"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. Like launching missiles, they must be tested before use. Several attacks were carried out, but each time they failed. The torpedoes they launched either missed the target or did not explode, and did not pose any threat to the British Expeditionary Force. On the contrary, the nuclear submarines of the British Navy, two torpedoes Killed the only cruiser of the Argentine Navy.

If the Argentine navy is strong, then the outcome of this battle between Britain and Argentina is likely to be rewritten.

The Iraqi Navy will never make similar mistakes. In the bow torpedo compartment of the TR-1700 submarine, they tested the torpedo again.

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

During the voyage, they have been very cautious all the way down, but they found that their luck was very good.

Except for an Omani patrol boat flashing past the sea ten nautical miles away, which made them nervous, other than that, there were no threatening targets anymore, and their cargo ship did not attract any attention.

Rear Admiral Talal of the Saudi Navy is full of confidence. In the escort formation, he is the only one who knows the news from the Iraqi side. They need to appear at the right place at the right time. At the same time, the two salvage ships are also ready in Oman Ready to go.

In the escort formation, there are also several European reporters reporting on the status of their escort. Although this place is no longer a hot spot, it is still newsworthy.

In the Basra Naval 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. Nasser, the naval commander, was a little nervous.

This time, there must be no mistakes!If the submarine did not attack the opponent's cargo ship, or if the attack was wrong, their operation this time would be considered a failure.

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

After checking the torpedo for the last time, the submarine became quiet, only the sonar soldiers were still meticulously monitoring the surrounding ships.

In order to avoid misfires, they chose a location slightly away from Chah Bahar Port. The two submarines were separated by ten nautical miles and set up an ambush on the same channel.

The sonar soldiers could hear some sounds, which were coming from the busiest channel in the Strait of Hormuz in the distance, but the target coming from the western Gulf of Aden had not yet appeared.

Time passed in a minute and a second.

When the hands of the submarine pointed to [-]:[-], the sonar crew finally heard the suspicious target: twenty nautical miles, speed: twelve knots!

It was made by a large propeller used by a low-speed ship, coupled with the sound of the bow hitting the sea, it should be made by a cargo ship with a displacement of about several thousand tons.

Hearing the appearance of the target, the crew on the submarine began to act.

"Foreward one, left rudder two, the fore and aft ballast tanks are drained, ready to ascend to the depth of the periscope." Mustafa said.

Using the periscope to observe the target, and then setting the data to the torpedo, is just the way used in the early submarines. The current torpedo mainly uses sonar to detect the navigation data of the enemy ship and provide it to the torpedo.

However, what is being attacked now is not a warship, but an ordinary civilian ship. In order to hit the wrong target in a way, you must ensure that the target you are attacking is correct.

How to confirm?

The sonar system used by submarines has already installed the sound signals of most warships in the world in advance. After the sonar is found, in addition to relying on the ears of the sonar operator, it can also be analyzed and compared with a computer.However, the current system capacity is limited, and it can only be equipped with the sound signals of major warships in the world. Civilian ships like this are definitely not within the scope.

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

Because the submarine is almost at rest on the bottom of the sea, if only the horizontal rudder surface is used to operate the submarine to float up, the submarine needs to slowly accelerate and gradually float up, which takes a long time.

Directly draining the water in the ballast water tank is a way to quickly float up. The buoyancy is greater than gravity, and even if the submarine is not started, it will surface by itself.

Seeing that the depth of the submarine was gradually decreasing, when it was still 20 meters away from the sea surface, Mustafa refilled the submarine with water to balance the hull, otherwise, if it went up again, it would surface.

After this period of training, the submariners have fully mastered the operation steps. Under their operation, the 12-ton submarine, with its huge body swimming in the water, is [-] meters away from the sea. At that time, the submarine posture was restored.

"Raise the periscope."

On the submarine conning tower, a thick pipe rose up, gradually protruding from the sea.

At this time, the clock pointed to fourteen fifty.

