Azur Lane: Silent Service
Chapter 11 - Siren Weather Device
The cold ocean looks calmer than the storm that hit the ocean. Under the silence of the cold water, I followed the movement of the siren submarine approaching the small island. Passive sonar contact reports showed Siera's activity scattered around the island.
“Oh... My... Isn't this a big catch?” ask Sofia.
“Yeah, according to my prediction” reply.
“Master, it looks like a Royal Navy convoy has joined the battle.”
My main system is now switching to passive sonar reflections that detect the impact of hard objects that touch the surface of the water. The condition of my submarine is entering silent running mode. So, I used a headset to hear things around my submarine.
*Splaaaash...
*Duuug...
*Bllluuurr...
“Not wrong, it was a large-caliber bullet fired from Battleship” I said as I glanced at my sonar system that captured the Royal Navy's movements.
“Master, no new Siera contacts. Different from Siera's contacts who emit sound noise. This one contact does not move but emits a siren communication wave that is difficult to understand. The submarine database was unable to break the communication wave code.”
“Bearing?”
“Bearing 340!”
In response to Sofia's report detecting strange irregularities in passive sonar, I immediately checked the report with Tactical Map Operation data. The distance between the island and the target of Siera looks very far. Looking at the awkward conditions, I checked the movements of the Royal Navy who kept a distance from the island. My passive sonar receives a signal identifying the mysterious waves emitted by Siera.
“Sofia, what is the thickness of the ice sheet above us?”
“More or less, it is around 20cm to 30cm! The echoing reflection of sonar makes it difficult for us to get a definite answer” Sofia replied.
“Ah! If we move near the island. We'll pass through a thick layer of ice” Sofia continued.
“Through the ice sheet, huh? Well... Our condition is very bad. The only weapon that can be used is an underwater torpedo because the surface of the sea is covered with ice. What about the new Siera contacts? Is there a change of location and passive sonar?” my many.
“Nothing, Master. He remained at the previous point.”
“Uhm... Is there a thick ice sheet around it?”
“Based on the reflection of passive sonar, Siera targets are outside the ice sheet zone.”
“Good! Sophia! Adjust the direction of the submarine towards the target at level 3 speed. After passing through the ice sheet, raise the submarine to the periscope depth and prepare the Hunter Killer Drone in the torpedo launcher tube!” my orders.
“Ready, Master!”
I don't know why, I can feel a good feeling about this. A target that is not moving but emits a siren communication wave that is difficult to understand? There's only one answer about that.
Siren Weather Device!
I'm so sure about that!
I found you, Siren Weather Device!
Destroying you would be the turning point that helped the Royal Navy convoy attack. The severe weather disturbance that disrupted their ship's radar was soon over.
Well, this is my chance to destroy it and show the power of the Seawolf-class before Royal Nayy.
My submarine body is moving through a thick layer of ice. Under the ice sheet, the ocean felt extremely silent. The reflection of the sound waves was too echoing and made my sonar sensor confused to determine the direction. The Tactical Map Operation that appeared on the main system of my submarine had a glitch. The disturbance was too troublesome, especially with the direction of my submarine's destination shifting two degrees from the destination.
“Sofia, customize sonar sensor with gyroscope sensor. If both sensors display different numbers. Quickly adjust with gyroscope sensor!”
“Un! Understood! Calibration of sonar sensors with gyroscope sensors!
My submarine journey has had difficulties due to Siren Weather Device interference. My submarine propeller worked hard to be in silent mode while cruising down the thick undercarriage of the ice. Deep-sea contact was not detected, passive sonar sweeps did not gain any new contact, and Tactical Map Operation monitored the movement of busy Royal Navy convoys around the island.
All of a sudden, I got a communication wave jamming through my submarine network.
*Bzzz... *Bzzz...
*Www.zzz.tt...
“Urm, Sofia..”.
“I know, Master! Communication system trying to catch siren communication wave and trace back its position.”
*Buuuuzzz...
*bwcztt...
