Sevastopol (Russia), July 26 (RIA Novosti) The Russian Navy is developing a concept of building a balanced nuclear missile force by 2050, the Russian Navy commander said Sunday.

'In our understanding, it is important to know exactly what the navy should be by the year 2050, proceeding from two things: it must be a balanced nuclear missile force and, secondly, it must comply with the state's national interests and economic possibilities,' Admiral Vladimir Vysotsky said on the occasion of Russia's Navy Day celebrated Sunday.

Vysotsky said the Russian Navy should develop harmoniously without any preference given to the construction of surface ships or submarines.

'We will be building combat systems in addition to warships. I call this the construction of the navy with open architecture, which will feature combat systems, complexes, ships, aircraft, anti-missile defence, outer space and the submarine environment,' he said.

Vysotsky said that failures with the tests of Russia's new Bulava sea-launched intercontinental ballistic missile manifested a crisis in the development of technologies in Russia.

The missile, which is being developed by the Moscow-based Institute of Thermal Technology (MITT), has had six failures in 11 tests, and the general director of the institute resigned last Tuesday over what is believed to be a serious setback in the development of Russia's nuclear deterrent.
