SAN DIEGO (April 13, 2021) Retail Services Specialist 1st Class Julio Espejoperez, assigned to the embarked Medical Treatment Facility aboard the Military Sealift Command hospital ship USNS Mercy (T-AH 19), stands ready to raise the National Ensign as the ship departs Naval Air Station North Island (NASNI). Mercy is underway off the coast of southern California completing a Dynamic Interface exercise, where the ship�s aviation facilities will be evaluated for compatibility with the V-22 Osprey and MH-60 Sea Hawk, and establish launch and recovery windows in adverse weather conditions. Mercy recently returned to its homeport in San Diego from a regular overhaul in Portland, Ore., where improvements were made to its flight deck to support multiple aircraft platforms. Mercy must be in a five-day-activation status in order to project combat power over the horizon, and be ready, reliable and resilient to support mission commanders.(U.S. Navy photo by Mass Communication Specialist 3rd Class Luke Cunningham)
