It is not easy to find a shipwreck at the bottom of the sea, and many times it is a fluke. And now, it is even more difficult to find an aircraft from the bottom of the sea, which is far smaller than a ship.

The two survey ships are going hand in hand, combing this sea area like a comb, trying to find out the MiG-25 fighters on the bottom of the sea, maybe they will have a harvest in the next minute, maybe they will have to wait for a few days, or even a month or two.

On the survey ship, the busiest are the people in the sonar room, because the way of this detection is to search through the active sonar emitting ultrasonic waves to the bottom of the sea, they wear headphones and listen carefully.

Sonars are a special group of people who have keen hearing, and can tell from sonar whether a distant fish is spitting bubbles or the propeller of a ship, and they can determine what kind of vessel it is.

Compared with the busy survey ship, the salvage ship is now idle, and the Americans on board are standing on the deck, basking in the sun and blowing the sea breeze, chatting with each other.

Behind them were two American warships, a Keeling-class destroyer and a Knox-class frigate, which had been launched from the port of Yokosuka after discovering that the Soviets had dispatched reconnaissance planes to reconnoiter the salvage formation.

Among them, the Keeling-class has a displacement of nearly 4,000 tons, and it is a warship built in the late stage of World War II, which has long been old and belongs to the model that is about to be decommissioned.

The Knox-class frigate is the first warship to enter active service in 65 years, and the last warship of the same type was entered service in 74 years, belonging to the second generation of anti-submarine frigates of the United States, with relatively advanced equipment, and the anti-ship side has a quadruple Harpoon ship missile and L 127 mm guns. In terms of anti-submarine operations, there are L eight-pack Asloc anti-submarine rockets and L twin-mounted MK-32 torpedo tubes, and L anti-submarine helicopters are also on board. As for air defense, it also has Sea Sparrow anti-aircraft missiles, which can be regarded as exhaustive. Although it is called a frigate, its displacement is already close to 4,000 tons, which is the same as that of the Keeling class.

To say that it is backward, that is, the frigate also uses a steam turbine as the power, and the backward boiler is smoking at this time.

At this time, the Knox-class frigate Donard B. Peary was sailing at the back of the formation, and the captain, Major Davis, was standing on the bridge looking ahead, somewhat impatient with this nanny mission.

It was only a hundred nautical miles from its own coastline, and the fighter planes could fly there in ten minutes, and although the Soviets conducted reconnaissance, as long as their brains did not enter the water, they should only be confined to reconnaissance.

Did the Soviets dare to come and look for trouble? On their own one-third of an acre of land, if the Soviets really dared to come over, it would be simply...

"Report, radar found three echoes on the surface of the sea." At this moment, a report came from the radar room: "In the direction of nine o'clock, at a distance of twenty-five nautical miles. ”

"Don't worry, it's definitely a fishing boat." Major Davis said, picking up the binoculars.

Due to the influence of the curvature of the earth, the most advanced shipborne radar can search the sea at a distance of no more than 40 kilometers, and although many anti-ship missiles have a range of more than 100 kilometers, they also need carrier-based helicopters and other equipment to guide them in the middle. However, the modern-level bandstation radar introduced by Huaxia in later generations can reach more than 100 kilometers, but it is based on the principle of atmospheric waveguide, and the distance is reached, but the accuracy is very poor.

In the distance, there was black smoke from the chimney, then the mast, and Major Davis was a little strange, not like a fishing boat?

Continue to magnify, and finally see clearly, it's a salvage ship? What's going on? Are you here to help with the salvage? Why didn't I get the notification above?

The ship became clearer and clearer, and at the same time, the ships behind it also appeared in view.

Chimneys, masts ... When he saw the flag on the mast, Davis was a little puzzled, it should be a warship, and the flag was still red, and the direction was from the west.

As the other party continued to get closer, he could finally see the outline clearly, and Major Davis was suddenly shocked, that flag was the flag of a sickle and an axe! It's the naval ships of the Soviets!

What did the Soviets come for? Major Davis immediately shouted: "Attention, the warship of the Soviets has been spotted!" Full rudder left, advance three, ready to fight! ”

Who knows what the Soviets came to do! The other party is already 100 nautical miles away from your own coastline! As Major Davis gave the battle order, even thicker black smoke rose from the chimney, and the frigate accelerated with a buzzing sound.

The Harpoon missiles have also begun to warm up, and once they find that the Soviets are going to use force, they can strike back as soon as possible.

"Send a flag and tell them that this is the territorial waters of the island country, and let them retreat." Major Davis pressed the intercom switch and spoke to the signalman on the mast.

The two sides gradually approached, and Major Davis could visually observe that the two Soviet warships coming across were old Riga-class frigates. Such frigates, with a displacement of less than 1500 tons, do not have missiles in their armament, mainly three 100 naval guns and 37 and 25 naval guns, as well as 533 torpedo tubes and anti-submarine rockets.

The Riga class is the name of NATO, the Soviets have a Type 50 model, that is, a frigate that began to be built in the 50s, and the Pacific Fleet is equipped with a total of 11 ships.

What did the Soviets send such old-fashioned frigates for? Is it to provoke the sea power of the United States? The Soviets weren't crazy, were they?

"Report, they replied, this is the public waters." The Bannerman shouted through the intercom.

Public seas? Major Davis was stunned for a moment, as if what the other party said was right, even the United States only agreed to the territorial waters of twelve nautical miles, and used this as an excuse to take advantage of the naval superiority of the United States to approach any hostile country at will.

"Let them go, don't interfere with our work." Major Davis said.

No matter what the purpose of these people is, in short, since they are two old warships, they are definitely not here to fight.

"Report, the Americans want us to leave and not interfere with their operations." Ten nautical miles away, seeing the lights and flags of the other side, the lookout on the Soviet Riga-class frigate Tashkent, said to the captain.

The Americans are really cautious! Captain Ilyich said: "Send them a signal that we are about to start a salvage operation, please do not interfere with our operations!" ”

When he set off, he accepted this mission, and Captain Ilyich felt a great responsibility, and this time, even if he could never go back, he had to complete the mission!
