When Tillman entered the Senate in 1895, he was opposed to expansion of the United States Navy, fearing the expenditure would cause the issuance of bonds by the president, which he felt would only enrich the wealthy. Tillman sat on the Senate Committee on Naval Affairs, and soon came to understand that South Carolina could benefit from naval appropriations steered towards her. A flow of federal funds to his home state resulted, beginning in 1900, followed by the establishment, in 1909, of the Charleston Naval Shipyard. Once Democrats took control of the Senate for the first time in Tillman's tenure, in 1913, he became chairman of the committee and allied with others from the southeast (such as Navy Secretary Josephus Daniels, a North Carolinian) to see that the bulk of naval appropriations would be spent there. In 1912 Tillman requested the US Navy determine the maximum size of battleship that could be produced. Over the next four years the Navy developed a series of designs, called the Tillman Battleship or Maximum battleship, that were significantly larger and more powerful than any battleship in service in the world. The Navy submitted the Tillman IV-2 design to Congress, but the US entry into World War I and the Washington Naval Treaty afterward put an end to such fantastic designs.
