Mercy deployed in support of the nation's COVID-19 response efforts, and served as a referral hospital for non-COVID-19 patients admitted to shore-based hospitals. This allowed shore-based hospitals to focus their efforts on COVID-19 cases. One of the Department of Defense's missions is Defense Support of Civil Authorities. DoD is supporting the Federal Emergency Management Agency, the lead federal agency, as well as state, local and public health authorities in helping protect the health and safety of the American people.
