Here at Weaponsman, we’ve discussed naval torpedoes before. We’ve done it in the light of early American torpedoes that have been recovered from the bottom of the sea, or otherwise rediscovered, and displayed in museums or otherwise studied. But the very first torpedo, at least the first successful one, came from the forgotten Navy of the Habsburg Empire, by way of an English inventor and entrepreneur.
Fortunately, there is a place where this early history is not only not forgotten, but preserved and memorialized, and it is present on the web at Torpedo of Rijeka, our Wednesday Weapons Website of the Week this week. It’s a website founded by enthusiasts of the first naval torpedo, and the first naval torpedo factory — in their Adriatic hometown.
When Farragut said, “Damn the torpedoes,” in the Civil War, the “torpedoes” that he referred to were what we think of today as naval mines. They were tethered to the bottom or shore, and meant to inhibit naval traffic. While mine warfare is still a very important part of naval offense and defense today, the word torpedo has come to mean an underwater projectile or missile, self-propelled with propellers or jets, and aimed at a particular target. Torpedoes can be fired along a pre-determined course or guided in some way. This guidance today can be on-board or remote, in the latter case usually wire-guided much like an antitank missile.
The inventor of the torpedo as we know it was Robert Whitehead, a Lancashire engineer who had long worked on the Continent. He was working in Trieste, then an Austro-Hungarian seaport, when he was essentially head-hunted by another firm, and moved down the coast to Fonderia Metalli de Fiume, in a port city which has had many names and flown many flags over the centuries since Roman historians noted that a tribe of rude Celts lived on the hills and a “more civilized” tribe of mariners lived in the seaport. The Romans called it Tarsatica. By 1856, when Whitehead and his family arrived, the city was known as Fiume in Italian (which many of the inhabitants spoke, regardless of their loyalty to the Dual Monarchy), Fiume in Hungarian (technically, it was part of the Hungary half of the Empire), Sankt Veit am Pflaum in German (the lingua franca of central Europe in those days) and Rijeka to the local Croats, who had to learn one of the other languages — or better yet, all of them — to advance in society and commerce. As an empire, Austria-Hungary was a very different concept from the nations of today; one’s ethnicity was not implicated in his political allegiance to the extent it is in the post-Fourteen Points world.
Fiume was also the location of the Austro-Hungarian Naval Academy, which like any major power’s academy not only trained future naval officers but sponsored research. This included pioneering research in photography, communications, physics, and, more to our point, remote-controlled weapons. Whitehead’s company, now yclept Stabilimento Tecnico Fiumano (Technical Establishment of Fiume), at first made high-tech machinery of the era, such as steam engines for naval ships. They were tied in tightly to the Naval Academy and the local academic community; for example, technicians at what would become the Whitehead torpedo plant provided the first experimental proof of Mach’s concept of the influence of the speed of sound on aerodynamics.
By happy coincidence an officer (Commander — Fregattenkapitän – Giovanni Luppis) was struggling with a remote-controlled surface boat IED he’d invented, which he called the Coast Guard. His surface torpedo — for that is what it was — had a spring-and-clockwork mechanism and steering bridles for control from the shore, and a contact fuze for detonating if someone was lucky enough to guide it onto an enemy ship. Here was a problematic gadget, but the germ of a very good idea, and Whitehead and a talented team including his son John and his right-hand man, Anibale Plöch. Unlike many Victorian Age inventors, Whitehead seldom sought patents, preferring to maintain his technical advantages as trade secrets.
And technical advantages he had.
To make his torpedo work, Whitehead and his team had to solve several problems: propulsion, stability&control, and effect. The last of these was the easiest: a cylindrical bronze torpedo could carry sufficient explosive to sink any modern dreadnought, and, moreover, deliver it below the water line where the ship was most vulnerable. The Empire was well-stocked with talented artillerists and engineers, and neither fuzes nor explosives required research, simply development. That part was basic engineering, not science.
The true developments were propulsive and control based. Whitehead used steam for the first torpedo, and then changed to a compressed-air-powered piston engine, for more power and quicker preparation to fire. The compressed-air engines were made in a variety of designs and layouts.
Of course, the engine is only half of a naval powerplant — the other half is the propeller. These three recovered torpedo tails tell the story of improved propellers (they also show the growing awareness of fluid dynamics. The first torpedo was sharply spiked fore and aft — by the end of the 19th century, a blunter shape with a round nose was proven to generate less hydrodynamic drag).
Devices pioneered here for control were a mechanical depth control and a variety of steering gyroscopes. John Whitehead tried to develop a torpedo gyroscope but his model was a dead end. Instead, they purchased a design from former Whitehead engineer Lodovico Obry. Much of this history is recounted on the Torpedo of Rijeka website.
In the years leading up to the Great War, Whitehead’s company, Torpedofabrik Whitehead AG, was controlled by a British syndicate of the arms and engineering giants Vickers and Armstrong-Whitworth, who’d acquired it on his death in 1905 and continued torpedo development.
After the breakup of the Austro-Hungarian empire at war’s end, the factory was acquired by an influential Italian family, and its name was changed to an Italian one, but cutting-edge torpedo development for all nations resumed. The testing station on the docks had a new level built with a catapult to simulate aerial torpedo launches.
The plant resumed torpedo production again after being bombed by the Allies in World War II, but ceased that production in the 1960s. The physical plant and its distinctive torpedo test tower (alas, not the original from 1866 but the upgrade from the 20th Century) still exist. The enthusiasts of the Torpedo of Rijeka website hope to establish a permanent museum to their city’s most enduring export. Rijeka today is a sun-blessed city on the Adriatic coast of Croatia, and a reasonable European vacation destination.
Whitehead had a most remarkable life. His daughter Alice married the skipper of the Austrian boat that tested and validated his prototype torpedoes; his granddaughter Agnes inherited his vast fortune, and she in turn married an Austro-Hungarian minor nobleman and naval officer that she met at a sub commissioning. The officer would later command that sub and another on his way to becoming the Empire’s top-scoring submarine ace, in which career he naturally used Whitehead torpedoes to sink English and Italian vessels (including an Italian submarine, Nereida, in possibly the first sub-on-sub torpedo battle in history).
You might have heard of the guy, who later emigrated to the United States with their kids after Agnes passed away. His name was Georg, Baron von Trapp.
