In the submarine, it is day and night, and the clocks and watches used here are all in a twenty-four-hour system.

After reaching the predetermined sea area at an economic speed, the two submarines stayed quietly underwater, and at the same time, they released the long-wave radio antenna, waiting to receive instructions from the headquarters.

Until now, they didn't know what their target was. It was so close to the Iranian port of Chakhbahar, it was likely to be an Iranian warship. However, this port had been hit by a missile in the last long-range air strike, and there was no need to ambush again.

Another possible target is US warships. The US Navy has been looking for opportunities to enter the Persian Gulf. They are here guarding outside the Persian Gulf, which is likely to pose a threat to the possible actions of the US Navy.

The advantage of the submarine is here, it is a hidden underwater power!

However, the US Navy is very powerful. Not to mention the aircraft carrier formation on the sea, even the Los Angeles-class nuclear submarines underwater can easily find them.

Are you afraid? Mustafa shook his head, no! The Iraqi army is absolutely not afraid of any force, even the most powerful United States and the Soviet Union!

The United States supports Israel and makes mistakes on the Palestine issue. Although the relationship between Iraq and the United States is improving now, when thinking of their Palestinian compatriots, they will not have much favorable feelings for Americans.

After waiting for a day, Changbo Radio finally began to receive orders from the headquarters again.

Target: US freighter McCain. Time: 3:00 pm on July 23, Location: Ambushing waters, Mission: Injure the ship.

Seeing the order, the deputy captain was a little confused: "Can it be that the wrong one is sent? What we are going to attack is actually an American civilian ship?"

"No, we can't be wrong. We strictly implement the order!" said Mustafa.

In the current situation of submarines, they can only receive signals. If they send back signals for inquiries, they will expose their location, especially the US Navy ships on the Arabian Sea 200 nautical miles away. If they find radio signals, they may curiously dispatch anti-submarine aircraft to search. At that time, it will be troublesome to complete the task.

As soldiers, they must obey orders as their duty! They must believe that this order is correct and they must strictly execute the orders!

Regardless of whether the target is an Iranian ship, the US Navy, or the US cargo ship, as long as the above orders are issued, all they need to do is to execute it without fail!

Now, there are seven hours left before the attack is launched.

"For the last preparation, check whether the torpedo is intact," Mustafa said.

The main weapon used by submarines is torpedoes, and torpedoes are also a complex weapon. Just like launching missiles, they must be tested before use. Just a year ago, the Argentine Navy's 209-class submarine also launched several attacks, but each time it failed. The torpedoes they launched either did not hit the target or exploded, posing no threat to the British Expeditionary Force. On the contrary, the British Navy's nuclear submarine, two torpedoes, killed the only cruiser of the Argentine Navy.

If the Argentine Navy is strong, then the result of this battle between Britain and Argentina will likely be rewritten.

The Iraqi Navy would never make a similar mistake. They once again tested the torpedo in the torpedo compartment of the tr-1700 submarine.

On the sea, the cargo ship McCain is sailing on the route to Chah Bahar.

During the voyage, they were always very cautious along the way, but they found that their luck was very good.

Except for an Oman patrol ship flashing over the sea ten nautical miles, they were nervous, and there was no more threatening target, and their cargo ship attracted no attention.

Saudi Rear Admiral Taral was full of confidence. In the escort formation, he was the only one who knew the news from Iraq that they needed to appear at the right place at the right time. At the same time, the two salvage ships were also ready to set off in Oman.

In the escort formation, there are several European journalists who report on the current situation of their escort. Although this place is no longer a hot topic, it still has news value.

In the Basra Navy Command, they were all paying attention to the situation on the sea. Since the submarine needed to remain hidden, they could only send messages to the submarine, but the submarine could not return. Naval commander Nasser was a little nervous.

This time, you must not make mistakes! If the submarine does not attack the other party's cargo ship, or if the attack is wrong, their operation will be a failure.

The commander at the scene, the captains of the two submarines, Mustafa and Ismail, were not nervous, and they believed in their abilities.

After the last inspection of the torpedo, the submarine became quiet, with only sonar soldiers still meticulously monitoring the surrounding ships.

In order to avoid misattacks, they chose a location slightly away from the port of Chahbahar, where the two submarines set up an ambush on the same channel ten nautical miles apart.

