By DANIEL BETANCOURT | STARS AND STRIPES Published: May 6, 2021 YOKOSUKA NAVAL BASE, Japan — The Navy is offering as many as three years’ early separation to sailors in some “overmanned” rates and career fields before the end of fiscal year 2021, according to a Navy administrative message released Tuesday. The service exceeded its retention goals in FY 2020 and announced a select list of ratings would qualify for early separation, according NAVADMIN messages in December and January. The list includes boatswain’s mate, culinary specialist and hospital corpsman. “While we have grown over the years, some enlisted ratings have become overmanned, creating imbalances in the Fleet,” the chief of Navy personnel, Vice Adm. John Nowell, wrote in December’s message.
