Super Weapon Swap System

Submarines have practical operational significance only if they can launch missiles underwater. However, launching missiles underwater is much more difficult than on land. However, Han did not encounter much problems when refitting 099 submarines, because the technical principle of launching ballistic missiles underwater is similar to that of launching cruise missiles underwater, Now that Han has overcome the difficulty of launching ballistic missiles underwater, there is no problem with launching cruise missiles underwater.

Second, the launch tube on the 099 submarine was originally designed to meet the needs of underwater launch, so it didn't waste much effort when refitting.

"Open the launch cover." with the orders issued one by one, the underwater launch also entered the countdown.

On the side of the huge body of the 099 submarine, the cover of a launching well was opened, and below it, there was a thin sealing film to ensure that the sea water would not be poured in.

At this time, on the sea, the red sun in the East is rising slowly from the sea, sprinkling the golden light on the blue sea. There is a red light on the sea, which looks very spectacular.

"Attention, three minutes countdown."

"One minute countdown."

"Ten, nine, eight." the countdown launch procedure came from a science fiction novel, but it was later adopted because it was very in line with the actual situation, which can create a sense of tension.

"Launch!" when the count reached zero, the officer in charge pressed his hand on the launch button.

"Bang!" the sound of compressed air hitting the launch tube spread to the whole submarine in an instant.

There must be a special scheme for launching missiles underwater. Now, the compressed air flows to the launch tube, pushing the missile. The missile body drills forward, impacts and opens the fragile launch cover in front, and the sea water flows into the launch tube. At the same time, the missile has drilled out!

The missile's body is eight meters long. With the booster behind it, it is close to ten meters. This missile pushes aside the water flow and tilts upward.

This is also different from launching ballistic missiles. The launch tube of ballistic missiles is vertical. When they go out, they also go out vertically. This can minimize the time of missiles in the water and reduce the resistance of water flow.

But the 099 class submarine was not, because its shell diameter was limited, and the p-700 missile was not specially built for it at that time. Therefore, when it was installed, if it was installed vertically, it had to bulge a turtle back.

In order for these missiles to be installed normally, it is necessary to tilt the vertical launch tube. This angle is not small, it is a full 45 degrees!

Therefore, the missile goes out obliquely. When all the missiles are drilled out, the bubbles behind overflow outward, forming a huge bubble.

Under this recoil force, even if the displacement is close to 20000 tons, the 099 submarine can not resist this recoil force. The hull began to move towards the rear and lower part, causing bursts of spray. At this time, all the officers and soldiers in the submarine firmly grasp the handrail, and they have been trained well.

The missile rushed forward. Finally, the missile came out!

When the missile drilled out, the short wing in the middle of the missile began to extend, just like a small plane. Then, the booster behind the missile began to ignite.

At this time, the whole missile is tilted 45 degrees. Like the attitude at the time of launch, there is a hot tongue at the tail of the missile. When the missile comes out of the water, the speed is very small, just like a flying fish jumping out, and it is about to reach the highest point of flight. Under the action of this pushing force, the missile begins to accelerate again!

The flame shines on the sea. It looks so spectacular and beautiful. On the distant scientific research ship, the lenses of countless cameras flicker.

When the state of Han wanted to launch cruise missiles underwater, many people on the scientific research ship were moved. They asked to enjoy them from a long distance. After careful consideration of the state of Han, they agreed. Therefore, after an hour of navigation, they came to the predetermined sea area where submarines launched missiles. Now, sure enough, they caught the scene of missiles coming out of the water!

This water movement is so beautiful!

It's incredible that the state of Han already has this kind of missile.

So, what is the submarine below?

They won't know. This submarine won't show up from beginning to end.

The booster of the missile is burning rapidly, pushing the missile to Mach 0.85. At this time, the trajectory of the missile has flattened, about 50 meters from the sea. At this time, it has disappeared from the sight of who.

Then, the rear booster fell, and the turbojet-6 engine behind ignited. When the signal of ignition was sent, there was jubilation on the 099 submarine.

Just out of the water, it is not a successful launch. They must wait until its jet engine is ignited successfully. At this time, it is really a successful launch. Whether they can hit the target or not is not their business.

"Attention, dive to 50 meters, double cars, advance two, we return." the captain gave an order.

The 099 submarine that completed the launch mission was like an underwater shark. After exposing its fangs, it quietly left the launch position, leaving only the missile flying in low air.

This is not the first launch of the long sword 10 missile. It has been launched on the ground several times before. Now, the missile body cruises smoothly.

Although the wing is very short, it already has enough lift. If its lift and gravity are balanced, it can stabilize the altitude, and if its thrust and resistance are offset, it can stabilize the speed. These basic problems of flight are solved, and the rest is navigation.

Cruise missiles rely on remote sensing technology. They need satellites in the sky to scan the ground and draw it into a digital map. This digital map is mainly elevation. At this time, the small radar in front of the missile is also constantly searching for the ground conditions in front of it. By cooperating with the digital map, they can correct their course.

Of course, the vast sea is flat, but the small islands passing nearby can be used to correct. In the era of no satellite positioning, cruise missiles flew like this, but they can reach the level of 10 meters only by relying on digital maps. Now, with satellite positioning, To make the cruise missile accurate to the meter level.

So, with satellite positioning, can we throw away other means and only use satellite positioning? Of course, this is possible. The eagle's low-cost joint attack ammunition is to install GPS modules and operating devices on the bomb. However, this thing is not safe. What if the satellite positioning signal is disturbed on the battlefield?
