Chapter 689: Advantages of Optoelectronic Systems
Iraq did not gain the right to control the electromagnetic system, Iraq only pulled the United States to the same level as itself, that is, they were all jammed and could not use radio waves!
It is not only communications that are being interfered with, but even the radar of fighter jets is seriously jammed.
Theoretically speaking, only the radar with a phased array system can prevent interference by pointing the electromagnetic signal in one direction and gathering the most energy, and at this time, the airborne phased array radar is still in the development stage, and the pulse Doppler radar of the flat slot antenna has also become blind.
In the entire Gulf region, only the radar of the Patriot missile is still holding on.
However, the radar of the Patriot missile has a detection range of only 100 kilometers, and it cannot conduct radio communication, let alone guide the fighters of the coalition forces to fight for air supremacy.
On this day, the battle started again!
After the sudden use of a large number of jammers, successfully jamming the electromagnetic signals of the coalition forces, and even the newly taken AWACS aircraft were jammed to the point that they could not be used, the Iraqi fighters carried out a brave take-off operation.
The powerful air power of the coalition forces comes to a large extent from the system, and the early warning aircraft monitors the entire operational airspace, directs the fighters to conduct operations through the data link, and holds the electromagnetic and information rights, and the backward countries are almost the end of being passively beaten.
But now, the situation has changed.
Even the radar of the best F-15 fighters has a search distance of no more than ten kilometers, which is enough to be seen with the naked eye, and it is completely a way of fighting air combat within visual range!
Those allied pilots, who were accustomed to the direction of AWACS aircraft and calmly detected the enemy from the onboard radar and carried out BVR (over-the-horizon) attacks, suddenly found that they had to use their eyes to find the possible location of enemy planes, just like their predecessors in World War II who flew P-51 Mustang fighters. Do close-quarters grappling.
A four-plane formation, flying in a clear sky, the tail engine spewed a blazing tail flame, and the top of the twin hanging tails was sprayed with the logo of the US Air Force.
It is clear that Iraq is emitting such strong electromagnetic interference. There must have been large-scale operations! Therefore, these four F-15E attack eagles have been replaced with air superiority payloads, and four AIM-120 active radar-guided air-to-air missiles are already the most powerful anti-air weapons of the US Air Force.
The advantage of active radar is that the carrier aircraft does not need to continue to use its own radar after launch, although it may need to continue to guide at the beginning, but to the back. You can slap your ass and leave, this missile has a huge advantage over the Sparrow.
In previous battles, relying on this air-to-air missile, the US Air Force was able to easily win an over-the-horizon air battle without getting caught up in a close-range fight with enemy aircraft.
But now, under strong electromagnetic interference, the radar of the carrier aircraft cannot intercept the target. Over-the-horizon air combat became delusional, and. As pilots, the most important thing to grasp is the air situation around them, and now, they are completely blinded.
Although the AIM-120 missile is mounted, it is not usable, so. It will mainly rely on four other AIM-9 Sidewinder combat missiles.
At this time, the four F-15 fighters in the formation were flying in the sky like this, and the sound of salad salad was heard in the headphones all the time. It was necessary to rely on the roar to be able to barely let the people in the formation hear, and at the same time, the pilots on the outside of the formation kept twisting their necks and observing the surrounding airspace.
At this time, they envied the Navy's F-14 Tomcat fighter, which has the AN/AL-1 tactical camera reconnaissance system, and the core of this system is a long-distance optical television, which can automatically search for and identify air targets within more than 90 kilometers of the aircraft in clear weather, and display them in the cockpit.
If there is such a system, then they can not be so tired, and can only rely on the naked eye to observe the surrounding airspace, and the lack of airspace perception is quite terrible for pilots.
Moreover, they also know that their weakness has just become the strength of the opponent, and at this time the coalition forces already know that Iraq is equipped with a certain number of MiG-29 and Su-27 fighters, which are all carrying optoelectronic systems, even if it is the OEPS29 optoelectronic system of the MiG-29 with slightly inferior performance, the detection distance is more than 20 kilometers! And the Su-27 optoelectronic system, in a clear sky, the distance to observe such a target as the F-15, is up to fifty kilometers!
Tollett's eyes looked at the airspace on the right, and as a wingman on the right side of the formation, he had to detect the threat on the right in time for the formation.
However, when the formation made a course adjustment, the area he needed to defend was just the direction from which the sun's rays came.
Even though wearing goggles, it is still too difficult to observe the airspace from the background of the sun's rays. After looking at it for a while, Tollett's eyes became a little uncomfortable, and he had to lift his goggles and rub them with his gloved hands.
