170928-N-KC128-0135 PEARL HARBOR, Hawaii (Sept. 28, 2017) A Sailor assigned to the Los Angeles-class attack submarine USS Chicago (SSN 721) greets his loved one after the boat's arrival at its homeport of Joint Base Pearl Harbor-Hickam after completing a change of homeport from Naval Base Guam. Chicago's ability to support a multitude of missions, including anti-submarine warfare, anti-surface ship warfare, strike warfare, surveillance and reconnaissance has made it one of the most capable submarines in the world.
