contracts with a number of foreign countries soon to upgrade the Su-27
fighter planes currently in service with their air forces, Sukhoi director
general Mikhail Pogosyan said at a news conference devoted to the 20th
anniversary of the maiden flight of the first Su-27 manufactured in series.
According to Pogosyan, the Su-27, the basic variant of the fourth-generation

obliged to modify and further upgrade it to generations known called
4+ and 4++ in which all design potentialities of the basic version have
been brought out.
