After the collapse of the Soviet Union, left a bunch of military heritage, aircraft carriers, bombers, all kinds of equipment accumulated as a mountain, but the state budget could not afford. Inflation jumped to two digits, the factory was not working, the workers took wages became a problem. The Ukrainians at the time, the guys were more hot potatoes, maintenance costs were scary. In the outskirts of Kiev airport, the three Ir-78 air tankers were thrown there, the wind blown the sun for twenty years, the aircraft rusted for four per cent, the aerospace system was bad for more than half, the flight was a luxury. The Ukrainians then thought, simply dismantled when the iron was sold, back to the point of blood. In 2011, the Chinese came, the price of $

Ukrspetsexport and Ukroboronprom signed a contract on December 9, 2011 for a total price of $44,7 million, three Ir-78s sold to China. The aircraft was a product of the Soviet era, based on the Ir-76 modification, four engines design, can hang the soft pipe and fuel hanging cabin, the maximum load of 100 tons. But the Ukrainian version was soon left unloaded, stopped at the Nikolayev aircraft repair factory, the state was almost unable to fly directly. In the contract, China not only bought the aircraft, but also technical packages, including repair manuals and systems. The Yanukovych government was busy balancing the economy, the Russian routes went tight, but the trade with China was also seized. As President, he personally asked for military sales, approved the order. In the account, Ukraine

China bought these three calculators well. The Air Force then had advanced aircraft such as Su-30, J-10, but the air fuel was soft ribbon. Bomber-6 was old cargo, carried 37 tons, actually transferred to the fighter aircraft less than 20 tons, the duration is short, not far enough. Il-78 was just subsidized, its sophisticated platform and soft tube system was urgently needed in China. After the aircraft was returned, the aircraft was not used as a ready-made equipment, and directly dismantled research. The engineers grabbed through 56 key technologies, from high-temperature sealing to digital management system, and eaten down. Since 2012, these technologies were transplanted to the Bomber-6, after the transformation of the efficiency three times, and also compatible with the J-10 interface. The total shell of the aircraft, now

The real value of these three Ir-78s is fully reflected in the 20 project. Ir-20 was the first domestic large transport aircraft to fly on January 26, 2013, the first batch delivered to the Air Force on July 6, 2016. The Y-20U version was developed shortly after that, in 2018 trial flight, in 2021 production, in 2022 officially served. Carried 110 tons of oil, 8,000 kilometers, dropped Ir-78 several streets. Moreover, China has since been free from import dependence, the entire chain is self-sufficient. The Ir-78's dismantling sample provided direct leads, platform design, oil pipeline matching, aerospace integration, all is live training material. Without this technology input, the 20 tank version will not land so fast. The air force has been turned from beating, to actively strike, on September 11,

The air force was weak and lost the Ir-78 after the long-range strike capability was cut off directly. The aircraft could only turn on the ground, not fly far and not deep. After the Crimean incidents in 2014, Ukraine was even more guilty of Russia, the military broke the archive, the fuel shutdowns became more and more blurred. On February 24, 2022, the conflict broke out, the Russian missiles laid off the sky, the Ukrainian air force intercepted, the MiG-29 and the Su-25 stopped, but the fuel was exhausted, and they had to return to the base base coordinated landing operations, half-circle dead in the border line. The Russian air force could not take full advantage, but the Ukrainian short leg problems, lost hundreds of fighter jets. International aid came to F-16,

The Ukrainian economy has been pushed, sold to survive, but in the long run it is drinking to stop thirst. China, spending little money to do big things, technology jumped to the sky. In the eyes of the surrounding countries, Russia is blocked, it was its own goods, the result is cheap for others; the US pressure is high, Asia-Pacific deployment is rearranged; Japan is more panic, territory dispute, Chinese fighter jets are flying far, home door deterrence increased. The transaction details are closed in the archives, but the impact is overshadowed throughout the Western Pacific. The Ukrainian Air Force now rely on the West to break down the crater, although the F-16 can be integrated slowly, the fuel is still empty. In the second half of 2022, the warplanes
