PACIFIC OCEAN (Nov. 10, 2021) An MV-22B Osprey assigned to Marine Medium Tiltrotor Squadron (VMM) 164, based at Marine Corps Air Station (MCAS) Camp Pendleton, Calif., conducts flight operations aboard the Military Sealift Command (MSC) hospital ship USNS Mercy (T-AH 19) during Mercy Exercise (MERCEX) 22-1, Nov. 10, 2021. MERCEX 22-1 is a three-week-long pierside and underway training evolution that highlights integration, training and camaraderie between MSC civilian mariners and MTF Sailors. USNS Mercy (T-AH 19) can steam to assist anywhere to provide relief as a symbol of Navy Medicine's abilities around the world, and must be in a five-day-activation status in order to support missions over the horizon, and be ready, reliable and resilient to support mission commanders.
