One Thousand Two Hundred and Eighty-Six Overcoming Difficulties

A few days later, Leishan.

Ye Han tilted his head and stared at the main screen, looking hopeless.

It was not that his psychological endurance was too poor, but that the situation he was facing was too complicated. When he thought of the alien fleet, his temples kept throbbing.

Ever since receiving the order from Beiyuezhou, Ye Han began to observe this alien fleet, and all his thoughts were on how to complete the mission, but this mission was too difficult, one against eighteen, the strength of the enemy and us was completely different.

In order to complete the mission, Ye Han racked his brains and thought about how to stop the enemy all day long.

A sneak attack?

No way!

There was no shelter in space, and the Leishan had no way to conceal its tracks. Now the enemy and us still had several days of sailing, and the Leishan had been stared at by the aliens, and there was no chance to get close, so a sneak attack was naturally out of the question

Guerrilla?

No way!

Guerrilla warfare, both warfare and attack, if you can't get close to the enemy, it's just warfare without attack, and you're stuck with the same problem.

Use asteroids?

This is possible, although it's used more often, but a good method is a good method.

Ye Han's idea is not bad, but the aliens have fallen into the trap many times, and even if they don't remember, they know to learn lessons. Leishan is still far away from the alien fleet, and the aliens are ready in advance. Whenever they encounter an asteroid, they will avoid it in advance, and would rather go around the asteroid than give Leishan a chance.

Ye Han was so annoyed. Can the damn aliens fight well?

Cursing is fine, and being unhappy is fine, but the mission still needs to be completed, but judging from the other party's behavior, it is absolutely impossible to get close to the fleet.

Fight with all your strength?

This is a good idea, at least it can kill a few enemy transport ships, but the aliens have 18 warships, and the lives of their own people are precious. Ye Han can't send Leishan into the fire pit.

Since we cannot get close but want to attack, then only the range of ship guns and missiles is enough. The former has enough range but poor accuracy, so only missiles have a slight chance.

But it is only a slight chance. The patrol range of the enemy ship is very large, and they deliberately add a distance in the direction of Leishan. Even the long-range missiles with the longest range cannot reach the enemy's transport ship... Yes, the transport ship. This battle is not to destroy the enemy's warships, but to destroy the enemy's supplies. The transport ship is naturally the primary target.

Of course, it would be even better if we can kill the enemy ship.

With an idea in mind, Ye Han immediately started to implement it. The first problem he had to solve was that the range of the missiles was not enough. He had to find a way to transform the existing long-range missiles so that they could play a role at a super long distance.

There are many factors that limit the range of missiles, and the three most important ones are: the detection and locking capability of the missile itself, which determines the activation distance when the missile flies near the target, as well as the final hit rate; the second is the fuel problem, which determines the range and speed of the missile; and finally the direction of the missile when it is launched. If it is slightly off during launch, it will be offset by tens or hundreds of kilometers after flying far.

The conditions on the ship are limited, and the equipment on the missile is relatively sophisticated. The transformation cannot involve sophisticated electronic equipment. Therefore, there is no room for improvement in the first direction, and it cannot be moved even if you want to.

The fuel issue is somewhat complicated. Generally speaking, missiles can be divided into two types according to the fuel form: solid fuel and liquid fuel. Both have their advantages and disadvantages, but at the military level, solid fuel is recognized by all countries as superior to liquid fuel.

However, nothing can be generalized. The disadvantage of solid fuel is that it must be burned out in one breath when ignited, and the combat distance of space battleships is often beyond imagination. Missiles must be propelled in stages. If solid fuel is used, it can only be designed into a multi-stage structure, and the equipment cost and maintenance cost will inevitably increase significantly.

Liquid fuel is different. It can adjust the amount of fuel entering the fuel chamber according to the actual situation, and even shut down and restart the engine at any time. For space battles of hundreds or thousands of kilometers, the segmented propulsion of missiles has extremely important practical significance.

Both types of missiles are indispensable and important equipment on space warships, but the military has optimized and selected them according to their respective characteristics.

Solid fuel missiles are mainly short-range air defense missiles with low range requirements. Their common characteristics are short range and no need for segmented propulsion.

Liquid fuels are used for missiles with high range requirements and segmented maneuvers. Most of the medium and long-range missiles used by space fleets are liquid fuels.

Solid fuels are not impossible to propel in segments, but the technology is too troublesome, and the production cost is a big problem that cannot be solved.

Of course, nothing is absolute. There are also models of long-range missiles that use solid fuels, but the number of equipment is small.

For example, the female fish missile has a unique structure. The first stage is just to send the missile to the vicinity of the target, and there is little need for segmented maneuvers. Therefore, except for the most original model that uses liquid fuel, all subsequent improved models are replaced with solid fuels.

By the way, the Yuyu missiles are always solid fuel.

The only option for the Leishan to kill the enemy transport ship is long-range missiles, but the long-range missiles on the ship are all liquid fuel.

Long-range missiles are designed in this way, and using liquid fuel does not seem to be a problem, but is it really the case?

As we all know, the temperature in space is very extreme, even lower than the solidification temperature of liquid fuel. When the missile is not launched, the temperature inside the ship can prevent the fuel from freezing; after the missile is launched, it hits the target before the fuel freezes.

But this time it was different. The distance between the two sides was too far. The missile was expected to fly for about ten days. With such a long time, the fuel tank froze before the missile hit the target. Even if it flew to the target, it could not ignite. It was worse than a cannonball.

So the first step in modifying the missile was to install a heating device for the missile's fuel tank to ensure that the fuel did not condense.

Don't think that installing a set of heating armor is simple. Missiles are very sophisticated and cutting-edge weapons. They are not something that can be modified casually. For this matter, Ye Han specially contacted Beiyuezhou. First, he asked Beiyuezhou to provide technical support, and then he summoned the best maintenance personnel on the ship. After two days and two nights of continuous fighting, he finally completed the modification of a missile... Yes, one!

One is better than nothing. Ye Han was careful and cautious, and tested it repeatedly several times until the missile passed all the tests, and finally breathed a sigh of relief.

Then it was to inject fuel and install the nuclear warhead. After a series of procedures, the missile finally completed all the procedures and was ready for launch.