The U.S. Air Force, when has it ever fought such a battle? They have long been accustomed to engaging the enemy under the command of AWACS aircraft, and now this way makes them very uncomfortable.
As he rubbed his eyes with his hands, Tollette suddenly felt as if he had found something, and he closed his goggles again, his breathing suddenly rapid.
In that direction of the sun, what is flying? Some sparkling highlights!
"Attention, there's a missile coming!" Tollette shouted loudly over the radio, and in the cacophony of interference, he didn't know if the rest of the formation had heard. He pressed the lever hard to the right and performed a maneuver with a large overload.
Damn, how did those missiles fly?
In the bulging spherical fairing, the 36T infrared seeker is working, this seeker technology is advanced, and there is no longer a need for tail chase attacks, but an infrared seeker that can carry out omnidirectional attacks! Behind the warhead, there are 4 trapezoidal stabilizing wings. In the middle, there are four large inverted trapezoidal wings forming the main control surface, and at the tail are four fixed double triangular tails.
This missile is the new generation of air-to-air missiles of the Soviet Union, the main force of over-the-horizon attacks R-27!
The semi-actively guided R-27 missile is a generation behind the AIM-120, and if the US fighter carrying the AIM-120 fights under the command of the early warning aircraft under normal circumstances, it will be enough to beat the Iraqi Air Force to the ground.
But now, without the command of the AWACS aircraft, the F-15 fleet of air supremacy is also scurrying like headless flies, while the MiG-29 and Su-27 fleets of Iraq, which have an optoelectronic detection system, have launched a hunt.
This time, it was a Su-27 fleet, and the fighter was piloted by a Polish pilot, Colonel Alex Sechiak, of course, who is just a mercenary now, leading his own four-plane formation, and after taking off, he discovered the formation of the US Air Force by relying on the optoelectronic system, so he took his own formation, went around to the direction of the sun, and then turned over and carried out a relaxed over-the-horizon attack.
Electromagnetic interference is quite violent, although the N001 radar, which uses a large number of electron tubes, has a stronger anti-jamming ability, and will not have a detection range of more than 15 kilometers, let alone provide an irradiation signal for medium-range missiles guided by semi-active radars.
So, this time in the air, they simply did not carry the R-27R with a semi-active seeker, but the R-27T with an infrared seeker!
Due to the advanced electronic system of the United States, infrared seeker has not been used at all in medium-range missiles, because this guidance method will greatly shorten the range!
The front end of the radar seeker missile is an aerodynamic tip with low air resistance, while the infrared seeker has a spherical glass cover at the very front, which is much larger and the range is greatly shortened.
For example, the effective range of the R-27T is only forty kilometers, which is an indicator of high altitude, and at low altitudes, this effective range will be greatly shortened to twenty kilometers!
In order to hunt successfully, under the command of Alex, the Su-27 fleet used the optoelectronic system to lock on to the other side at a distance of almost fifteen kilometers, provided the R-27 missile with launch elements, and then launched its own missile, and after the missile flew five kilometers by inertia, the infrared seeker in front successfully locked on to the target.
The proud air superiority of the United States, the heavy air superiority fighter F-15, was dealt a heavy blow on this day.
In the strong electromagnetic interference, the pilot of the long plane of the F-15 did not hear it and was still flying forward, while the wingmen behind realized something after seeing the sudden maneuver of Tollett on the right and performed a sideways maneuver.
In the face of incoming missiles, they can only rely on their own level of performance, high overload maneuvering, combined with platinum bars or decoys, to throw off the missiles.
It's a pity that they subconsciously think that the over-the-horizon missiles flying are all radar-guided models, so they cooperate with the release of metal berths, which have no effect on infrared missiles.
"Boom!" The R-27 missile approached its target, the proximity fuse detonated the 39-kilogram warhead, and the fragmented warhead flew in the air, which was a rain of death for the F-15!
The F-15 that was attacked instantly turned into a fireball in the air, and the pilot fell down with the fighter plane before he had time to pull the ejection handle.
The four-plane formation was killed, and the other two fighters, just escaped from death, and saw the four large fighters killed from the sunlight on the opposite side!
American pilots, accustomed to over-the-horizon attacks, had to engage in close-quarters combat with fierce Soviet pilots! The distance between the two sides was rapidly approaching, and Tollett's breathing was a little nervous, and he quickly switched his weapon system to the Sidewinder missile, ready to trap the other party into his own missile attack envelope, and then attack!
