Korovin, an expert at the Center for Military and Political Studies of the Moscow State institute of International Relations (MGIMO), was referring to tactical weapons of a potential adversary.
Almaz-Antey has recently transferred a set of new Buk-M3s to the Russian Defense Ministry. But experts say that this system will have to be replaced in the next decade and a half.
Korovin told RBC news channel that the Buk-M3 is a "profound and qualitative upgrade" of a complex developed in the 1970s, but it could not be integrated into the emerging network-centric command systems responsible for Russia's air defense.
Military expert Victor Murakhovsky described the next generation system as "significantly more automated and robotic" compared to its predecessors. It will have an electronic warfare component in addition to its firepower potential, he added.
