The liquidation of the Zhukov Air Defense Academy in Russia's Tver may result in billions of losses for the country. It transpired that the renowned educational institution would be closed by July 1, 2012. A source at the defense department of Algeria said in an interview with Pravda.Ru that Algeria, being one of the main partners of Russia in terms of defense cooperation, would have to look for other opportunities for training air defense personnel and for purchasing adequate military hardware. The source also said that Algeria would have to look for a replacement in case Russia fails to provide decent conditions for the educational process of the personnel of Algerian air defense. A replacement for that could be found in China, the source added. If Russia is no longer capable of giving modern and adequate education that meets modern-day challenges, Algeria will have to refuse from the Russian military hardware. If there is no personnel the hardware will turn into expensive, yet useless defense machines. The defense cooperation with a number of other countries that buy air defense systems from Russia may come to a standstill as well. It is worthy of note that the sales of Russian air defense systems account for not less than a third of the total volume of defense deals with other countries of the world. As a result, Russia may lose many billions of dollars. There are many foreign students at the Air Defense Academy in Tver. There are more than 300 of them from 21 countries - from Serbia to South Korea.
