"I need to speak with the old man about something."

The vice principal looked at the approval slip in Yuan Yi's hand and shook his head speechlessly.

"I knew you weren't holding back any good news!"

Let's go.

Naval academies not only teach but also shoulder the important responsibility of research on submarines, warships, and other related fields.

"Old Huang is 99 years old this year and basically has no intention of getting involved in things anymore."

After hearing the vice principal's words, Yuan Yi understood what he meant.

Older people tend to have more energy.

Huang Lao is known as the father of nuclear submarines.

That requires discussing creating something from nothing.

At that time, neither the Chinese military nor the researchers had ever participated in the imitation of conventional submarines from Russia. As for what nuclear submarines looked like, no one had ever seen them.

Without processing equipment for 90-centimeter-thick steel, the development of special steel plates for submarines had not yet begun. It was only after the successful explosion of China's first atomic bomb that the nuclear power problem was solved, and "Project 09" made progress.

Huang led the designers to create a teardrop-shaped submarine with lower underwater resistance than conventional streamlined submarines, while also solving the maneuverability problem of nuclear submarines.

Foreign technological blockades have increased the difficulty of research and development. To enhance the stability of its submarine during missile launches, one country specifically designed a compartment to house a 65-ton gyroscope, making underwater space extremely precious and occupying the submarine's most valuable space.

After repeated calculations, analysis, and research, Huang's team solved the problem of the 65-ton gyroscope by adjusting the layout of equipment inside the nuclear submarine, saving space for the submarine, and making the roll angle, pitch angle, yaw angle, and heave angle close to zero.

From 1970 to 1981, China successively launched its first nuclear submarine, delivered its first nuclear-powered submarine to the navy, and successfully launched its first nuclear-powered missile submarine, becoming the fifth country in the world to possess nuclear submarines after the other four permanent members of the UN Security Council.

In early 1988, the nuclear submarine conducted a deep-sea diving test in the South China Sea according to its design limits.

Mr. Huang personally dived to a depth of 300 meters. At a depth of 300 meters, the hull of the nuclear submarine had to withstand a pressure of 30 kilograms per square centimeter. Mr. Huang directed the test personnel to record various relevant data and succeeded, becoming the first person in the world whose chief nuclear submarine designer personally went underwater to conduct a deep-sea diving test.

In other words, without Huang Lao, our mother wouldn't have had nuclear submarines.

The two arrived at the family quarters within the academy.

A detached villa.

"That's where Elder Huang lived here."

"Of course, Mr. Huang doesn't spend much time here each year."

The vice principal then went up and knocked on the door.

A medical worker opened the door.

Is Elder Huang here?

The medical staff also knew the vice principal and nodded: "In the living room."

The medical staff then made way for them.

The vice principal led Yuan Yi in directly.

"Teacher, I've come to see you."

Yuan Yi looked surprised when he heard the vice principal's words.

He never expected that the old vice principal was actually Huang Lao's disciple.

A robust elderly man was sitting on the sofa in the living room.

He looked up after hearing what was said at the door.

"Little Zhou."

Why did you come here?

As he spoke, his gaze fell upon Yuan Yi, who was standing next to Vice Principal Zhou.

"This is a staff officer sent by JW. He has something to discuss with you."

Yuan Yi saluted Elder Huang directly.

"Mr. Huang, there is something I really need your help with this time."

"This is a very important matter, and only your intervention can help us."

A glint flashed in Old Huang's eyes, completely unlike the eyes of a 99-year-old man.

"oh?"

The old man looked puzzled.

"Come with me to the study!"

He stood up shakily and walked alone toward the study.

Yuan Yi followed directly behind, while Vice Principal Zhou, who was standing to the side, stopped and did not follow.

Neither Yuan Yi nor Old Zhou told him to follow along, which means that it is not appropriate for him to know this news at the moment.

Yuan Yi closed the study door and then looked at Old Huang sitting at the desk.

"Kid, just say what you want to say!"

Yuan Yi didn't hesitate and immediately took out the computer and placed it in front of Old Huang.

"We need a deep-sea submarine that can carry hundreds of people."

"Submarines need to be equipped with a variety of weapons and equipment."

"In addition to the internal torpedo tubes and vertical launch tubes, we also need to install some external firepower."

After listening to Yuan Yi's words, Old Huang pondered for a moment.

"Deep-sea submersible?"

"What? You want to explore the deep sea?"

Yuan Yi did not hide anything from this medal recipient, the father of submarines.

They immediately opened the video and played it for Old Huang.

As Mr. Huang watched the video, his expression shifted from calm at the beginning to excitement at the end.

After the video finished playing, Old Huang looked at Yuan Yi excitedly.

Yuan Yi nodded: "It's true, I explored it myself."

Mr. Huang had seen Yuan Yi in the video before.

"So, the higher-ups are planning to develop that unknown world?"

Yuan Yi nodded: "Preparations are currently underway."

"I am the leader of the exploration team."

"We don't know the situation in that world right now, based on the information we have."

"In the past, there was only the sea, so we needed a submarine that could accommodate about 500 people."

"Furthermore, the submarine needs to have enough space to carry 500 people and provide them with supplies for half a year."

"We also need to bring various equipment!"

After hearing Yuan Yi's words, Old Huang looked at him.