"Sonar signal, fifteen degrees to port, fifteen nautical miles."

Listening to the sonar's report, Mustafa turned the periscope fifteen degrees to port.

In the crosshairs of the periscope, below is the rippling sea water, above is the endless sky, the sea is empty, nothing.

Mustafa knew that although the submarine's periscope was already a very complicated and sophisticated device, the search distance was not very far, and at a distance of fifteen nautical miles, the periscope might not be able to see it.

Gradually, in the narrow field of view of the periscope, a black-smoky ship appeared. It was a large cargo ship using a low-speed marine diesel engine.

The target finally appeared!

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

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

While the submarine was accelerating, the field of vision in the periscope began to blur. When using the periscope, it would cause additional resistance and cause the barrel of the periscope to vibrate slightly, so the speed could not exceed eight knots.

However, in order to occupy the launch position as soon as possible, it is also necessary to maneuver quickly. If the submarine cannot move to a suitable 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 submerged submarine began to accelerate and moved towards the starboard side of the cargo ship McCain.

In Mustafa's field of vision, the outline of the ship became more and more clear. The hull number on the bow and the shape of the hull were indeed the target they were looking for: the McCain!

"Get ready, the No. [-] launch tube is loaded." Mustafa said.

This time, it was a complete live ammunition shooting.

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

In World War II, all these jobs were done by strong young men, and they were all physical labor. Now, there is basically no need for physical labor, and the torpedo has already been loaded into the launch tube.

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

Chapter 499 Torpedo launch!

The main weapon used by submarines is the torpedo, and Germany has always attached great importance to the development of underwater power. During World War II, it developed the world's first electric torpedo and the world's first acoustic homing torpedo. After World War II, due to the German It is a defeated country, and can no longer develop thermal power torpedoes, but can only develop this kind of ordinary electric torpedoes. This leads to a gap between SUT torpedoes and large thermal power torpedoes such as MK48 and "Swordfish" in terms of basic performance data.However, the biggest advantage of this new export-only torpedo developed in 1980 is that it has very low noise.

"The torpedo has been loaded." In the torpedo cabin in front, the voice of the sailor's report came.

The SUT torpedo is an electric mine developed by Germany after years of research. It has three-dimensional maneuverability and can attack enemy surface ships and submarines. The SUT torpedo has a diameter of 533 mm, a total length of 6.15 meters, and a weight of 1414 kg. The maximum sailing depth is 400 meters, and the minimum sailing depth is 2 meters. It is powered by a silver-zinc battery and a double-rotating DC engine to drive a set of counter-rotating propellers.The torpedo warhead has a mass of 260 kilograms and is filled with TR8870 high-energy explosives mixed with TNT and RDX. One torpedo can sink a local ship of [-] tons.

Originally, this torpedo could use active sonar to provide data. However, in this case, active sonar needs to send sound waves to the target to make the other party aware.Therefore, Mustafa chose the ancient method: use the attack periscope to provide launch data visually!

"Target, one degree to starboard, distance, seven nautical miles, ready to launch."

It is a bit outdated for an advanced wire-guided torpedo to adopt this launching method, but this is a means to make this incident an accident, otherwise, the sound of the hull being hit by the attack sonar will be heard , they knew that it must be their own side that launched the torpedo.

"Data has been entered."

"Shoot!"

Under the sea where no one can see, the TR-1700 submarine has opened the launch cover of the head.The water pressure balance system starts to work, so that the rear of the torpedo to be launched has the same pressure as the outboard sea water, so that when the torpedo moves forward during the launch process, the seawater back pressure originally acting on the torpedo head is acted on the torpedo tail. The back pressure is offset, and then, with a bang, the compressed air in the high-pressure air bottle of the launching system enters the tail of the torpedo in the launch tube, and the compressed air entering the tail of the torpedo begins to expand, pushing the torpedo in front and the surrounding area of ​​the torpedo. A piece of sea water squeezed out the launch tube.
