NOVO-OGARYOVO (Moscow Region), February 26 (RIA Novosti) - The Military-Industrial Commission, which answers directly to the Russian president, will meet Tuesday to consider prospects for a fifth-generation air-defense system, a senior Russian government official said Monday.

"It will be a field session, which will be held at the Almaz Science and Production Association," said First Deputy Prime Minister Sergei Ivanov, who oversees the defense related sectors.

Ivanov said new S-400 missile systems were adopted for service in late 2006 and will be placed on alert duty later this year.

"It is a unique system that has no parallels [in the world]," he said.

He said priority should now be given to the development of fifth-generation air-defense systems, combining elements of air-, missile-, and space defense.
