After the modification plan was determined, everything was carried out in an orderly manner in the shipyard of Jiangnan Shipyard.

However, at this moment, Qin Chuan was also thinking about the issue of air defense weapons for the modified maritime police ships.

The 52C destroyer uses the 730 close range gun defense system.

And this system has not been dismantled by the navy, it is reserved for the maritime police.

This close range defense system is incomparable to the 1130 close range guns used by naval aircraft carriers and state-of-the-art destroyers.

But it is also the most advanced among the active law enforcement vessels of the maritime police.

Previously, Qin Chuan also believed that the 730 close range anti-aircraft gun was sufficient, so he kept it without making any modifications.

But he didn't expect the system to directly convert retired destroyers into nuclear powered electromagnetic railgun law enforcement ships!

In this way, the 730 proximity defense system seems particularly out of place!

However, according to international practice, air defense missile systems such as Haihongqi cannot be used on coast guard ships.

The only option left for Qinchuan to choose from is the close range artillery system.

"Do we need to provide the 1130 close range gun defense system for the modified maritime police ship's aircraft carrier?"

For a moment, Qinchuan fell into a dilemma.

After all, the reason for the retirement of the 52C destroyer is that its equipment is somewhat outdated.

If the 52C destroyer is equipped with the 1130 close range defense system, it is likely that the Navy will not retire it for use by their maritime police.

So Qin Chuan's application for a 1130 close range defense system is unlikely to be approved.

"Instead of sticking to traditional close range gun systems, it's better to develop an electromagnetic anti-aircraft gun using the electromagnetic railgun technology provided by the system!"

"And according to the projectile speed of electromagnetic anti-aircraft guns, even hypersonic missiles cannot intercept them!"

After his thinking diverged, Qin Chuan suddenly had an idea.

Hypersonic weapons have a much faster flight speed than air defense missiles.

So when it comes to intercepting incoming hypersonic weapons, countries are all very troubled.

There is currently no mature solution available.

But the projectile fired by the electromagnetic gun has a speed far exceeding that of close range guns and anti-aircraft missiles, and it has a unique advantage when used as an interception missile.

Based on the mature electromagnetic railgun technology provided by the system, Qinchuan is preparing to develop an electromagnetic anti-aircraft gun that can intercept hypersonic weapons for the modified coast guard ship!

And for Qin Chuan, there is no technical obstacle to this idea.

He only needs to slightly modify the electromagnetic railgun and develop an air defense fire control system to match it!

After the idea was determined, Qin Chuan immediately took action.

For over a month in a row, he was solving the fire control algorithm problem of electromagnetic anti-aircraft guns intercepting hypersonic weapons.

In this regard, he even anticipated the enemy first, taking into account the ballistic missile maneuvering and trajectory transfer technology that the enemy had not yet mastered.

Generally speaking, it is only when a country develops a new type of missile that other countries will develop a targeted new type of anti missile system.

However, Western countries have not yet mastered the maneuvering and orbit changing technology of hypersonic weapons, so Qinchuan first developed an interception system.

He is completely blocking the enemy's development path in this regard.

After all, you haven't successfully developed a maneuverable hypersonic missile yet, and other interception systems have already been developed.

Are you continuing with research and development?

Still not developing it?

And for maritime police, there is no problem of wasting research and development resources.

Anyway, the technology is ready-made, and it's not a big deal to develop it and compete with the navy left and right!

Hard work pays off, and after nearly two months of hard work, the problem with electromagnetic anti-aircraft guns has been successfully solved.

And it was redesigned by Qinchuan onto the modified maritime law enforcement ship.

The final puzzle was pieced together, and the modification work of the new maritime police ship entered an accelerated stage.

At present, all the equipment to be replaced on the ship has been dismantled, and the remaining work is the installation and commissioning of new equipment.

Three months later.

The modification work of the maritime police ship has entered the final stage.

From dismantling to installation, it took a total of five months, from front to back, to paint the bow and hull of the new maritime police vessel.

"Everything has been modified?"

After arriving at the shipyard's dock, Qin Chuan asked as he looked at the newly renovated coast guard ship.

"General Qin, all the modification work has been completed, but the hull number and paint of the Coast Guard ship require your final signature for confirmation!"

Zhang Bin, the person in charge of the specific modification project in the shipyard, told Qin Chuan.

"1601!"

Qin Chuan wrote the hull number of the new maritime police ship and signed his own name.

The maritime police ship's hull number is generally composed of four and five digits.

The four digits belong to the direct management of the Maritime Police Bureau, while the five digits are under the jurisdiction of the local Maritime Police Sub bureau.

For example, the modified new maritime police ship with hull number 1601 represents that it is directly managed by the Maritime Police Administration.

At the same time, the first digit of its hull number is 1, indicating that it belongs to the First Squadron.

The second digit is 6, representing a drainage tonnage of 6000 tons.

And the following 01 is the number.

After Qinchuan named the hull number and signed for confirmation, the bow of the Coast Guard ship was immediately painted and the hull number was drawn.

"Tomorrow May 1st, we will officially conduct the 1601 underwater sea trial!"

Qin Chuan issued an order.

Generally speaking, coast guard ships converted from retired warships do not require sea trials.

However, due to significant modifications made to the new maritime police ship, all aspects including power, propulsion systems, and weapons and equipment have been innovated.

So its navigation performance, speed, heading stability, and weapon equipment performance parameters all need to undergo a series of tests!

Only after the sea trial is completed can it be officially put into service!
