Love in the Courtyard: Starting with Engineers

Just then, the purchasing department director stumbled into the workshop, clutching a telegram in his hand, his voice trembling:

"Chief Engineer, bad news! Several Western countries have jointly issued a 'military supplies embargo,' intercepting all our orders for tungsten-chromium alloy and precision pressure sensors. Even our previously signed long-term supply contracts have been unilaterally terminated!"

"What?" Old Wang exclaimed in surprise.

"Without tungsten-chromium alloy, the gun barrel's strength simply won't meet the requirements. Even if the machining precision is up to standard, it will deform after ten minutes of continuous firing. Without precision sensors, the anti-aircraft gun's fire control system becomes blind; how can it lock onto high-speed targets?"

Upon receiving the telegram, Li Yu formally established the "Technology Blockade Alliance," which prohibited the export of any special materials, precision components, and technical equipment related to military industry to my country.

At the same time, a maritime blockade was initiated to intercept all military supply transport ships passing through international waterways.

This means that Longxing Shipyard's plan to mass-produce shipborne anti-aircraft guns has suddenly fallen into a desperate situation of "having no rice to cook".

"Factory manager, an urgent telegram from the military." The communications officer rushed over and handed over an encrypted telegram.

Li Yu opened the package and his pupils contracted sharply. "An island reef in the South my country Sea has been blockaded by an enemy naval formation, and its supply route has been cut off. The Weihai destroyer needs to rush to its aid with its shipborne anti-aircraft guns."

"Longxing Factory is required to deliver 10 qualified anti-aircraft guns within 10 days, and must solve the problem of electronic interference resistance to ensure that they can effectively intercept enemy missiles and carrier-based aircraft in actual combat."

Ten days, ten qualified anti-aircraft guns, and they also had to break through electronic jamming barriers.

Li Yu gripped the telegram tightly, his knuckles turning white. The existing stockpile of tungsten-chromium alloy was only enough to produce three cannons, and even those three were susceptible to accuracy issues due to interference.

The development of anti-electronic interference systems, although there are blueprints, has not made any substantial progress so far because of a lack of leading personnel.

"Factory manager, I have an idea."

A gentle voice rang out, and Zhao Wenshan, with his parted hair and gold-rimmed glasses, walked over.

He was a technical expert who had just returned from overseas two weeks ago. With his solid theoretical foundation and work experience in overseas military enterprises, he was quickly appointed as the deputy technical leader of the anti-aircraft gun upgrade project.

Zhao Wenshan adjusted his glasses and said in a calm tone, "Regarding anti-electronic interference, I have been exposed to related technologies abroad, and I can lead a team to tackle this problem."

Li Yu's heart stirred; this person seemed to have decent technical skills. "Good, you will lead the formation of a special task force to prioritize solving the anti-interference problem."

A barely perceptible glint flashed in Zhao Wenshan's eyes as he nodded and replied, "Please rest assured, Factory Director, I will do my utmost."

However, Li Yu did not notice that when Zhao Wenshan turned to leave, he secretly put a piece of paper labeled "Core Parameters of Anti-aircraft Artillery Fire Control System" into his pocket.

That afternoon, Longxing Factory held an emergency meeting.

Li Yu stood in the center of the conference room, his gaze sweeping over the technical experts present. His voice was firm: "Whether it's blockade or interference, the task of delivering 10 qualified anti-aircraft guns within 10 days must be completed!"

"If we don't have tungsten-chromium alloys, we'll develop alternative materials ourselves. If we don't have imported sensors, we'll make them ourselves. Electronic interference won't stop us; on the contrary, it will make us grow faster!"

After speaking, Li Yu took out a stack of brand-new blueprints from the drawer, placed them on the conference table, and then passed them to everyone present.

The adaptive frequency hopping radar system on the drawings had a clear structure and detailed parameters, far exceeding the understanding of everyone present.

"This is the optimal solution. It can capture enemy jamming frequencies in real time, automatically switch between 128 operating frequency bands, and while the jamming is rendered ineffective, the radar detection range can also be increased by 50%," Li Yu said.

The room was completely silent. Looking at the groundbreaking design on the blueprints, I was filled with awe.

Old Wang, trembling, stroked the blueprints: "Chief Engineer, this...this technology is at least twenty years ahead of the West! How did you manage to do it?"

Li Yu did not explain, but simply said, "Produce according to the blueprints, and process the core components using a five-axis machine tool."

Just then, the air raid siren suddenly blared in the factory area!

The communications officer rushed in, his face ashen. "Report to the chief engineer! Radar has detected three unidentified reconnaissance aircraft that have entered our airspace from the southeast and are rapidly approaching the Longxing Factory."

"The air force interception force is still on its way and is expected to arrive in 15 minutes!"

Li Huaide, who was standing to the side, suddenly stood up. Li Yu patted him on the shoulder and said, "Don't panic."

A hint of smugness flashed in Zhao Wenshan's eyes, but he feigned anxiety and said, "Fifteen minutes is enough for them to complete their reconnaissance! Our anti-aircraft guns haven't been deployed yet, what are we going to do?"

Li Yu's lips curled into a cold smile: "Don't worry, they can't fly over the factory area."

He picked up the internal phone and dialed directly to Company Commander Zhang's office: "All individual air defense units, take your positions. Target: Unidentified reconnaissance aircraft that has intruded into our airspace. Kill without mercy."

"Roger! Individual air defense unit has locked onto the target!"

No more than 30 seconds after the phone call ended, three muffled explosions were heard outside the conference room, each no more than 10 seconds apart.

Everyone ran to the window and looked out. In the distance, three reconnaissance planes were seen emitting thick black smoke as they fell like kites with broken strings, their wreckage crashing into the woods outside the city.

"This...this is how it was taken down?" Old Zhang was dumbfounded.

"It's a man-portable air defense missile!" Old Wang explained excitedly.

"I heard the factory manager say before that this weapon has a range of 8 kilometers, a speed of Mach 3, and can lock onto any low-altitude or high-altitude target with a 100% hit rate. I didn't expect to see it again so soon!"

Li Yu calmly withdrew his gaze: "From today onwards, any reconnaissance aircraft that intrudes into our airspace without permission will have only one fate: to be shot down!"

With the threat of the reconnaissance aircraft eliminated, the electronic interference in the workshop vanished instantly, and the accuracy data of the five-axis machine tool immediately returned to normal.

Having dealt with the issues of anti-jamming and reconnaissance aircraft, Li Yu turned his attention to the problem of the supply disruption of special metals.

"Now, I'm giving you three days to produce a qualified rare earth tungsten alloy."

"The anti-interference system must be debugged within 48 hours."

"The production team is working at full capacity, using new alloys and new radars, to complete the production and assembly of 10 anti-aircraft guns within 10 days."

"The West wants to strangle us? They're wrong. We can not only build it ourselves, but we can build it better and stronger!"

"We guarantee to complete the mission!" everyone shouted in unison, their eyes blazing with fighting spirit.

After get off work, Zhao Wenshan hid in a secluded corner and secretly sent an encrypted telegram overseas: "Target has mastered advanced anti-jamming technology and air defense weapons. The plan has failed. Requesting further instructions."
