipped with two magazines and accessories.

In an underwater position at a depth of 5 m, the MPS cartridge provides an effective firing range at scuba divers of up to 30 m; at a depth of 20 m, the effective range is reduced to 20 m, and at a depth of 40 m it is only 10 m. It must be taken into account that the line-of-sight range at at the indicated depths without the use of special equipment does not exceed the effective firing range of the APS, that is, if the enemy can be visually detected, then he can be hit. Therefore, underwater automatic systems are capable of solving special tasks at depths of up to 40 m from all positions, including afloat, and at all immersion depths they ensure reliable destruction divers at ranges significantly exceeding their visual visibility.

At extreme firing ranges in water, the bullet hits a swimmer dressed in a diving suit with insulation, and also pierces 5 mm thick plexiglass. The new weapon allows combat swimmers to use it for shooting not only underwater, but also on land. However, due to the fact that MPS and MPST bullets do not have dynamic stabilization sufficient for a less dense air environment, the firing accuracy turns out to be low, the effective firing range is 100 m. In addition, even taking into account the use of a gas regulator, the survivability of the underwater assault rifle when firing at air is reduced by more than 10 times - from 2000 shots under water to only 180 shots in the air.

The 5.66 MM underwater special assault rifle (APS) was adopted by the USSR Navy in 1975. APS assault rifles are used by combat swimmers from the Navy's underwater sabotage forces and assets (PDSS). Precisely with automatic machines APS and SPP-1 pistols were armed with Soviet combat swimmers who ensured the safety of the ships of the heads of two states: the USSR and the USA (M.S. Gorbachev and George Bush) during their negotiations off the coast of the island of Malta in December 1989. The production of APS assault rifles was carried out by the state enterprise Tula Arms Plant.

At the end of the 1960s, the Central Research Institute of Precision Engineering (TSNIITOCHMASH) began development of effective weapon for combat swimmers of the USSR Navy.

By the early 1970s, special ammunition for underwater firearms, using elongated non-rotating bullets with hydrodynamic stabilization using a cavitation cavity generated when the bullet moves in water. At the same time, the designers of TsNIITOCHMASH - husband and wife V.V. Simonov and E.M. Simonova developed and adopted for service with the USSR Navy a 4-barreled non-self-loading pistol SPP-1 chambered for a 4.5-mm special SPS cartridge, created by designers V. and E. Samoilov, O. Kravchenko, I. Kasyanov.

APS stock is folded

And in 1975, a weapon complex was adopted by the USSR Navy, consisting of the Submarine Special APS Automatic, also developed by the husband and wife of V.V. Simonov and E.M. Simonova, and 5.66 mm special ammunition from the Ministry of Railways.

The APS assault rifle is designed to arm combat swimmers and serves to destroy enemy combat swimmers, their underwater transporters, watercraft under water and on land.

The APS automatic machine is built on the basis of automatic equipment with a gas exhaust engine and locking by turning the bolt. The design of the gas outlet duct provides an automatic gas regulator, ensuring the operation of the automation both under water and in air. The operation of the gas regulator uses differences in the density of media (water or air) to automatically discharge part of the powder gases when firing in air. With its help, you can change the amount of exhaust gases and, accordingly, the speed of movement of the moving parts.

The barrel of the machine gun is smooth, without rifling, and the bullet does not mechanically interact with the barrel, since the bullets are stabilized hydrodynamically.

The receiver is made from stamped sheet steel.

The trigger mechanism is striker-type, providing firing with both single shots and automatic fire, driven by a single return spring of the bolt group. The fire safety switch is located on the left side of the receiver, above the pistol grip.

APS stock is folded

The charging handle is located on the right side of the bolt frame.

Sights are of the simplest design, including a non-adjustable open rear sight on the receiver and a front sight on the gas chamber.

The machine gun has a telescopic butt made of round wire, which in the stowed position is retracted inside the receiver.

The APS is fed with ammunition from attached carob (box) magazines with a capacity of 26 rounds, which have a special design that prevents the cartridges from being skewed upward when fed or from double feeding of cartridges into the barrel. The unusual shape of the magazine is explained by the fact that the feeder spring has a shorter length compared to the cartridges.

A cut-off device is placed in the receiver to prevent several rounds from being fed into the chamber at the same time.

