It takes Russia years to finish a frigate...some of the larger corvettes has taken over 10 years to get ready. To think that a new large nuclear cruiser or a heavy aircraft carrier could be built by the late 2020 is wishing alot.
No what Russia should be doing is to concentrate on building a Green-water navy with smaller frigates and corvettes and keep on building ssbn:s for its strategic value. SSN:s could just be replaced by SSK:s with cruise missiles. How many Kilos and Ladas can u get for a price of one Yasen? Im not saying that all Akulas and Sierras should be scrapped right away, but to keep spending huge amount of money on 2-4 new nuclear submarines makes no sense.
