After my country’s Type 003 aircraft carrier "Fujian" was launched, the accompanying J-35 stealth carrier-based aircraft also accelerated its test flight progress, and test flight pictures frequently appeared on the Internet. Just recently, the J-35 fighter jet carried a Longbot lens for another test flight. This indicates that the test flight work has entered the final sprint stage, triggering heated discussions among netizens.
The J-35 frequently test flies
As can be seen from the latest pictures, the J-35 test aircraft has extended its landing gear and is about to land on the airport runway. An obvious bulge appears under the smooth fuselage. The sharp-eyed Netizens recognized this object at a glance as a Longbot lens. Judging from its appearance, this Longbot lens is the same one carried by the J-20 fighter jet. From the later stage of the test flight, the J-20 fighter began to mount this Longbot lens under the belly. Since then, in all public videos and pictures, the J-20 will almost without exception mount this device. .
J-20 fighter jets also often carry a Longbo lens
The Longbo lens is an ellipsoidal multi-faceted refractive lens. It can focus the incident electromagnetic waves of a specific wavelength, and then reflect them back along the original ray direction, which greatly increases the radiation intensity. The role of large reflected wave . In the military field, the Lomberg lens reflector is one of the important false targets and radar decoys in electronic countermeasures. It plays a strong interference role. The Lomberg lens reflector with a diameter of 0.3 m can simulate an Radar echo of heavy bomber . In the flight training of stealth fighters, Longberg lens reflectors are generally carried to increase the radar reflection area, which can facilitate identification by ground radar stations, avoid flight risks caused by too small radar reflection waves, and also hide the true identity of the fighter aircraft. The radar signal prevents the enemy from obtaining absolute information, so stealth fighters need to carry this equipment during non-war times.

Previously, the J-35 fighter jet did not carry the Longbot lens when it was approved for green "skin" test flights. After changing the gray paint, the J-35 began to carry the Longbot lens for test flights. It shows that the current J-35 fighter jet has been sprayed with the latest stealth coating, and its stealth performance has been greatly optimized. The predecessor of the J-35 fighter is the FC-31 stealth fighter developed by Shenyang itself. This fighter has an advanced stealth shape and DSI air inlet , and has stealth performance that is not inferior to the J-20 fighter. After using the latest wave-absorbing coating, the stealth capability of the J-35 fighter has been raised to a new level. Its radar reflection wave is two orders of magnitude lower than that of traditional non-stealth fighters. Therefore, in order to allow the ground tower to grasp it at any time The flight status of the J-35 fighter requires the installation of a set of Longberg lens reflectors under its belly. Of course, the J-35 fighter can be replaced with a retractable Longbot lens in the later stage. At ordinary times, the lens extends out of the aircraft to hide the fighter's true stealth data. In wartime, it can be quickly recovered into the aircraft to fully utilize the fighter's stealth performance. One-click switching between stealth and non-stealth.
The J-35 fighter jet during the test flight was not sprayed with a stealth coating at this time.
The FC-31 fighter jet has excellent stealth performance.
Judging from the test flight process of the J-20 fighter jet, the J-20 fighter jet entered the small batch production stage in 2016. It was equipped with a Longbot lens reflector. From 2011 to 2015, there were basically no J-20 fighters equipped with lenses. To a certain extent, the installation of Longbot lenses on the J-35 stealth fighter indicates that the test flight has entered the later stage. . Although the J-35 fighter will only make its first flight in October 2021, its first flight can be traced back to October 2012. Shen Fei has developed 3 versions of the FC-31 fighter before the final version. It can be said that before the emergence of the J-35, Shenyang Aircraft Industry has accumulated a large amount of test flight data. The test flight procedures related to the J-35 can completely simplify the process and greatly shorten the test flight cycle.

The J-35 fighter will gradually install the active phased array radar (AESA), the airborne infrared tracking and search system (IRST), and the optoelectronic distributed aperture system (EODAS ) and other airborne electronic equipment have entered the avionics system testing stage. Since the avionics system used by the J-35 fighter is basically the same as that of the J-20 fighter and is technically very mature, the avionics system testing of the J-35 fighter will not take a long time. Judging from the current progress, the J-35 fighter is likely to enter the trial batch production stage at the end of this year or early next year. Only by racing against time can it be tested on the "Fujian" aircraft carrier before it is put into service.
The J-35 fighter jet in test flight
After completing the Shenfei test flight project, the J-35 fighter jet still needs to fly to the flight test institute for finalization test flight. After the completion of the finalization test flight, it will need to conduct a large number of ejection tests on land to adapt to Regarding the aircraft carrier operating environment, according to expert speculation, the "Fujian" aircraft carrier may enter service around 2025, so there is not much time left for the J-35 fighter jets to conduct test flights and tests.
As the core force of my country's future aircraft carrier-based aircraft , the J-35 stealth carrier-based aircraft bears the important task of suppressing the American F-35C carrier-based aircraft, and its role is self-evident. After the J-35 fighter jets board the "Fujian" aircraft carrier, the F-35C stealth carrier-based aircraft that the U.S. Navy is proud of will completely lose its combat advantage, and the gap between Chinese and American aircraft carriers will be significantly narrowed.
