The submarine slowly approached Cape Canavera at a "turtle speed" of 3 knots underwater.

The early winter night came very early, and it didn't take long to get completely dark on the sea. When the submarine No. 1048 approached the outside of Tarapeg Port, it was already past nine o'clock in the evening.

The lights are on in Tarapege Harbor, and the freighters gathered in the port are brightly lit. The tall lighthouse standing at the entrance of the Cape Canavera channel is even more clearly visible to people more than ten nautical miles away.

The Japanese radio technology was not advanced. At this time, most warships were not equipped with sonar detection systems, and Chinese submarines could boldly conduct close-up reconnaissance. At this time, through the gaps in the atoll, it was clear that there were about 30 cargo ships parked in the port. The Japanese army stationed on Saipan had about one wing, and the navy was not strong, with only two destroyers and some patrol gunboats.

More than ten minutes later, Sa Shijun, who was sitting in front of the periscope, and Captain Lam Feng, discovered that a freighter had sailed out of the channel at almost the same time.

"A bulk cargo ship has a displacement of about 2,500 to 3,000 tons!" Sa Shijun has had nearly thirty years of naval experience, but he must not be able to quickly identify the tonnage of the ship in the periscope like a submarine commander.

"Are we going to attack it?" Sa Shijun asked.

"It's just a plate of appetizer, let other submarines deal with it, let's see if we can find opportunities to dive. "Long" ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖门 ↖�

"Why not use rocket launchers? The ships in the port are now on lights, with obvious targets, and they are all gathered near the dock. We only need to carry out a cover shelling on that area to cause enough damage to the enemy." Sa Shijun said, "When you sneak into the port and then want to withdraw, there is a great danger."

Lin Feng pondered for a moment, "Sir, you make sense, but we have never used that thing in actual combat, and we don't know how effective it can have."

"How can you know if you don't try it? This may invent a new submarine tactic." Sa Shijun encouraged that he also wanted to see how powerful these rocket launchers are. I heard that this thing is good when suppressing artillery fire in the army. However, the effectiveness of it can be at sea has not been specifically verified.

"One-half speed, turn to 90!" Lin Feng issued an order to retreat. Now the submarine is less than 5,000 meters away from the port, and he needs to retreat to a slightly safer distance.

About 20 minutes later, a loud bang came from the water far away, and it was obvious that the unprepared Japanese freighter was torpedoed by a Chinese submarine waiting outside. A fire lit up on the dark sea about six nautical miles away in the distance, like a paddling match stick in the periscope. About 7 minutes later, the sonar soldiers reported that they had caught the sound of three high-speed propellers and were rushing to the site of the accident at full speed.

It seems that the Japanese are responding very quickly.

"Sir, I think it's very suitable to be around 9,000 meters, so the hitting accuracy will be higher." Lin Feng no longer cared about the situation of those Japanese patrol boats and began to study shelling tactics on the nautical charts. This place turned out to be the German territory, so the Chinese Navy had detailed nautical charts.

"Well, I think we should test the current new tactics around 13,000 meters. How far can the periscope see after the submarines float to the sea?" Sa Shijun said. "If this tactic is successful, our submarines can approach the coast of Japan and attack their coastal cities and industrial facilities."

"The submarine's altitude is not enough. Only 16 nautical miles were observed during the day and only about 8 kilometers at night. The radar on the boat can detect targets, but cannot provide fire control data. However, there are lights in the port now, so there should be no problem with 13 kilometers." Lin Feng said.

"In the caliber of our artillery, the Japanese may think that they have been attacked by the heavy cruiser fleet. It can be imagined that tomorrow all the transport ships on this route will hide in the port, and their maritime transportation will be temporarily interrupted. And they will send a large number of aircraft warships to find the non-existent 'attack fleet' in this area." Sa Shijun said, "All new tactics can exert their maximum power at the beginning. Over time, the enemy will naturally find new ways to deal with it."

The Japanese continued to search at the location where the freighter was in trouble, and the attacking Chinese submarines had already evacuated. After a while, two destroyers stationed in the port also dispatched. They tossed on the sea for nearly two hours before returning to the port in disappointment.

All four Chinese submarines have surfaced, and the distance from Tarapeg Port is about 6 nautical miles. The four submarines are lined up in a single column, about 2 chains apart, and are heading eastward at a low speed of 5 knots.

Sa Shijun stood on the bridge of No. 1048. On the front and rear decks of the submarine, two 12-barrel 240mm rocket launchers were installed, and the gunners were adjusting the direction and height of the muzzle according to the orders of the gun captain.

"The orientation is 97, the distance is 10,600, all the guns are ready!" The gunman's voice came from the boat. He is now using his periscope to measure the target distance.

"The No. 1 gun position is ready!"

"The gun position No. 2 is ready!"

"The shooting is ready, sir!"

Sa Shijun glanced at Lin Feng and signaled that he could launch a shelling attack!

"Start!" Lin Feng shouted loudly to the microphone in his hand.

"Start launch!"

A wave of roar suddenly sounded on the sea surface. The explosion sound produced by the rocket launcher when it was launched was much smaller than that of the naval gun, and there was almost no recoil. However, the momentum caused was not small. The tail flame ejected from the behind the gun barrel immediately illuminated the entire sea surface. Rockets, with long tail flames, the engine roared and cut through the sky, roaring towards the distant night sky.

In just 2 minutes, 24 rockets were launched, and the flames illuminated half of the night sky.

Looking through the telescope, there were clusters of fires rising from the Tarapege Port, and several places even ignited fires. At this time, about 23 Japanese cargo ships were parked in Tarapege Port, six of which were oil tankers coming from the South Ocean. Due to the lack of a special artillery control system and the large area of ​​the rocket itself, about one-third of the shells fell on land. Even so, the four submarines fired nearly 100 shells in this round of volleys. Even if the blind cat hit a dead mouse, there were always several Japanese ships who were hit by the bad luck.

"Put the launcher away, right rudder 30, and move forward at full speed!" Lin Feng immediately issued a quick retreat order after the launch. At this time, a fire rose into the harbor. It seemed that an oil tanker was hit and an even more violent explosion occurred.

The only thing that Sa Shijun regrets is that these rocket launchers cannot automatically load the projectiles. Each rocket launcher takes 15 minutes to complete the reloading, and the submarine must always float on the sea. Otherwise, he may order several more rounds of artillery fire.

The Japanese shore defense artillery finally opened fire aimlessly, and the shells landed several kilometers behind the submarine hole. At this time, Lin Feng had ordered the abandonment of attacking again. The Fifth Squadron was preparing to follow the Mariana route to go outside Tokyo Bay to try their luck. (To be continued...)
