Until 2005, unitary VOG-17 and VOG-ZO rounds with high-explosive fragmentation grenades were used to fire from 30-mm mounted anti-personnel grenade launchers AGS-17 and AGS-30 (Fig. 1, Fig. 2).
In the first VOG-17 grenade launcher round developed by FSUE SNPP Basalt, the grenade consists of a turned thin-walled body, inside of which there is a fragmentation jacket in the form of a twisted and transversely notched steel spring square section, as well as two explosives. By virtue of design features When the hull is detonated, many small fragments are formed, which make it possible to effectively hit unprotected manpower.
In the second generation VOG-ZO round, created by the Federal State Unitary Enterprise FSPC Pribor, the grenade body is made by cold deformation with the formation of semi-finished rectangular-shaped striking elements on the inner surface of the mesh. The use of a new housing design made it possible to press the explosive directly into the housing and thereby increase the filling factor by 1.1 times. Taken together, this ensured an increase in the effectiveness of fragmentation damage by more than 1.5 times.
VOG-17 and VOG-ZO rounds are equipped with a head mechanical fuse instant action, semi-safety type, with a pyrotechnic mechanism for long-range arming and self-destruction.
There are three modifications of grenade launcher rounds. The original and already obsolete type VOG-17 with an instantaneous fuse. The subsequent modification, VOG-17M, differs from the previous one in that the fuse is equipped with a self-destruct device. The self-destruct mechanism is activated by overloads when fired. Fuses of all types of grenades are cocked at a distance of 10-60 m from the muzzle of the grenade launcher, which provides additional safety when firing. For training shooting, practical VUS-17 rounds are used, equipped with a pyrotechnic composition of orange smoke, indicating the location of the grenade landing. The grenades of these shots are equipped with a copper leading belt pressed into the grenade body.
These shots meet strict Russian standards in all respects and are mass-produced. Despite the smaller caliber compared to some foreign grenades, the striking effectiveness of these shots is even higher (Fig. 3).
However, the maximum firing range of the AGS-17 and AGS-30 grenade launcher systems using VOG-17 and VOG-ZO rounds is 1730 m, which is significantly less than that of foreign grenade launcher systems.
In addition, over time, experts also began to note the insufficiently high fragmentation efficiency of VOG-17 and VOG-ZO ammunition when fighting manpower protected by constantly improving personal armor protection, as well as their large technical dispersion over range, amounting to Vd/Xmax ≤ 1 /70.
These shortcomings reduced the technical level of Russian grenade launcher systems, and consequently their competitiveness in the international arms market. Due to these circumstances, the question of improving the basic tactical and technical characteristics VOG-17 and VOG-ZO rounds at the end of 1999 became extremely relevant and required urgent decisions. A study of the design of the VOG-17 and VOG-ZO rounds showed that their combat capabilities within the framework of existing designs have largely been exhausted. It became obvious that it was possible to increase the firing capabilities of grenade launchers and expand the range of tasks with their use through the development and adoption of more powerful multi-purpose high-explosive fragmentation ammunition.
Based on the trend of global development of ammunition and conditions modern combat, according to military experts, for these complexes it was necessary:
Increasing the maximum firing range from 1730 m to at least 2100 m;
Improved combat accuracy Vd/Xmax from 1/70 to 1/100;
An increase, in comparison with a standard VOG-ZO shot, is ≈ 1.3 times the area of fragmentation destruction of unprotected manpower, as well as manpower in body armor with a specific penetration energy of 62 kg/cm2.
Due to these circumstances, in 1999, the State Unitary Enterprise "Instrument Engineering Design Bureau" began work on creating a new 30-mm GPD-30 round with a high-explosive fragmentation grenade of increased efficiency for the AGS-17 and AGS-30 grenade launchers in service.
It was obvious that it was not possible to significantly increase the maximum firing range in the traditional way, that is, by increasing the lateral load of the grenade and its initial speed, since standard grenade launchers are designed for a certain recoil impulse.
The existing experience in solving such issues clearly indicated that it is possible to increase the firing range while maintaining recoil momentum only by improving the aerodynamic shape of the grenade. Achieving better performance in terms of combat accuracy is possible only by increasing the accuracy of guiding a grenade along the barrel, reducing the spread of its initial speed, ballistic coefficient and center of mass imbalance, which together allows the grenade to leave the barrel with minimal disturbance and more accurately reach the intended target.
The task of increasing the lethality of the grenade turned out to be no less difficult.
The task of increasing the area of fragmentation destruction of manpower, including those protected by body armor, was solved in a comprehensive manner, namely, by optimizing the average mass of fragments, increasing their speed and angles of expansion, and using grenades in more and with a stronger high-explosive effect of the explosive.