APS with used ammunition

The MPS cartridge used in the APS assault rifle is based on the cartridge case of the Soviet standard 7N6 5.45x39 mm cartridge. The unusual caliber – 5.66 mm – has a fairly simple explanation. The machine gun's ammunition is created using a standard steel case of the 5.45 mm Soviet machine gun cartridge. 5.45 mm - caliber of rifled barrels along the fields. The diameter of 5.45 mm barrels along the rifling is 5.66 mm, the same is the nominal diameter of the leading part of the bullets of 5.45 mm machine gun cartridges. The diameter of the steel bullet of the APS machine gun corresponds to the outer diameter of the cartridge bullet of 5.45x39 mm. But since the MPS bullet does not cut into the rifling, the caliber of the APS barrel corresponds to the outer diameter of the bullet and has the corresponding designation - 5.66 mm.

The MPS cartridge bullet is a steel rod with a narrowing head in the shape of a double truncated cone. Bullet length - 120 mm, weight - 20.3-20.8 g. Initial bullet speed in air - 365 m/s. The initial speed of a bullet at a depth of 5 m is 240-250 m/s. Chuck length – 150 mm. Cartridge weight - 27-28 g. MPS cartridges have a relatively high accuracy of fire, are protected from corrosion in sea ​​water and penetration of water into the powder charge and igniter primer. The cartridge case is of a traditional design; it contains a propellant powder charge, which ejects a bullet from the barrel and activates the automatic weapon, based on the use of the energy of gases removed from the hole in the barrel wall. Stabilization of a bullet in water is carried out due to the formation of a cavitation cavity around the bullet during movement. The formation and retention of a cavitation cavity is ensured by appropriate selection of the shape and size of the bullet and its speed. The barrel of the APS assault rifle is smooth, has no rifling, and the bullet does not mechanically interact with the barrel. The bullet does not stabilize in air.

The destructive ability of the MPS cartridge bullet depends on the depth of immersion. At depths of up to 5 m, the lethal range is 30 m. At a depth of 40 m, it decreases to 10 m. In all cases, the lethal range under water exceeds the target’s visibility range - that is, if the enemy is visible, he can be hit. At a distance of more than 15 m, accuracy when firing from the APS is noticeably reduced. And, probably, this circumstance, combined with the often poor visibility under water, led to the need to include an MPST cartridge with a tracer bullet in the ammunition load, which makes it possible to adjust shooting along the routes.

The destructive power of the APS at extreme distances under water hits an enemy dressed in a “dry” wetsuit with foam padding, and also penetrates plexiglass up to 5 mm thick.

APS when used underwater

On land, the flight of a bullet-needle is not stabilized, but at a distance of 30 meters all hits fit into a circle with a diameter of 15 centimeters, the destructive power of a bullet-needle on land is maintained at a distance of up to 100 meters, but the dispersion of hits is already such that there can be no aimed shooting and speeches. In addition, even taking into account the use of a gas regulator, the service life of the machine gun when firing in the air is reduced by more than 10 times - from 2000 shots under water to only 180 shots in the air.

Underwater rifle machine APS is a unique development that marked the beginning of the development of a new (aquatic) environment for the use of self-cocking and automatic firearms in it.

The production of APS in limited quantities was established at the Tula Arms Plant, and was even offered for export through RosOboronExport.

This machine gun was developed specifically for naval special forces. It can shoot both on land and underwater. He becomes menacing when necessary assault weapon or a tool of silent sniper warfare. The designers managed to incorporate the potential of an entire arsenal of weapons into one sample. Until recently, it was classified and showing it in public was strictly prohibited. Today the secrecy has been lifted and we can take a closer look new development Tula K.B. instrument engineering called ADS - double-medium special automatic machine.

Konstantin Lazarev

Very little is known about combat swimmers. Water is one of the most difficult environments for human survival, and not everyone can feel normal in it, much less work. This is the lot of real professionals. True, you should not think that combat swimmers are exclusively “aquatic inhabitants”. Of course, water is only one of the media in which they work, and a large number of operations take place on land, far from any bodies of water. This is the age-old problem of arming naval special forces: fighters need weapons to work both under water and on land.

In the 70s of the twentieth century, special forces units of the Soviet navy were armed with two types of special underwater weapons. These are the SPP-1M pistol of 4.5 mm caliber and the APS assault rifle of 5.66 mm caliber. By the way, the latter still has no analogues in the world. The USSR is the only country where automatic firearms underwater weapons were created.

