A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.
A gyroscope is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum.
Jean Bernard Léon Foucault was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of Earth's rotation. He also made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
Radio control is the use of control signals transmitted by radio to remotely control a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of model vehicles from a hand-held radio transmitter. Industrial, military, and scientific research organizations make use of radio-controlled vehicles as well. A rapidly growing application is control of unmanned aerial vehicles for both civilian and military uses, although these have more sophisticated control systems than traditional applications.
Elmer Ambrose Sperry Sr. was an American inventor and entrepreneur, most famous for construction, two years after Hermann Anschütz-Kaempfe, of the gyrocompass and as founder of the Sperry Gyroscope Company. He was known as the "father of modern navigation technology".
The Type 91 was an aerial torpedo of the Imperial Japanese Navy. It was in service from 1931 to 1945. It was used in naval battles in World War II and was specially developed for attacks on ships in shallow harbours.
Robert Whitehead was an English engineer who was most famous for developing the first effective self-propelled naval torpedo.
Giovanni (Ivan) Biagio Luppis Freiherr von Rammer, sometimes also known by the Croatian name of Vukić, was an officer of the Austro-Hungarian Navy who headed a commission to develop the first prototypes of the self-propelled torpedo.
The Howell Automobile Torpedo was the first self-propelled torpedo produced in quantity by the United States Navy, which referred to it as the Howell Mark I torpedo. It was conceived by Lieutenant Commander John A. Howell, United States Navy, in 1870, using a 60 kg (130 lb) flywheel spun at a very high speed to store energy and drive propellers.
The Whitehead torpedo was the first self-propelled or "locomotive" torpedo ever developed. It was perfected in 1866 by Robert Whitehead from a rough design conceived by Giovanni Luppis of the Austro-Hungarian Navy in Fiume. It was driven by a three-cylinder compressed-air engine invented, designed, and made by Peter Brotherhood. Many naval services procured the Whitehead torpedo during the 1870s, including the US Navy. This early torpedo proved itself in combat during the Russo-Turkish War when, on 16 January 1878, the Ottoman ship Intibah was sunk by Russian torpedo boats carrying Whiteheads, though this story has been disputed in one book.
Frank McDowell Leavitt (1856–1928) was an American engineer and inventor. Leavitt devised one of the earliest machines for manufacturing tin cans and later invented the Bliss-Leavitt torpedo, the chief torpedo used by United States Navy in World War I. Leavitt was part of an emerging cadre of American engineers whose design feats were putting United States manufacturing might on the map at the dawn of the twentieth century.
The Bliss-Leavitt torpedo was a torpedo designed by Frank McDowell Leavitt and manufactured by the E. W. Bliss Company of Brooklyn, New York. It was put into service by the United States Navy in 1904 and variants of the design would remain in its inventory until the end of World War II.
The Schwartzkopff torpedo was a torpedo manufactured in the late 19th century by the German firm Eisengießerei und Maschinen-Fabrik von L. Schwartzkopff, later known as Berliner Maschinenbau, based on the Whitehead design. Unlike the Whitehead torpedo, which was manufactured out of steel, the Schwartzkopff was made out of bronze, enhancing corrosion resistance.
The Whitehead Mark 1 torpedo was the first Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. The US Navy made an initial acquisition of 100 Mark 1s, which, by the time they entered American service, were faster, had longer range and carried a larger warhead than Robert Whitehead's earlier models.
The Whitehead Mark 1B torpedo, designated as a Torpedo Type B, was a variant of the Whitehead Mark 1 torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. The primary differences between the Mark 1 and the Mark 1B were that the Mark 1B was longer, carried a heavier guncotton charge in the warhead and included an improved guidance system.
The Whitehead Mark 2 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. It was identical to the Whitehead Mark 1 torpedo, except for some mechanical details.
The Whitehead Mark 2C torpedo, also designated Torpedo Type C was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. It was probably based on the Whitehead Mark 1B, rather than a modification of the Whitehead Mark 2.
The Whitehead Mark 3 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892.
John McFarlane Gray, also known as J. Macfarlane Gray, was a Scottish engineer who invented a portable steam riveting machine and a steam steering mechanism for Isambard Kingdom Brunel's famous SS Great Eastern.
Benjamin Franklin Miessner was an American radio engineer and inventor. He is most known for his electronic organ, electronic piano, and other musical instruments. He was the inventor of the Cat's whisker detector.
