Submarines have been one of the most feared weapons in naval warfare since their inception.

It's not because of how powerful its firepower is, but because its trajectory has always been hidden under the sea, coming and going without a trace, and it's hard to guard against.

To ensure sea power, the development of search technology for submarines is an essential key.

Whether it is the United States, the Maoxiong in the north, or Huaguo, they have invested a lot of money and manpower in the research of this technology.

However, with the current level of science and technology on the earth, it is still not interesting, and this goal cannot be fully achieved for the time being.

Simply put, the movement of the submarine can only be explored through underwater sonar, and there are certain restrictions. For example, when the submarine is in a standby state with the engine turned off, even if the performance of the sonar is good, it is difficult to detect its existence.

And want to search for submarines from above the surface through radar signals...

Unless the submarine floated up to a depth of only ten meters from the water surface, and stretched out the snorkel to take a breath, otherwise, the radar would be of no use at all.

This is the reason why Nick Fury is satisfied—after installing the device that Coulson and his party brought back from Xandar to the radar of the Helicarrier, its performance has undergone earth-shaking changes. The tone has been raised to the level of 'Even at an altitude of more than 3,000 meters, the submarine located hundreds of meters below the sea surface can be directly monitored'.

If the original radar is compared to a pair of eyes, then the wide sea is a fog blocking the front of the field of vision, but now, with the addition of a new device brought back by aliens, these eyes are equal to an extra ability to see through... Although it may not be useful now, the strategic significance brought about by this promotion is not trivial, and it belongs to the kind that anyone with a little brain can see the weight.

"Sir, there is news from the navy."

"Yes, what did they say?"

"There is no problem with the results we detected. The target is the second-generation thresher shark. According to the navy's response, they are currently conducting deep-diving training at a depth of about 500 meters."

"Very good." The result was confirmed, and Nick Fury felt even happier. A faint smile unconsciously appeared on his normally serious black face.

Of course, the inspection of new equipment has to continue, not to say that it can end directly after finding a trace of a submarine.

Wanting to verify whether the function of this instrument would be compromised in extreme environments, Nick Fury's only remaining one-eyed eye slipped around twice, and issued a new order: "Turn the course, go to the North Pole lock up."

Compared with the United States, Mao Xiong pays more attention to the control of the waters near the Arctic.

Born in the army, he has a deep understanding of the thinking of the bears. Nick Fury is very sure that there must be submarines of the bears operating in the waters near the North Pole.

"Go to the Arctic Circle? Are you looking for Mao Xiongguo's submarine?"

"Well." Nick Fury nodded and looked at Maria Hill with a smile: "Don't get me wrong, I don't plan to do anything. I just want to go to the North Pole to verify that the new device works in a low-temperature environment." The performance is very low. It happens that there are Maoxiongguo’s submarines over there, so by the way, let them make a guest search for the target.”

"Do I need to report to the council?"

Although she is serving in S.H.I.E.L.D., Maria Hill's origins are not the same as Nick Fury's.

She came to S.H.I.E.L.D. as a deputy director after being appointed by the Council of Five Standing Committees. To put it bluntly, she is an airborne leader who came from outside. Unlike Nick Fury, she was originally an agent in S.H.I.E.L.D., and then she went through the internal promotion route step by step and was promoted to the director level.

Cannibalism is a matter of loyalty. As the management appointed by the Five Standing Council, Maria Hill is very concerned about the interests of the council. If the actions of SHIELD will harm the interests of the council or one of the countries, she will definitely stand up and propose be opposed to.

Including the current suggestion to avoid misunderstanding is also one of her responsibilities.

"No, the other party won't notice our actions anyway." Nick Fury waved his hand: "You can leave a record, but I don't think that thing should be useful, and no one will ask about it."

"...Okay." After thinking about it, Maria Hill nodded and didn't insist on her own opinion.

The flying speed of the space carrier is not as fast as that of an airplane, but it is more than twice as fast as the speed of sailing on the water.

About two hours later, the huge space carrier had already crossed over the Bering Strait and came to the arctic waters near Maoxiong Country.

While starting the radar to search for traces of submarines in the sea below, they advanced along the coastline. During the next three-hour cruise, the newly installed device on the aircraft carrier found traces of five submarines in turn. .

Although three of them docked on the shore, they couldn't be included in the score~lightnovelpub.net~ But such a result already made Nick Fury quite satisfied.

You must know that the submarines currently equipped by the U.S. military have a maximum dive depth of only 610 meters, while the submarines made by the bears are not only more durable, but also have a limit dive depth that is more than double that of U.S. submarines. up 1250 meters.

The two traveling Maoxiong submarines discovered by the aerospace carrier in the Arctic waters have dive depths of 650 meters and 700 meters respectively.

what does that mean? Although only two targets were found in total, because the detection depth is deeper...just from the effect of the test device, it is still very meaningful.

"Raise the sailing altitude to 5,000 meters and turn to the inland direction."

"Huh? Director, this is not appropriate."

"It's just an excuse. My destination is the Mediterranean." Turning his head to look at Maria Hill, Nick Fury shrugged: "It's a bit far to go back from this position. Compared to Next, cross the continent to land in the Mediterranean Sea, and the journey will be a little closer. Well, there is actually a small situation there, and I plan to take a look at it along the way."

"..."

"Don't worry, I know the seriousness." Looking at Maria Hill with a suspicious expression, Nick Fury shrugged: "It's just a radar, not a defensive shield. The new headquarters downstairs The burrito shop that opened was pretty good, I can't get enough of it. Get the nerves of a bear and get them shot down with missiles? You know me, I'm not such a cutie."

"...Okay." Seeing what Nick Fury said, Maria Hill could only smile wryly and shook her head: "I will record this matter in the memo, don't you mind?"

"That's your job." Nick Fury shrugged and smiled indifferently.
