Chapter 399: Depth of penetration
Comparing the above data, it seems that the armor penetration difference between the three is not big.
And because the 170mm K18 has a relatively lower diameter, it is no longer even a long-barreled cannon in the traditional sense but is classified as a cannon howitzer, and its shell muzzle velocity is obviously lower.
[Writing this, I hope readers will remember our domain name Taiwan Novel Networkβπππππ.πππ]
This is normal. After all, the original design goal of this gun was not anti-tank and anti-armor, but long-range fire support.
However, it should be noted that the armor penetration data above are mainly at a distance of one kilometer after launch.
The current situation is that the straight-line distance between Andalil and Luger is no more than 120 meters.
Under such conditions, it is really unnecessary to see the penetration depth of one kilometer.
With such a close distance, in fact, the K18's shell storage speed will be much higher, and its armor-piercing performance will be much higher relatively speaking.
It is obvious that its shell size and maximum weight are the highest, so the energy lost by air resistance when flying in the air must be higher.
If the armor-piercing performance difference between the three at one kilometer is k18:pak44: long 88 = 255:230:165/193, this is a relatively close state.
Then when the attack distance is reduced to about one hundred meters, the penetration depth of k18 must be relatively higher.
What's more, how could Ruger still use the original shells?
This thing has a caliber of 173mm. Not to mention that you can directly use the same piercing rod of the 55x caliber 120mm smoothbore gun DM53 tail-stabilized discarding sabot armor-piercing projectile. It is not a problem to directly use the piercing rod designed for the next generation 140mm caliber smoothbore gun.
Of course, in fact, the caliber of the smoothbore cannon is getting larger and larger, but the diameter of the apfsds penetration rod has not changed much, what has changed is actually the length.
For example, the diameter of DM53 rod is 2, and the aspect ratio is about 26:1.
The diameter of the ancient DM13 rod was 2 long and 315mm, and the length-to-diameter ratio was about 8:1.
However, this does not change the fact that the 173mm caliber K18 can still fire the same penetrating projectile as the DM53.
More importantly, such a gun, including several rounds of adapted apfsds directly modified from DM53, and purchased the finished product directly from the store, cost only 23,000 Ruger points in total.
Yes, this number is still terrifying.
I just hope that its effect is worthy of the price.
When Ruger once again used a "figure-level" cannon to lure Andariel to attack, the Poison Demon King, who had been fooled several times and found that his new cannon was no longer fearful, directly let the cannon pass this time. , directly chased the poisonous light cannon behind Luger's butt and hit him.
In view of this, Ruger simply fired off smoke bombs again, and at the same time threw two or three sets of heavy tank hulls in front of him.
These car shells are not the material energy armor version of the previous Tiger, but composite armor that has just come off the production line and is specifically designed to block gunfire.
It is conceivable that their effect will not be very good.
However, their role itself is not here.
It was used to block guns, yes, but more importantly, it was used to block Andariel's sight.
The black smoke screen will be swallowed up by the poisonous cloud and quickly expire. These iron bumps can at least last a little longer.
At the same time, Luger lay directly on the ground, relying only on the pulleys on the breastplate and the rocket booster to move near the wreckage of the previous artillery pieces, and suddenly replaced the remains of an eighty-eight-year-old cannon with that The barrel of the K18 that just came out of the oven.
Well, that's right, it's another version with only the gun body and no gun mount.
In this way, its size can be controlled to be smaller, and it will not be too eye-catching compared to the remains of the Changbaba Cannon.
Sure enough, Andariel saw black smoke reappearing over there, and at the same time, there were more tank-like things inside, and he immediately spent most of his energy on dealing with them.
You must know that she believed too much in her poisonous light ball before. After throwing three shots at this kind of thing, she assumed that Luger had been killed by her. As a result, she turned around and was tricked by him again.
So this time she directly made up her mind, even if the light cannon magic that maintained the offensive and defensive protective cover did not stop, everything in the black smoke would be corroded. After seeing Luger's bones, she Will turn around and leave.
As for what to do with the two armored female warriors behind them during this period of time?
Then just use the protective shield to resist.
Even though Tiya and Sarah used various high-power moves to hit him in turn, Andariel insisted that Luger would not let go.
This shows how much she hates Luger.
Luge, who was lying on the ground secretly rubbing her sex, saw her like this, and couldn't help but break into a cold sweat on his back.
The heart says what on earth did he do?
Was it the hatred for killing his father and the hatred for taking his wife away, or was it because he was in chaos and finally abandoned her?
Wasn't it just that he had cheated on her a few times, that's all!
Although he was secretly complaining, his hands were not idle at all.
I completely didn't realize that my current behavior was yet another sinister act.
And this time, it was quite dark.
This 173mm cannon howitzer has a diameter of 50 and a barrel length of more than eight and a half meters, 8625 meters.
The long 88 gun has a diameter of 71 times and is only over six meters long.
The barrel of this thing alone weighs nearly ten tons.
It was also because of this that this time Ruger failed to fire the cannon as soon as he took it out.
But it seems that this cannot be said.
Because, even after all his efforts, he still hasn't been able to get the barrel out successfully.
Why?
Didn't he get a tank weighing dozens of tons out before?
Yes, that's right.
If he just found a place to throw it, he would have gotten it out long ago.
The problem is, wasn't he lying flat on the ground, and quietly thrusting his long, thick, and heavy thing towards Andariel's vitals?
Ahem, it seems ambiguous.
Get the point~
In short, the posture is wrong and the requirements are high. Of course, he can't do it for a while.
Seeing that the black smoke over there was almost swallowed up by the poisonous cloud again, and even the three sets of modified Leopard tanks with tilted composite armor left on the ground were almost completely melted by Andariel's poisonous light cannon, Ruger became more and more anxious.
No, if it goes on like this, it will be too late!
Ruger estimated that it was not good, and he gritted his teeth and used telekinesis to lift the nearly ten-ton thing again. He just poked the barrel into the wreckage of the artillery in front and fired at Andariel's side.
"Boom~"
A sound that was far more violent, dull, and long than the previous cannons sounded, and the tungsten alloy rod with a length-to-diameter ratio of 26:1, the same as the DM53, flew towards Andariel at a speed no less than six times the speed of sound.
Andariel had actually noticed that there was a problem when Ruger poked the cannon forcibly, and turned around to move the light cannon over here.
But the distance between the two was not far, and the rod could fly more than two thousand meters in one second, which meant that it took less than 0.1 second or even 0.05 seconds from the time it flew out of the muzzle to the time it hit Andariel's protective shield.
