As a time traveler, Xu Jie realized the importance of guided weapons very early. As a naval time traveler, after becoming familiar with the guidance modes of World War II and later generations in history, Xu Jie used red-headed documents as general equipment. The guided weapons research department under the ministry put forward ideas one by one, thus creating a precedent for China's guided weapons. China's first-generation air-to-sea (ground) guided weapons are divided into three types. The simplest is Guided bombs, the second type is gliding guided bombs, and the third type is the most complex anti-ship missile. The guidance methods also range from the simplest optical targeting to radio guidance, to the later radar guidance and the legendary tall TV guidance. and infrared guidance. Of course, the later hits are more of a technical reserve, and their use is still very limited.

In fact, various guidance methods have already taken shape in World War II. For example, radio guidance was used on Fritz X bombs and hs293 missiles. There is also a model of hs293 that uses wired guidance, but in the end It's just not put into production. There are also improved versions of the TV-guided hs293 missile. As for the so-called high-end infrared guidance, the bat-type automatic bottom-seeking gliding bomb made by the Americans uses an infrared seeker, but because it entered the war late, there are not many The results are not very good.

The most common guidance method in Germany during World War II was naturally radio command guidance. The principle is very simple. It is equivalent to a person using a remote control to operate an aircraft and hit the target. This seems simple, but in actual operation That's not the case. This guidance process involves three objects, one is the target, one is the aircraft, and the other is the bomb or missile itself. These objects are constantly moving, and the speed of the aircraft is about 400km per hour. The speed of the battleship is also about 30 to 40km, or even higher. The movement of the bomb is even more troublesome. There is an initial speed, gravity acceleration, resistance and wind direction. When these factors are combined, who knows what the bomb will do. How to fly. Calculated based on the 8km throwing distance of the Fritz It is conceivable that an important reason why the DO217 was able to sink Rome by dropping guided bombs was that the Italians mistakenly thought it was an Allied aircraft. Therefore, no evasive measures were taken.

The Germans are very aware of the difficulty of this kind of attack, so they take a variety of measures to maintain accuracy when performing combat missions. If you want to control the bomb, you must first find the bomb itself, so the Germans after Fritz x bomb A light-emitting tube is added to the bottom to locate the bomb. Secondly, the attack method of the Fritz bomb is very special. It is dropped by a DO217 and guided by another bomber. This seems troublesome but is actually It is necessary because the bomber used for guidance has a fixed course and speed. In other words, the original three dynamic variables have become two! The American Norton bombsight is also used through the autopilot. To assist aiming. In this way, errors can be reduced, and special optical sights can be used to aim and control bombs to attack.

As for the issue of information transmission, the Germans equipped the Fritz

Guidance. This guidance device requires two strips of approximately 3

Only a 0km signal line can ensure that the hs293 missile can launch an attack at a distance of 12 to 18km. The biggest advantage of wired guidance is that it is almost impossible to be interfered with during signal transmission, and the signal is relatively good. The disadvantage is obvious, 30km wire is not cheap. And

It also weighs a lot.

Using visual aiming plus radio command guidance is the most convenient, but it is also a aiming method with large errors. The accuracy of aiming depends very much on the level of the operator. And the ability to process data is very weak. Considering that China can obtain the United States and

With British technology, even at a historical level, China can fully obtain centimeter-wave radar. It can locate the opponent's position more accurately, and its anti-interference ability is also relatively strong. In addition, during World War II, the Americans also used it on battleships.

Equipped with electromechanical computers for processing data. For example, those used by the U.S. Navy

The mk1 electromechanical computer can track the target's distance change rate without any delay. In terms of accuracy, it is much better than simple visual aiming. Americans also have signal generators and receivers, so they use radar.

Discover and track targets using electromechanical or electrical

Using a subcomputer to settle information, using radar and radio command guidance should be the most realistic guidance method. Of course, if the Germans go against the odds and come up with an electronic jammer that far exceeds history, Xu Jie would not mind using wired guidance, right?

Bring more wires? It's not a big deal.

In short, this missile system consists of three parts: radar, computer, signal transmitter, and missile. Its combat range is temporarily set at about 15km, as long as it can avoid anti-aircraft artillery attacks. The radar must use anti-jamming and frequency hopping technology

.The precise fire control distance should be more than 25km. Is it possible to achieve these technologies in this plane?

