The only inconvenience I see in that case is the secrets of submarines when they are being built. It won't be easy to follow SSK and SSN launches, what's more, how good they are. Especially for some of us with only shallow open-source knowledge. DDG, Frigates are easy to spot.We do. I suppose this wave of ship building is coming to an end and the next wave will be a wave of submarines lead by 039C.
