Courtyard House: I Rely on Time-Space Trade to Build a Nation

[It has been detected that the equipment level of the Republic's Navy is seriously lagging behind historical levels. In order to safeguard national maritime rights and interests, the 1955 New Year's mission is being initiated ahead of schedule. — Marching Towards the Deep Blue]

[Heading Towards the Deep Blue]

[Requirement 1: Transfer Zhu Hui, the female lead of "Reunion After Twenty Years," to be her confidential secretary. Reward: Save 1% of naval equipment exchange points.]

[Requirement 2: Exchange for no less than 10 C28A-type guided-missile frigates (including all design blueprints and materials) in one go, to enhance the Republic's maritime power]

[Requirement 3: Complete the reverse engineering of 20 C28A naval vessels within 10 years, or the right to exchange naval equipment and technology will be permanently revoked]

【兑换代价：2016年共和国外贸型C28A护卫舰单价约21亿系统币（3艘造价9亿美金）】

【折合黄金210公斤/艘。10艘以上兑换产生沃尔玛效应，单艘价格202公斤黄金/艘。诸晖1%价格优惠生效，10艘合计2000公斤黄金。】

"The price is really reasonable, only 2 tons of gold. Zhu Hui? The female recorder who came with us from the Shanghai shipyard?" Zhao Ping'an breathed a sigh of relief after seeing the final price, his mind racing.

But after looking at it more closely, I gasped in shock.

"Ten ships? Twenty ships copied in ten years? These are ships the People's Republic started building in 2012, right? I copied them in 1955?"

Zhao Pingan first opened the parameter page of C28A.

The ship is 120 meters long, 14.4 meters wide, has a displacement of approximately 2800 tons, a maximum speed of 28 knots, and a maximum range of 3500 nautical miles at 16 knots.

The main weapons include 8 C-802 anti-ship missiles,

One H/PJ-26 76mm stealth naval gun (the same type as the main gun on the Type 054A frigate).

1套FM-90N近程防空飞弹系统、2套730式30毫米近防炮及

It has two triple 324mm torpedo tubes and a hangar for carrying Super Lynx helicopters.

Electronic equipment is a hybrid system combining Chinese-developed technologies with Thales' Smart-SMk2 radar and communication system.

The system also thoughtfully pops up a "comparative analysis" window, automatically displaying the data of the C28A frigate and the current mainstream warships in the world side by side.

Firepower Comparison:

C28A：8枚C802反舰飞弹，射程120-180公里，超视距攻击

Red Empire Kotlin-class (commissioned in 1955): 2 twin 130mm guns, with a range of 20 kilometers;

Two quintuple 533mm torpedo launchers, with a range of 8 kilometers.

American Michel-class (design phase):

Three twin 127mm guns, with a range of over 20 kilometers; several torpedoes.

The system also noted: "The anti-ship firepower of one C28A is equivalent to the total firepower of a destroyer squadron in 1955."

Electronic Sensing Comparison:

C28A: SMARTS Mk2 3D multi-beam radar, with a detection range of over 250 kilometers and the ability to track hundreds of targets simultaneously.

Mainstream warships in 1955 had simple air and sea search radars with a detection range of 50-100 kilometers, capable of tracking only a few targets simultaneously.

Commentary: "Electronic systems two generations ahead. Detect and destroy."

Next is a comparison between air defense and anti-submarine warfare:

C28A：FM90N区域防空飞弹（射程15-20公里）+730式7管30毫米近防炮（射速4200发/分）双重拦截，可拦截飞机和反舰飞弹

In 1955, the mainstream warships relied on anti-aircraft guns for defense, offering no protection against missiles.

C28A: Equipped with an anti-submarine helicopter, with an anti-submarine search radius of over 100 kilometers.

1955 warships: depth charges + anti-submarine rockets, range 1-3 kilometers.

Comment: "Air defense capabilities have gone from non-existent to existent, and anti-submarine capabilities have achieved a qualitative leap."

After reading it, Zhao Ping'an remained silent for a few seconds.

He recalled what Commander Xiao had said: "Five years have passed, and our navy still only has those few small boats."

If this thing can actually be made...

Isn't this invincible near the coast?

If we had supply ships, we could easily take a couple of trips around Hawaii and Guam every day!

Zhao Pingan shook his head, suppressing the thought for now.

Now a real problem is at hand.

The system requires that 20 ships be built within 10 years.

Zhao Ping'an frowned.

"Ten years, 20 ships, two a year isn't too long..."

Shipyard expansion, equipment delivery, and worker training are all more than sufficient. At worst, the first three years will be dedicated to training and expansion.

Then they built four or five ships at once...

But is there enough time to overcome the reverse engineering challenges?

Although he only had a superficial understanding of the specific technologies, Zhao Ping'an began to analyze them one by one with the help of the system.

The first category includes those that can currently be manufactured.

A systematic review indicates that the current industrial production technology level in Northeast China has reached the level of the 90s.

After all, even with the large-scale import of advanced equipment and systems, followed by reverse engineering and personnel training, it still took five years to overcome many technical challenges.

The only limitation is personnel; otherwise, given that the system can purchase advanced equipment from 2016, surpassing the technological level of 2000 would be a piece of cake.

