200 nautical miles east of Tokyo Bay, it belongs to the deep sea of the Pacific Ocean, with an average water depth of more than 2,000 meters.

Beneath the sparkling sea, it seems that it will always be so dark and dull.

A giant steel monster about 74 meters long, 10 meters wide, and about 6 meters in draft is quietly hiding in the depths of this dark ocean that is difficult to reach.

Darkness and the sea gently wrapped around the beast that exuded an icy steel aura all over its body, and the high-curvature seven-bladed propeller stirred up a series of tumbling wakes in the dark and gloomy water.

"Captain, sonar reports, azimuth 349 has received noise."

Tang Yuanhang, the deputy captain of the navy, who was dressed in dark blue as a training report, walked quickly and silently at his feet, and whispered to Liu Yang, who was contemplating.

Liu Yang's two thick eyebrows were furrowed, leaned over to find the sea area represented by azimuth 349 on the chart, and asked calmly: "Is it a submarine of the Japanese Navy?" ”

"The noise is very low, and it has not yet reached the standard of the voiceprint signature of the XXI submarine sneaking at a speed of more than eight knots, and the sonar is still being further confirmed." Tang Yuanhang shook his head and replied, "It may be a signal, but it may not be it." ”

"Is it ruled out as a deep-sea creature?" Liu Yang asked again.

Azimuth 349 is the edge of the continental shelf 200 kilometers east of Tokyo Bay, and there is a lot of underwater life in this area, which can easily make sonar miscalculation.

"Sea creatures have been ruled out!" Tang Yuanhang replied with great certainty.

Liu Yang pondered for a moment and said slowly: "Let the sonar intelligence officer continue to analyze and check the voiceprint characteristics of the sneaking in the water below the eight knots of the XXI submarine!" I need accurate grading! ”

After finishing speaking, Ji Yang turned around and gave an order to the diving commander: "Notify all units, prepare to dive!" ”

As one of the sharpest steel teeth of the No. 1 Attack Submarine Squadron of the Second Submarine Detachment of the North Pacific Fleet of the Royal Navy, this Kilo-modified conventional-powered diesel-electric submarine SSL-879 "Breaking Wave 489" boat, which was modeled and built on the basis of the Kilo-class submarine, was originally responsible for the regular combat readiness cruise mission of monitoring the US Navy's Pacific Fleet in the eastern Pacific region.

However, after receiving a combat mission to accompany the 3rd Amphibious Assault Squadron to the South China Sea, starting the day before yesterday, the SSL-879 "Breaking Wave 489" and nine other Kilo and six Seawolf-class attack nuclear submarines have all raised their combat readiness cruise to the level of combat readiness strike.

Because, the submarine forces of the Royal Navy of Donghua are likely to have a "chance encounter" with the XXI submarines of the Japanese Navy.

If this is really illuminated by the active sonar of the Japanese Navy's XXI submarine, the face of the submarine force of the Donghua Royal Navy will really be lost.

Moreover, the commander of the fleet, Vice Admiral Wang Jingchun, gave a secret order to every submarine captain after the fleet left the port, if it encountered a provocation from a Japanese submarine under the water, kill it!

Anyway, what happened under the sea is unsubstantiated, and it is completely unacceptable.

It is precisely because of Commander Wang's secret order that the SSL-879 "Breaking Wave 489", which is the anti-submarine escort of the entire fleet, will be extremely cautious. This means that the officers and men of the SSL-879 "Breaking Wave 489" boat, the war belonging to them may have begun.

Even in order to lure the Japanese submarine over, Liu Yang, the captain of the SSL-879 "Breaking Wave 489", had tried to deliberately make noise before.

Judging from the situation in the past 48 hours, the Japanese submarine is obviously not as arrogant and stupid as Liu Yang imagined.

"Retract the periscope and prepare to dive!" Liu Yang continued to give instructions.

