At the time of World War II, there were generally two types of German submarines and their performance.

One is a 500-ton submarine with a cruising range of 11,000 nautical miles, and the other is a 700-ton submarine with a cruising range of 15,000 nautical miles.

But now almost all of these types of U-shaped submarines have been eliminated by Chen Yanlong, and all of them have been replaced with long-range aircraft carriers of the Yi 400 series.

While the new commander John Tovey and his admiralty were discussing the battle plan, the British convoy codenamed 'OB-300' had been targeted by the long-range submarines of the I-400 series that were gradually converging.

"Captain Galeen! We have already come to the aid of 10 I-400 series ocean-going submarines in our vicinity, should we carry out a torpedo attack right now? ”

Adjutant Lepurn reported to Captain Garen.

"It's not time yet, we still need to wait for the Führer and Marshal Dönitz to send over other U-boats, and the I-400 series ocean-going submarines, there are probably more than 30 or so! Because this British transport fleet has an escort fleet, if we don't attack them with superior forces, I am afraid that they will escape or capsize in the gutter! ”

"When they arrive, we will be able to carry out a surprise attack immediately, using wolf pack tactics to wipe out these British escorts and transport fleets in one fell swoop!"

Captain Galeen thought cautiously as he looked at the telegram in his hand.

"But our submarines who come to our aid may have to avoid the challenges of hundreds of destroyers, frigates and anti-submarine trawlers of the British and American forces, radar detection and interception, and pursuit!"

Adjutant Leppon worried.

"Perhaps! However, the submarines we are now distributed here are all in groups of three or four, or even two or three in groups. ”

"It's not easy for the British and the arrogant Yankees who are not familiar with the waters in this area to find our exact location!"

After hearing this, Captain Galeen was not the slightest worried.

"Hmmm! I see, then everything is up to you, Captain! ”

Adjutant Leppon nodded in agreement.

"By the way, our cow large oil submarines, how much is coming, our U-boat submarines don't have as much fuel as those I-400 series ocean-going submarines! If we add to it, I'm afraid that we will run out of fuel for a day and night at most! ”

Seeing this, the Garaine suddenly remembered.

"There are three of them, but they're refueling the newly charged submarines on a nearby route!"

Adjutant Lepuen thought for a moment and replied.

"Hmmm! Charge? In other words, is the battery of our submarine still sufficient? Do I need to recharge? ”

Hearing this, Captain Galeen also paid attention to the power problem of the submarine he was on, and hurriedly asked.

"Not yet, we still have plenty of electricity!"

Adjutant Lepuen shook his head and vetoed.

And just as the two of them were asking and answering, in another Yi 400 series submarine, Captain Townes couldn't wait to give orders to all the members of his submarine in a combat state:

"Torpedo launchers ready to fire!"

A few minutes later, when all the torpedo launchers were ready, Captain Townes waited anxiously for his submarine to quietly approach the British convoy he was attacking.

1200 meters, 900 meters, 700 meters......

The I-400 series submarine has reached its imminent sight, and all the torpedoes have been aimed at the bottom of the target, ready to reap the lives of all the crew members on board.

"Torpedo launcher, put!"

After making sure that he had successfully approached and locked onto the target, Captain Townes decisively gave the order for a torpedo attack.

"Whoosh! Sou! Whoosh......"

As soon as his order was given, several deep-water torpedoes whizzed away from the torpedo tubes at the fastest speed and frantically pounced on its target.
