The Ohio-class ballistic missile submarine USS Nebraska (SSBN 739) transits the Hood Canal as it returns home Naval Base Kitsap-Bangor, Washington, following the boat's first strategic patrol since 2013.
Nebraska recently completed a 41-month engineered refueling overhaul, which will extend the life of the submarine for another 20 years. (U.S. Navy photo by Mass Communication Specialist 1st Class Amanda R. Gray) Original public domain image from Flickr
