"Barrier from granules and shrapnel": a promising cannon missile defense of British frigates

The promising British frigate Type 31 will not receive anti-aircraft artillery systems traditional for warships, such as, for example, the CIWS Phalanx. However on navy believe that it is quite possible to do without the "Phalanx", replacing it with a new cannon system Bofors Mk4 (two guns of which must work together with one 57-mm gun mount Mk3).

The new product is planned to be integrated into the sensor system of ships to fight against a wider range of targets than the highly specialized CIWS, and make it fully automated. The Mk4 weighs 2,5 tons (taking into account the mass of one hundred shells), the maximum firing range is 12,5 km, the effective range is up to 10 km, the maximum rate of fire is 300 rounds per minute, the angle of attack is from -20º to + 80º.

The Mk4 was designed from the outset to use the 3P ("pre-fragmented, programmable, non-contact") programmable ammunition created by Bofors. The gun can fire with standard and cheaper PFHE OFS or AP rounds.

_{Sectional 3P projectile}

But in theory, the 3P is more effective, as it requires fewer rounds to neutralize each target.

- noted in the Navy Lookout edition.

According to the developers, due to the use of new Mk4 ammunition, the gun will have greater accuracy and firing range. At the same time, he does not need the rate of fire of traditional ZAK and it will drop significantly.

The Type 31 is capable of thwarting a missile attack with two 40mm and one 57mm cannons.

- explained in the press.

According to the author, upon detonation, each 40-mm 3P projectile creates a "barrier of tungsten granules and shrapnel" of 140 square meters. m, and a 57-mm shot - a kill zone with an area of ​​400 square meters. m.

Combined, these 3 cannons can quickly erect a destructive wall of metal around the ship that will be difficult for any missile, aircraft or small craft to penetrate. For dealing with a massive swarm of boats or UAVs, this is a particularly effective combination weapons

- indicated in the publication.

As the author notes, if the Mk4 is successfully used on the Type 31 frigate, other warships of the British fleet can receive a promising cannon missile defense system.

A good idea, the new is a creatively rethought old. But this is a shot of the last line, there will be no second chance in the event of a miss and a missile of the projectile.

[PN]

Something I didn’t see the stabilization of the gun, it was swinging it along with the boat. So the spread will be too large.

[lucul]

"A good idea, the new is a creatively rethought old. But this is a shot of the last frontier, there will be no second chance in the event of a miss and a missile."


Supersonic missiles have a lot of inertia, even if they can destroy the missile with the whole squadron - its fragments, thanks to inertia, will make a sieve out of the ship.)))

[Alex777]

The target speed of these cannons is lower than the speed of our supersonic missiles.

[dauria]

Supersonic rockets have a lot of inertia

As if our anecdote was read, you bastards.
"I have a cat, a bastard, it will pump, accelerate and ride its ass on the carpet. So I pasted the sandpaper - some ears reached the battery."
So their speed is great - some ears will reach the ship on such a grater. I have only doubts about the density of such "hailstones" in a cloud. 10 x14 meters with a step of 10 cm and then 14000 gradations are needed in one layer. Even half a gram - 7 kg per projectile. Well, take into account that 5 rounds per second - somewhere it will be so.
Yes, perhaps from the radome of the rocket radar at 2 speeds of sound, rags will remain. Yes, and somersault - it will fall apart immediately.

I don't know how Onyx is now, but Granite was supposed to keep the Volcanoes and Sparrow fragments from hitting.

[Klingon]

Well, I don’t know if there are enough tungsten balls to shoot down a monstrous super-sonic missile such as Granite or Onyx, there is a chance that the ByCha, albeit with damage, will still get the trough. You can not start a conversation about all sorts of Zircons.
I understand that when sucking on ideas with these pukals, we proceeded from the fact that the trough would be attacked by rockets similar to theirs Harpoons, Axes or our Caliber, low-flying subsonic and relatively small-sized. Well, yes, against Drono-Jonko, all kinds of air mattresses with a motor and flying Marines, such a system will work fine

[Barberry25]

Well, it's not a fact, if the control surfaces are disabled at a sufficient distance, this can lead to a change in the trajectory, as an auxiliary weapon, it can even go in, As an option, we can add combat modules on ships of the MRK level and above ... the same Pantsir-ME need to be modernized and replaced with a 57 mm cannon.

[Bogatyrev]

Caliber in the final section of the supersonic

[riwas]

Well, I don’t know if there are enough tungsten balls to shoot down a monstrous super-sonic missile such as Granite or Onyx, there is a chance that the ByCha, albeit with damage, will still get the trough.

"Granit" has a large inertial mass and an armored warhead, made specifically to protect against anti-aircraft fire. In any case, the target will reach.

[Dr_Chimer]

Interestingly, will they stop Zircon too?

[O. Bender]

Yeah, team One-two.

[evgen1221]

But won't the boat be too small to shoot at it with such an expensive rocket? Maybe this was the idea.

[Alex777]

Quote: Dr_Chimer

They won't even notice Zircon.

[Alexander Samoilov]

At the expense of missiles, I'm not sure, but against UAVs - that's what you need.

[Alexander Samoilov]

About missiles, I don't know, but against UAVs - that's what you need.

[Basarev]

Isn't it a little expensive to shoot with such clever projectiles? Wouldn't it turn out that it would be cheaper even with a laser, for example, to timely detonate a warhead at a safe distance?

