In 1999, Buffalo was modified to carry a Dry Deck Shelter (DDS). In 2002, the Buffalo entered drydock in Pearl Harbor, Hawaii and became the first ship to undergo nuclear refueling in Hawaii. In late November 2005, the DDS was used to launch an underwater glider capable of gathering and storing information to be later transmitted by means of a built-in satellite phone. On 10 June 2008, Buffalo visited Olongapo City in the Philippines, allowing Filipino children to tour her.[1]
