Holland launched his first under-sea craft in 1875. Holland (an Irish immigrant) and Simon Lake. Similarly, there were submarine successes in the United States by rival inventors John P. Further French progress in submarines was marked by the four Sirène-class steam-driven undersea craft completed in 1900–01 and the Aigrette, completed in 1905, the first diesel-driven submarine of any navy. The Narval made a large number of successful dives. The ballast tanks were located between the double hulls, a concept still in use today. Launched in 1899, the Narval was a double-hulled craft, 111.5 feet long, propelled on the surface by a steam engine and by electric motors when submerged. A most successful French undersea craft of the period was the Narval, designed by Maxime Laubeuf, a marine engineer in the navy. The end of the 19th century was a period of intensive submarine development, and Zédé collaborated in a number of designs sponsored by the French navy. In France, Gustave Zédé launched the Gymnote in 1888 it, too, was propelled by an electric motor and was extremely maneuverable but tended to go out of control when it dived.
But the battery had to be recharged and overhauled at short intervals, and the craft was never able to travel more than 80 miles without a battery recharge. This Nautilus, propelled by two 50-horsepower electric motors operated from a 100-cell storage battery, achieved a surface speed of six knots (nautical miles per hour one knot equals 1.15 statute miles per hour or 1.85 kilometres per hour). The submarine Nautilus, built in 1886 by two Englishmen, was an all-electric craft. Development of the electric motor finally made electric propulsion practicable. In an effort to overcome the problems of propulsion, two French naval officers built the 146-foot submarine Le Plongeur in 1864, powered by an 80-horsepower compressed-air engine, but the craft quickly exhausted its air tanks whenever it got under way. Several nations built submarines to Nordenfelt’s design. His craft could be submerged by vertical propellers to a depth of 50 feet and was fitted with one of the first practical torpedo tubes. Similarly, the Swedish gun designer Torsten Nordenfelt constructed a steam-powered submarine driven by twin propellers. The fire had to be extinguished before the craft would submerge (or it would exhaust the air in the submarine), but enough steam remained in the boilers for traveling several miles underwater. Garrett, successfully operated a submarine with steam from a coal-fired boiler that featured a retractable smokestack.
