Force units were also housed at this base. Among them were the 1370th Photomapping Group, and refueling and maintenance functions. In 1951, the U.S. Marine Corps established a logistics base on the eastern outskirts of Albany. During the 1950s and 1960s, so many white servicemen and associated workers arrived that the city briefly became majority white for the first time since 1870. In 1960, the population of Albany reached 50,000 people. During 1961–1962, African Americans in Albany played a prominent role in the Civil Rights Movement (see the Albany Movement). They led protests and non-violent demonstrations to end segregation of public facilities, gain the right to vote, and advance social justice. Assisted by activists from SCLC, CORE, SNCC, and the NAACP, African Americans and supporters took a stand to fight segregation through nonviolence. The city repealed its Jim Crow laws in 1963, but African Americans did not recover the ability to exercise their voting rights until Congress passed enforcement authority with the Voting Rights Act of 1965. In 1967, the Air Force closed all its operations at the base, which was transferred to the U.S. Navy and renamed Naval Air Station Albany. NAS Albany was used as the shore base of nearly all the Navy's RA-5C Vigilante twin-jet, carrier-based reconnaissance aircraft. In 1974, the base was closed and the property was returned to the city. In 1979, the Miller Brewing Company purchased part of the old naval base's property to build a new brewery. The decline in military bases and railroad restructuring nationwide both led to job losses in the Albany area. Much of the remaining white population moved to suburbs and newer housing out of the city, which became majority African American in the 1970s. Struggling with a poor economy, in 1988 Albany made national headlines as the "Murder Capital of America," with the highest murder rate per capita in the United States. Other cities have since taken that title. Some late twentieth-century floods have been extreme. In 1994, a severe flood was caused by rainfall from Tropical Storm Alberto; it killed 14 people and displaced 22,000. The state supported a $150 million renovation of the Albany State University campus to repair storm damage and complete upgrades. New housing was built on the south side of town to replace what had been destroyed. In 1998, the Flint River crested at above its bed and flooded parts of the city.
