When China built the 071 dock landing ship, it was rushing to save as much as possible, all kinds of equipment and materials can be saved, and even some non-critical equipment is used to civilian standards.

Although she has a body size of 20,000 tons, the structure is actually relatively simple, and the cost is not even half of the 6,000 tons of 052D.

The radar and electronic systems are relatively weak, and the near-defense missile is designed to leave space, but it is not installed in the actual construction, and the scheduled Hongqi 7 has also been canceled.

Not to mention the latest 1130, the 730 is not available, and the improved AK22 like the Type 630 missile boat is used.

The 76-mm guns of the frigates used for the naval guns, the engine is also diesel, and the maximum speed is 22 knots.

Mu Feng watched Kunlun actually test various equipment, and at the same time seriously thought about her upgrade plan.

I don't care much about resource consumption now, so I don't need to care too much about the cost, and the only purpose is to improve Kunlun's ability as much as possible.

Kunlun has a 20,000-ton hull, even if you take the full set of equipment of 055, you can put it down.

However, the set of electronic, radar, and vertical hair equipment of 055 takes up too much space, and if it is transplanted directly, the functions of the dock landing ship itself will be compressed.

The Kunlun is its only dock landing ship, and the purpose of the renovation is to enhance its own functions as much as possible, and he definitely does not want a larger 055.

There is a specialization in the art industry, and if you can do everything, you may not be good at everything.

My own transformation idea should be to restore what it has reduced due to cost considerations, and delete things that have nothing to do with personnel.

The modified state of the San Antonio-class dock transport ship of the same type in the United States can also be used as a reference scheme for the Kunlun transformation.

By the evening, Mu Feng basically understood Kunlun's ability, and the transformation plan was basically confirmed, so he took Kunlun back to the port area.

I went to the restaurant for dinner first, and by the way, I introduced myself to other ship girls in the port area.

After dinner, Mu Feng took Kunlun to the second floor of the apartment building to arrange a room for her.

After entering the door, Kunlun took a look at the environment of the room, in addition to the lack of kitchen and refrigerator, it is almost equivalent to a modern single apartment, all kinds of modern facilities are readily available, and he said unexpectedly:

"Commander, is this the dormitory of our fleet? There is only one queen bed in this room...... That is, am I the only one living in this room? ”

Mu Feng smiled and nodded: "Except for the little 22 who are not used to being alone, everyone else is one person in one room, aren't you used to living alone?" ”

"It's not!" Kunlun hurriedly shook his head, "No, I think that as a dormitory, this condition is a bit too good, I originally thought it would be a four-person or six-person collective dormitory." ”

"The conditions here are not good, I can only say that they are average......" Mu Feng looked at the environment in the room, "The apartment building should indeed be upgraded......"

Kunlun blinked: "The air conditioning, independent bathroom, heating, desk, and large balcony in this dormitory are already available, and they are still upgraded?" How else can I upgrade? ”

Mu Feng thought for a while: "For example, computers, network cables, wall-mounted TVs, freezers, projectors, adding some potted plants, fabric sofa sets, wine cabinets, coffee tables, wool carpets and other facilities."

"Finally, upgrade the beds, tables, chairs, and lamps, preferably in different rooms, and redecorate them with different decoration styles according to the preferences of the shipwreck who lives......"

Kunlun was completely speechless: "Commander, stop, stop, is this really the army's dormitory?" ”

Mu Feng waved his hand: "What's this?" I will do no one to you! I felt that this room was too small and the upgrade potential was limited, so I was going to build another apartment building and expand the individual rooms......

"Forget it, don't talk about it, just do it yourself, I've basically determined your transformation plan, you go to bed and lie down, relax, keep your heart in touch with me, and leave the rest to me."

"Forehead......" Kunlun nodded a little confused, and obediently went to the bed and lay down according to what Mu Feng said, "Commander, I'm ready, you can start......"

"Hmm." Mu Feng sat down on the side of the bed, entered the system to find Kunlun, and entered the hull transformation interface.

The scale of the transformation of Kunlun is relatively large, because to change the hull, a small scientific research program is needed, and the scientific research consumption is not large, only 300 points.

Mu Feng directly consumed the existing scientific research points to complete this plan, and then applied it to the hull of Kunlun, and there are other Type 071 dock landing ships in the future, which can be directly applied.

The specific transformation plan is, first of all, the practice of the ship's transformation, which compresses the crew compartment that will not be needed in the future to a minimum.

Then it was to replace the power system, the Kunlun Mountain originally used a combined diesel engine, with a total output of only 47,000 horsepower and a maximum of 22 knots.

The stern looks like a square butt, but in fact, it is to facilitate helicopter take-off and landing, only the surface part of the water is flat, and the part below the water surface is actually a round stern of the cruiser.

Mu Feng replaced her with four new gas turbines, and the power output was increased to 210,000 horsepower, which was to prepare for the electromagnetic cannon on the ship, and at the same time directly all-electric transformation.

If you want to give the dock landing ship a gas turbine, you must also carry out an all-electric transformation.

Gas turbines and aircraft engines are based on the same principle, and the blades rotate after heating and expanding by inhaling air, so they need relatively large intake and exhaust channels.

If it is not fully electric, the gas turbine needs to be placed in the middle of the hull, so that it is convenient to connect the propeller spindle of the hull through variable speed gears to reduce energy loss.

However, in this way, the intake and exhaust channels of the gas turbine must be placed in the middle of the hull, running through the entire upper layer of the hull, which will affect the dock compartment inside the Kunlun hull.

