Tug boats push the USS Kitty Hawk (CV 63) towards Singapore's new deep-draft vessel pier at Changi Naval Base on March 22, 2001. The Kitty Hawk is the first U.S. aircraft carrier to moor at the pier which is one of the few piers in the Pacific that is large enough to berth a carrier and only one of two located in Southeast Asia. The aircraft carrier is in Singapore for a scheduled port visit during a routine deployment.
