35 mm Oerlikon Contraves AHEAD programmable shells

One way to increase the likelihood of hitting a ground or air target is to use the so-called. programmable shells. Such ammunition is detonated at a given point on the trajectory - closest to the target and sends the maximum possible number of striking elements to it. One of the first developments in this class was the AHEAD projectile family developed by the Swiss company Oerlikon Contraves.

Promising solutions

Oerlikon-Contraves has for a long time been developing artillery systems for various purposes. In recent decades, new requirements for guns have appeared, and the Swiss company has responded to them by developing promising projects.

Back in the nineties, work began on the subject of programmable munitions ammunition. In the next decade, new products went to landfills and exhibitions. The ammunition family has received the designation AHEAD (Advanced Hit Efficiency And Destruction - "Increased efficiency of penetration and defeat"). To date, such products managed to enter the arsenal of a number of countries.

The AHEAD project proposed to increase the efficiency of shooting through the use of a whole artillery complex. It included the actual projectile with special capabilities, a modified gun with the necessary devices and fire control devices. Subsequently, the LMS and equipment for the guns was adapted for the possibility of mounting on different artillery systems, including different calibers.

Such a modular approach provided the AHEAD complex with well-known advantages. An artillery system of this kind can be built on the basis of different guns of all compatible calibers and used on different media. AHEAD shells have already been successfully implemented on a mass of land systems, including on military vehicles, as well as on ships.

Gun devices

To use AHEAD ammunition, the gun must be supplemented with several special instruments. The most noticeable of them is the muzzle device-programmer. It is a muzzle brake, complemented by a large cylindrical block with electronic equipment. Installation of the device is carried out directly on the muzzle of the barrel; the cable is connected to the OMS.

Inside the durable casing, in its rear and middle parts, there are two induction coils necessary for measuring the initial velocity of the projectile. In front of them is a larger coil of the programmer. These devices are used sequentially and solve different problems.

At the time of the shot, the projectile sequentially passes through two coils of the speed meter. The MSA determines the velocity of the projectile, makes corrections to the data for firing, and provides the necessary signal to the coil-programmer. She enters data into a special projectile fuse.

Programmable shells

The AHEAD ammunition family is built around common ideas and some unified components. Combining the latter with the necessary devices and products, you can create an artillery shot of the required appearance. Thanks to this, three types of shots for 35-mm guns have already been developed. It is also possible to create similar products in caliber 30 and 40 mm.

AHEAD shells of all types have a similar architecture. The conical fairing is screwed onto a cylindrical housing accommodating military equipment. A programmable fuse is located in the tail housing of the housing. The entire assembly is placed in the barrel of the cartridge case. The design and dimensions of the hull elements, as well as the combat load, depend on the caliber and type of shot. All versions use a standardized fuse.

A receiving coil and a special energy source that is triggered by a shock during firing are placed in the fuse case. Next to them is a programmable temporary device that receives data from the programmer and determines the duration of the flight. After a predetermined time, this device activates an electric fuse and undermines the charge of the projectile. AHEAD fuse works only at the set time - there is no contact mode.

For the safety of gunners, the AHEAD product has two levels of protection. The first is performed mechanically: before the movement along the barrel, the fuse contacts are open, and it remains inoperative. The electronic fuse does not allow you to set a flight time of less than 64 ms, which corresponds to the range of 60-70 m. If the data is entered incorrectly after 8 seconds after the shot, the self-destroyer is activated.

An interesting feature of AHEAD is the minimum necessary military equipment. All shells of this type have a separable housing containing ready-made striking elements. Due to this, it was possible to minimize the bursting charge, ensuring the dispersion of the GGE.

Three ammunition

The possibility of detonation at a given point on the trajectory gives shells known advantages. They can be used to more effectively hit ground or surface targets. Also increases the efficiency of firing at air targets. For use on different artillery systems for various purposes, they initially created three types of 35X228 mm rounds with shells of the AHEAD family.

The first sample of the family is designated as PMD062. It has dimensions at the level of "ordinary" ammunition of the same caliber and weighs 750 g. The central part of the hull has separable walls. When the fuse is triggered, it opens into six "petals" that provide the output of the GGE. The projectile holds 152 cylindrical GGEs laid in 8 longitudinal columns of 19 pieces each. The total mass of the elements is 500 g. The opening of the body and the release of the GGE are carried out due to the explosive charge weighing only 0,9 g.

The PMD330 projectile has a similar design, but it uses a different set of GGEs. In its central compartment, 407 striking elements are placed - 11 columns of 37 units each. The weight of the HPE has been reduced to 1,24 g.

The course to reduce GGE continued in the PMD375 project. This projectile is equipped with an 860 GGE of 0,64 g weight and has the same detonation controls and charge for ejection.