Worked out for a new shot new way making a grenade body. In this case, it is manufactured, like the body of the VOG-ZO grenade, by the method of volumetric deformation on its inner surface of a fragmentation mesh of a rhombic profile, in which all sides of an individual fragmentation element are oriented relative to the texture of the cold-worked body at a certain angle. It was the absence of longitudinal stress concentrators in the fragmentation network that excluded the destruction of the hull along its generatrix, and, consequently, the formation of large and “saber-shaped” fragments, which reduced the utilization rate of the hull metal.
The uniqueness of the noted technology lies in the fact that it allows only two operations and without relative axial displacement of the forming tool and the body blank to completely produce a fragmentation mesh. This ensures high durability of the tool and lasts for long time the initial accuracy of the geometry of the riffles, responsible for the destruction of the hull in strict accordance with the number of semi-finished elements embedded in the fragmentation mesh.
The end result of the work done was the adoption in 2005 of the Ministry of Internal Affairs of the Russian Federation of a modern 30-mm grenade launcher with a high-explosive fragmentation grenade of increased efficiency (Fig. 4, Fig. 5).
The grenade launcher device is shown in Figure 6.

Rice. 6. Design of the GPD-30 grenade |
The shot works as follows.
When the primer is initiated, the propellant charge located in the bottom recess is ignited. The resulting powder gases flow through transverse channels into the external cavity, thereby equalizing the pressure on both sides of the wall of the hollow stern. Taking into account the fact that the end part of the stern is limited by the bottom side surface of the liner, the volume of the external cavity is significantly less than the volume of the charging chamber, and the flow area of the transverse channels has a very definite value, the increase in pressure in both volumes occurs almost simultaneously and without residual deformation of the stern wall.
After the powder gases reach the so-called forcing pressure, the grenade is pressed initially by its leading belt into the bullet entrance, and then into the side edge of the rifling of the barrel bore, forming leading protrusions on the belt in a shape that corresponds to the rifling of the barrel bore. The belt material displaced by the rifling field is freely placed in the depressions of the comb belt, thereby providing the necessary condition for the grenade to fly out of the barrel with minimal disturbances, and therefore the possibility of providing a greater firing range. When the grenade reaches the muzzle of the barrel, it leaves the latter with a given linear and angular velocity. In flight, a rotating grenade captures air with its intake planes 16 of its transverse grooves 10 and thus creates additional resistance forces at its end, causing the appearance of a lifting force and an additional stabilizing pitch moment relative to the center of mass of the grenade located upstream of the air flow. As a result of this, the nutational vibrations of the grenade are damped, thereby reducing its drag, which helps to increase the flight range.
When the grenade reaches the target, the sharp deceleration triggers the head fuse 17, causing the detonation of the explosive 18 and, as a consequence, the destruction of the grenade body and the formation of a high-speed flow of damaging elements.
Rationality distinctive features The performance of the third generation GPD-30 shot in comparison with the second generation VOG-ZO shot is confirmed by the graphical dependencies shown in Figures 7-12.
A comparative analysis of the presented graphs shows that the use of the GPD-30 round instead of the VOG-ZO round allows:
Increase the maximum firing range by 21.4% by reducing the drop in speed during flight;
Increase the altitude by 16% when firing flat and mounted trajectories;
Reduce the sensitivity of the grenade trajectory to the action of side winds by 1.5-2 times both during flat and mounted shooting;
Reduce the sensitivity of the firing range to the action of longitudinal wind by 1.5-2 times when firing at throwing angles of up to 40°.
At the same time, the flight time of the grenade is reduced by up to 40% during flat firing at a distance of up to 1730 m and increases slightly during mounted firing due to an increase in the trajectory height.
Appearance fragments distributed among mass groups is presented in Figure 13 and indicates the planned fragmentation of the grenade shell.
To numerically assess the superiority of the GPD-30 grenade over the VOG-ZO grenade, the reduced area of fragmentation damage within their maximum firing range was calculated.
The results of calculating the reduced area of damage by fragments of a given fragmentation of GPD-30 and VOG-ZO grenades depending on the firing range (the angle of approach of the grenade to the target) are shown in Figure 15.
As you can see, in terms of the area of the reduced fragmentation damage of the GPD-30 grenade, in the entire range of firing ranges it significantly exceeds the standard VOG-ZO grenade.
Based on experimental data assessing the maximum firing range, combat accuracy and reduced area of fragmentation damage of GPD-30 and VOG-ZO rounds, as well as calculating the effectiveness of their combat use, the superiority of the new development in all main and auxiliary parameters is shown (Fig. 16).
