Azur Lane: Silent Service
Chapter 34 - Siren Confusion

My submarine's radar and ESM detected a foreign subject approaching the Azur Lane military base. Based on the wavelengths detected by the surface radar, it was Siren's submarine line preparing to launch a surprise attack on the second wave.

The exit of Azur Lane military base is heavily guarded by the Military Police due to the incident of the destruction of a ship belonging to the Royal Navy.

If they get out of this place for no apparent reason, they will attack my submarine without notice.

“Ugh.. It will be very troublesome,” my little grumble to break the silence.

Sofia and Jimmy Carter prepare a siren submarine intercept line on the Tactical Map Operation screen. The depth of the sea and the temperature of the sea water greatly affect the battle of the submarine. There are two rules that must be considered for submarine combat, namely attack strategy and defense mechanisms from attack. Detecting enemy submarines and avoiding detection of enemy submarines is a common battle for submarines.

The result of the battle lay in the information of the sea that became the battleground. Diving mistakes and minor carelessness would be fatal attacks. Unlike surface ships, submarines are not shaken to receive fatal damage at the submarine's vital point. The small damage will widen rapidly due to the pressure of the sea water changing the submarine's skeletal structure.

So, I plan to avoid detection of siren submarines and sink them before they realize the whereabouts of my submarine.

*beep..

*Tiiit..

My submarine's radar and ESM became silent. The small dots observed in the radar range have disappeared completely.

“They have got enough data for the surprise attack and are back diving,” Jimmy Carter said by marking the last position of a foreign subject detected in the surface radar range on the Tactical Map Operation screen.

I felt a bad feeling about the strange siren movement. The movement of those who launched submarine units before the attack was a rare anomaly in previous siren invasions. The power of the siren lies in the technology and the number of mass sirens that support the attack. Techniques such as collecting data and sending submarine units to perform spy stunts are new to sirens.

Except.. If it was related to the death of the Temperance Arbiter who had become the USS Jimmy Carter or something that changed their actions.

“Maybe.. This has something to do with you, Jimmy Carter?” my many.

“Unng?” reply Jimmy Carter with a confused expression.

I stared at the face of Jimmy Carter who was flowing in thin sweat and removed some of the interception path choices that had been made.

“Their movements look very strange, don't they?” I looked at Jimmy Carter.

“Our attack strategy will change from the previous tactic, this one siren has developed from before,” continued.

“I can't deny it. The siren movement this time moved with great caution. Most likely, they assumed that the USS Enterprise that had defeated me was at the main base of Azur Lane,” Jimmy Carter replied.

“Or.. Something had happened and made the siren party feel confused about the situation that had happened. A few hours ago, Azur Lane's emergency radio frequency received an emergency signal from the USS Enterprise,” Sofia explained her discovery by playing the sound recorded by my submarine.

The voice recording played by Sofia came from the Eagle Union Fleet with the USS Enterprise Flagship. On their way home after a routine patrol 200 nautical miles from the exclusive Azur Lane zone, they discovered a strange siren activity. A number of mass-produced sirens moved in groups and formed a formation like to attack something. The USS Enterprise takes special measures to follow them and realizes the siren's distance to the main base of Azur Lane.

The battle between the Eagle Union Fleet led by the USS Enterprise and the siren convoy was inevitable. The final report of the USS Enterprise radio transmission explains the purpose of the siren attack due to the failure of one of the Elite Sirens to search for an object stored by one of Admiral Azur Lane.

After listening to the radio transmission of the USS Enterprise which ended in an explosion sound, an emergency signal was sent by the USS Enterprise. Azur Lane's side, which had problems in the previous incident, formed a special Fleet to conduct rescue operations. It was a big gap for me to get out of this place and hunt down the siren submarine that had been detected.

“Good work, Sofia!” I praised Sofia and stroked her hair.

Sofia received the caress of my hand with a wide smile and glare of eyes that seemed to mock Jimmy Carter.

Small flames and bursts of electricity occurred between them..

However, this room was hot with a silence that looked at each other.

“Umm.. M-masters.. I found a small clue as to the attack that the siren submarine is about to make. If they were to use the old tactic of being updated all of a sudden, there was a possibility that the Siren Elite was giving out offensive instructions behind the scenes. Siren submarines will attack in groups according to Siren Elite directives through digital transmission. We need to capture the digital transmissions used by siren submarines to get their point of location,” the explanation Jimmy Carter uttered sounds reasonable.

Submarines are not a type of loner unit in carrying out attacks involving large targets. In the history of attack submarines that penetrate enemy defenses with sudden attacks, their movement involves a group of submarines to attack at one time. A clear example of the attack was applied by submarines belonging to Nazi Germany, they developed submarine units that move in the formation of “Wolfpack”.

However, for submarines in the modern era. Using the Wolfpack formation is a fatal mistake due to the noise level and is vulnerable to being detected if moving in groups. The development of submarines that relied on silent functions and underwater detection gave birth to an underwater killing machine that was very effective for disrupting surface ship convoys. However, it does not make the submarine a loner unit because of certain limitations experienced by the submarine.

Jimmy Carter showed me a small gap in the movement of the siren submarine, the Tactical Map Operation screen and my surface radar showed red dots in the shallow depths of the sea.

Looking at the data that Jimmy Carter was showing, I understood the small gap that he was looking at.

“So so, I get it now. They can't dive more than a hundred meters?” my many.

“It's true, Master. Siren technology for mass-produced submarines is only capable of diving to depths of 50 meters. However, for Siren Elite which has siren submarine system. Ughhhh.. I don't want to meet them especially with circumstances like this.”

“Eh? What is it about Siren Elite that uses a submarine system?” ask Sofia.

“They are very troublesome. The ability to dive and move below sea level is very different from that of mass-produced siren submarines. We need a lot of underwater explosives to lure him out of the sea surface,” replied Jimmy Carter.

“...”

“...”

Sofia and I were stunned after hearing that explanation.

Slowly.. We chuckled and looked at Jimmy Carter with a faint smile.

“Eh?” look at us who are laughing. The expression on Jimmy Carter's face was filled with curiosity and small questions that he wanted to ask.

“Jimmy Carter.. Take a good look.. Our submarines have almost the same technology as the Siren Elite. The USS Seawolf is designed to move quickly to attack targets, has an unlimited range of range, is capable of diving below sea level without surfacing for months, and the only one who restricted this submarine was.” I stopped my words by sighing deeply.

“Food availability..” further my word.

After I said those words, a loud stomach voice rang out from Jimmy Carter's stomach.

“And the first rule after becoming a ship girl is a stomach need that must be considered especially as a girl who is soft and innocent,”.

Hearing my words, Jimmy Carter's face bowed lethargic after his stomach rang out loud. The adaptability of Jimmy Carter is fairly fast but has a limit on the general instinct of humans. Trivial things like eating, sleeping, and cleaning up are foreign to Jimmy Carter.

That's why.. Sofia and I taught her so she could mingle with other girls.

Well, my work keeps growing and my need to take care of them keeps increasing.

Especially with the shape of Jimmy Carter's body, I'm very worried if there are wild predators eyeing his body.

Well.. Do I need to teach him how to remove traces of human corpses?

I can only hope that such an event will not happen.
