Speed is the greatest weapon.

There can be many interpretations of this sentence, the mysterious one can be said to be "the world's martial arts are only fast and unbreakable", and the poetic one can be said to be "in the face of the extreme speed that surpasses everything, any protection and attack are meaningless". In physics itself, this sentence is literal.

The faster the speed, the greater the kinetic energy, the greater the penetration, and the stronger the power. Even if it's just an ordinary coin, when fired at Mach 3, it's still a lethal weapon. Even if the other party is the so-called "right hand of God", he will still be killed on the spot. This is not hypothetical or conjecture, but objects moving at high speed are so terrifying.

In the same way, when a stone falling from a height of 10,000 meters and accumulating kinetic energy during the fall process accelerates during the fall, it will also have a destructive effect equivalent to that of a bomb. And what about the steel battleships that fell from the sky with a weight of 1,000 tons?

Although there is a convention in various countries that warships are considered women, I believe that no one will be "moved" by the feeling of a battleship girl falling from the sky. Whether he is a European admiral or an African native, there is only one reaction when he sees thousands of tons of steel smashed down on his head, and that is-

"Mamma Mia?!!!!"

The first mate at the helm let out a woman-like scream, and the face that rippled under the impact of the G-force was also like a girl riding a terrifying roller coaster.

In fact, if you compare the high parabolic trajectory carefully, you will find that it is really similar to the initial section of the roller coaster track, which will also go through a relatively slow climbing process, and then the same rapid falling trajectory, and the whole trajectory is also very steep. It's just that this side climbs higher, falls faster, and the G-force in the cabin is greater. At this moment, everyone was firmly fixed in position, and the crew was tied up like a death row prisoner, and the load of gravitational acceleration combined with the terrifying scene of the ground magnifying at 600 kilometers per hour in front of him, no matter how brave he was, he couldn't help but have the urge to scream.

Perhaps they should be glad that at this moment the rocket has separated from the hull and no longer provides additional power. Gravity accelerates an object as it falls, but air resistance is proportional to the square of the velocity. When the thrust gained from gravity is equal to the air resistance, the velocity does not increase anymore. In other words, as long as it is diving in the atmosphere, no matter how high it falls, the speed has its own upper limit, as long as there is no additional power boost, the speed of 500~600 kilometers per hour is the upper limit.

600 kilometers per hour is not a particularly serious test for the defense forces' anti-aircraft weapons, and their own large attack aircraft often use this speed to dive at a vertical angle of almost 90 degrees, and the air defense units on the Siegfried Line have long been trained in this area. As early as the radar signal of the Endeavour was captured, the air defense forces sounded the combat alarm, and as soon as it was confirmed that the enemy was beginning to enter the dive course, the air defense command immediately launched an attack.

"Target designation radar, target detection and reporting!"

"Azimuth 010, altitude 13200!11 kilometers away!"

"Guidance radar, turn on!"

"The guidance radar is on!"

"The guided rocket is in good condition and ready for launch!"

"Launch!!"

As soon as the air defense commander gave the order, three "Waterfall" guided air defense rockets took off into the air, and three shining fireballs quickly swooped down on the target in the high air.

As the only country in the world to develop missiles on a large scale, Yalfheim has been somewhat constrained by the will of the supreme commander, with the only exceptions being the Fi-103 cruise-guided rocket and the R1 Waterfall anti-aircraft guided rocket. The reason, of course, is the needs of the battlefield.

The Defence Force has never neglected the question of how to defend its own heads, because the Air Force has a heavy task and cannot hold up a protective umbrella at all times. Reliable anti-aircraft weapons become the second line of insurance against enemy air power. In addition to a variety of high-performance anti-aircraft guns, guided rockets were also included in the vision of the defense forces, and among several proposals proposed by Peneminde's team, the "Waterfall" was finally chosen, the least aircraft-like anti-aircraft missile (the earliest generation of anti-aircraft missiles almost all grew into airplanes).

