The 600-ship Navy was a strategic plan of the United States Navy during the 1980s to rebuild its fleet after cutbacks that followed the end of the Vietnam War. The plan, which originated with Republican leaders, was an important campaign plank of Ronald Reagan in the 1980 presidential election, who advocated a larger military and strategic confrontation with the Soviet Union. The number of ships peaked at 594 in 1987, before declining sharply after the end of the Cold War in 1989–1991. The program included: Recommissioning the s Keeping older ships in service longer A large new construction program Stepped up production of s The idea was supported by John F. Lehman, who became Reagan's Secretary of the Navy, and Caspar Weinberger, Reagan's Secretary of Defense. Background The idea behind the 600-ship Navy can be traced back to the Vietnam War. During the war, the armed services rapidly expanded to meet the demands placed on them. The Soviet Union, which had been supporting North Vietnam, began staging their naval vessels from former US ports in South Vietnam. Building on this gain, Soviet vessels began to sail in all seven seas with increased vigor and even ventured into the Gulf of Mexico. Soviet forces also stepped up infantry, armor and air force deployments in Eastern Europe. Reagan plan It was against this backdrop in 1980 that the United States began an election year. Ronald Reagan continued this in 1984, releasing a campaign commercial "Bear," which played on the use of the bear as a national symbol of Russia in order to promote higher vigilance and defense expenditures against the Soviet Union. The overseas strategic retaliation arm was strengthened and the development of new weaponry like the B-1B bomber, the Bradley fighting vehicle, and the Abrams tank was completed and they were put into production. Lehman attempted to "front-load" the program, by committing the Navy to the building program, but in the end the funds were not available and it fell short. Ships and weapons systems deployed during the plan The Navy saw the largest benefit of the rebuilding. Under the Reagan Administration, the first of the ballistic missile submarines were completed. This class was the largest submarine ever built in the US. The ship carried 24 Trident I nuclear-capable missiles, each one with a range. Construction of the Nimitz class of supercarriers and attack submarines was dramatically stepped up. The revolutionary