The sonar soldiers could hear some sounds, which were emitted from the busiest Strait of Hormuz in the distance, and the target from the Gulf of Aden in the West had not yet appeared.

Time passes in a minute and a second.

When the submarine's watch pointed at 14:40, the sonar soldiers finally heard the suspicious target: twenty nautical miles, speed: twelve knots!

It was emitted by a large propeller for low-speed ships. In addition, the sound of the bow hitting the sea water should be emitted by a cargo ship with a displacement of about thousands of tons.

Hearing the target appeared, the crew on the submarine began to act.

"Go forward one, left rudder two, head and tail ballast tank drain, ready to rise to the depth of the periscope," said Mustafa.

Using a periscope to observe the target and then install data for the torpedo. It was only in the early days when submarines were used. Nowadays, torpedoes mainly use sonar to detect the navigation data of enemy ships and provide them with torpedoes.

However, what is attacking now is not warships, but ordinary civilian ships. In order to hit the wrong target, you must ensure that the target you are attacking is not wrong.

How to confirm?

The sonar system used by submarines has installed the sound signals of most warships in the world in advance. After the sonar is discovered, in addition to relying on the ears of sonars, it can also be analyzed and compared with computers. However, the system capacity is now limited, and it can only install the sound signals of major warships in the world. Civilian ships like this are absolutely out of range.

Therefore, the only way to confirm the goal is to observe with your eyes!

Because the submarine is almost stationary on the seabed, if the submarine is only operated to operate the submarine to float, the submarine needs to slowly accelerate and gradually float up, which is a long time.

Directly draining the water in the ballast water tank is a way to float quickly. The buoyancy is greater than the gravity. Even if the submarine is not activated, it will surface.

Seeing the depth of the submarine gradually decrease, when it was still twenty meters away from the sea, Mustafa let the submarine inject water again to balance the hull. Otherwise, if it floats up again, it will surface.

After this period of training, the submarine soldiers have mastered the operating steps completely. Under their operation, the 2,000-ton submarine swams with huge bodies in the water, and when it is still twelve meters away from the sea, it has resumed its submarine posture.

"Periscope."

On the submarine command tower, a thick pipe rose up and gradually exposed the sea.

At this time, the clock pointed to fourteen fifty minutes.

"Sonar signal, fifteen degrees on the port side, fifteen nautical miles away."

Listening to the sonar's report, Mustafa turned the periscope to the fifteenth degree position on the port side.

In the cross-sight line of the periscope, below is the rippling sea water, above it is an endless sky, the sea is empty and there is nothing.

Mustafa knew that although the submarine's periscope was already a very complex and precise equipment, the search distance was not very far. It was likely that the periscope could not be seen at a distance of fifteen nautical miles.

Gradually, in the narrow field of view of the periscope, a ship blazing black smoke appeared, a large cargo ship using low-speed marine diesel engines.

The goal finally appears!

Advance two, right three, ready to occupy the attack position," Mustafa said.

The tr-1700 submarine skillfully began to seize the launch position.

While the submarine is accelerating, the horizon in the periscope begins to blur. When using the periscope, it will cause additional drag and will cause the periscope's barrel to shake slightly, so the speed cannot exceed eight knots.

However, in order to occupy the launch position as soon as possible and maneuver quickly, it is also necessary. If it cannot move to the appropriate position as soon as possible underwater, it will cause the submarine to be very passive and sometimes even lose the launch opportunity.

Fortunately, the other party was a slow cargo ship.

The submarine underwater began to accelerate and began to move towards the starboard position of the USS McCain cargo ship.

In Mustafa's vision, the outline of the ship became clearer and clearer. The bow of the hull and the appearance of the hull were indeed the target they were looking for: the McCain!

"Prepare, install the No. 1 launch tube." Mustafa said.

This time, it was a complete live-fire shooting.

The officers and soldiers in the torpedo compartment began to load the 533 mm caliber Sut torpedo into the launch tube.

During World War II, all these tasks were done by strong men and were completely physically labored. Now, there is basically no need for human physical labor, and the torpedo has been loaded into the launch tube.

Although the tr-1700 only has six torpedo tubes, due to its high degree of automation, the launch speed is even higher than that of other submarines with eight torpedo tubes.
