Global Wasteland: Unlimited Upgrades for Vaults

It is precisely because of this bug attribute that Sumo was willing to give up safety and rush in after seeing it in Ma Fei's shelter.

"Having the module is just the beginning. I need to completely self-produce the matching radar and fire control system within these ten days."

"At the same time, as soon as the next disaster strikes, go to sea and kill 500 aliens to upgrade the fifth-level shelter and make an advanced version of machine tools."

"With small and medium-sized machine tools, although it is still impossible to make missiles for the time being, rocket launchers can be made"

"At that time, I will use RPG fixed-point strikes at close range, and directly activate the launch module at medium and long distances, and use rocket launchers to scrub the ground!"

"Under this kind of firepower, I want to see who can still count on me!"

After a long sigh of relief from the suffocation caused by excitement, he put the moisture-proof cloth on the launch module again, and after returning to the third floor, Su Mo's mind had completely turned.

Before, I was worried about how to find a reason to sell the weapons to the tundra refuge, so as to ensure the absolute safety of the tundra refuge on the eve of the transfer.

But now it seems that there is no need to worry at all.

There are still many technology chains needed for shelters. In the fields that humans have researched, any system upgrades are too wasteful.

On the contrary, it is more cost-effective to trade with an official organization like the Tundra Refuge.

After groping and thinking for a while, he took out a notebook, and Su Mo began to plan all the things to be traded this time.

First things first...radar technology!

Radar is the transliteration of English radar. The overall translation means radio detection and ranging, so it is also called radio positioning.

In use, the radar emits electromagnetic waves to irradiate the target and receives its echoes, thereby obtaining information such as the distance, distance change rate, azimuth, height and other information from the target to the electromagnetic wave emission point.

The earliest appearance of radar can be traced back to the First World War on earth. For modern people who have accepted the explosion of knowledge and the rapid development of technology, it can be regarded as a product of the "ancient" era.

Therefore, in terms of principle and manufacturing difficulty, it is not a problem for ordinary people to make simple radars, as long as they have drawings and instructions.

As for the radar on the destroyer, there were actually not many options left for Sumo to choose.

On modern ships, generally higher-level ships are equipped with six types of radars, namely warning radar, guidance radar, phased array radar, over-the-horizon radar, fire control radar, and navigation and collision avoidance radar.

Among these six types of radars, for an 80-meter-long Class III destroyer, except that 3-5 radars for navigation and collision avoidance must be equipped to ensure safe navigation, the other five types can be equipped on demand.

"The warning radar used to distinguish between the enemy and the enemy is not needed. Even if they are human beings in the sea, they may be enemies. I will not let any strangers board the ship, so this item can be directly excluded to save the budget."

"The guidance radar used to guide the carrier-based aircraft to start and stop, and the over-the-horizon radar are even more unnecessary. Even if there is an aircraft now, I will not fly it!"

"So among the remaining options, fire control and phased array must be chosen!"

Emphatically circling the names of the two radars in the notebook, Su Mo began to slowly recall the information he had heard in a certain war show.

For shipborne phased array radar, the computer needs to control the feeding phase of each radiating unit on the array antenna.

Scanning is achieved by changing the radar antenna beam shape and pointing.

This kind of radar is the current mainstream shipboard radar, but the history of this thing's origin is not long.

It was also from the economic recovery in the 90s that it slowly increased.

Of course, as the mainstream, the technical level and manufacturing level must be much higher than other radars.

In comparison, the fire control radars that have been installed on ships since the 20s must have lower requirements.

"Phased array technology requires a lot. Even if I get the blueprint and want to manufacture it, I guess I will have to spend a lot of money to survive."

"If you really want to do it, it's better to use the fire control radar and the long-distance positioning radar directly for a rough implementation. Even if the accuracy is poor, I will recognize it!"

As soon as he slapped the table, Su Mo directly smeared a few times on the phased array radar with a pen, and chose to give up.

If you are poor, you will strike with precision, and if you are rich, you will have full coverage.

With an accuracy of less than one meter and an accuracy of less than 100 meters, Su Mo made a decision on the spot without hesitation.

"As long as I can make short-range ballistic missiles, the enemy will not have any gap at all in the center and within 100 meters"

"It's better to use all the saved materials and survival points to make ammunition. If you miss one round, I'll give you a hundred rounds for full coverage!"

Chapter 291 Weapon Preparation, Changes in Hope Village

In modern warfare, from small destroyers and frigates to large cruisers and aircraft carriers, these ships will not choose to carry short-range ballistic missiles, but choose anti-ship missiles.

The reason for choosing anti-ship missiles is simple.

The battleship is gone!

What is the emblem of a battleship?Big ship, giant gun and heavy armor!

Judging from the power of the mainstream anti-ship missiles in active service, more than [-]% of the models can only be said to be nowhere near the battleships of the ancient World War II.

If the battleship is still there, maybe Maozi's idea of ​​​​equipping the Kirov class with ballistic missiles can still be carried forward, but if it disappears, it will naturally become empty talk.

So battleships have such a great advantage, if they don't disappear, why are they equipped with missiles?

The reason why this line of thinking does not work is also very simple.

In modern times, due to the large number of precision components and complex technology of weapons, the cost per unit volume is far from what it was during World War II.

In the same way, the larger the displacement of the warship, the higher the cost.

According to the size of a battleship and an aircraft carrier, if a modern battleship with a displacement equivalent to an aircraft carrier is built, the larger size requires more powerful radars and more sophisticated instruments.

The cost of its hull itself is not necessarily cheaper than that of an aircraft carrier, and its huge number and variety of missiles are completely sufficient to compete with the overall cost of an aircraft carrier.

In addition, since the ships are all sailing on the sea, affected by the curvature of the earth, the ability of the shipboard radar to detect surface ships is actually relatively weak.

Without the cooperation of air and sky, you have to drive close enough to use missiles to attack each other!

To drive such an expensive battleship over and engage in missile exchanges with the opposite side at close range, even a few big hooligans do not have the funds and courage to display it.

Therefore, as battleships withdraw from the battlefield and the "skin" of various ships becomes thinner and thinner, it is meaningless to choose large-yield missiles. Even heavy-duty anti-ship missiles are only 500 kilograms.

Moreover, in modern warfare, ballistic missiles have better vehicles, nuclear submarines, which are convenient and stable.

On the other hand, the launch environment for ballistic missiles is very poor.

If a hot start is adopted and the missile is launched directly on the deck, it is very likely that the electronic equipment of the entire ship will be exposed to the tail flame of the missile.

If a cold launch is adopted, the missile must be ejected to a very high position before it can be ignited, and the swing of the ship platform will seriously affect the missile accuracy, which will eventually greatly weaken the accuracy of the missile.

This has led to the inevitable result of the development of technological weapons.

But if the situation is changed to the ocean of wasteland, when considering this kind of problem, it is necessary to fully integrate the actual situation.
