Transfer to Pacific Fleet . In the 1990s , with the end of the Cold War in 1991 and the subsequent reorganization of U . S . military forces , a U . S . nuclear policy review recommended that the U . S . Navy reduce its inventory of " Ohio " - class fleet ballistic missile submarines from 18 to 14 by 2005 . An original plan to meet this goal by retiring the four oldest " Ohio " - class submarines , , , and was abandoned . Instead , those four were converted into cruise missile submarine s ( SSGNs ) . The conversions reduced the size of the Trident - equipped ballistic missile submarine fleet to 14 units . In order to balance the remaining Trident - equipped fleet between the United States Atlantic Fleet and United States Pacific Fleet , five ballistic - missile - equipped " Ohio " - class submarines relocated from the Atlantic Fleet " Ohio " - class submarine base at Kings Bay to the Pacific Fleet " Ohio " - class submarine base at Naval Base Kitsap at Bangor , Washington . Between 2002 and 2005 , , , , , and " Louisiana " relocated from Kings Bay to Naval Base Kitsap .
