China's SCS Strategy Thread

[plawolf]

Only problem with that theory is that concrete is heavier than water. Fill a shipping container with concrete and it will sink to the bottom.

Leave enough buoyancy in the container to float and that doesn’t leave you with much concrete. Not to mention the inconvenient fact that shipping containers are not made to the highest of specs or design tolerances. So even if you put in the right amount of concrete, they can easily just leak and sink or corrode and sink.

Even if China was silly enough to do that, it would need to do it on a massive scale for have any effect, and I’m sure the Americans would be blasting news of this all over the MSM if so as further evidence of Chinese bad behaviour.

Interesting theory: USS Connecticut (SSN-22) hit a container. PLA using container like mine but without explosives. lol, love it

Eh, this is pretty stupid, the container would need to be filled with tungeston entirely or something. The Seawolf class submarines are gigantic, most small objects like containers would just bounce off due to the sheer difference in mass. A Seawolf class is 12,000 tons, shipping containers on the other hand the largest shipping containers when filled with water would only be around 400. barely enough to notice if you were to bump into one.

Kinetic energy of 400 ton container (4000000 kg) bumping into something moving at 10 knots (5 m/s) is 5 MJ. That's not a negligible amount of energy.

Walking into a pole still hurts, after all.

Not enough to cause the sort of damage reported, namely the front of the submarine being crumpled and the ballast tank damaged.

Got some calculations to back that?

5 MJ is about 1 kg TNT or about the energy of a mortar shell on contact.

In hunt for red october they sailed head on into a torpedo at full speed and nothing happened... not even a dent

Please don’t apply movie logic to real life.

The sonar domes are mostly plastic since they need to allow sound waves to move through with minimal possible distortion for the sonar to work to best effect.

China literally bricked a submarine. HAHA!

The steel used on Seawolf class submarines is HY100, it can withstand 100 KSI. It is made to survive far more than 1 kg of tnt, think 500KG (mk48 torpedo)

Reminder that the ballast tanks were damaged, not just the sonar array.
