During the parade on the Red Square on June 24th, the Russian Air Force displayed the most advanced fifth-generation fighter, the Su-57, on a large scale, earning a lot of attention. Next, Russia hopes to turn advanced weapons into "foreign exchange weapons." According to the Russian Red Star, in view of the fact that the Russian military will only purchase 76 Su-57s in the next eight years, Sukhoi has started the export business of the aircraft in order to keep the production line running, and has obtained a government license for this purpose. According to the predictions of the Russian media, India, Vietnam and Algeria are the priority sales targets.

  Have to go through confidential treatment

  The Russian army once emphasized that the Su-57 was a high-quality weapon made with "top secret technology", but now it is allowed to be exported, and various concerns about "leakage" have followed. In fact, Russia has extensive experience in handling export and confidential relations. Like other military technical equipment for export, the Sukhoi Su-57E fighter aircraft prepared by Sukhoi has a special "technical profile", that is, its performance indicators are generally at least one order of magnitude worse than that of its own military-used Su-57. It is reported that the most important confidential components of Su-57E are equipped with anti-prying protection devices, and these components are usually maintained by Russian experts.

  Similar to other export-oriented weapons, the biggest difference between the Su-57E and its own military is that it has a different "inner core", which is embedded with an enemy and enemy identification system, and usually does not appear to "fight yourself". In addition, the procurement target usually maintains long-term friendly relations with Russia, or does not have ally relations with the United States, and generally does not have to worry about the issue of fighters being handed over to the United States. It is worth mentioning that in addition to making profits by exporting aircraft, Russia can also firmly lock in the revenue of spare parts, repairs and consumables through contracts that last for several years, which not only provides sufficient funds for the rolling development of its domestic military industry enterprises, but also Squeeze the arms export channels and market share of the United States, Britain, France and other countries.

  In recent years, Russia has learned from the experience of arms exports after the disintegration of the Soviet Union. When signing contracts for the export of advanced weapons such as S-400 surface-to-air missiles and Su-35 fighter jets, it has signed intellectual property protection clauses with the purchaser to limit the other party’s impulse to copy. The Russian military complex said that fighter jets are not just a problem of wings and engines, but also include electronic equipment and even necessary metal alloys. These are not mastered by most countries. Even if they want to clone, I am afraid that they are still overwhelmed.

  Is this plane so godlike

  The Su-57 was developed to replace the Su-27 heavy fighter aircraft in active service of the Russian Air and Space Army. It first flew in January 2010 and was finalized in 2017. It uses so-called "stealth" technology and can compete with any type of enemy fighter. In February 2018, four Su-57s flew to Syria, launched cruise missiles to attack terrorists, and gained practical combat experience.

  However, on December 24 last year, a Su-57 crashed near the Far East Zemji Airport. This was the third accident during the test of the Su-57 fighter. The first two were: in August 2011, a Su-57 participated in the Moscow Air Show. When the ground accelerated, the deceleration parachute suddenly popped up, causing the aircraft to fail to take off; in June 2014, a Su-57 landed at the same airport The rear air intake caught fire. These accidents have caused people to question their reliability.

  In addition, according to the standards of the fifth-generation machine, Su-57 has been criticized for two major indicators. One is stealth technology, which is not good at reducing the radar reflection cross section (RCS) on the front of the fighter. Its intake port communicates with the engine. The engine fan blades are not covered. The high-speed blades form a strong radar reflection source, which is difficult to achieve effective. Stealth in the first hemisphere, and in the air combat, when the aircraft of both sides approached, the nose is aligned with the nose, and the frontal stealth ability is poor, it is difficult to launch an attack in the air. The second is the engine. So far, Su-57 has cited only the "fourth and a half" level of the 117S turbofan engine. If compared with the power of the US F-22 fighter, it is actually outdated, although Russia has announced that it is truly -57 matching fifth-generation engine-"30 products" has been finalized, but the actual installation is still far away.
