The appearance of active radar-guided missiles was like a cold snap sweeping through Long Yun's heart.

As if following his train of thought, the colonel, who stated the battle situation, changed his words and moved to this topic:

“…… Combined with the information collection of the intelligence department, the combat reports fed back by the combat units, and the analysis of the intercepted signals of the RWR system, it is certain that a considerable number of US Air Force fighters have begun to use the new air-to-air missile system; Such systems have long been in the sights of intelligence services, and the West sometimes calls them 'Slammer', and the official weapon designation has been confirmed as AIM-120.

As for the specifics of this missile, I would like to ask Comrade Ushakov from the 'pennant' to explain to you. ”

As far as the colonel's gaze grew, Andrei Ushakov straightened his back, raised his hand to cover his mouth and coughed lightly twice.

Sorting out the paper in his hand before speaking, and when he opened his laptop, he looked up at Long Yun across the table, the technical major general who participated in the development of the Soviet air-to-air missile was obviously a little embarrassed, and perhaps he was still ashamed of Victor's careful guidance before.

The Americans have already put the AIM-120 missile into real combat, but where is the R-77, which they are in charge of?

Although he thought that the overall layout of the R-77 and the circuit and control parts had completed internal tests, the main problem was still the core equipment of the missile -- the radar homing head, and Ushakov still felt that he could not escape the blame. As a scientific researcher who is always at the forefront of the development of missile weapons, he certainly knows very well what the seemingly insignificant difference between "semi-active radar-guided missiles" and "active radar-guided missiles" means to pilots who are fighting bloodily.

"Ladies and gentlemen, the details and parameters of the AIM-120 missile are explained in more detail in the materials distributed. We can only speculate on this kind of process until we get the sample. If I want to briefly explain the current problem, I intend to talk about the technical characteristics and combat modes of active radar missiles, which I hope will be helpful to you in your thinking.

Leaving aside trivial details that are not related to the topic, both 'active radar-guided missiles' and 'semi-active radar-guided missiles' are oriented by radar reflections from the target;

The seemingly simple change in the working mode is reflected in the combat strategy of the carrier aircraft: To sum up, in one sentence, after the missile is launched, the carrier aircraft of the semi-active missile needs to use radar to provide target irradiation until the end of the engagement process, while the carrier aircraft of the active missile can end the irradiation and turn around and detach after the missile enters the homing direction. It's called 'launch and forget'. Based on the analysis of the above facts, the US fighter using the AIM-120 missile can achieve a clear asymmetric advantage in the battle with our fighter using the R-27 series of missiles. ”

As Ushakov's words paused, there was a brief silence in the room.

Red Air Force personnel who participated in this meeting. Basically, they were gradually promoted from the front line of the army, and they were all well aware of Ushakov's analysis process and basically agreed with the conclusions reached. The pressure felt at this time is naturally conceivable.

Because a simple assumption can be understood. When other conditions such as altitude, speed, occupancy, and air situation warning are equal, the combat situation of a fighter using a semi-active bomb and a fighter using an active bomb is completely unequal: in the face of the threat of an active bomb, even if the former adopts a correct over-the-horizon combat strategy, it can only withstand a very unfavorable combat exchange ratio.

When the approaching belligerents attack each other, the missiles gradually approach the target, and they themselves are also threatened by the enemy's missiles. The carrier aircraft of the semi-active missile must make a difficult choice between "maintaining the target irradiation" and "vigorously maneuvering and evading", while the active missile carrier aircraft can maneuver without scruples or simply turn around and disengage. Moreover, compared with the semi-active bombs that need to be continuously irradiated by the carrier aircraft, the active missiles that do not rely much on the radar irradiation of the carrier aircraft have better multi-target attack capabilities, which deepens the asymmetric disadvantage of the semi-active missile carrier aircraft in a certain range.

After a long silence. Only one of those present spoke:

“…… So, against the AIM-120 missile, can it be countered by means of electronic countermeasures? ”

"Oh, that's ......"

Hearing such a question, Ushakov hesitated for a moment, and then slowly shook his head:

"According to our speculation, the self-homing head of this missile is very advanced, and it should use frequency hopping and digital pulse coding technology; The electronic countermeasure system capable of jamming such a homing head, frankly, at the moment we are completely powerless. -- Or, to put it a step back, even if it were possible to build an electronic countermeasure system that met the requirements, the size and power consumption would be so staggering that it would be impossible to install it on an airplane. ”

Hearing Ushakov's explanation, not only did the questioner's expression darken, but the entire conference room also fell into a new silence.

In this unbearable silence, Long Yun's thinking did not stagnate; Imagining the battle scene in the Caucasus sky in his mind, he quickly flipped through the pages behind the report, although the information fed back by the intelligence department was still somewhat general, but combined with the reaction of the combat troops and some clues, he still had a guess.

In this inexplicable parallel world, unlike in reality, the AMRAAM project developed under the auspices of Raytheon did not progress very quickly, or due to the easing of the confrontation between the East and the West, the early AIM-120A missile does not seem to have entered the actual equipment stage.

According to the reports sent back by the combat units and the analysis of the numbers, the missiles that are now equipped with a large number of US Air Force fighters and add great variables to the current war shape should be the improved AIM-120B. Compared with the earlier Type A, the AIM-120B not only has a slight increase in range, but also has a digital processor, programmable ROM and some electronic component upgrades, and the performance has been improved by a certain degree compared with the prototype.

AIM-120B......

Faced with this thorny problem, Long Yun frowned unconsciously.

Since he traveled to a parallel world and experienced this world war, Long Yun had the idea of giving birth to the R-77 active radar-guided missile very early, but because the Soviet Union objectively lagged behind the level of Western electronic technology, the "pennant" design bureau has not been able to come up with a usable active radar-guided missile until today.

In the face of the unprecedented threat of US active radar-guided missiles, the grim reality of the failure of missile weapons is in front of us. If we can't find a way to solve this problem, we can imagine that we will not have satisfactory results by relying only on strengthening tactics, technical training, and the pilots' will to fight, and Long Yun can be said to know this better than anyone present.
