Chinese Renhai Class Destroyer One Third the Cost of Australia's Hobart Class Air Warfare Destroyer and Has About Twice the Firepower
I'm no expert on matters nautical, nor matters martial or military. However I decided to check out the specifications of the Chinese Renhai class missile destroyer which was in international waters off Australia's East coast this week.
It's a monster. It has two banks of universal vertical launch system - or missile tubes - one that accomodates 64 missiles and the other which houses 48. It has 16 more 'missile tubes' than the 64 cell + 32 cell USA Arleigh Burke class missile destroyer.
