But type 093b are in production 7 in two years. At this rate 4 per year while waiting for type 095 and 096 to come online. China can also build aip type 093c in other shipyards. The US doesn't have the same luxury. They are running at max capacity while china is just chilling.if china is not happy with type 093b they wouldn't build this many. The expansion at bohai shipyard clearly demonstrates PLAN intention for mass production.China is very close to the Usa, they are only lacking in a deadly stealth nuclear submarine, aircraft carriers, and navy aviation, I believe soon this will be solved, they have newer submarines on the way, aircraft carriers being build and j35s nearly ready. Frigates and destroyers are already battle ready.
