Ye Han tilted his head and stared at the main screen with a look of despair.
It's not that his mental endurance is too poor, but that the situation he's facing right now is really complicated. When he thinks about the alien fleet, his temples keep beating.
Ever since he received the order from Beiyuezhou, Ye Han began to observe this alien fleet. All his thoughts were on how to complete the task, but this task was too difficult. One against eighteen, the strength of the enemy and ourselves was completely different.
A grade.
In order to complete the mission, Ye Han racked his brains and thought of ways to stop the enemy all day long.
Sneak attack?
no!
Space is unobstructed, and there is no way for the Leishan to conceal its tracks. Now that the enemy and we still have several days to travel, the Leishan is already being targeted by aliens, and there is no chance of getting close, so a sneak attack is out of the question.
Guerrilla?
No way!
Guerrilla means both traveling and attacking. If you can't get close to the enemy's side, you'll just travel without attacking, and you'll still be stuck with the same problem.
Using asteroids?
This works, although it is used more often, but a good method is a good method.
Ye Han thought well, but aliens have fallen into pits many times, and no matter how short of memory they are, they still learn lessons. Leishan is still far away from the alien fleet, so aliens should be prepared in advance. Whenever they encounter
Asteroids should be avoided in advance, and they would rather go around the asteroid than give Leishan a chance.
Can Ye Han, that alien who calls me a pain in the ass, still be able to have a good fight?
No matter how scolded or unhappy, 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.
Desperately?
This is a good idea. At the very least, it can destroy a few enemy transport ships. However, the aliens have eighteen warships. The lives of my family are precious, and Ye Han cannot send the Leishan into a pit of fire.
If you can't get close and still want to attack, then only the range of naval guns and missiles is enough. The former has enough range but the accuracy is too poor. Only missiles have a chance.
But it's just a trace. The enemy ship's patrol range is very large, and it has deliberately added a certain distance in the direction of Leishan. Even the long-range missile with the longest range cannot reach the enemy's transport ship... Yes, it is a transport ship.
This battle is not to destroy the enemy's warships, but to destroy the enemy's supplies. Transport ships are naturally the primary target.
Of course, it would be even more perfect if you can kill the enemy ship easily.
With an idea in his 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 modify the existing long-range missiles so that they could function at ultra-long distances.
There are many factors that limit the range of a missile, the most important of which are three. One is 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 other is the fuel issue, which determines
It refers to the range and speed of the missile; finally, it is the direction when the missile is launched. When it is launched, it is slightly off, and after it flies far, it will be offset by dozens or hundreds of kilometers.
The conditions on the ship are limited, and the equipment on the missile is relatively sophisticated. The modification cannot involve sophisticated electronic equipment. Therefore, there is no room for improvement in the first direction, and it cannot be moved even if it is wanted to.
The issue of fuel is somewhat complicated. Generally speaking, missiles can be divided into solid fuel and liquid fuel in terms of fuel form. Both have their own advantages and disadvantages. However, at the military level, it is recognized by all countries that solid fuel is superior to liquid fuel.
However, nothing can be generalized. The disadvantage of solid fuel is that it has to be burned in one breath when ignited. The combat distance of space battleships is often beyond imagination. The missile must be propelled in sections. If solid fuel is used, it can only be designed into a multi-stage structure and equipment.
Costs and maintenance costs are bound to rise significantly.
Liquid fuel is different. It can adjust the amount of fuel entering the fuel chamber according to the actual situation, and can even shut down and restart the engine at any time. For space battles that often span hundreds or thousands of kilometers, the segmented propulsion of missiles is extremely important.
of practical significance.
Both missiles are indispensable and important equipment on space battleships, but the military has optimized and selected them based on their respective characteristics.
Solid fuel missiles are mainly short-range air defense missiles that do not have high range requirements. Their common feature is that they have a short range and do not require staged propulsion.
However, the range requirements are relatively high and those that require segmented maneuvers are all liquid fuel. Most of the medium and long-range missiles used by the space fleet are liquid fuel.
It is not that solid fuel cannot be propelled in stages, 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 fuel, but the number of equipment is not large.
For example, the Shenyu missile has a unique structure. The first stage is only to deliver the missile to the target, and does not require segmented maneuvers. Therefore, except for the most original model that uses liquid fuel, all subsequent improved models are
Switch to solid fuel.
By the way, Yuyu missiles are always solid fuel.
If the Leishan wants to kill the enemy's transport ship, its only option 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 this really the case?
As we all know, the temperature in space is very extreme and is lower than the freezing 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 without waiting for the fuel to freeze.
But this time is different. The distance between the two sides is too far. The missile is expected to fly for about ten days. In such a long time, the fuel tank will freeze before the missile hits. Even if it flies to the place, it will not ignite.
Not as good as cannonballs.
Therefore, the first step in modifying the missile is to install a heating device in the missile's fuel tank to ensure that the fuel does not condense.
Don't think that installing a set of heated armor is easy. Missiles are very sophisticated cutting-edge weapons and cannot be modified casually. For this matter, Ye Han specifically contacted Bei Yuezhou. First, he asked Bei Yuezhou to
Provided technical support, summoned the best maintenance personnel on the ship, and worked hard for two days and two nights, and finally completed the modification of a missile... Yes, it was one!
One missile was better than none at all. Ye Han was more careful, cautious and cautious, and tested it several times. It was not until the missile passed all tests that he finally breathed a sigh of relief.
Then came the process of injecting fuel and installing the nuclear warhead. After a series of procedures, the missile finally completed all the procedures and was ready for launch.
