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.

A national security official under Joe Biden who reviewed the document is said to have turned pale on realising Beijing had “redundancy after redundancy” for “every trick we had up our sleeve”, The New York Times reported.

Last year, Pete Hegseth, the defence secretary, said that “we lose every time” in the Pentagon’s war games against China, and predicted the Asian country’s hypersonic missiles could destroy aircraft carriers within minutes.

Since seawater is radio opaque and visually not very transparent, a submarine meets 2/3 of the criteria of being invisible... which leaves sound and magnetic field (of which the latter is rather local).

So definitely a submarine, but how does it propel itself, and how does it avoid emitting and reflecting sound?

Or perhaps, no large crewed vessels at all, since it's unpopular to lose them to sea drones made with garage level tech.

Perhaps the art of fighting is turning entirely towards small systems, ones that carry just enough to hurt the intended target type badly, and not a kilo more.

China itself seems to be learning lessons. One of their concepts is an unpiloted cargo plane to deploy a drone swarm. Applied to sea and to a situation of projecting power to distance - an uncrewed submarine to deploy a torpedo swarm. It wouldn't return home, just deny a certain part of the sea to opponents. It could be slow, quiet and sleep at the bottom ahead of a conflict - and open up when needed.
