BREMERTON, Wash. (Aug. 21, 2015) Cmdr. Jeff Bierley, commanding officer of the fast-attack submarine USS Seawolf (SSN 21), from Birmingham, Alabama, kisses his wife after the boat returns home to Naval Base Kitsap-Bremerton, following a six-month deployment. Seawolf is the first of the Navy’s three Seawolf-class submarines, designed to be faster and quieter than its Los Angeles-class counterpart.