The normal muzzle velocity for AHEAD shells is 1050 m / s. The muzzle device and the OMS automatically measure the real value of this parameter and make corrections to the input data. After fuse triggering, the GGEs fly apart in the front conical sector up to 15 ° wide. A projectile with a sharp fairing can also cause some damage to the target.

The heaviest GGE projectile PMD062 can effectively hit lightly armored and unprotected vehicles, aircraft and aviation means of destruction. Lightweight GGEs from PMD330 are designed to combat manpower and unprotected equipment. The PMD375 projectile is designed to destroy small-sized air targets, including UAV.

Feature of application

AHEAD shells are suggested for use in different situations and against different purposes. In all cases, the defeat is provided by a cloud of high-speed HPE with a high breakdown effect. The ability to select a detonation point gives the artillery system operator special capabilities.

The easiest way to use AHEAD is to shoot at a certain distance in front of the target. In this case, the target falls into the cone of the expansion of the GGE and receives maximum damage. Blasting multiple shells at one point can enhance the impact or likelihood of damage. This method of application is suitable for the destruction of ground and air targets.

A shooting technique called “Pearl String” is proposed. In this case, several shots are fired with the installation of fuses at different ranges. Shells are detonated almost simultaneously and form a kind of "thread". This can be used if it is impossible to measure the exact distance to the target, to hit the columns on the track or trenches when firing from the flank.

If necessary, AHEAD shells can be used not only as fragmentation, but also as kinetic. The design of the ammunition allows punching brick and concrete walls, as well as metal, including armored barriers. For such a projectile use, it is sufficient not to program the fuse.

Wide use

The AHEAD projectile family was created under the 35-mm guns of the Oerlikon brand and their derivatives. Together with new features, this fact had a positive effect on the commercial prospects of the development. New types of shells entered service with several states. They are used with air defense artillery, as well as in the armament of armored combat vehicles and ships.

Based on the 35 mm AHEAD shells, new ammunition has been developed. First of all, unified shells appeared in the caliber 30 and 40 mm. Some of them have already found application in real projects of armored vehicles. It also offers integration of a programmable fuse into the design of the 40-mm shot for an automatic grenade launcher.

The Oerlikon Contraves AHEAD product line was one of the first of its kind, which allowed them to gain a foothold in the market. Even with foreign competitors, such ammunition retains its position and is not yet ready to give in to anyone. Moreover, the development company is doing everything possible to expand the range of shots to the wishes of various customers. It is likely that in the near future the basic 35-mm AHEAD products will become the basis for new types of artillery shots.

Programmable projectiles with such accuracy of tungsten shrapnel = a northern fur-bearing animal for unarmored targets in range. And the armored ones after such a "hail" will have to "feel" to act. Either suppress the aiming, or make part of the sighting devices on the principle of "toad's eye" diving under the armor.

Not everything is as chocolate as you said. To begin with, only reconnaissance drones and plywood homemade are not armored. The most unpleasant targets, such as anti-radar missiles, ammunition barrage and long-range shock ATGMs (not to mention anti-ship missiles), they are usually armored. And stopping a fool weighing 50-100-300 kg with shrapnel elements weighing 0.6-3 grams is unlikely.

(Although the Jews have faked their "iron dome", they did not stint) But this system is of little use for real combat purposes. You need a direct kinetic defeat of the target or at least, as the same Jews came up with, a close high-explosive gap.

That's the ambush that from afar, the gun does not hit. And on the last, 100-200 meters, it starts to hit but does not have time to destroy the target properly.

By the way, Americans faced this problem in WWII. When repelling the kamikaze attacks, they found that a lot of 20 mm guns, despite even a bunch of hits, could not stop an aircraft projectile flying aboard an aircraft carrier. Flies (albeit in pieces) and explodes.

This is just the beginning of the application of such technology - what prevents to increase the size, the affected area and the penetrating power? And with an increase in size, it is possible to penetrate inside not even a few tens of pieces of metal, but 3-5 powerful submodules with their own engines and their own navigation and with charges of ~ 5 ... 10 kg of trot. eq. each specifically for hitting "armored targets".

The NBS C-RAM system must detect, track and shoot down incoming projectiles before they can reach their target within very close range. The system itself is based on the Oerlikon Contraves anti-aircraft missile system with an air shield. The NBS C-RAM system consists of six 35mm automatic cannons (capable of firing 1000 rounds per minute), a ground control unit and two sensor units. The entire system is fully automated. The cannons fire forward-programmable ammunition developed by Rheinmetall Weapons and Amunitions-Switzerland (formerly Oerlikon Contraves Pyrotec). The ammunition carries a payload of 152 tungsten elements weighing 3,3 grams each.

[sen]

We act on a different principle. The projectile receives an optical receiver for receiving control laser signals. The fuse does not have the ability to independently determine the flight range, for which the SLA of the combat vehicle does this. When the projectile reaches the desired point on the laser channel is a command to detonate. And it seems that the fragments are scattered in all directions, not like in AHEAD, directionally.

