Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Let me just leave this here:

South Korea’s ADD showcases new Supercavitating Torpedo at MADEX 2025

ADD said that the development of this supercavitating torpedo is currently about two-thirds complete, and that after further maturing the torpedo’s stabilization control technology, it will finally secure the design and testing technology of the test body.

...The MRXUUV (Mission Reconfigurable eXtra-large Unmanned Underwater Vehicle) currently under development by ADD could serve as testbed.

According to an interview with the ADD chief researcher, the supercavitating torpedo displayed at MADEX 2025 is an actual tested torpedo, designed in size to fit in a UUV, capable of being guided (in the initial phase of the launch, at low speed), and is being developed to sink enemy main surface ships with ultra-high-speed kinetic energy without a warhead.

The publicly released timeline doesn't line up, but the motivations do.

What would a South Korean torpedo two-thirds of the way through development today have anything to do with a Russian ship sinking off the coast of Spain a year and a half ago?

I’d wager this was Ukraine’s handiwork using conventional or drone weapons.
