USS Theodore Roosevelt Prepares To Head Back Out To Sea

Following a COVID-19 outbreak on an aircraft carrier, crew members were tested and treated in Guam. Despite 1000 crew members still testing positive, over 2000 sailors have returned to the ship. The ship is set to undergo training and recertification, while quarantined aircrew will remain in Guam. Captain Carlos Ardillo now leads the ship, and an investigation into the outbreak and the firing of former captain Brett Crozier is ongoing.