Both the pistol and the machine gun show decent shooting results in water, hitting the enemy at distances exceeding the diver’s line of sight. Their highlight is SPS and MPS ammunition. The bottle-shaped case contains a long needle-shaped bullet 120 mm long, which comes out of a smooth barrel without rifling. When moving, such a bullet creates a cavitation cavity in front of itself - a cavity filled with water vapor. Cavitation stabilizes the needle bullet and helps it move faster. Needle bullets retain lethal force at distances of up to 30 m, while conventional rifled cartridges are powerless already at a meter distance.

The SPP-1M and APS underwater weapons were initially developed for firing underwater, but later it turned out that their ammunition can also hit targets on land. The APS underwater assault rifle allows effective shooting on land at distances of up to 100 m, the SPP-1M underwater pistol - at a distance of up to 17 m. For close combat this is quite enough, but if we're talking about about working over longer distances on land, naval special forces soldiers have to take with them not only underwater weapons, but also land ones. In this case, the list of weapons for a combat swimmer looks like this: an AKS assault rifle with a folding stock, underbarrel grenade launcher 6G15 and underwater assault rifle special APS. Such a set itself weighs a lot, and in addition, the weight of the portable ammunition increases: after all, APS and Kalashnikov use different ammunition, and you have to take both with you.

Double-medium special automatic (ADS). Weight - 4.6 kg; length - 660 mm; barrel length - 415 mm; rate of fire - 600−800 rounds per minute; sighting range— 600 m on land, 25 m in water.

In order to reduce the weight of wearable weapons and ammunition, the Navy command developed technical task for a fundamentally new universal double-medium assault rifle that could combine an AK, an APS and a grenade launcher and at the same time be no worse than each of them separately both in the aquatic environment and on land. The task of developing such weapons was assigned to the Tula Instrument Engineering Design Bureau.

Barrel from the shoulder

Double-medium special automatic gun ADS is a weapon with a gas exhaust system, in which the barrel bore is locked by turning the bolt. The basis was taken as the A-91 assault rifle, a universal assault rifle-grenade launcher complex created at the Tula Instrument Design Bureau, combining a 5.45 or 5.56 mm caliber assault rifle and an integrated 40-mm underbarrel grenade launcher. Significant changes were made to the basic machine - the operation scheme of the automation, coating materials and some other elements were changed. And although the machines were very similar in appearance, technically the ADS was quite different from its progenitor.

APS (underwater special automatic machine). In service since 1975; weight - 2.46 kg; length - 832 mm (with the butt unfolded; rate of fire - 500-600 rounds per minute; sighting range - 30 m (at a depth of 5 m), 100 m on land.

As a form factor for a double-medium machine gun, a bullpup design was chosen, in which the magazine is placed behind the handle, and the receiver simultaneously serves as a butt. This arrangement significantly reduces the overall length of the weapon while maintaining the required barrel length and, as a consequence, the firing distance. The advantages of this arrangement are obvious. A shorter weapon length implies a smaller projection, that is, the shooter is presented with a smaller target. The bullpup system greatly simplifies the work with weapons in enclosed spaces, narrow rooms and when entering a doorway or window.

The bullpup has not become as widespread as weapon systems with a traditional magazine and grip arrangement due to some “chronic diseases” of the design, including difficulties when shooting from the left shoulder (cases fly straight into the shooter’s face) and a center of gravity shifted to the rear part of the weapon. The problem of the center of gravity disappeared when it was decided to introduce an integrated grenade launcher into the design, which balanced the heavy rear part of the weapon.

SPP-1 (special underwater pistol). In service since 1971; weight - 950 g; length - 244 mm; Magazine capacity - 4 rounds, loaded into separate barrels.

With the ejection of cartridges to the right and side and inconvenience for a left-hander, the situation was a little more complicated, but a solution was found here too. Firstly, to make it easier for the shooter to work with the ADS with any dominant hand, the reloading handle was made rotatable so that the shooter could choose where it was more convenient for him to reload the weapon. Secondly, the designers developed a system in which spent cartridge case it is extracted not to the side, but forward, and thus does not touch the shooter’s face, no matter which side of the machine gun it is on. The cartridge case flies out of a small hole located at the base of the handle for carrying the weapon.

Thanks to this fact, as well as the bolt, made in the form of a piston that fits tightly into the receiver, there are no large holes on the ADS body. As a result, the level of gas contamination in the area of ​​the shooter's face is reduced (which is especially important for aiming under water), in addition, the risk of dirt getting inside the receiver is reduced, which has a positive effect on the reliability of the machine gun.