The high level of technical and economic indicators of the GPD-30 shot allowed the State Unitary Enterprise "Design Bureau of Instrument Making" to organize it mass production V as soon as possible and at minimal cost. Since 2005, the GPD-30 round has been exported.
The 40-mm VOG-25 (7P17) shot is unitary in design and is made according to a “caseless” design, i.e. The propellant charge together with the ignition agent is located in the bottom part of the grenade body. This is the first time such a shot pattern has been used in domestic practice. It made it possible to greatly simplify the design of the grenade launcher and, accordingly, increase the reliability of the weapon, coupled with an increase in the combat rate of fire. The shot grenade is a fragmentation grenade with a steel body. Inside the grenade body (between the bursting charge and the body) there is a cardboard mesh for rational crushing of the body into fragments, which helps to increase the fragmentation effect. Here it is simply necessary to note that the VOG-25 round grenade is 1.5 times more powerful at the target than the 30-mm OFZ round for the 2A42 cannon, which is equipped with the BMP-2.
The outside of the grenade body has ready-made rifling, which serves to give the grenade a rotational movement (the grenade is stabilized in flight due to rotation) as it moves along the barrel. The grenade fuse (index VMG-K) is a head, impact, instantaneous and inertial action, semi-safety type with pyrotechnic long-range cocking and self-liquidator. The cocking distance is from 10 to 40 meters from the muzzle of the grenade launcher. Such a significant spread is due to the temperature range of use of the weapon (from minus 40°C to 50°C). The response time of the self-destruction mechanism is 14–19 seconds.
In 1978, comparative tests of the GP-25 grenade launcher with the VOG-25 round and the 40-mm M-203 under-barrel grenade launcher mounted on the M16A1 rifle with the M-406 round were carried out. Tests have shown a significant advantage of the domestic grenade launcher and its shot over a similar system produced in the USA. The VOG-25 and M-406 shots were compared by firing at an area where a target environment was located, simulating openly located manpower (lying growth targets). During these tests, it was revealed that the frequency of hitting targets on the tactical field from the explosion of a grenade from a VOG-25 shot is 3–4 times higher than from the explosion of a fragmentation grenade from an M-406 shot. 
While the designers from TsKIB SOO were designing the GP-25 grenade launcher, namely in 1974, their colleagues from the Pribor State Research and Production Enterprise were given a new task. It was necessary to develop a new 40-mm shot for an under-barrel grenade launcher with increased fragmentation efficiency against manpower lying down and in unprotected shelters from above (trenches, trenches, stones, etc.), compared to the VOG-25 shot grenade, 1 .5–2 times (without reducing the effectiveness of fragmentation against growth targets). This, frankly speaking, difficult technical problem was brilliantly solved by the team of designers from the Pribor State Research and Production Enterprise. In 1979, a new 40-mm shot with the VOG-25P fragmentation grenade was presented for field testing (
“Foundling”, index 7P24) and in the same year the new shot was recommended for service with the SA. The main and main difference of the new shot was the head fuse, which received the VMG-P index.
An expelling charge and a pyrotechnic moderator were introduced into the design of the VMG-P fuse, ensuring that the grenade “bounces” after hitting the ground and explodes in the air when fired at all combat ranges of the grenade launcher. The height of the grenade burst when fired at medium-hard soil was 0.75 m, which made it possible to increase the effectiveness of the fragmentation action in comparison with the VOG-25 shot grenade.

Giving the grenade a rotational movement while moving along the barrel. The shot is made according to a “caseless” design; the propellant charge of P-200 pyroxylin powder, together with the ignition agent, is located in the bottom part of the grenade body. This design made it possible to simplify the design of the grenade launcher, increase reliability and combat rate of fire. Inside the housing (between the explosive charge and the housing) there is a cardboard mesh. It serves to rationally crush the body into fragments, which leads to an increase in the fragmentation effect.

General device
The GP-25 is mounted under the barrel of the machine gun. It consists of 3 main parts:
- barrel with sighting device and bracket for attaching to a machine gun
- breech
- trigger housing with handle
The grenade launcher kit includes:
- butt plate with belt
- return spring guide rod with latch
- grenade launcher bag
- shot bag
- banner
- cleaning rod (cleaning device)
With the GP-25 attached, the machine gunner, depending on the task at hand, can fire from both a grenade launcher and a machine gun.
Firing is carried out by direct and indirect fire (flat and mounted trajectory).
To alleviate the recoil force, which when firing from a grenade launcher is slightly greater than when firing from a machine gun, a special rubber butt pad is installed on the butt of the machine gun.