“Master, our database has no information regarding this communication wave. But, we managed to trace back the direction of the siren communication wave. The communication wave that came from the island to the target Siera that we are pursuing” Sofia's speech made me speechless.
“Sofia, send the siren communication data that has been obtained to my main system!”
“I-This, Master!”
My main system now contains random data that has been obtained. That data is just one and zero number codes, in other words it is siren digital data that uses binary code. The communication signal used by the Azur Lane ship is an analog channel that anyone can hear. For digital signals, there is only one answer to this: sirens.
“Sofia, take the submarine to periscope depth and raise all our radars! Lower the speed to 0. We will attack two targets at once! Prepare launch tubes one and two with Hunter Killer Drone, triple launch tubes with UGM-84 Harpoon, and Tomahawk Anti-Ship Missile on fourth tube!”
“Government accepted! Setting up Solution on specified tube!”
My submarine's main system worked hard deciphering the binary code until the siren program's command line filled my main screen, the digital signal Sofia captured was from The Empress III. He sent a command signal to the Siren Weather Device to change the weather of the storm-filled battle. The communication used by sirens is quite advanced, they have used digital channels for communication.
Very clever!
However, it would be useless if I understood the line of commandments!
For now, I will hold those codes and study them. If I could create one special exploit that uses siren communication network. Fufufu... It will benefit my condition against the siren.
“Master, Solution 1 and Solution 2 are ready!” report Sofia.
“Prepared Solution 3 and Solution 4!” continue commandment.
“Understanding! Solution 3 and Solution 4! ETA 15 seconds!” sahut Sofia is full of passion.
I glanced at the remaining ammunition stockpile on my submarine.
\=-\=-\=-\=-\=-\=-\=-\=-\=-\=-
The Mark-48 Torpedo x41.
The Mobile Submarine Simulator x30.
UGM - 84 Harpoon x3.
Tomahawk Anti - Ship Missile x18.
Tomahawk Anti - Land Missile x20.
The Semiramis Underwater Jammer x100.
Hunter Killer Drone x11.
\=-\=-\=-\=-\=-\=-\=-\=-\=-\=-
Uh! my ammo supply is running low! If only I hadn't gone overboard in the previous attack. A shortage of ammunition like this will not happen.
But if I don't do the test. I will not know the impact of the damage from UGM-84 Harpoon on siren defense.
The price paid for the information is already commensurate with the result!
No regrets about this.
Yep! Consider it part of the experience and curiosity that is answered.
“Master, Solution 3 and Solution 4 are ready!” report Sofia.
I re-entered my serious mode, not the time to cry over reduced ammo. This is war! A war without a shortage of ammunition is not a war!
“Set Solution 1 to Siera target! Convert Hunter Killer Drone data transmission into live broadcast using Alpha channel security protocol!”
“Set Solution 2 to Royal Navy convoy! Convert Hunter Killer Drone data transmission into live broadcast using Hotel channel security protocol!”
Following the command I gave, Sofia immediately launched the Hunter Killer Drone and turned the Tactical Map Operation screen into a live broadcast with the Hunter Killer Drone point of view.
I observed the live broadcast of the Hunter Killer Drone heading towards the target Siera and a wide smile graced my face.
“Bingo!” my spoken.
Right in front of me, a tower with a red core was clearly visible. The building was black with six pillars embedded in the ocean. At the top of the building it consists of a red crystal core and a purple laser beam that is flanked with two large antennas.
“Fufu... Hahaha!!” I laughed after finding the Siren Weather Device.
“Sofia, create a communication channel with King George V! I need to talk to him.”
“Urm, Master... That will tell us our position” Sofia replied.
“Ah! Also true. In that case, use the light signal on the Hunter Killer Drone that airs around King George V.”
“What message would you like to submit, Master?”
“Ladies, winter is over! Send that message!”
“Understanding! Urm... Master...”
“What's up, Sofia?”
“It's just my feeling or the Master is teasing them?”
“It's not like that, Sofia. This is just communication between Flagships!” my firmness.
For some obscure reason, Sofia doubted my words.