Cartridge with a secret

Creating ammunition for the ADF is a task at least as important and complex as developing the machine gun itself. The designers had to produce a cartridge for underwater shooting with dimensions and caliber similar to those of the standard “land” 5.45 x 39 mm cartridge, but not inferior in range to the “underwater” MPS cartridge.

Tula gunsmiths coped with this task: the new PSP cartridge ensures destruction of underwater targets at distances of up to 25 m, while allowing targeted fire on land at 100 m or more. The progress achieved was made possible thanks to the use of a bullet of increased length (compared to the Kalashnikov bullet), which is recessed more deeply into the cartridge case, which allows maintaining the dimensions of a standard intermediate cartridge. The bullet works on the same principle as its predecessors: when fired, it creates a cavitation cavity in front of itself, which helps the projectile maintain stability and speed in an aquatic environment longer.

To fire underwater cartridges, you just need to change the ammunition and set the gas regulator of the machine to the underwater position. However, in extreme situation, if the diver suddenly has a need to immediately engage in combat on land, he can shoot without even changing the position of the gas regulator and without replacing the cartridges with “regular” ones. Of course, the results may not be the same as when shooting from a standard AK, but this will be quite enough to repel a surprise attack.

The new PSP cartridge has a lot of advantages. Being identical in dimensions to the standard 5.45 x 39, this cartridge is unified with it, which means that the ADS can fire both PSP and standard AK cartridges, while delivering shooting results consistent with the standard AK74. If it is necessary to work both on land and under water, the operative takes with him two types of cartridges and only ONE machine gun. There is no need to carry additional magazines for underwater cartridges, because PSP cartridges can be loaded into standard AK magazines (although to ensure trouble-free operation underwater, magazines for underwater cartridges have a different feeder spring).

The built-in grenade launcher counterbalances the heavy rear of the rifle, eliminating the typical bullpup problem with a shifted center of gravity.

All this means that the combat swimmer will carry much less weight. And if suddenly the ammunition runs out on the battlefield, he will be able to replenish the ammunition with standard AK cartridges at any warehouse or even use the ammunition of a defeated enemy: after all, most armies of the world have Kalashnikovs.

Swim light

The Tula ADS is a multi-tasking weapon, practically a transformer. One machine gun can be used as an arsenal of several weapons at once. In addition to the machine gun itself, which can fire on land and under water, the weapon complex includes a 40-mm grenade launcher that fires VOG-25 grenades. This ammunition is capable of hitting the enemy at distances of up to 400 m. Once it hits the target, the grenade hits everything around with fragments within a radius of 10 m. Such an explosion in an open space can greatly thin out the enemy’s ranks, and even in an enclosed space it will completely destroy all living things. Despite the fact that the grenade launcher is integrated into the ADS body, its barrel and sight can be removed if necessary to reduce the weight of the weapon.

The machine gun has two triggers inside the contour of the trigger guard. One is responsible for firing from the machine gun itself, the other is responsible for the grenade launcher. It is noteworthy that the trigger of the machine gun has a safety device in the form of a key on the hook, which the shooter must fully press before firing a shot. Similar technical solutions They are extremely rarely used on long-barreled weapons and are more typical for pistols, such as the domestic SR-1 or the Austrian Glock. They provide more than high level safety when handling weapons.

In addition to the basic options, the machine gun also has additional ones: it can be equipped with a removable silent firing device, which significantly reduces the sound of the shot. Using it, ADS can be used in reconnaissance missions or for the covert destruction of sentries in the event of an assault. A Picatinny rail is mounted on the handle for carrying weapons, on which you can install any optical daytime or night sight or collimator. In this case, the ADS turns into a sniper rifle. One of the solutions in the design of the ADS completely introduces it into the hall of fame of spy gadgets. When firing single shots, the cartridge case does not leave the receiver of the weapon and remains in a small hole through which it is usually extracted outward. With the next shots, the previous cartridges will be pushed out by the subsequent ones. But if necessary, you can hit the target with a single shot and leave no traces.

To date, the double-medium special ADS automatic machine has already passed all stages military tests and officially adopted Russian army. This weapon belongs to the special category, and will be armed primarily with special forces units and, first of all, with naval units. ADS has also been adopted by a number of security forces that ensure security in water transport and water areas.
