Putin approves big revamp of Russia's navy

"It is impossible to carry out such work without a long-term vision of the scenarios for the development of the situation in the oceans, the evolution of challenges and threats, and, of course, without defining the goals and objectives facing the Russian Navy," Patrushev said.

Patrushev gave no further details about the strategy, though Russia has ramped up spending on defence and security to Cold War levels as a percentage of gross domestic product.