After all, the equipment dates back to between 2000 and 2016, and it's not performing at its full potential.

After reading the industrial assessment, Zhao Ping'an continued reading downwards.

Hull structure: 3000-ton steel hull.

Yes, the Dalian Shipyard built 10,000-ton ships back in the 1950s, so taking over the business won't be a problem at all.

Basic piping and cables – standard shipbuilding processes, no difficulty whatsoever.

Torpedo tubes – standard machining processes are now mature technologies.

Helicopter deck and hangar—the ship's auxiliary structures—were all packaged up by Dalian Shipyard.

The mechanical components of the diesel engine can be manufactured by Shenyang Heavy Industry and Shenyang Aerospace, given that they have already produced aircraft engines and possess the design blueprints.

Zhao Ping'an breathed a sigh of relief: "The hull is fine, and the mechanical parts can be gnawed."

Moving on to the second category, system evaluation requires 3 to 5 years of research and development.

The 76mm naval gun fire control system features a fully automatic loading and follow-up system.

Setting up a public relations team shouldn't be too difficult. If not, training a group of university students to work together on this should be possible within 10 years.

730 Close-In Weapon System (CIWS)

The mechanical components can already be manufactured; fire control and naval guns are being tackled in the same way.

C802 missile engine, small turbojet.

This can be handed over to the aerospace research institute; after all, the satellite has already been launched into space, so this shouldn't be difficult.

Diesel engine control system, electronic speed control + turbocharger.

This reverse engineering is what Shenyang Engine Factory does. They've done everything from the Type 59 tank to the T-72 and even the Type 2 fighter jet.

Combat command system hardware platform

We'll have to see if we can first train a group of software engineering undergraduates and push them to grow faster. But it should be enough in 10 years.

After reading this part, Zhao Ping'an breathed a slight sigh of relief. It was alright; he could manage most of it.

However, the system's analysis further down the chain of command sent a chill down Zhao Ping'an's spine.

The third category – those requiring long-term exchange of core components

SMARTS Mk2 3D radar, multi-beam phased array

There is a gap in the domestic market, and this area may remain a gap for decades to come. Historically, China only began to catch up after 2000.

C802 missile seeker, active radar seeker, miniaturized microwave devices

Electronic components are currently a blank area, and it is a long-term task. It would take at least 10 years to train a group of students, not to mention technicians and experts.

C802 data link, over-the-horizon target designation, secure communication

There's no point in even thinking about it anymore; he hasn't even been able to reverse engineer the infantry radio he exchanged for earlier...

FM90N air defense missile system

The launch system can also be replicated using a satellite launch system, with the guidance head being the same as before.

Combat Command System Software: Multi-sensor Data Fusion Algorithm

Pass, forget about it.

Core modules of electronic warfare systems: microwave devices + signal processing

Passport

Zhao Ping'an remained silent.

"These things... it's absolutely impossible to develop them ourselves in ten years, it would take at least a generation. So what do we do? You have to understand that 2021 is the year the Republic's navy will fully rise, with so much advanced equipment. If we ban technology and exchanges..."

Zhao Ping'an stared at the mission description for a long time.

"Complete the reverse engineering of 20 C28A frigates within 10 years."

He pondered those words repeatedly, and suddenly an idea flashed through his mind.

"Reverse manufacturing... must it be completely domestically produced, or...?"

He tried opening the system redemption interface and entered "C28A" in the search bar.

A long list of items pops up on the interface:

SMARTS Mk2 Radar (Complete Unit) - Redeemable

C802 missile seeker head (core module) - available for exchange

FM90N Air Defense Missile Guidance System (Core Module) - Available for Exchange

Combat Command System Software (Source Code Level) - Redeemable

Data Link Terminal (Core Module) - Exchangeable

……

Zhao Ping'an's eyes lit up.

He quickly turned around and read the task instructions again, word by word.

"Complete the reverse engineering of 20 C28A ships."

—It did not mention "completely domestically produced".

—It does not say "Disable the use of system components".

—It does not state that "core components must be developed in-house".

Zhao Pingan smiled.

"In other words, we build the hull ourselves, the machinery ourselves, and the power system ourselves."

Radar, guidance systems, and combat software—these are things we haven't been able to crack in ten years; we'll just use system-level trades as a temporary solution. Building 20 ships in ten years—that's entirely possible.

He recalculated the timeline again:

In the first and second years, the Dalian Shipyard expanded, building the first two ships to explore the possibilities.

In the third and fourth years, we will overcome the challenges of the fire control system, build two more ships, and increase the localization rate to 70% according to the system calculation.

From year 5 to year 8, domestically produced alternative radars were gradually used to replace existing ones, and large-scale manufacturing began, along with previous maintenance and upgrades.

In the 9th and 10th years, we made a final sprint to complete the mission.

"Ten years... 20 ships... no problem."

Zhao Pingan closed the system interface.

The words Commander Xiao had said when he left involuntarily came to mind.

"We can wait. After all, we've already waited for five years, so what's another three years?"

"Comrade Ping An, please remember this day. The Navy has waited far too long for it."

Ten C28A frigates. Commander Xiao, you don't need to wait any longer.

I've bought this fleet that can now silence any opponent!
