Russia will improve its air and space defense systems to counter possible threats from other nations, the country's air force commander said Tuesday.

Other countries, particularly the United States, will acquire new weapons such as hypersonic vehicles by 2030, and therefore will be able to deliver coordinated high-precision strikes from air and space against any target on Russian territory, Col. Gen. Alexander Zelin told a news conference.

Russia needs to upgrade its weapons and systems in order to counter such a potential, Zelin said.

In line with the new concept, air-space defense brigades will be created within the Russian Air Force and will be equipped with advanced S-400 and S-500 air defense systems, he said.

"The S-500 system is being developed under an original design ... and will be capable of destroying hypersonic and ballistic targets," Zelin said.

The commander said plans to develop hypersonic aircraft have not yet progressed beyond the theoretical stage. Russia's fifth-generation fighter plane was expected to perform its first test flight this autumn, he said.
