The USNS Geiger (T-AP-197), initially laid down as President Adams on August 1, 1949, was a notable transport vessel constructed by the New York Shipbuilding Corporation in Camden, New Jersey. Launched on October 9, 1950, she was sponsored by Mrs. Edward J. Hart and was renamed Geiger on January 2, 1951, during her conversion for Military Sea Transportation Service (MSTS) operations. The vessel was acquired by the Navy on September 13, 1952, and placed into service the same day. Designed as a troop transport, the Geiger played an active role during the Korean War and in subsequent peacekeeping missions worldwide. Operating primarily out of New York, she made numerous transatlantic crossings, delivering troops to European bases and returning military personnel and refugees to the United States. Her service was characterized by versatility and responsiveness, including deployments supporting the 6th Fleet in the Middle East, notably during the 1957 Syrian crisis and the 1958 Lebanon intervention, where she transported troops to counter pro-Soviet influences. Between 1959 and 1965, Geiger’s operations extended across Europe, North Africa, the Caribbean, and the Middle East. After the Cuban Missile Crisis, she facilitated troop rotations to Guantanamo Bay, Cuba. She also participated in Operation Steel Pike I in 1964, the largest peacetime amphibious exercise in the Atlantic, supporting the movement of combat-ready troops to Spain and contributing to a major American military landing operation. In the Vietnam War era, Geiger was deployed to Southeast Asia in 1965, arriving at Qui Nhon, South Vietnam, to support military buildup efforts. She transported troops from South Korea to Vietnam and rotated personnel between Vietnam and South Korea, showcasing her vital role in Southeast Asian operations. After returning to the U.S. in early 1966, she resumed transatlantic service before heading back to the Far East to continue troop transport duties. In 1979, the vessel was reassigned as the United States Training Ship (USTS) Bay State IV for the Massachusetts Maritime Academy. However, her service ended following a significant engine room fire in December 1981, which led to her being declared a constructive loss and returned to the Maritime Administration for disposition. The Geiger’s extensive service record highlights her significance in U.S. military and maritime history as a versatile troop transport during pivotal Cold War conflicts.
