Only when missiles can be launched underwater can submarines have practical operational significance. However, launching missiles underwater is much more difficult than on land. However, when Han Guo modified the 099 submarine, they did not encounter it. It’s a big problem, because the technical principles of underwater launching of ballistic missiles and underwater launching of cruise missiles are the same. Now that Han has overcome the difficulty of launching underwater ballistic missiles, there is no problem with launching cruise missiles underwater. Up.

Second, the launch tube on the 099 submarine was originally designed to meet the needs of underwater launching, so there was no waste of effort when modifying it.

"Open the launch cover." As the orders continued to descend, the underwater launch also entered the countdown.

On the side of the huge body of the 099 submarine, the lid of a silo was opened. Underneath, there was a thin sealing film to ensure that sea water would not be poured in.

At this time, on the sea, the red sun in the east is slowly rising from the sea, sprinkling the golden light onto the blue sea, and the sea is full of red light, which looks very spectacular.

"Attention, a three-minute countdown."

"One minute countdown."

"Ten, nine, eight." The countdown launch program came from a science fiction novel, but because it fits the actual situation, it was later adopted, which can create a sense of tension.

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

"Boom!" The sound of compressed air hitting the launch tube instantly spread to the entire submarine.

There is a special plan for launching missiles underwater. Now, the compressed air flows to the launch tube, pushing the missile, the missile's body, drilling forward, impacting and opening the fragile launch cover in front, and the sea is surging. Flowing into the launch tube, at the same time, the missile has been drilled out!

The body of the missile is eight meters long, and with the booster behind it, it is close to ten meters. This missile displaces the water and tilts upward.

This is also different from launching a ballistic missile. The launch tube of a ballistic missile is vertical. When going out, it also goes out vertically. This allows the missile to stay in the water for the shortest time and reduces the resistance of the water flow.

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

In order for these missiles to be installed normally, the vertical launch tube must be tilted. This angle is not small, it is a full forty-five degrees!

Therefore, the missile was tilted out in this way. When the missiles were all drilled out, the bubbles behind them overflowed, forming a huge cavitation.

Under this recoil force, even if the displacement is close to 20,000 tons, the 099 submarine cannot withstand this recoil force. The hull begins to move backward and downward, causing waves of spray. At this time, all officers and soldiers in the submarine, They all held onto the handrails tightly, they were already well trained.

The missile rushed forward, and finally, the missile came out!

When the missile drilled out, the short wing in the middle of the missile body began to stretch, like a small airplane, and then the booster behind the missile body began to ignite.

At this time, the entire missile is tilted forty-five degrees, the same as the posture when it was launched. A fiery flame emerged from the tail of the missile body. When the missile came out of the water, its speed was already very low, just like a flying fish leaping out. Generally, it is about to reach the highest point of flight, under the action of this thrust, the missile starts to accelerate again!

The flames shining on the sea, it looked so magnificent and beautiful. On the scientific research ship in the distance, the lenses of countless cameras flashed creakingly.

When Han was about to launch cruise missiles underwater, many people on the scientific research ship were moved. They asked for a long-distance appreciation. After careful consideration by Han, they agreed. So, after an hour of sailing, They came to the sea area where the submarine will launch the missile, and now they have captured the shot of the missile coming out of the water!

This action of watering out is so beautiful!

The Han country actually already has this kind of missile, which is incredible.

So, what kind of submarine is the submarine below?

They won't know, this kind of submarine will never show up from beginning to end.

The missile’s booster was burning rapidly, pushing the missile to a speed of Mach 0.85. At this time, the trajectory of the missile had also been flattened, and the distance from the sea surface was about 50 meters. Disappeared from his sight.

Then, the booster at the tail dropped, and the turbojet-6 engine behind was ignited. When the signal for its ignition was sent out, the 099 class submarine was full of joy.

It is not considered a successful launch just after the water is released. It must wait until its jet engine is successfully ignited. At this time, it is considered to be a successful launch. Whether it can hit the target or not is not their responsibility.

"Attention, dive down to fifty meters, double cars, go forward two, we will return." The captain gave the order.

The 099 submarine that completed the launch mission is like a shark underwater. After showing its fangs, it quietly left the launch position, leaving only the missile flying at low altitude.

This is not the first time that the Long Sword Ten missile has been launched. It has been launched on the ground several times before. Now the missile body is cruising smoothly.

Although the wing of the missile is short, it has enough lift. By balancing its lift and gravity, it can stabilize the height, and let its thrust and drag offset to stabilize the speed. These basic flight problems are solved. The next one is navigation.

Cruise missiles rely on remote sensing technology. They need satellites in the sky to scan the ground and draw them into a digital map. This digital map is mainly at elevation. At this time, the small radar in front of the missile is constantly searching. With the previous ground conditions and the digital map, you can correct your heading.

Of course, the endless sea is flat, but the small islands passing by nearby can be used for correction. In the age without satellite positioning, cruise missiles flew like this, but only by numbers. In the case of a map, it can reach the level of ten meters, but now, with the addition of satellite positioning, the cruise missile can be accurate to the meter level.

So, with satellite positioning, is it possible to throw away other methods and just use satellite positioning? This is of course possible. Eagle Nation’s low-cost joint attack ammunition is to install GPS modules and operating devices on the bomb. However, this is not safe. What if the satellite positioning signal is interfered on the battlefield?