I read the link about the features of the implementation, thanks. And about the expansion, where did you get this? Immediately what kind of thing, the shell itself is flying forward, that is, the linear speed of the fragments is already reported. Give them an expansion speed and you will inevitably get a distribution cone. Oerlikon puts a kick charge behind the elements and pushes them forward. And ours put a charge in front of them and push back?
Even if you just put a charge in the form of a ball in a mound of fractions, you will still get a cone. But, as far as I know, ours haven’t been doing this for so long, ours are engaged in packing GPEs no less than Erlikon. And it’s not rational: the smaller the distance from the pickup sensor (and it is most likely at the bottom of the projectile) to the detonator, the better.

[sen]

No, ours has a charge in the middle, while AHEAD has a rear cone, respectively, and the cone of expansion of fragments in ours will be larger.

No not like this. As I understand it, the team is exactly the same as Erlikon, they set the gap immediately after the shot. But instead of using an electromagnetic coil on the barrel, they use a laser beam near the barrel and an optical receiver in the bottom of the projectile. This works immediately after the shot, the laser measures the speed of the flying projectile and after it throws the burst timer.

[riwas]

Misunderstood. Quote from the article:
https://topwar.ru/158074-snarjady-s-upravljaemym-podryvom-na-puti-v-vojska.html

From the available data it follows that the Russian fuze is not programmable, as with foreign developers. The projectile receives an optical receiver to receive the signals of the control laser. The fuse does not have the ability to independently determine the range, for it does the OMS of the combat vehicle. When the projectile reaches the desired point, a command is sent through the laser channel to undermine it.

.
This allows you to significantly reduce the cost and simplify the system of remote detonation.

[Saxahorse]

Quote: riwas

Misunderstood.

Specially versed in this matter in that old dispute. I understood everything correctly. There is no question of detonation when it flies, on the contrary, just like with an electromagnetic system, the distance of the detonation is immediately set by the laser after the speed of a specific projectile is specified by the same laser. The whole difference in the type of signal, the Swedes have induction, we have an optical sensor. (by the way, the same as ATGM)

Do not forget that the projectile can (and should) be shot from closed positions. In this case, the projectile is not visible from the point of the shot at the time of detonation.

In principle, this is possible! But in practice, this is usually not done ... There are, of course, projectiles with a non-contact (for example, laser or radio frequency ...) fuse, which "themselves determine" the moment of detonation; but "remote-programmable" fuses are programmed when the projectile is launched from the barrel or in the barrel based on the data on the range to the target received by the rangefinder before firing ...
The aforementioned shells can be attributed to shrapnel ... But there are also fragmentation-beam shells, which form more "diverse" fragmentation flows ...

So he'll just push forward. Besides, according to the drawing, there is something like a cumulative funnel. A directed stream of gases under high pressure is created, striking forward along the axis of the projectile. It pushes the axial elements forward, possibly breaking the shell of the shell. And the excess pressure imparts diametrical acceleration to the lateral "columns". And then the oncoming air flow completes the rest.

35 mm - the minimum size for ammunition remote detonation, allowing you to make a cheap fuse based on civilian electronics. In this case, the projectile itself is already quite large, and can carry a solid explosive charge or GGE.
If the caliber is less - archidorog. If the caliber is more than 35-40 mm - this imposes its limitations - less common, more weight and dimensions of the ammunition, the gun itself is larger, the ammunition is less ... etc.

In general - 35-40mm - this is currently optimal

[Saxahorse]

The article is curious and detailed, thanks to the author!

But with regard to the subject of discussion, many questions were revealed to its real effectiveness. Recently, claims about the famous American six-barrel, Mark 15 Phalanx, have been debated. To some surprise, it was found that 2-3 hits of a 20 mm projectile by RCC were completely insufficient to destroy the target. It turns out that when it hits the front, the warhead does not detonate as a rule, it is armored (!), The failure of the guidance system does not deviate the projectile from the course, the wheels simply stand straight. As a result, a minimum of 5-7 hits of 20 mm shells is required to bring down the anti-ship missiles, otherwise it, even damaged, will still hit the target!

In general, as I wrote above, the most unpleasant targets such as anti-radar missiles, barrage of ammunition and long-range anti-tank missiles can not be brought down with shrapnel weighing 0.6-3 grams. It turned out a weapon against plywood reconnaissance drones at best. Although the infantry, for example, also does not seem a little ..

If someone did not notice, the current trend of missile defense has become the requirement of direct, kinetic target destruction. With all your weight right in your turnips! This is the only way to guarantee the destruction of an enemy’s shell.

[Tcheluskin]

A link is not specific test facts do not lead?

