"What?" Liu Huaidong jumped up, "Show me!" ”

The communications staff officer immediately handed over the tablet computer in his hand, and the computer screen was displaying a satellite map outside Xidan Harbor, on which more than 20 points of light representing the enemy army were constantly flickering.

Liu Huaidong pointed his finger and canceled the target designation, and the picture on the screen became an original satellite image, carefully distinguishing, there was a blurry shadow under each disappearing point of light.

Liu Huaidong raised his head suddenly: "Battle alert, order all units to prepare for battle; Command the fleet to be fully anti-submarine...... Is Lu Airlines back? ”

"Not yet."

"Order the ground aviation to return as soon as possible, and order the ground crew to prepare anti-submarine equipment; Ask for the help of the Qionghe! ”

"Yes!" The communications staff officer immediately conveyed the order, and the mournful siren sounded in the sky again.

The Navy warships docked at the pier reacted the fastest, and as soon as they received the order, a destroyer launched anti-submarine rockets at the sea in the distance, and in the sound of breaking through the air, all twelve anti-submarine rockets flew towards the predetermined area.

The other warships were not slow to react, and they launched anti-submarine rockets at their respective targets, but in a few seconds, the rockets had already fallen into the water and quickly sank underwater.

The ships ran out of anti-submarine rockets and immediately reloaded them as fast as they could, but before the loading was finished, the deep bombs that entered the water had already exploded in the water, and the water columns jumped out of the water one after another.

And that's not all, the warships that were originally leaning on the dock started their engines and sailed away from the dock along a safe route.

Several frigates had a relatively shallow draft, and the positions of the mines were relatively deep, and the bottom of the ship could not touch the mines at all, so they simply drove directly above the mines, rushed to the vicinity of the alien submarine at the highest combat speed, and immediately activated the deep bomb launchers on the ship, and one after another threw the depth charges into the sky, crossing an arc and falling into the water.

Soon after, the deep bombs exploded one after another at different depths, and columns of water followed the battleship one after another, as if something in the water had been following the battleship.

Depth charges are not an advanced weapon, they must be dropped by warships, they are not very accurate, powerful and ranged, and once they are used, they mean that the enemy's submarines are already close to the fleet.

Take the anti-submarine rocket as an example, the maximum range of this thing is only about ten kilometers, and the most advanced torpedoes have a range of up to one hundred and forty kilometers!

The target of the deep bomb is the submarine, but the deep bomb with the rocket is a short arm, and it is impossible to reach the submarine at all. Conversely, a submarine can launch torpedoes at enemy ships at a distance of tens or even hundreds of kilometers.

In other words, the role of deep bombs in anti-submarine is very limited, and as of the war, the main function of deep bombs is no longer anti-submarine, but to intercept underwater torpedoes!

Due to the increasingly inconergious effect of depth bombs, some countries had eliminated this weapon before the war, and anti-submarine aircraft and anti-submarine torpedoes were used to carry out the execution against enemy submarines.

There are many disadvantages of deep bombs, but the biggest advantage of this thing is that it is cheap, and at present, the space fleet is the key development direction of various countries, and the navy's funds have been repeatedly compressed, and this old but economical weapon has to be reactivated.

If it weren't for that, there wouldn't have been so many deep bombs on these ships.

Of course, there are not only anti-submarine weapons such as deep bombs on battleships, but also anti-submarine missiles with a certain degree of mathematics, and the vertical launch systems on those frigates have not been idle, and one missile after another has been launched vertically into the air, and after turning a corner in the air, they plunged headlong into the water and released anti-submarine torpedoes.

The attack of the corvette at any cost should have achieved some results, but even if the alien submarine was hit by deep shells and torpedoes, it would not surface, and no one knows what kind of results were achieved.

The two destroyers were only one step slower than the frigates, but the destroyers were larger in tonnage and equipped with more weapons, and after arriving at the sea area where the incident occurred, deep bombs and anti-submarine missiles were thrown around as if they were not paying for money.

Don't look at the battle in front of you, but anyone with a discerning eye knows that the battleship is not the main anti-submarine force, and the real killer feature is the anti-submarine helicopter that has just taken off from the aircraft carrier.

To put it bluntly, the actions of the battleships were only to buy time for anti-submarine helicopters, and not to count on how many enemy ships to destroy with depth charges.

Several helicopters soon flew over the alien submarine, methodically released sonar, and after determining the position of the enemy boat, the helicopter released anti-submarine torpedoes into the water.

It's a pity that the alien submarines are too scattered, and it's not worth bombing with a nuclear bomb, otherwise Liu Huaidong would have bombed the nuclear bomb a long time ago.

It was probably the anti-submarine weapons that took turns to make the alien submarine feel the pressure, and several shadows under the water suddenly began to rise, and it can be seen on the satellite images that these shadows are becoming clearer and clearer.

The command immediately issued a warning, and at the same time, the battleships in front also noticed this unusual sign and immediately fired anti-submarine rockets at these positions - coincidentally, the anti-submarine rockets on several battleships had just been loaded!

The deep bombs that fell into the water exploded one after another, but the shadows under the water had nothing to do, and they still slowly floated up on their own.

Liu Huaidong witnessed this scene, his pupils couldn't help but shrink, and he was about to give an order, when one of the shadows had surfaced, but only a very small corner came out of the water, and it was not possible to see how big this corner was from the satellite map, so he could only determine that the main body of the enemy ship was still hidden underwater.

But the scene was different, the officers and men on the battleship and helicopter found that the radius from east to west was only three or five meters, like a snorkel sticking out of the water.

No one knew what it was for, but everyone knew that there must be some kind of danger hidden in it.

Several battleships immediately turned their guns, and the guns fired frantically at the snorkel.

Most of the shells landed on the water near the snorkels, and only a few hit the target, but after the smoke of the explosion cleared, there was no other effect than a rippling ripple.

Everyone couldn't help but be secretly surprised, the alien submarine was so strong? If that's the case, wouldn't all the deep bullets thrown before be useless?

At this time, several other effects under the water also surfaced, and five or six horns just broke through the water, and then the tips of those horns suddenly opened, revealing a hole in a black hole.

Before everyone could react, a group of servants had already flown out with their wings.

Everyone suddenly realized, what kind of horn is this, it is obviously the channel for aliens to release their servants!

Didn't say it, hit!

Several anti-submarine helicopters immediately pulled up, but the servants were much more agile than the helicopters, and they quickly caught up, and with a flash of silk, the fragile helicopters disintegrated on the spot and fell to the surface of the sea piece by piece.

Without exception, the crew of the helicopter were all killed on the spot, and the sea was stained red with blood.
