U.S. Navy ships and craft will return to flying the union jack effective June 4, 2019. The date for reintroduction of the union jack commemorates the greatest naval battle in history: the Battle of Midway, which began June 4, 1942.
“Make no mistake: we have entered a new era of competition. We must recommit to the core attributes that made us successful at Midway: integrity, accountability, initiative and toughness,” said Chief of Naval Operations Adm. John Richardson. “For more than 240 years, the union jack, flying proudly from jackstaffs aboard U.S. Navy warships, has symbolized these strengths.”
