Aegis Destroyers, SSBNs and amphibious assault vehicles
The Chinese navy has been investing in everything from a new fleet of hovercraft that will land troops ashore during amphibious assaults to the new Type 052D class guided-missile destroyers, equipped with Aegis-style phased-array radars designed to track missiles and aircraft. (This is in addition to the older Type 052C class equipped with similar systems.) The Chinese navy is also fielding a new generation of nuclear missile-carrying submarines, the Type 094, designed to fire the JL-21 nuclear-tipped ballistic missile. Beijing's navy is also beefing up its amphibious assault capabilities with the ZDB05 fighting vehicle. The ZDB05 -- think of it as a swimming armored personnel carrier with guns -- is capable of hitting 16 knots in the water and then using its 30mm cannon, 7.62mm machine gun, and antitank missiles to protect the five to seven infantrymen it can deliver to the beach. Could be useful if China wanted to stake a claim on some islands in the South China Sea.