The shape of the "Waterfall" resembles the A-4 guided rocket, which in fact is the anti-aircraft version of the A-4 guided rocket. The aerodynamic layout is basically similar to that of the A-4, except that the physique is reduced to a quarter of the latter. In order to increase the maneuverability of the missile, four side strip wings were added to the middle part of the missile body. The guidance method has also been changed from inertial guidance to the most advanced Rheinland system, which tracks the target by radar, and the radio command receiving device on the missile receives ground commands to lock onto the target. When the "Waterfall" is launched, the tracking radar will also input its motion parameters into the calculation terminal, and the terminal calculates the guidance command to transmit to the missile, and the radio receiving device converts the command into a signal to control the missile to guide it to the target. Finally, it is detonated by remote control by ground controllers or by the VT (Radio Proximity) fuse of the warhead. A frantic 306-kilogram warhead is enough to break a large floating battleship in two on the spot (for a simple comparison, the Soviet SA-2 anti-aircraft missile's high-explosive fragmentation warhead is 195 kilograms, and its damage radius is 65 meters at low altitude and 250 meters at high altitude). The 306 kg warhead is almost equivalent to the charge of the YJ-18 anti-ship missile). The only fly in the ointment is that this missile is still very primitive, and there is a strict time limit for the missile to be energized and started, and the missile can only enter the normal use state after it is energized for a period of time, and the power-on time is too short or too long to be used normally.

There are 3 missiles of such an advanced missile in one hit, and it is obvious that Major Heinrich, the commander of the 3rd Air Defense Rocket Battalion, wants to bomb the uninvited guests to the point that there is not even scum left.

The radar operator stared at the 4 light points that were constantly approaching in the interface, and repeated the parameters in his mouth, the target signal was normal, and the missile signal was also normal, according to the displayed data, after another 6~7 seconds, the first missile would encounter contact with the target signal. At that time, the radar interface will be the same as during the exercise, and there will be a phenomenon of "heavenly maidens scattering flowers" - this is the symbol of hitting the target.

5 seconds;

4 seconds;

3 seconds;

While all the officers and men were holding their breath and waiting for the good news, the radar operator suddenly let out an exclamation.

"It's ...... Enemy forces deploy ECM (Electronic Jamming)!!"

"What? Oops!!"

Major Heinrich, who came to his senses, hurriedly ordered the ECCM (Counter-Electronic Jamming) to be turned on, but by this time it was already too late, and the missile exploded in the air after passing with the target.

"How is that possible...... How could the Charlemagnes have an angle to deceive the answering jammer!!!"

The Major slammed his fist into the map table, a roar of rage that nearly toppled the command room.

Major Heinrich, who was a radar soldier, immediately realized that his radar had been electronically interfered with when he saw the signal change on the radar operation interface, and the normal circular light point became an "apple core" with light on both sides and dark in the middle, and the azimuth angle and high and low angles of the radar could not be automatically tracked at the same time - this is the unique effect of the angle deception inquiry jamming device when it is activated. The guidance radar of the homing rocket is jammed, the received radar beam is delayed, and false signals are released to lure the three "waterfalls" away from the target.

"Immediately unfold ECCM! The jamming signal will be 0.3 seconds later than the real target echo signal, filter out all the lagging signals, and immediately prepare for the second wave of transmission!"

The Major's reflexes were correct and fast, and his men were trained and not slow to react. But the enemy's movements are one step faster.

"The enemy ship fired smoke grenades, and infrared observation, optical observation, and radar observation were all interfered with!"

"What the hell is this?!!

"This is the commander of the second battalion of anti-aircraft artillery, can we open fire?"

"Radar station, can't you lock on to the target yet?"

"Please, open fire, at least block the airspace with a barrage!"

There are all kinds of opinions circulating in the airwaves, and each one is very reasonable, and it can solve the problem to a certain extent. But because of this, the commander of the anti-aircraft artillery, Major General Ahle, fell into the hell of choice. For a moment, it was completely uncertain which plan could deal with the opponent in front of him, who was obviously beyond his knowledge.

Fortunately, there was another guy at the scene who took this chaos into account and came up with corresponding countermeasures.

"This is Colonel Parsifal, the commander of the detachment. Repeat, here is the commander of the detachment, Colonel Parsifal. Inform the ships of the 2nd Cruiser. ”

The usual lazy voice was full of confidence and enthusiasm at this moment, and at some point, His Excellency the Commander of the Detachment put aside the elegant and comfortable command seat, climbed onto the command platform, and sat cross-legged. I saw him holding the microphone and saying:

"As you can see, an enemy ship is coming at full speed as a target for the Iserlohn battery, and the fleet will be ready for battle. ”

There was a pause, and his eyes, glittering with a sly brilliance, rose slightly.

"The whole ship retreats!"
