Amid rising tensions between Russia and Western nations, the former country has started developing modern frigates.
It is said that these modern frigates are being designed to be able to carry and launch more cruise missiles.
The work is said to have begun in the Northern design bureau.
The frigates will be developed, as per sources, to be capable of carrying up to 48 Kalibr cruise missiles.
The frigates will have a displacement of up to 7,000 tonnes.
The vessels will also carry Zircon hypersonic cruise missiles.
