Recently, when fishermen in Phu An Province, the central province of Vietnam, were fishing in the territorial waters, the fishing net accidentally hung a strange object on the bottom hook, and when they fished it up, they found that it was a large-caliber torpedo with a new appearance and no rust marks!
And as the torpedo came out of the water, more questions followed. It may no longer matter which country the torpedo originally belonged to, but military fans are clearly more concerned about how much progress Vietnam's military industry can make with this torpedo. If Vietnam were to hand it over to other major military-industrial powers, what would be the impact on the situation of underwater combat power between countries?
The picture shows a large-caliber torpedo fished by Vietnamese fishermen, noting the damaged nine-leaf composite large-rolling propeller.
First of all, although torpedoes are much older than missiles, for more than a hundred years, countries that can make torpedoes can be counted on both hands. As the most powerful "top crown" of torpedoes, the manufacturing difficulty and cost of large-caliber thermodynamic torpedoes are not generally large, and the scientific and industrial fields involved cover a complex range of aspects such as acoustics, fluid dynamics, thermodynamics and control theory.
To put it simply, vietnam, a small country that has not completed the "basic course" of heavy industry, needless to say, is a developed country such as South Korea, where science and technology companies are everywhere, and it is quite difficult to take down hot-powered torpedoes.
The picture shows a cross-section of the Russian thermodynamic torpedo propulsion device with an extremely complex structure.
In other words, even if the torpedoes fished by Vietnamese fishermen "for the national trawler" are less difficult electric aviation anti-submarine torpedoes, the Vietnamese are also unable to do anything about it: the Russian-made "Kilo" class submarines previously purchased by Vietnam have long been equipped with TEST71 wire-guided anti-submarine torpedoes, but the Vietnamese military industry, which is good at bragging, has been unable to make a direct torpedo for so many years, which is enough to see the problem.
In addition, judging from the orange marking on the head of this torpedo, this is a "drill mine" for training, and its propulsion section function is still intact, but it does not contain a warhead harmonic self-guidance module, which makes simple "imitation" impossible.
The picture shows the large seven-bladed rolling propeller of a Soviet submarine, which was processed by a high-precision machine tool provided by Toshiba.
But if the torpedo had been "transferred" by Vietnam to a third party with experience in the design of thermodynamic torpedo production, the situation would not have been the same. First of all, through the thruster blades on this torpedo, the country that, after analyzing and testing it, will at least be able to know the relevant level of the country that made the torpedo: as a darling of high-precision processing, materials science and fluid mechanics, the rolling propeller will have a very different effect with just a slight change in angle.
But because of this, the torpedo "pulled" from the seabed to the beach is no longer very significant, because its turn-to-side propeller has obvious leaks and damage.
Pictured is the U.S. Navy's most advanced anti-submarine torpedo in service, the MK.50, with a thermodynamic engine unmatched in the world.
Secondly, although the principle of thermodynamic engine is "well known to the world", through the analysis of the composition ratio of residual fuel and the component structure of thermodynamic engine, it is still quite "educational value" for countries that are relatively backward in this field other than China, the United States and Russia.
However, in the eyes of such "torpedo powers" as China, the United States and Russia, this kind of "ocean fall" that can be encountered and cannot be sought is worth a look, but it will not affect their respective technical routes. Taking the Americans as an example, the lithium-sulfur hexafluoride double-cycle engine used in the MK.50 torpedo is unparalleled in the world, so why "copy other people's work"?

For the legend of "fishing for torpedoes to promote modernization", in fact, there are many versions of the American MK.46 anti-submarine torpedo many years ago, and the location is also located in the South China Sea. But in fact, the premise of "copying homework" is that you must "take the pen", if you can't even hold the pen, you can't write your own chapter, then the delusion of relying on a homework sent from heaven can be better than the "top student", which is undoubtedly a pipe dream.
