In May 2009, Richard E. Byrd was identified to conduct Pacific Partnership 2009 as a last minute replacement for the USS Dubuque (LPD-8), which was sidelined due to an outbreak of H1N1 virus. Pacific Partnership 2009 visited American Samoa, Tonga, New Caledonia, Kiribati (Tarawa), and the Marshall Islands from June to September. In the few weeks after being selected, the ship was outfitted with a quick-designed Reverse Osmosis Unit to make sufficient clean water while loitering in the remote waters and additional logistical items were brought aboard.
