Pentagon can suck a square for all I care. There's a difference between American and Russian approaches, that is all.
These two examples demonstrating the American need for a new shiny thing at a loss of a working perfectly fine but old less-shiny thing.
Plus it demonstrates how corrupt the US Navy is.
You just don't understand the Russian approach, that is all. Russians build for ages, with modification/upgrades planned in the future. All so called old antique tech that you see on the outside - is modern on the inside. You are being fooled by the looks and of course projecting the American approach on Russia. The exceptionalism of Americans is just an opinion, mate.
Americans need to have 100% satisfaction for 1000% cost. Russians are content with 80% satisfaction for 10% the cost. Numbers are examples only. You never need 100% in real situations (because it's impossible to achieve in real situations, not talking about theoretical simulations), it's a waste to aim for it.
