A submarine, naturally, is a vehicle that sails underwater.

Therefore, according to their experience, it is almost impossible to accurately find this submarine in the vast sea.

But the submarine will eventually come to the surface.

As long as you keep an eye on the port, you can catch a rare trace of it when it floats up to load cargo.

Originally, the port was stationed with intelligence personnel for a long time, responsible for investigating the entry and exit of raw materials for the giant beast industry. But the submarine did not notify the port dispatch at all every time it entered the port, and even the factory staff was responsible for the entry and exit of materials.

The intelligence officers in the harbor had no access to information about the submarine at all.

Jia is not pretending to be a white jade for Tang Jin, and I am afraid that only the United States can come up with this kind of Shanghai-style trick in this world, specially changing the orbit of a reconnaissance satellite to keep an eye on the port.

Now they're burning money and paying in return.

Just in the morning, Tactical Commander Madix received the latest intelligence from the Pentagon.

Reconnaissance satellites captured an aerial view of the submarine.

In addition, reconnaissance satellites do not only have the reconnaissance function of optical shooting. As one of the world's most advanced reconnaissance satellites, in addition to carrying advanced optical equipment, it also optimizes the tracking ability of moving targets on the sea surface at any cost.

Multi-band, multispectral reconnaissance equipment.

Electromagnetic remote sensing equipment.

This allows the reconnaissance satellite to track the course based on the special wake generated by the propellers of large ships and even submarines while sailing.

The larger the ship, the greater the fluctuations in currents when navigating the surface.

This fluctuation of the current, caused by the propellers and the contours of the hull, can be seen dragging a long white wave mark on the surface of the sea, even if viewed with the naked eye.

And how much more so under sophisticated reconnaissance instruments?

Of course~

Because the submarine is sneaking in the sea, its propeller wake can only be caught by reconnaissance satellites in the shallow sea.

The kind of technology that is rumored on the Internet that satellites can pull submarines out of the vast deep sea based on the special wake transmitted by submarines to the sea surface in space is still an alien technology that human beings do not master.

Therefore, in this latest information, only when the submarine enters the port, a 20-kilometer-long navigation trajectory line is marked.

Farther away, the satellite, which has a strict observation window, will no longer be able to capture the characteristic ripples of the propellers.

Reconnaissance satellites have only an eight-minute observation window every day, and if they miss this time, the satellite will fly along the orbit to other places.

"That's enough!" Tactical Commander Madix clenched his fists and muttered to himself as he looked at the intelligence, "The trajectory of the twenty-kilometer route already allows us to preliminarily judge its sailing route. The next step is to pre-empt the route it may pass through, so that it will never have a second chance to enter the port. ”

"Just ......"

"Is this really a submarine?"

Looking at the satellite aerial view, Tactical Commander Madix was in a state of mystery.

The satellite aerial view has an accurate scale, and according to the scale data, the submarine in the photo with a dark body and strange silhouette does not look like a submarine at all.

The submarines are all teardrop-shaped or transitional, but this one can be seen in satellite photos. There is no outline of a submarine at all, but it is closer to the shape of a landing craft.

It also does not have the upper hull and rudder that a submarine should have.

Probably because it was already close to the port, the "submarine" in the picture, which did not look like a submarine, was completely adrift on the water like a ship, and entered the port at a speed of ten knots.

Of course, if it hadn't surfaced and docked, the reconnaissance equipment would not have been able to trace the 20-kilometer-long trajectory line so easily.

Tactical Commander Madix also consulted with submarine experts in the Pentagon.

As a result, the other party directly and confidently told him that this could not be a submarine at all.

Submarines are not designed to be teardrop-shaped, so what else is being built?

In satellite photos, the underwater resistance of a submarine is at least three times that of an ordinary submarine. After this triple drag is converted into the energy that the power system needs to cancel, it is a miracle that the submarine can run at a speed of five knots underwater.

What can it be if it's not a submarine?

Tactical Commander Madix and intelligence analysts still believe it is a submarine.

Because they had never captured the ship's radar feed, or even arranged a satellite, they couldn't even figure out whether the submarine was round or flat.

Perhaps Behemoth Industries designed it this way to allow the submarine to have a larger cargo capacity.

……

Whatever the purpose, as long as the submarine is hunted, all the mysteries will be solved.

As the commander of all operations against the Behemoth Industry, Madix certainly has the right to let the Fifth Fleet, which is closest to here, hunt down the submarine.

The second arrival of the reconnaissance satellite at the port would not be until the next morning, and in order to avoid long nights and dreams, Madix immediately began to contact the Fifth Fleet and asked them to arrange a "blockade line" on the route through which the submarine must pass.

The Fifth Fleet base is located in the Persian Gulf, while the Anu district is located in the Gulf of Guinea.

The two are separated by tens of thousands of nautical miles and straddle two oceans.

In order to accurately mark the course of this mysterious submarine on this endless ocean......

It's not that hard.

Because the results of the reconnaissance in the morning of eight minutes have clearly shown that the submarine is on a route from south to north, anchoring in the harbor along the coastline of the Gulf of Guinea.

When it returns, it must have followed the edge of the African continent, passed through the waters off South Africa, and finally sailed into the ocean from one of the seas on either side of Madagascar.

This route is the shortest and most economical route back to China.

Behemoth Industries will never take a detour of thousands of nautical miles to waste time transporting valuable supplies.

Madagascar, the fourth largest island in the world, is separated from the African continent by the sea, with less than 400 kilometres of straits in between. The route is the shortest, and it is also the only route for all civil ships traveling between two oceans.

Basically, as long as it is intercepted in this strait less than 400 kilometers wide, there is a 90% chance that it will intercept the mysterious submarine of the Behemoth Industry.

The other ten percent, left to the other side of the island of Madagascar.

If the submarine goes around Madix Island and takes the other side of the sea, it will only waste a few hundred nautical miles around the island.

Hundreds of nautical miles more is a waste of time and energy, but it is possible to avoid this busy strait. With the terrifying financial resources of Behemoth Industries, they probably wouldn't really care about this loss.

Therefore, Madix asked the Fifth Fleet to also arrange a 400-kilometer "blockade line" in this sea area.

Two 400-kilometer-long submarine hunting blockade lines are easy for the Fifth Fleet. It will take only two days at most to mobilize the military ships that are rushing to the nearby waters to deploy on both sides of Madagascar.

It takes time for the Behemoth Industries submarine to load and unload supplies, as does it for the return voyage to the island of Madagascar.

Then, two days later, this submarine hunting blockade, composed of the world's most powerful maritime military forces, will quietly wait for the arrival of this submarine.
