Several tasks were considered for the vessel: destroying a bridge across Swift Creek, a tributary of the Appomattox River clearing away the obstructions in the James River at Fort Darling, which had prevented Union gunboats from steaming upstream to support General McClellan's drive up the peninsula toward Richmond and blowing up CSS Virginia II should that ironclad be completed on time and sent downstream to attack Union forces. A spring 1862 newspaper report called the vessel Alligator, in part because of its green color, a moniker which soon appeared in official correspondence. At Norfolk, the submarine was moored alongside the sidewheel steamer USS Satellite, which was to act as her tender during her service with the North Atlantic Blockading Squadron. The two vessels got underway on 19 June and proceeded down the Delaware River to the Delaware and Chesapeake Canal, through which they entered the Chesapeake Bay for the last leg of the voyage, reaching Hampton Roads on the 23rd. Next, the steam tug Fred Kopp was engaged to tow the submarine to Hampton Roads, Virginia. On 13 June, the Navy formally accepted the boat. Two weeks later, she was placed under command of a civilian, Mr. Soon after her launching, she was towed to the Philadelphia Navy Yard to be fitted out and manned. Samuel Eakins, first commander of Alligator Operational history Plan of his submarine, by Brutus de Villeroi, describing the oar arrangement. Nevertheless, the work proceeded so slowly that more than 180 days had elapsed when the novel craft finally was launched on. The Union Navy's agreement with the Philadelphia shipbuilder specified that the submarine was to be finished in not more than 40 days its keel was laid down almost immediately following the signing on 1 November 1861 of a contract for her construction. The Union Navy wanted such a vessel to counter the threat posed to its wooden-hulled blockaders by the former screw frigate Merrimack which, according to intelligence reports, the Norfolk Navy Yard was rebuilding as an ironclad ram for the Confederacy ( CSS Virginia). Divers could affix mines to a target, then return and detonate them by connecting the mine's insulated copper wire to a battery inside the vessel. The boat had a forward airlock, and was the first operational submarine with the capability for a diver to leave and return while both remained submerged. Air was supplied from the surface by two tubes with floats, connected to an air pump located inside the submarine it was the first operational submarine to have an air purifying system. On 3 July 1862, the Washington Navy Yard had the paddles replaced by a hand-cranked propeller, which improved its speed to about four knots. For propulsion, she was equipped with 16 hand-powered paddles protruding from the sides. "It was made of iron, with the upper part pierced for small circular plates of glass, for light, and in it were several water tight compartments". The boat was about 47 feet (14 m) long, with a beam of 4 feet 8 inches (1.42 m) and height of 5 feet 6 inches (1.68 m). In the autumn of 1861, the Union Navy asked the firm of Neafie & Levy to construct a small submersible ship designed by the French engineer Brutus de Villeroi, who also acted as a supervisor during the first phase of the construction (de Villeroi had designed and built submarines in France and one after immigrating to the United States).