[Barberry25]

Now lasers can burn a small-sized UAV made of plastic, but rockets are no longer a fact .. in the most optimal case, lasers can now be used to disable the missile's seeker

[Avior]

The fashion appeared on 57 mm guns, the Americans also put on the frigate.
On the one hand, it is clear what has been done against the UAV and the mosquito fleet, on the other hand, it cannot be called a universal weapon. Basically, the balls in the 76mm projectile also create a bursting field, and the 76mm is much more versatile and long-range.
And against anti-ship missiles, small-sized missiles with a radius of 10 kilometers are better suited.
On the other hand, Oliver Perry got along with such a tool.

[Graz]

According to the author, upon detonation, each 40-mm 3P projectile creates a "barrier of tungsten granules and shrapnel" of 140 square meters. m, and a 57-mm shot - a kill zone with an area of ​​400 square meters. m.

oh, they say how they breathe

[hohol95]

And will it cope with vertically falling ammunition?

[faterdom]

Quote: Dr_Chimer

Of course!
1. Will see "Zircon".
2. Will report to the cap.
3. Get directions.
4. Will answer "Yes, sir!"
5. Load 40 and 57mm rounds.
6.Aim on the "Zircon"
7. They will receive the command "According to Zircon, doublet - Fire!"
8. Answer "Yes Sir!"
9. Calmly press the electric release button.
10. They will fall into the Zircon with balls.
11. The cap will be reported from the exercise.
This is on the teachings of the British Royal ...
In real life, of course, this will not work - after the first point, there is no time for anything.

[hohol95]

Question - "Granule" made of tungsten, how is it different from "shrapnel" made of another metal ???
There was also Harz bar shrapnel ...
Until "granules"!

[Tcheluskin]

They differ in a higher price.

[hohol95]

This is all clear. Tungsten isn't cheap!
But, who came up with such a name - "granule"?
Essentially the same "shrapnel" ...

[Pattor]

It has the right to be. Interesting mathematical calculations of the destruction of flying objects at different speeds and different masses. Yet progress is moving.

[Vitaly Petrov_3]

[quote = hohol95] Will "it" cope with vertically falling ammunition? [Of course, like a diaper with a piece of shit! Caught at 10 !!!

[Borisych]

Francis Drake, pirate, privateer, rogue, rogue, well, he just really loved shrapnel. Well, there was no supersonic sound then, there was not.

[expert]

I remember that I was still a kid, I read military memoirs about the Tallinn transition in August 1941.
Evacuation of the main forces of the Baltic Fleet under the command of Vice Admiral V. F. Tributs and the troops of the 10th Rifle Corps from Tallinn to Kronstadt.
The entire transition was accompanied by continuous German air raids.
What struck me then was that the skies were periodically cleared by main battery guns firing shrapnel.

[Sergey Kulikov_3]

Rate of fire 300 rounds per minute, 100 rounds of ammunition, 20 seconds of combat, the supply of shells? Yes, not a lot today with the protection of seafarers, which, in principle, was expected.

[mmaxx]

Angles are great entertainers. In WWII, planes were caught with nets. Now the rockets are tungsten balls.

[bk0010]

So what? They say that the first means of the Grand Fleet PLO were the sailors in the boat, who were supposed to jump onto the submerging submarine and break through her hull with pickaxes (if this is not a bike, of course). Spin as they can.

[Split]

But in theory, the 3P is more effective, as it requires fewer rounds to neutralize each target.

Against hypersound, I'm somehow not sure that it will be effective - due to the fact that the gun itself will not have time to hover ... a couple of tons still cannot turn at least 90 degrees in a split second

[Jacket in stock]

Isn't the target too small for supersonic?
Onyx, I suppose, stands as half of such a boat. And Zircon is even multiples of it. According to such rules, we have simpler, cheaper missiles, such as the X35. And against them the shrapnel from the 47 mm cannon will do just fine.

[Split]

Well, if according to your theory it does not cope, so will the rocket get more expensive? Not?

[Momento]

turning on any cannon is much easier than a hypersonic missile. then if the rocket is not armored, then the shrapnel is definitely enough - the main thing is not to get within 50 meters.

[Max PV]

The problem of cannon artillery in missile defense of ships is that this is a weapon of the last frontier, designed to destroy missiles seconds before they hit the ship, and disabling the GOS, control systems, damage to the engine and airframe, only reduce the chances of hitting. The rocket will either continue to fly by inertia, like an unguided projectile, or, if equipped with a control system and INS separate from the GOS and the INS behind the warhead, it will continue to aim according to the latest GOS data. The only reliable option is the detonation of the anti-ship missile warhead. But the point here is that modern anti-ship missiles are equipped with penetrating warheads with an extremely durable body from tens to hundreds of millimeters of steel. And all this is covered in front by a spaced-apart screen from the fairing and the seeker. In fact, an anti-ship missile warhead is the level of security of light and medium armored vehicles somewhere from BMP-3 to Bradley in full body kit. Now imagine that you need to destroy, okay, even our BMP-3 with shrapnel or shrapnel from a 57-mm projectile in the forehead.
For an idea of ​​booking a target (Exocet, Harpoon and Granite):

[victor_47]

The nuclear warhead of an attacking missile, detonated 1-2 km from the ship, will destroy at least all the control and guidance systems of this ship, after which its final destruction will not be a problem for the most antediluvian anti-ship systems.
