If memory serves me right, Korean gun of K9 SPH had shorter lifespan than German gun of PzH2000 SPH. Thus, I mean, even if aidic's info is right (which I doubt till source is on), there will be still many speculataion to be considered before massproduction for XK2 guns.

Well, world is already covered by Rheinmetal guns! Some variation be good.

Welcome aidic

And from whom may I ask are you getting this particular information from.
sorry i can't tell the exact source but you can judge this data is credible or not

the exact penetration (korea new APFSDS(xk2))is secret but some sources are said that

L55 850mm (1km) (or 900mm)-(i don,t know which is correct)
and

muzzle velocity is nearly 1850m/s

it's a experimental data

the exact data is secret

I agree, it is not 100% true, but what I would like to tell you that this kind of websites are available on the net. I only use it to get an idea, not for the real statistics.

Like I told above, with an example with the Turkish M48 that destroyed a Greek tank, according the this website it was unable, but in war in was ABLE to penetrate the armor of many similar tanks with the 90mm tank gun.

For using it in war games? No surely not. They have their own penetrating statistics in war games.

Big shell pocket ain't it?

I too do not understand the rush to roll out a new design when the K1A1 is more than sufficient to counter anything operated by N.Korea. It's not about obtaining the most advanced piece of equipment, but rather one that suits you.

I too don't understand why so many of u are saying there is no need for this or that. Its called technological advancements! Considering how unstable N. Korea is, there is every need.

Its got amazing features. The top attack feature of the weapon system is almost like the holy grail of many tank weapon designers. Attacking the thin & weak top armour could potentially allow it to defeat/bypass the best armour like Chobham armour on even the M1 Abram or Challenger tanks since its very bulky, needs to be flattish and not found on top. Its only something recently added to anti-tank missile weapons which is still very expensive per shot. This is the first time I've seen it implemented in a tank gun. Guided ammunitions too, for a tank gun, that puts it easily above all the M1-Abrams, Leopards, Challengers etc. It also means that for once, line of sight to target is no longer needed! U can park this tank on high ground, in a tank fox-hole dug-out and lob precision guided shells, artillery style at targets up to 8 km away! So far the record for a hit is only 4km or so (Challenger tank in Iraq/Afghanistan). Or the shells can be guided by a forward recon scout illuminating the target.


Watching the video, I'm quite impressed by the acoustics. There is no characteristic roar of diesel engines that usually give away the position of a tank. It appears quieter than some of the street double-decker buses on the streets! Though that could be a volume normalisation issue.

Furthermore, the active suspension is I believe something that ought to be standard in any modern tank. It lowers the front profile in the squatting position, decreasing target size & improving survivability. Furthermore, by lowering the front suspension, you can shoot downwards, so critical when adopting a high ground defensive position.

& no, to all those talking gibberish about the size of the tank - its got nothing to do with the humans! You need better understanding of tank design. Small is much better - lower cost, lower weight, better soft ground performance ,higher power-weight ratio, means faster acceleration, better fuel economy meaning longer range, meaning less vulnerable logistical supply line (unlike the M1 Abrams), lower target profile, increased survivability, easier long haul transportation/deployment by trailers or planes ... ...

The US think-tanks have long since concluded that the M1-Abrams will be the last of the big MBTs. Its replacement will be much smaller & cheaper.

That's why if you were any knowledgeable at all, this Korean tank is a much needed step in the right direction. Another big step for the Asians. But I'm not surprised, between the world leading car making (Hyundai, Kia, Daewoo), ship/steel making & especially electronic/semi-conductor (Samsung) industries, Korea is uniquely equipped to make every world class component domestically. Not many countries can.

It is always nice to be enthusiastic about a new toy of ones own country. Who's not? (Ok me on too many german systems :D )

But there are some things you have to consider.

Defense against top-attack ammunition is not a feature of a new tank it is a feature of a active/passive self defense systems which can be adopted to a wiede variety of vehicles. The russians did this. The Israelis are going to do it with trophy. There are german and US systems in the pipe. Those can be added even to a T-55 if the customer whants it.

And what kind of intelligent 120mm round do you mean. I missed that one cold you give me some infos? :)

BTW, the record is at ca. 5km by a Challi in Iraq. Do you have an idea how small a tank gets at such ranges?

The actice suspension is really nice there I totally agree.

More cramped working stations can also mean less combat crew performance. Just do add a negative side to the very true positive aspects you stated.

As for the leading nation. I can still think of many other countries which match these capabilities.

And for sure technological advancement is important.
But the problems on the export market for tanks these day have already been mentioned.

"It is always nice to be enthusiastic about a new toy of ones own country. Who's not? (Ok me on too many german systems )"

- New toys? Who gives a hoot about which country it comes from? This is supposedly a forum for defense issues for mature folks, not boys

- So much of this forum comprises of this kind of partisan childishness.

- Try considering this. Given that the traditional tank producing countries are all still suffering from indigestion from the Cold War tank race & either lack the political will or military justification for new tanks, this Korean tank represents the first implementation in an actual service deployment model for a long time. What has been bandied about by the Western countries has been actually implemented by an Asian technological powerhouse but some Westerners just dun seem to want to acknowledge it. Tsk tsk.

