Even 750 F35s is not enough to contain the J-20, so the US military has to build a sixth generation fighter as soon as possible at all costs

On January 5, 2022, the U.S. Department of Defense and Lockheed Martin issued the first monthly briefing of 2022:In 2021, the three final assembly lines in Fort Worth, Texas, Italy, and Nagoya, Japan, delivered a total of 142 F-35 fighter jets, three more than completed, so far the total production line has exceeded 750, 151-153 will be produced in 2022, it is expected that by August 2023, the total production of F35 will break the 1,000 mark.However, the total production of J-20 is less than 100 due to a series of reasons, such as immature production technology and failure to domesticate the engine. It can be said that F35 has established a large number of advantages, so can it use this advantage to suppress J-20 in air combat?At the beginning of 2022, the total number of F-35s has exceeded 750. Some people may say that air combat between the fifth generation of aircraft is difficult to happen because they cannot see each other, but that was before, with the continuous development of information technology, the original stealth effect has been greatly reduced.It is absolutely no problem to reliably determine the approximate coordinates of F35 through data fusion of the signals of sky wave over-the-horizon radar and ship-borne meter-wave radar (there are dozens of air-defense destroyers equipped with meter-wave radar in China) to realize relay detection.In addition, with more and more advanced reconnaissance tools such as satellites and drones, even the airfields where the F35 is deployed are under close surveillance, so its every move on the ground can be said to be no secret. Moreover, the RANGE of the F35 is much lower than that of the J-20.It is also unrealistic to cover your tracks with a roundabout or low-altitude penetration.As a result, the F35’s movements and patterns of activity can also be reliably estimated.This means that the J-20’s radar is sufficient to achieve beyond-line-of-sight lock on the F35 if it is effectively guided.Unfortunately, the F-35 is also a multi-role fighter focused primarily on ground attack. The difference between the F-35 and the J-20, which focuses on long-range air control, is obvious in three aspects: first, radar line-of-sight.Although F35 and the j20 EOTS (infrared tracking system), but unlike radar, infrared sensor, after all, can’t use 24 hours a day, and it has a big drawback is not precise distance measurement, only depending on the integration of laser range finder, but the transmission distance of laser in atmosphere is very limited, so the EOTS still is a kind of auxiliary sensors,To better obtain target information, but also rely on radar.The J-20 radar antenna is larger than the F22’s APG77, and can integrate at least 2,000 T/R units, with a maximum detection range of 400 km, while the F35’s AN/APG-81 fire control radar has only 1,200 T/R units, with a maximum detection range of only 250 km, facing stealth targets.Even if their radar ranges were reduced by a fifth, to 80km and 50km respectively, the J-20 would still have a line-of-sight advantage of more than 50%, which means it can detect, lock on and fire before the enemy.The radar detection range comparison between F22 and F35 is speed.The F-35 is far inferior to the J-20 in both charge speed and cruise speed, and speed plays a key role in air combat. The fast side can decide where the air combat takes place, its position relative to the enemy aircraft and when to exit the battle.The j-20 uses a canard delta coupling layout with a special emphasis on high speed performance, and its slender fuselage has less supersonic trim resistance and shock resistance.Thanks to this, even the J-20 with taihang’s improved engine can still achieve supersonic flight without afterburner. After replacing turbofan 15, it can achieve supersonic cruise at Mach 1.6-1.8, and the maximum sprint speed of J-20 is much more than Mach 2.The fuselage of the F35 is too large and bloated, which is far from the requirements of supersonic area ratio. The shock resistance is very high, and the trim resistance is not small due to the rear flat tail layout, which results in the maximum speed of the F35 is only Mach 1.6.As a result, if the F-35 wants to fly supersonic or do more maneuvering with an overload, the afterburner has to be turned on. In this case, the fuel consumption is very high, which means that against the J-20, the F-35 will run out of fuel and crash, even if it is not shot down.Three, the firing rate of combat missiles.There is a common belief that the probability of aerial combat is less with the 5th gen, but the reality is that the probability of getting caught in close combat between 5th gen aircraft is more, not less.The early warning aircraft and refueling aircraft with high value and obvious signal characteristics are the primary targets of the fifth-generation aircraft. Therefore, it is inevitable for the fifth-generation aircraft of both sides to fight around these key nodes, which determines that although the battlefield space is wide, the operational space for the fifth-generation aircraft to obtain the maximum combat effectiveness is not large.Moreover, at the relative speed of Mach 2.5 between the 5th generation aircraft, the transition from beyond visual range air combat to close combat takes only a few tens of seconds. Moreover, the situation of each other is more unclear to both sides, which determines that the 5th generation aircraft are more prone to dangerous close combat.Unfortunately, the F-35 does not have a combat pod, so it can only launch combat missiles from the belly bay with a drop ignition method, which is not only difficult to lock after launch, but also very limited to launch overload.On January 28 of this year, two American F-22s and two Norwegian F-35s engaged in simulated aerial combat.But the result was kept secret, which is telling, because whoever lost would have dealt a heavy blow to the American air force.It is true, however, that four F-22s beat f-35 and E/A-18G electronic fighters in the red Flag exercise.No wonder American experts believe that if the F35 were to compete with the J-20, the battle loss ratio would be 4 to 1 or 6 to 1, or even more exaggerated, which is enough to show that the F35 can hardly defeat the J-20 by sheer numbers.With the completion of the domestication of the engine and the maturity of the production process, the J-20 is also about to enter the state of mass production, which can be seen from guifei’s plan to contract produce the J-10C. This will allow Chengfei to concentrate its limited resources on the PRODUCTION of the J-20.The gap in the number of fifth-generation aircraft between China and the United States is expected to narrow quickly.Faced with this situation, the US military had only two options: mass produce the improved VERSION of the F22 or directly deploy the sixth generation aircraft.But to restart making production line need to face what kind of difficulties for the already existing big cafe, go here, need to stress is that today, making and its advanced age, has passed, invested enormous resources to production a fighter has been behind The Times, in the strategic planning is highly desirable.The only other option, then, was to deploy the SIXTH generation aircraft as soon as possible. Indications were that the American sixth generation aircraft was already in the test flight stage, which would have been rapid if the cold War pace had been followed, as the F-15 made its first flight in 1972 and was fitted in 1974 only 17 months later.But America is a different place, and it will take more than will to restore it.Similarly, the pace of development of the sixth generation of Chinese aircraft should also be accelerated in order to calmly cope with the next round of competition between China and the United States.Photos of the test flight of the American sixth generation aircraft
