The ship class is the John Lewis class “fleet oiler,” and USNS Harvey Milk will be T-AO-206, the second unit of the class.

In company with Milk and John Lewis, the admired civil rights leader, will be Supreme Court Chief Justice Earl Warren, who is credited with jump-starting the Supreme Court in a career of political activism; Robert F. Kennedy, JFK’s brother and attorney general, assassinated in 1968 during a presidential run; Lucy Stone, the first American woman to obtain a college degree, and an activist for abolition and women’s rights; and Sojourner Truth, the remarkable former slave who also became a fiery abolitionist and civil rights activist.
