The USS Holland Submarine - John Holland
In 1862, the United States Federal navy tested a prototype submarine called Alligator </od/weirdmuseums/ig/Submarine-Photo-Gallery/The-Alligator-Submarine.htm>. The Alligator submarine was intended for operations in the
In 1872, the Navy unsuccessfully tested Intelligent Whale </od/weirdmuseums/ig/Submarine-Photo-Gallery/Intelligent-Whale-Submarine.htm>, another hand crank-powered submarine that failed. After the Intelligent Whale's failure as a submarine, inventors realized that until a propulsion method better than manpower could be developed for underwater use, submarines were not going to be worth the effort.
John Holland
By the last decade of the nineteenth century steam propulsion had replaced sail power in the
Navy. In 1896, the Navy insisted that submarine designer John Holland build his first contract submarine named the Plunger, with a steam engine for surface propulsion.
John Holland, an Irish-American school teacher and inventor, objected to steam power in submarines. Nonetheless John Holland built the Plunger with three steam engines to meet the Navy's prescribed surface speed.
The Plunger
During dock trials of the Plunger submarine, the temperature in the fire room reached 1370F with the power plant at 2/3 rated output. Similarly, during Plunger's sea trials a crewmember reported, "When we tried to submerge, it was so hot no one could live in her." Today, the nuclear reactor has eliminated this drawback to a heat source and submarines are driven by steam. But, before the advent of nuclear power, the internal combustion engine was the submarine's first viable source of power.
Internal Combustion Engine
The internal combustion engine </library/inventors/blinternalcombustion.htm> offered speed and comparative endurance on the surface, but its deadly carbon monoxide exhaust fumes and high oxygen consumption were obstacles to life beneath the surface. By 1900, submarine designers had solved this problem with the storage battery and electric motors. John Holland was the first to conceive of employing electric motors and the internal combustion engine to power a submarine.

John Holland built six submarines, including one under government contract, before the Navy would accept one of his underwater boats. The Navy also considered, but decided not to accept,
USS Holland
In 1900, John Holland sold the US Navy its first viable submarine, USS Holland (SS-1) </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Holland--SS-1-.htm>. This submarine was originally named Holland VI and was not developed under Navy contract. Holland VI was designed and built by its namesake using his own funds. USS Holland had the "amazing speed" of seven knots surfaced, made possible by her 45-horsepower internal combustion engine. She also had an endurance of several hours submerged when running on rechargeable storage batteries.
The USS Holland was armed a single torpedo tube and a pneumatic dynamite gun that fired through an opening in the bow. The

John Holland's boats were given neutral buoyancy by admitting water to balance the weight of the boat with the weight of water it displaced. With diving planes and a constant source of power, Johm Holland's boat could dive and surface on diagonal lines.
John Holland Submarine Diving
John Holland's principle, with some alternatives for fast diving and surfacing, is still used by modern submarines.
For all its innovations, the USS Holland </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Holland--SS-1-.htm> had at least one major flaw; lack of vision when submerged.
The submarine had to broach the surface so the crew could look out through windows in the conning tower. Broaching deprived the

Lack of vision when submerged was eventually corrected when
Sir Howard Grubb, designer of astronomical instruments, developed the modern periscope that was first used in Holland-designed British Royal Navy submarines. For more than 50 years, the periscope was the submarine's only visual aid until underwater television was installed aboard the nuclear powered submarine USS Nautilus </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Nautilus.htm>.
