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

The early winter night came early, and it wasn't long before the sea was completely dark, and by the time submarine No. 1048 approached the port of Tara Bag, it was already past nine o'clock in the evening.

The lights in the harbor of Tara Peg are brightly lit, and the tall lighthouse standing at the entrance to the Cape Canavera channel is even more visible from more than a dozen nautical miles.

The Japanese did not have advanced radio technology, and at this time, most of the warships were not equipped with sonar detection systems, and Chinese submarines were able to boldly carry out close reconnaissance. At this time, through the gap in the atoll, it can be clearly seen that there are about 30 cargo ships moored in the harbor. The Japanese troops stationed on Saipan had about a wing, and the navy was not very strong, with only two destroyers and a few patrol gunboats.

Ten minutes later, Sa Shijun, who was sitting in front of the periscope, and Lin Feng, the captain of the ship, noticed that a freighter had sailed out of the channel almost at the same moment.

"A bulk carrier with a displacement of about 2500 to 3000 tons!" Sa Shijun also had nearly thirty years of experience in the navy, but he could not quickly discern the tonnage of a ship in a periscope like a submarine commander.

"Shall we attack it?" Sa Shijun asked.

"It's just an appetizer, let the other submarines deal with it, and we'll see if we can find a chance to sneak into the harbor." Lin Feng said confidently that the Japanese were very lax in guarding the port of Tara Peg, and it was obvious that there were no mines along the channel, but anti-submarine nets would definitely be arranged.

"Why not use rocket artillery? Now the steamers in the harbor are lit up, the targets are obvious, and they are all gathered near the pier. We only need to carry out a covering artillery bombardment on that area to be able to inflict enough damage on the enemy. Sa Shijun said, "When you sneak into the harbor and then want to quit. There is a great danger. ”

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

"How can you know if you don't try? This may be able to invent a new submarine tactic. Sa Shijun encouraged that he also wanted to see how powerful these rocket launchers were. I've heard that in the Army, this thing works well when suppressing artillery fire. But how effective it can be at sea has not been specifically verified.

"Half the speed, turn to 90!" Lin Feng gave the order to retreat, and now that the submarine was less than 5,000 meters away from the port, he needed to retreat to a slightly safer distance.

After about 20 minutes, a loud bang was heard from the water in the distance, and it was clear that the unsuspecting Japanese freighter had been torpedoed by a Chinese submarine waiting outside not long after leaving port. In the distance, about six nautical miles away, a blaze burned on the pitch-black sea, like a matchstick drawn in the periscope. Approximately 7 minutes later, sonar corps reported capturing the sound of three high-speed propellers. He is rushing to the accident site at full speed.

It seems that the Japanese reacted quite quickly.

"Sir, I think it's good at around 9,000 meters, so that the accuracy of hitting will be higher." Lin Feng no longer cared about the situation of those Japanese patrol boats, and began to study the artillery tactics on the charts. It was originally the territory of the Germans, so the Chinese navy had detailed charts in its possession.

"Well, I think we should test the current new tactics at around 13,000 meters, how far can the periscope see after the submarine surfaces?" Sa Shijun said. "If this tactic is successful, our submarines will be able to get close to the coast of Japan. Go and attack their coastal cities and industrial facilities. ”

"The altitude of the submarine is not enough, it can only observe 16 nautical miles during the day and only about 8 kilometers at night, and the radar on the submarine can detect the target, but it cannot provide fire control numbers. But now that there are lights in the port, 13 kilometers should be no problem. Lin Feng said.

"In the caliber of our artillery. It is possible that the Japanese thought that they had been attacked by a fleet of heavy cruisers, and it is conceivable that tomorrow all the transports on this route would take refuge in the harbor, and their sea transport would be temporarily interrupted. And they will send a large number of aircraft and warships in the area to find the 'attack fleet' that does not exist. Sa Shijun said, "What a new tactic." It is the one that can exert its maximum power at the beginning, and over time, the enemy will naturally find new ways to deal with it. ”

The Japanese continued to search the site of the cargo ship's accident, and the attacking Chinese submarine had already withdrawn, and after a while, the two destroyers stationed in the harbor also dispatched and tossed around the sea for nearly two hours before returning to the harbor.

All four Chinese submarines surfaced and are now about 6 nautical miles away from the port of Tara Peg, and the four submarines are lined up in a single column, about 2 chains apart, and are heading east at a low speed of 5 knots.

Sa Shijun stood on the bridge of No. 1048, and on the front and rear decks of the submarine, two 12-barreled 240mm rocket launchers had been propped up, and the gunners were adjusting the direction and height of the muzzles according to the orders of the gunner.

"Azimuth 97, distance 10600, all guns ready!" The voice of the gunner, who was now using the periscope to distance the target, came from inside the boat.

"Gun Position 1 is ready!"

"Gun Position 2 is ready!"

"Ready to shoot, sir!"

Sa Shijun glanced at Lin Feng and signaled that it was time to carry out an artillery bombardment!

"Let's go!" Lin Feng shouted loudly to the microphone in his hand.

"Start firing!"

There was a roar on the surface of the sea, and the explosion sound produced by the rocket artillery when it was launched was much smaller than that of the naval gun, and there was almost no recoil, but the momentum caused was not small, and the tail flame sprayed from behind the barrel suddenly illuminated the entire sea surface. One rocket after another, with a long tail flame, the engine roared through the sky, whistling towards the night sky in the distance.

In just 2 minutes, 24 rockets had been launched, and the flames suddenly lit up half of the night sky.

Looking through the binoculars, the port of Tara Peg was lit up in clusters of fires, and in several places there were fires. At this time, about 23 Japanese freighters were berthed in the port of Tara Peg, six of which were oil tankers coming from the South Seas. Due to the lack of a special artillery control system, and the large dispersion area of the rockets themselves, about one-third of the shells fell on land, even so, the four submarines fired a total of nearly 100 shells in this salvo.

"Put away the launcher, right-hand drive 30, full speed ahead!" Lin Feng immediately gave the order to retreat quickly after the launch, and at this time, a sky-high fire rose inside the harbor, and it seemed that an oil tanker was hit, and an even more violent explosion occurred.

The attack was a great success, and the only regret was that the rocket launchers could not be reloaded on their own, that it would take 15 minutes for each rocket launcher to reload, and that the submarine would have to remain afloat at sea, otherwise he might have ordered several more rounds of shelling.

The Japanese shore defense guns finally opened fire aimlessly, and the shells landed several kilometers behind the submarine hole, at this time Lin Feng had already ordered to abandon another attack, and the fifth squadron was ready to follow the Mariana route and try its luck outside Tokyo Bay.