- Considering the frightening prospect that the whole world is already buying state of the art harddisk drives, SSDs, DRAM, NAND, CPUs, LCD panels, laptops and telecommunications (btw all that can be supplied by just 1 single Korean company - Samsung), this Western persistence in smirking is incredible.

"Defense against top-attack ammunition is not a feature of a new tank it is a feature of a active/passive self defense systems which can be adopted to a wiede variety of vehicles. The russians did this. The Israelis are going to do it with trophy. There are german and US systems in the pipe. Those can be added even to a T-55 if the customer whants it."

- Precisely the point. Pipeline dreams. While the West is still dreaming it, the Koreans have already implemented it into service and beginning mass production.

-What are you talking about? What good is a new tank if it does not acknowledge the threats in this current climate enough to integrate active defense systems as a standard? The Korean tank has implemented it as a standard system within their tank and kudos is due, whatever skin colour you happen to have.

- Furthermore, I was not stressing too much about the active defense system precisely because of the many albeit disparate and expensive options that u mentioned. Try to catch the point, its the implementation of top-attack ammunition IN A 120mm TANK GUN that changes the paradigm.

- It makes all current modern tanks vulnerable UNLESS they have an active defense system in place as a std. Or put Chobham armour on top. That is the issue!

- Its no longer about brute force in an APDS shot from an ever bigger gun.


"And what kind of intelligent 120mm round do you mean. I missed that one cold you give me some infos? "

- Try familiarising urself with the specs again before you miss something so critical to the current tank warfare paradigm.

"BTW, the record is at ca. 5km by a Challi in Iraq. Do you have an idea how small a tank gets at such ranges?"

- Do you not realise how the size of a target at any range is irrelevant? In this day & age of thermal imaging optic sights etc.! Whats the point u're making?

- That's the whole point of this implementation of a top-attack precision guided ammunition of the 120mm tank gun capable of a range up to 8 km! It made me sit up when I read it.

- No doubt the tanks in Iraq are probably creating new records everyday even as we type away. But the real issue is that any such hits in a real engagement are likely to be due to luck - i.e. stationary sitting duck target with constant environmental conditions.

- The current computerised fire control systems on tanks work only on a few key parameters. Eg. Laser rangefinders to compute range & azimuth to target, followed by environmental sensors to input temperature of gun barrel, air temperature, humidity, atmospheric pressure, wind direction, followed by algorithms that can at best work out other exotic factors such as progressive tank barrel wear & tear. At the extreme ranges of 4-5km, given the flight time of a few seconds, once the shell leaves the barrel, without precision guidance, it'll miss so long as the target so much as moves or changes direction unexpectedly. Or if the crosswinds or other atmospheric conditions BETWEEN the gun & target differ from the estimates of the tank's FCS.

- Precision guidance is the only way to break this paradigm, try to appreciate that first.


"More cramped working stations can also mean less combat crew performance. Just do add a negative side to the very true positive aspects you stated."

- Again, outdated paradigm. Modern tanks are different from the communist Soviet era tanks that u are clearly referring to. The communists never had regard for human safety, let alone welfare. Unlikely that the Koreans, a democratic country, given their auto-making expertise and appreciation of human ergonomics would neglect this.

Smaller exterior dimensions do not always equate to cramped interiors. The tank requires a crew of 3, not the 4 crew of 2 decades old Cold war Western tanks vintage. Autoloaders built into a tank represent 1 less person to legislate for comfort. Smaller more efficient engines obviously save even more space. State of the art computers are a fraction the size and power consumption. Again, its technological advancement

"As for the leading nation. I can still think of many other countries which match these capabilities."

- How? Not many are on actual order in large production capacity, nor will they be in the near future. Again while their capabilities are not in doubt, these countries do not have the appetite for more such investment. For the US the M1-Abram, which already costs a fortune given the huge numbers manufactured & at 65 tons on existing configuration is too heavy to realistically add anything more without a major re-design, its a victim of its own design limitation. There's also a constant fight to put more fuel into every available space to feed its fuel-thirsty turbine engine. After spending a fortune on the F22 & B2 to fight enemies that do not exist, plus funding a 2nd Vietnam in Iraq, they need Viagra for their military brass.

- For the UK, same issue, but furthermore, the Challengers are produced in such limited numbers, its unforeseeable that they can justify launching any new tanks! Perhaps, the Germans with their export success of the Leopard, might be able to afford R&D on a new platform but the politics of it make it difficult nonetheless.

- Which leaves the Soviets ...

"And for sure technological advancement is important.
But the problems on the export market for tanks these day have already been mentioned."

- Again you are totally missing the point. Advanced Asian economic countries like Korea & Singapore (largest weapons exporter in SE Asia) with their compulsory National Service do not build and design weapons purely as a for-profit product for the export market. They do so for national security first and foremost - such as the ability to manufacture unconstrained by licensing restrictions and the security of supply thru indigineous production. In supplying their armed forces (which are usually quite large for economical production given their compulsory conscription) with the best weapon systems for their own soldiers - they trust that if they are that good for their own needs, there will be foreign buyers for their weapon systems eventually.