Purpose of the main parts and mechanisms of the grenade launcher
Trunk The grenade launcher serves to direct the flight of the grenade, has 12 rifling, curling from left to top to right, serving to give the grenade a rotational movement during flight, which ensures its stability along the trajectory.
bracket designed for attaching a grenade launcher to a machine gun and placing sighting devices. The front and rear supports of the bracket have seats for mounting a grenade launcher on a machine gun.
Aim serves to aim the weapon at the target when firing from a grenade launcher.
There is a distance scale on the bracket on the left under the sight.
Distance scale: first group of numbers ( white) from 1 to 4 is intended for installing sights when firing direct fire (flat trajectory). Intermediate divisions correspond to firing ranges of 150, 250 and 350 m.
The second group of numbers (red) is intended for semi-direct fire (overhead trajectory).
At direct fire(for shooting with a flat or mounted trajectory), aiming is carried out using one guide aiming line passing through the middle of the rear sight slot, the top of the front sight to the aiming point.
At semi-direct aiming(for shooting with a mounted trajectory) aiming is carried out separately:
- in the horizontal plane, aiming is carried out at the front sight so that it is on target
- in a vertical plane along a plumb line - the machine is given such an angle that the mark on the plumb line coincides with the mark (11) on the stopper sleeve
The plumb line serves to give the grenade launcher the necessary elevation angles when firing with indirect fire (overhead trajectory) at unobserved targets located on reverse slopes, terrain folds or in open trenches and trenches. It is installed on the sight axis using a plumb bob bushing and a stopper bushing.
The sight spring presses the plumb bob bushing against the closing protrusions of the sight axis and thus secures the sight in assembled form.
The sight stopper ensures that the sight cannot be reset at the moment of firing; the stopper spring holds it in the upper position.
Breech: is a camera high pressure, in which the grenade propellant charge burns.
Trigger housing with handle connects to the breech and together with it represents a part of the grenade launcher, separated from the barrel with a bracket when the grenade launcher is placed in a carrying bag. The housing houses the trigger mechanism.
Lever serves to hold the grenade launcher when firing; it is connected to the body by means of an elastic lock.
Frame The housing covers the forend of the machine gun and protects it from mechanical damage when firing. An elastic insert is glued into the body frame, which serves to prevent hard impacts on the receiver of the machine gun when firing from a grenade launcher.
Shock trigger mechanism serves to fire a shot from a grenade launcher.
It consists of:
- trigger with striker
- release with spring and rod
- pusher
- mainspring
- oppression
Translator when set to the “PR” position (the lever is in a vertical position), it locks the trigger, protecting the loaded grenade launcher from an accidental shot. Before firing a shot, the translator should set the lever in a horizontal position to the “OG” position), thereby releasing the trigger.
Butt pad serves to soften the recoil force when firing from a grenade launcher when the butt of the machine gun is resting on the shoulder of the shooter and to prevent deformation of the butt of the machine gun when firing with the butt resting on hard ground.
The procedure for partial disassembly and assembly of a grenade launcher
Disassembly of a grenade launcher can be incomplete or complete.
Partial disassembly is performed during routine maintenance.
Complete disassembly is carried out during maintenance, for cleaning in case of severe contamination, after the grenade launcher is exposed to rain or snow, and during repairs.
The grenade launcher is disassembled and assembled on a table or clean mat (tarpaulin). Place parts and mechanisms in the order of disassembly, handle them carefully, do not place one part on top of another, do not allow them to hit hard objects or each other, and do not use excessive force during disassembly and assembly.
The procedure for incomplete disassembly of a grenade launcher:
Reassembly after partial disassembly is carried out in the reverse order:
- attach the breech to the trigger body
- insert the housing axis and translator into their holes
- attach a check
- attach the barrel to the trigger body
- put the translator in the "PR" position
Shot device VOG-25, VOG-25P and “Nail”
VOG-25 fragmentation rounds and VOG-25p fragmentation and bouncing rounds are designed to destroy enemy personnel and fire crews with fragments.
A shot with a “Nail” grenade is designed to create a gas cloud with an intolerable-permissible concentration of an irritating substance; it is used both in a combat situation and during special operations.
Shot VOG-25
Shot VOG-25P
Unlike the VOG-25 shot, the VOG-25P shot device has an expelling powder charge (3), which, when the grenade meets an obstacle (ground), by the force of the resulting pressure, breaks the connecting thread (12), pushes the fragmentation jacket of the grenade with the explosive charge to a height up to 1.5 m, where its detonation occurs, due to this the effectiveness of hitting the enemy with fragments significantly increases.
