190604-N-AX577-0068 PEARL HARBOR (June 4, 2019) Electronics Technician (Radio) 3rd Class Ronald Champion, from Los Angeles, unfurls the union jack during morning colors aboard the Los Angeles-class attack submarine USS Chicago (SSN 721), June 4, 2019. Nearly all ships and craft throughout the U.S. Navy displayed the union jack in lieu of the First Navy Jack in commemoration of one of the greatest naval battles in history, the Battle of Midway, which began this day in 1942. The change re-establishes the custom in which the commissioned ship in active status having the longest total period of active status, other than USS Constitution, will display the First Navy Jack until decommissioned or transferred to inactive status. Home ported at Joint Base Pearl Harbor-Hickam, Chicago is the 34th Los Angels-class nuclear powered attack submarine and was commissioned on September 27, 1986.