An armor-piercing 20 mm caliber projectile penetrates ~ 30 mm of homogeneous steel armor. The anti-ship missile "reservation" is an order of magnitude weaker, and such a projectile must pierce several rocket compartments at once.

As for these AHEAD shells, they probably should make a combined warhead: rods + small fragments, increase the volume of explosives, and make the internal profile of the shell so that it would produce fragments of a given size when undermining. It seems to come across information that the developers think in this direction.

Problems with Mark 15 Phalanx google please yourself. It is known that he has no one real combat episode in the black. But serious fails, including shelling the Missouri battleship (the robot took the battleship for a very thick and tasty rocket ) or a serious defeat of his ship with the wreckage of a target rocket, the Phalanx is on the account.

All the more obvious is the problem of insufficient damaging effects when shooting with virtually duck shot.

In general, such a gun is interesting as a weapon for infantry fighting vehicles, for example, but you should not count on it as a missile defense system.

Modern ships, except, possibly, flagships, have no reservation; it’s good if the case is steel, not aluminum or composite. As I understand it, the anti-ship missile pierces the case simply due to kinetic energy, while the front hardware compartment of the anti-ship missile is destroyed, but undermining the warhead located behind it.

The weight of a steel armor plate 33 mm thick with a diameter equal to the diameter of the Onyx anti-ship missile system is 90 kg, or ~ a third of the warhead weight (and it will protect the missile only from small heading angles). I doubt very much that such a booking is actually used.

Yes, probably fragments of 3 g may not be enough to affect RCC, but I think rods of 15-20 g will already cope with the task (although, of course, I have no links to the real parameters of RCC). At the same time, the combined armament-fragmentation warhead should be much more efficient in the consumption of shells against less durable targets: drones, planning bombs, etc., compared to shells without a programmable detonation.

By the way, the developers say the rate of fire of 35 mm shells is 1000 rounds / minute! It is interesting what rate of fire can be provided in a caliber of 40 mm.

50 mm steel is used in the bow lining of icebreakers.

The plating thickness of Arlie Burke destroyers is 1/4 inch = 6.35 mm ("regular", not armored steel).

Some kind of nonsense .. You would at least indicate in which place you found such a skin:

The thickness of the outer skin depends on the length of the vessel, the height of the side to the upper continuous deck, as well as on the draft and the distance between the frames (spacing). This thickness is about 20 mm for ships with a length of 5 m, and about 250 mm for ships with a length of 25 m. But even with the same vessel, the thickness of the outer skin is not the same everywhere. Thus, during a wave, the ship experiences the greatest bending stresses in the middle part, therefore the sheets are thicker there than at the extremities. As a rule, shirstrek and horizontal keel are also thicker than other singing sheets, because they are important longitudinal bonds and are additionally subject to loads acting on transverse bonds.

Ahha. For BMP it a fortiori not interested.
And I especially liked the passage about the fact that you can break through brick walls with a half-kilogram tungsten mass. Of course it is possible. Only now the price of 0,5 kg of tungsten-carbide alloy by itself will cost about 150-200 dollars in the domestic Russian market, plus the payment for the technology for the manufacture of "washers" and "packaging" received in a projectile - we will reach all 300 And they should be dumped in hundreds of thousands in case of war.

For a BMP, a shell with a programmable detonation is interesting for firing not on walls, but on infantry in a field or trench (with detonation above the trench). For this, tungsten is certainly redundant; and we need a larger mass of explosives.

And if we think about a new universal caliber for infantry fighting vehicles, and for short-range air defense - a minimum of 40 mm is still desirable for infantry fighting vehicles, from the point of view of the power of an armor-piercing projectile. But for air defense - the question is, what rate of fire can be provided in a caliber of 40 mm.

Is Skyshield the same one guarded by that same Saudi refinery?

The weight of the GGE is reduced to 1,24 kg.

Typo !!
1,24 grams

By and large - the first programmable shells, this is card-shaped - in field artillery with a gap being set at the right distance, in the zone where the enemy’s manpower is located, and anti-aircraft - in anti-aircraft artillery with the time to detonate at the right height.

In vain you are so ... against kamikaze drones and like the weapons of the last mile against rockets, that's it. It is necessary to take into account not only the speed of shrapnel, but also the speed of the attacking rocket. At small heading angles, at least 1500 m / s will be obtained in the reference frame of the rocket, and this is already more than double the kinetic energy. And if the rocket is supersonic?
Another thing is that it is not suitable against PKR. Googling, for example, the device of the warhead anti-ship missile "Granit" - he will not even notice the shrapnel. And in general, the BB itself is also quite an armor, it does not detonate from shrapnel.

[DeFalco]

Hmm, the drone performance is obvious. Can these shells hit anti-ship missiles?

[Thoe]

As the situation in Ukraine has shown, programmable projectiles would be effective against light drones, of which 95% of all used in the conflict.