Xu Jie is not very worried about the requirement. Historically, German fire control radars have achieved direct frequency hopping in three frequency bands. And even in the face of chaff or interference ropes, radars equipped with anti-jamming equipment can still

Finding the target from a chaff cloud whose reflection intensity is nearly 20 times higher than that of the target. Of course, this requires excellent training of radar operators.

As for the power of the missile? Considering that the targets we have to face in World War 2 are thick-skinned battleships and armored aircraft carriers, its power is at least equivalent to an 800kg bomb. To deal with targets such as destroyers or cruisers, 500kg can be considered

Semi-armor-piercing warhead. This weight seems to be heavier than that of many anti-ship missile warheads during the Cold War, but don’t forget how far the latter’s range is. At this time, because there is no need to consider the issue of long-range air defense missiles, so

The range can be reduced to a very low level.

If you feel that the power is not enough, continue to install a larger warhead, such as the 1,400kg bomb installed on the Fritz X bomb in history. Then it is obviously not possible to install it on an anti-ship missile.

The rocket engine thrust at that time was too low, so only guidance bombs or gliding bombs could be used. Such powerful bombs would also perform well when attacking ground targets.

The Guided Weapons Research Institute of the General Armament Department of China is currently developing three types of air-to-sea guided weapons, numbered AS1, weighing 900kg and equipped with a 500kg warhead, with a range of about 15km and a speed of 600 to 900km per hour.

Anti-ship missiles and guided bombs numbered LT-1

And a glide bomb version with added glide wings. The warhead of this glide bomb is a semi-armor-piercing warhead weighing 1,200kg. When thrown from an altitude of about 3,000 meters, it can destroy the horizontal armor of almost all known warships.

At the same time, in order to attack ground targets, it may also be equipped with anti-bunker warheads or high-explosive bombs in the later stage.

After having a bomb, there must also be a carrier aircraft. According to the historical bomb load of World War II bombers, the maximum bomb load of a general medium bomber is about 2.5 tons. Of course, if you reduce the fuel, the bomb load will be greater.

A bit higher. As for the carrier aircraft,

question, considering that this aircraft is not required to dive at a large angle, and places more emphasis on range and bomb load. Therefore, after careful consideration, Xu Jie decided to use the American bombers from World War II in history as the Chinese anti-ship missile.

The blueprint for machine design.

The more representative American medium bomber in the middle and late stages of World War II is the B25J bomber. This aircraft is equipped with 12 M2 large-caliber machine guns and has 4,600 rounds of ammunition. It can also have 4,000 pounds of bombs and 4,300 liters of fuel.

A combat radius of 685 nautical miles! Under such a heavy load, the speed of this aircraft is relatively slow, and the maximum speed can reach more than 470km at an altitude of 15,000 feet.

This performance is already quite good. Some people may use the more than 6,000 pounds of bomb load of late-model bombers such as the J88-A14 as an issue. But in fact, the opponent has exchanged light armaments and sacrificed fuel load in exchange for a large bomb load.

Quantitative. And

Under normal circumstances, the bomb load of the JU88A17 torpedo attack aircraft is only two torpedoes weighing about 2,200 pounds. But in detail, the performance of the B25J is even better. Let’s talk about armaments first. The later JU88 bombers usually have self-defense

Wu

The weapons are two 7.92mm machine guns and two 13mm machine guns. This is incomparable with the fire hedgehog-like self-defense firepower possessed by the B25J bomber. As for the conversion between internal oil and bombs, you can refer to such a standard.

When ju88 carries a 2400kg bomb, its internal fuel is 1221kg. When it carries a 1500kg bomb, its internal fuel is 2105kg. Overall, the total carrying capacity of ju88's internal fuel and bombs is about 3600kg.

The B25J bomber's full internal fuel capacity is about 3200kg, and a 4000-pound bomb can also be converted into 1800kg. The total amount of bombs and internal fuel is about 5000kg. It is one level higher than the JU88A series. (Note that the above conversion

The data of ju88 in China uses the data of earlier models, so it is lower, but the author believes that even if later models are included, b25j still has an advantage in load.) The only advantage of ju88a series is that it can dive, which is not suitable for guided weapons

Not really

It is necessary. In terms of speed, the speed of b25j is similar to that of ju88a. In terms of engine, b25j uses a 1700 horsepower r2600 air-cooled engine, while ju88a uses a jumo211j liquid-cooled engine with about 1400 horsepower.

Engine, in terms of protection and maintainability, the b25j air-cooled engine has more advantages. (Even the do217 bomber with a relatively large internal oil only has 773 gallons of internal oil. It is still less than the b25, and it is also unable to

High angle dive.)