- Whether there is an export market is irrelevant, its only a bonus, no more than a means to reduce costs through volume production. Try understanding their philosophy, they will commission it at 8.5 million apiece even w/o a single foreign buyer. For such countries, in fact all arms producing ones, even the US, the price for national security is worth every penny.

I do not place alot of faith in some of these counter measures that are out there on the market today, one good artillery barrage that a vehicle will most likely encounter will rip or damage these systems, thus one of the reasons why we have been slow going to them.

The best way to defeat them is to 'Fix' them with combined arms forces and then attack from the flanks. One of the simpliest NATO tactics, it's cheaper and already on the battlefield, without too much systems on your tank. Tanks must not be like a Christmas tree with everything like toys and candies on it but it must be plain and simple with one good thing outside: The accurate maingun! With interior the high tech under armor. Also reactive armor is a good way to defeat the STAFF (Smart Target Aquisition Fire & Forget) round fired from the Abrams, the top attack heat round.

Or like in the science fiction movies, there is a big need of an electric shield, like in Star Trek :D not?

For the design of this projectile, you would not be able to place enough reactive armor on top to defeat it at this present day.

and I agree, tanks look really cool with all the antennas and sensors that are bristling on them but they are looking rather comical. A squad machine gun will have a field shooting at these gizmos.
A electric shield is nice, but I like the Klingon approach, Cloaking:D

without wanting to trivialise or oversimplify the issue - its why artillery is fondly referred to as "king of the battlefield" - GMLRS makes that even more so (and I realise that there are a raft of caveats - but in real terms its an indicative absolute)

the paradigm has changed in the sense that the definition of armour has also changed.

armour is not necessarily restricted to a system designed to blunt, obstruct or deflect/defeat a kinetic attack - its also now about systems (such as electronic) that are pro-active (in a defeating sense)

I realise that you're passionate about the subject - but can we also concentrate on the mechanics of debate but avoid the east vs west elements?

btw, I've worked with the Sings and know what they are capable of - I seriously doubt that anyone in the mil industry takes a prescriptive view as you've outlined. In fact, our nickname for Singapore was the "PACRIM Israel" due to its technical competency.

Active protection systems like Arena or Shtora, Drozd, ERA, etc. tanks will not need the 60 tons armor then. With 20 or 30 tons you can do the same, maybe better protection then the 60 tons armor because of the active defensive systems and more economic fuel consumption. But this will be seen after 20 years I think.

No need in BB Battleships, lighter frigates and fast patrol / missile boats are able to destroy such heavy ship as well. We will see how it get's advancements. Maybe the Hummer armed with a advanced lazer gun will take the place of the Abrams in the future???

The problem is that such active protection systems do not work very well against a 1750km/h KE.
It is very nice for giving the tank a 360° protection against a limited number of ATGMs/RPGs/etc but they wont help if you are in front of a high pressure gun with advanced KEs.
There you still need the good traditional armor and maybe some modern ERA.

Agreed - for the present day though, counter measure systems being able to take on the more advanced anti tank missiles fielded leaves alot to be desired, and they can be defeated by the U.S military. When they do become a major factor some day in the future, I would think that they would be able to protect the systems alot better than having them exposed/configured on the vehicles.

When that day happens that you can counter a KE projectile it will probable be the end of heavy armor.

Jup, but this day is far away I think.
Guns and ammo are also on a continious development process. The problem with KEs is that they cannot be jammed and they cannot be destroyed like ATGMs.
I don't see the active protection system being able to do this in the near future.

Tanks w/o tons of Armor... what IS this world coming to?:cool:

K.E.s are so cheap and easy to manufacture that they will always be around, I think. Also, there is the protection it offers from blast weapons, radiation and other things.

There is also the dampening effect that the wieght of armor has on the "ride" in uneven ground. Could a 20 ton tank move with the same stability as a 70 tonner?

Protection against radiation, yes on a temporary level of protection.
As far as 20 ton armor with the same stability, why not this is the weight class that the U.S would like to get in around with the only problem being that trusty high velocity KE round that requires tons of armor for protection.

Maybe when we are ready to field ETC type weapons, then we can get back down to a lower weight class.

No I don't think in the near future. Earlier times we had kevlar bullet proof vests. Today we have kevlar mixed with Borium-carbonhydrate or something to protect from small arms and stabbing. In the 1970's the Soviets used also Borium carbo something in their T-64B's the A version was filled with a foam what increase in size when getting overheated by the HEAT warhead.

Also the new armor can be filled with this Borium material to reduce a lot of weight. 72% of the reserves are in Turkish soil and the rest in China, USA, Russia and a country in South America only, wich country I have fergotten, sorry.

Turkish research institute has finished research for the 25mm plate armor with less weight than steel and gives the same protection level.

Do you really think that what Russia placed in the turret cavities of their tanks was that effective, Borium testing still has a long way to go and the cost for processing is quite high and do you think that it would be better than ceramic used in larger volume and mass, if you can keep it from shattering in cold weather and round impact.:)