"All ready, the first cabin descends 20 degrees, dives 100, and expel the air!" The dive commander in front of the command platform followed with a series of commands: "Depth 200, calibrate the balance, maintain 7 degrees, continue to dive, the whole boat remains silent!" ”

……

At the same time, in the deep sea area on the edge of the continental shelf, 200 kilometers from the coastline of Tokyo Bay, a Japanese Navy's XXI submarine I-78 is also sneaking alone in the dark ocean.

Half an hour earlier, the I-78 had received an order from its flagship, which forced its commander, Kanji Matsumura, to order him to slow down and remain silent in these waters at a speed of five knots.

"Weak signal target spotted!" Sonar officer Koji Kitajima took off his headset and reported to Captain Matsumura Kanji who was standing in front of the console: "Azimuth 237, the signal is not recognized for the time being. ”

"Turn to Bearing 237 and go full speed!" After a short groan, Matsumura gave the order.

With the experience accumulated over a decade-long career as a submarine commander, his intuition told Matsumura that the signal just now must have been a submarine of the Royal Navy.

Although Fleet Commander Koga Mineichi had already issued an order not to provoke the Donghua Royal Navy submarines, Matsumura felt that there was an excellent opportunity to engage with the Donghua Royal Navy submarines, and through the chance encounter with the Donghua Royal Navy submarines, he could gather more information about the noise characteristics of the Donghua Royal Navy's Kilo-class submarines.

Kanji Matsumura, a graduate of the Etajima Naval Academy, was one of the first submarine officers of the Japanese Navy to go with the German Navy's submarine force to the former Tohui Navy to receive the XXI submarine and to train the Tohui Navy's submarine force.

After bringing the coveted XXI submarine back to Japan, Matsumura was very concerned about whether there were more advanced submarines in the Royal Navy of Donghua to enter service.

After the public appearance of the Seventh Fleet of the Royal Navy, Kanji Matsumura could basically judge the Kilo-class submarine of the Royal Navy of the Donghua Navy through the photos taken by the Ministry of Intelligence, and with his professional eye, it was like an enlarged version of the XXI boat. It can also be inferred from this that this Kilo-class is definitely more advanced than the XXI type submarines.

Since the Donghua Empire declared a strong country with the glorious victory of the Donghua War, everyone knows that the Donghua Empire will definitely regard the Pacific Ocean between Paradise Island and the mainland of the Donghua Empire as a big pond in front of its own door.

As an officer of the Imperial Japanese Navy with a sense of honor and responsibility, Matsumura Kanji had already seen the great threat of the submarine force of the Royal Navy of Donghua to the coastline of the Imperial Japan.

The Type XXI submarine can already take out any surface ship of the Imperial Navy's combined fleet without realizing it, the Kilo-class submarines, which are more advanced and powerful than the XXI submarines, and the Seawolf-class, which is even more mysterious than the Kilo-class, in case of a large-scale surprise attack on the Imperial Navy......

Matsumura Kanji really didn't dare to think about it.

And the only way to reduce and weaken this threat is to fully understand the performance of the new submarines of the Royal Navy of Donghua.

It is not only the style of the Japanese Army, but also the Japanese Navy

……

The Royal Donghua Navy Kilo changed the conventional power diesel-electric submarine SSL-879 "Breaking Wave 489" inside.

The pale blue fluorescent screen reflected a suffocating face.

"Maintain the normal one-third frequency and turn to 527 directions!"

Liu Yang stood in front of the display and control system platform and calmly whispered an order.

"Captain, the sonar has come to fruition! The previous signal was the XXI submarine! Now the signal is getting stronger! It's getting faster! Ten knots! Twelve verses! Fifteen knots! It's coming at us at full speed! ”

The good news from the sonar room made everyone in front of the display console, including Liu Yang, breathe a long sigh of relief.

"Confirm the target!" The sonar room again reported it. The XXI submarine, which has a speed of more than eight knots underwater, is a kilowatt searchlight in the dark for the SSL-879 "Breaking Wave 489".

The corner of Liu Yang's mouth kissed a sneer, and he resolutely gave an order: "12 sections of quiet sneaking, direction 426, go around!" Find your chance and kill it! ”
