The Navy has completed a majority of its damage assessment of USS Port Royal (CG 73), which ran aground a half-mile off Honolulu Airport's Reef Runway Feb. The propeller blades, sonar dome and underwater hull were among items damaged on the 567 ft guided-missile cruiser. Critical systems -- such as the vertical launch cell hatches and other weapons systems, the AEGIS radar system, ballistic missile defense capability, surface-search radar, anchors, antennae and gas-turbine engines -- were not damaged.