This problem is the same as that of aircraft carriers, conventionally powered aircraft carriers need to use gas turbines, and they can only be placed on the side like the Queen Elizabeth class, so that the intake and exhaust channels can not affect the hangar.

But if you want to put it on the side, you can only use an all-electric propulsion, not a conventional transmission.

Therefore, Mufeng's placement of the four gas turbines in Kunlun is to put two on each side of the hull, and the air intake and exhaust channels are arranged close to the hull shell, so as not to affect the dock compartment in the middle.

The Kunlun's hull line was originally designed according to a low speed of 20 knots, but now that the gas turbine is replaced, it has to adjust the hull line if it wants to run fast.

Since the hull was to be adjusted, Mu Feng simply lengthened the Kunlun's hull from the rear, extending the hull from 210 meters to 230 meters, and expanding the volume of the dock as a whole.

After adjusting the overall structure of the hull, the internal compartments of the hull were adjusted.

The dock compartment of the dock landing ship is roughly divided into three parts, and the large dock compartment in the rear accounts for about two-thirds of the hull, which can put four fast landing craft to carry other land combat vehicles and personnel.

Directly in front of the large dock, about a third of the length of the hull, is a multi-storey warehouse for vehicles, with the lowest level being a tank armored garage and other light military vehicles such as off-road vehicles above.

These tanks and armored vehicles usually enter the garage directly through the door on the side of the hull, and when used, they are transported from the garage through the door to the landing craft in the large dock.

Then the dock was filled with water, and the landing craft rushed directly to the shore with these vehicles.

The overall structure and transportation method of this dock landing ship cannot be changed, and Mu Feng only because the hull is extended, so the dock cabin is also moved backward to lengthen the multi-storey vehicle warehouse in front.

Amphibious armored vehicles can be mixed with landing craft in large dock cabins, and special vehicle warehouses in front are used to place equipment such as main battle tanks and off-road vehicles that cannot wade in water.

Above the large dock, the rear half is a platform for operating two helicopters at the same time, the front half is an indoor hangar for four helicopters, and in front of the hangar is the bridge.

Mufeng moved the helicopter platform back with the extension of the hull, and the overall area remained the same.

The hangar was expanded to the front and rear, and all the control function compartments under the bridge that were of little use to the ship's mother were opened up and replaced with an all-access helicopter hangar.

In this way, the internal adjustment is completed, and finally the outside of the hull.

First of all, the bow of the ship's guns, the Kunlun's 76-mm guns are the level of frigates, which are quite small compared to the size of the battle cruisers, and they are located relatively backward.

Mu Feng moved the naval gun forward to a position similar to 055, replaced it with 055's 130mm naval gun, and after Neptune's electromagnetic cannon research plan was completed, he replaced it with an electromagnetic gun with the shield ship.

The structure under the turret of the larger caliber main gun may squeeze some light vehicle hangars, but does not affect the tank armored garage on the ground floor.

There was an empty platform behind the ship's guns, which was originally intended to place Haihongqi-7 close-in defense missiles, but it was saved when it was actually built.

Now that the guns have been moved forward, and the secondary platform in front of the bridge is added, a space more than 30 meters long and 28 meters wide has been vacated.

Mufeng leveled the place and then installed 4 sets of 32-unit vertical launch systems.

This vertical hair uses a 3.3-meter-deep version, only such a height will not affect the cabin below, specially used to put four medium and short-range anti-aircraft missiles in one pit and four bombs, a total of 128 pieces.

The 20,000-ton hull is really quite wide, and there is still quite a lot of room for 4 sets of vertical hair.

Mufeng installed 4 sets of a total of 16 YJ-12 anti-ship missiles, which were not many in number, but only defensive in nature.

In the end, the ship's radar fire control system was all upgraded, and the mast was replaced with the integrated mast of 055.

All four AK630s were replaced with 1130, and four sets of Hongqi 10 anti-aircraft missiles were installed.

In this way, the first round of transformation of Kunlun is basically completed.

Mu Feng asked the system to test his own transformation plan and found that the ship's center of gravity was a little off.

Immediately readjusted the equipment and counterweight according to the system prompts, and let the system confirm it again, until there was no problem at all, and finally ordered the transformation to be confirmed.

It costs a total of 5,000 units of resources and takes 1 hour.

Mu Feng watched Kunlun enter a dormant state, and glanced at the overall data of the transformed Kunlun again.

The full load displacement has been increased from 20,000 tons to almost 30,000 tons, with a length of 230 meters and a width of 28 meters, which is only a little thinner than the Veneto-class battleships.

The powertrain has a maximum output of 210,000 horsepower and a design speed of 35 knots, with a margin.

The large dock can accommodate 10 ZTD-05 amphibious assault vehicles while loading 4 150-ton air-cushion landing craft.

Without landing craft, this large dock can hold 40 ZTD-05 amphibious assault vehicles.

The proportions of landing craft and amphibious assault vehicles can be mixed and matched.

The specialized heavy armored garage in the rear has been expanded, and the sin can hold 20 99A main battle tanks, or the same number of ZTD-05 amphibious assault vehicles, which can also be mixed and matched.

In addition to this, the light garage on the upper level can hold dozens more off-road vehicles.

The helicopter hangar above the large dock can be expanded to accommodate up to 8 helicopters, and if necessary, 4 more helicopters can be moored on the helicopter operating platform.

Mu Feng originally held a straight 20 and didn't know who to use it, but this time he directly installed it for Kunlun, which should be able to play the maximum role of this new aircraft.

All tanks, armored vehicles, helicopters, off-road vehicles, hovercraft, and landing craft are reserved for Kunlun, and when it comes to specific use, which aspects of equipment need to be replaced through supplies.
