ATG-44 SHaped Anti-TAnk Mine

[OOC: This is my first ever lineart, so don't make fun of it. I've already gone through with it on Lineartinc, and I promise my next one will be much better.]

Type: Anti-tank
Height: 34 cm.
Width: 19cm.
Weight: 8.9 kilograms
Explosive: 14.7 heptanitrocubane [HpNC]
Penetration: 210mm RHA CE
Detection: Pressure Gauge
Arming: Automatic
Anti-Handling Device: Yes

The ATG-44 uses a very old concept to create a very modern anti-tank mine. The concept of the charge dates back to the design of the Panzerwaffe, one of the most infamous German anti-tank rockets which wreaked havoc on Russian and Western Allied tanks alike. Of course, surfaced rockets like the Panzerwaffe have long become obsolete, however, the ATG-44, unlike these others, bases itself underground, as an anti-tank mine.

When the shaped charge ignites the force is concentrated on the hollow center infront of it, called the Monro Effect; more specifically, A forceful jetstream of the explosion gases results that hits the steel target with a speed of typically 15000 meters per second and penetrating pressure in excess of 12 million kg/cm2. When the explosion occurs, the liner metal is formed into a spike of molten metal (although there is some discussion on whether it is liquid or solid; most times it is referred to a "plasma" jet, plasma not in the technical subatomic sense but in the sense of an in-between state of the metal between liquiduous and solid). To be most effective, the shaped charge has to be detonated at the right distance from the target. If it detonates too close to the armor, the plasma-jet hasn't formed out before hitting the surface and the effect is lessened somwewhat. If detonated too far from the armor surface, the plasma jet has unfocused and partly spent itself already (this effect is used in applying spaced armor, described below).

The ATG-44 has an anti-handeling device that also sets the fuse, like the pressure gauge, allowing the mine to blow before it can be dismantled. It's a safeguard against mass mine dismantling programs. Also, there is very little metal in the mine, making it more difficult for mine detectors to detect the ATG-44.

The fuse works with a small pressure guage [the green part of the mine], that is enlarged in the picture, but in true use only sticks up from the ground for about half a centimeter. It measures the pressure on the nearby surface for about two meters, taking in mind the weight of vehicles and the such. It's designed to set the fuse for vehicles over two hundred kilograms, and waits until the vehicle is more or less centered over the mine, but detecting pressure crafted by the tracks or wheels of the vehicle. It has proved to be a highly effective method of setting the fuse.

The ATG-44 does not have a self-destruct option. It is to say, the mine is there to stay until it is detonated or dismantled by professionals that know the mine well.


Cost: $300 USD

Not a bad design, though if the tank it's used against is equipped with full-body electric reactive armor, it won't do much besides suprise the crew.

Umm, you tell me your tank has ERA blocks on its belly, and I'll ignore them moving. You're not going to have over 300mm rolled homogenous armor on your tank belly, I'm sorry.

Hmm, good design Mac, though I think the importance of mines on NS is over looked may too much, not to metion most people have vehicles that can "magically" find/go over/destroy minefields.

Just how tall is the pressure gauge? If it's to small tanks may be able to roll over it if the tracks miss it.

OOC: You did inspire to make an advanced minesweeper with this, it sounds so impressive. Thanks for reminding me about mines :)

[ooc:My only regret about this OOC is that you posted it like a day before I finish my Dynamically Staged Explosively Forged Penetrator Warhead concept... its good though, once I finish the concept piece I'll let the IADF know about it.]

[OOC: I don't understand much about distribution of pressure on the tracks, but let's assume that this would be destroyed. I would suspect there would be enough for the tank to be taken out by the next one. I would also suspect that the pressure of the track on the ATG-44 would cause the mine to blow anyhow.]

Er, electric reactive armor isn't explosive blocks. It's something the British developed a while back.

However it is more likely to hit the belly-- simply cause the belly has a larger surface area.

It's designed to hit the belly. The only problem is that the the armor, which I used to use on my tank myself, is not designed to be included on the belly, simply because the idea of having to put another dimension on the tank [e.g. from the sides and front of the tank, to the bottom], and the fact that a lot of the armor's strength comes from the ability to just pour the copper and use gravity, while doing that on a flat surface on the bottom would be overly expensive [because of the addition of someway to push it along] makes it implausible to have there.

The technology is designed to stop RPGs, not mines. The concept of both are the same, but the RPG is designed to hit on the side - which explains why it's easier to use this to defend against them.

For those wiseguys who think its a great idea to add 350mm of armour on the bottom remember, you have to be able to pass over rocks. If you add too much, you can't move over little bumps. Time to mine things. Mind making an airdroppable mine?

Sure. Do you want it to be anti-personnel or anti-tank? The latter would be more difficult, because a big one would be quite obvious, while anti-personnel mines can be rather small and still do damage [tear apart limbs, etc].
