Today marks the 82nd anniversary of the beginning of the Battle of Saipan. On this day in 1944, elements of the 2d Marine Division and 4th Marine Division, alongside @USArmy Soldiers of the U.S. Army's 27th Infantry Division, landed on the beaches of Saipan's southwest coast, initiating what would become a brutal, nearly four-week engagement. American forces fought determined Japanese defenders, an elaborate network of caves, and challenging mountainous terrain. Despite these obstacles, they pressed forward with remarkable resolve. After successfully establishing a beachhead, the campaign shifted to a grueling assault through "Death Valley" and a push to secure the heavily defended commanding heights of Mount Tapotchau, which was finally captured in late June. A key strategic victory was achieved on June 18, 1944, when American forces seized Aslito Airfield, securing a critical objective that would place the Japanese mainland in range of U.S. long-range B-29 bombers. For their extraordinary bravery during the battle, 4 Marines and 3 Soldiers were awarded the Medal of Honor. While the Battle of Saipan commenced 82 years ago, the valor displayed by the Marines, Sailors, and Soldiers there remains a cornerstone of our military's history. Their actions helped solidify the Corps’ reputation as a formidable fighting force, a legacy that continues to this day. ✍️ (U.S. Marine Corps Graphic by Lance Cpl.

⚓📰 #USNAVY UPDATE: USS Colorado Returns to Fleet from Maintenance Ahead of Schedule, Accelerating Pacific Readiness PEARL HARBOR, Hawaii— Virginia-class fast-attack submarine USS Colorado (SSN 788) completed a scheduled maintenance period at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF) 29 days ahead of schedule June 10, 2026. Effective and efficient maintenance keeps the U.S. Navy lethal and ready to defend the nation and maximizes the lifespan of its vessels. By returning Colorado to the fleet ahead of schedule, the shipyard and crew demonstrated exceptional professionalism and capability. Maintenance was completed early through close partnership between the shipyard and Colorado’s crew. Using the Navy’s world-class planning processes, the joint team executed a complex work package safely and efficiently. Operating seamlessly within the submarine's confined spaces, an integrated team of shipyard craftsmen, engineers, support staff, and crew members utilized decisive, deckplate-level problem solving to complete repairs. “Finishing ahead of schedule is not about rushing, it’s about hard work and persistence,” said U.S. Navy Capt. Ryan McCrillis, commander of PHNSY & IMF. “It’s producing first-time, high-quality work and attacking every roadblock with urgency. It’s a team effort, from the newest apprentice to senior shipyard leaders, the ship’s force, the project team, and support from the fleet and headquarters.”

One battle forever changed the course of history. 84 years ago, America turned the tide in the Pacific by dealing the Imperial Japanese Navy a stunning defeat at the Battle of Midway, sending the four fleet carriers of the Combined Fleet beneath the waves. Though three more years of grueling warfare lay ahead, through the courage and sacrifice of American Sailors, Marines, and aviators, the United States would never again surrender the strategic initiative.
