Chinese submarine underwater

Yes indeed.  A Chinese submarine is underwater.  Unfortunately for the Chinese it is not a finished submarine.  Per the AP

Sub underwater

Just an early test, nothing to worry about, commrad.

As a former Journeyman Outside Machinist, Sub construction, I joke with my current co workers. "Anybody can make a boat that will sink; we had to make 'em come back UP!"

And that made  me think of the Chinese army sourcing supplies from Temu in general.

I needed that laugh.  Thank you.

The idea of building a submarine with Chinesium components is a bit scary. Funny, but scary.

Satellite photo clearly showing the cause of the sub's demise:

Reminds me of the movie 1941 (I likes the movie, very funny, from a historical perspective at least, the movie is NEVER played anywhere though):

(after shooting at Japanese submarine with 40mm AA gun, that ended up in the living room of a house):

"I think we hit him"

   "How do you know"

"He's going down"

I can't find that scene, but here is one (in poor quality) from within the sub.  Some good Slim Pickins stuff here (please note that everyone understands everyone else on the submarine despite speaking Japanese, German and English):

Here is where they emplace the gun (but not the scene where they shoot at the sub).  You might recognize a few actors here:

Maybe it's the new Chines method of Reverse Pressure Testing.  Sink it, pump in air and look for bubbles.  GENIUS!!

Pick one:

Drain plugs?  I thought you said they were in.

When I said screen door on a submarine I was kidding.

Please pay attention to the door ajar light

That's OK, just take a picture before it sank and we can sell to North Korea

A serious option.  Their scheme to prop up their economy via real estate and construction is faltering. 

Defense spending never sleeps, though.  They'll just build a new one 

In reply to 1988RedT2 :

Or vacation hijinks gone wrong?

They probably just followed their own directions on how to assemble it.

It happens...

On 15 May 1969, Guitarro was moored in the Napa River at Mare Island Naval Shipyard while construction was still underway. At about 16:00, a civilian nuclear construction group began to calibrate the aft ballast tanks, which required them to fill the tanks with approximately 5 short tons (4.5 t) of water. Within 30 minutes, a different, non-nuclear civilian construction group began an assignment to bring Guitarro within a half-degree of trim; this entailed adding water to the forward ballast tanks to overcome a reported two-degree up-bow attitude. Until shortly before 20:00, both groups continued to add water, unaware of each other's activities.[1]

Twice between 16:30 and 20:00, a security watch advised the non-nuclear group that Guitarro was riding so low forward that the 1.5-foot-high (0.46 m) wakes of boats operating in the Napa River were sloshing into the sonar dome manhole, but the group ignored the warnings. At 19:45, the non-nuclear group stopped adding water to the ballast tanks and began to halt work for their meal break, leaving at 20:00. At 19:50, the nuclear group completed their calibrations and began to empty the tanks aft.[1]

At 20:30, both the nuclear group, still aboard, and the non-nuclear group, returning from their break, noticed Guitarro taking a sudden down angle which put the forward hatches underwater. Massive flooding took place through several large open hatches. Efforts between 20:30 and 20:45 to close watertight doors and hatches were largely unsuccessful because lines and cables ran through the doors and hatches, preventing them from closing. At 20:55, Guitarro sank, leaving only her sail above water, earning her the nickname "Mare Island Mud Puppy".[1]
