Or any deep dive coming out of overhaul. One week you're sitting in drydock with half the hull penetrations removed and the next week you're hoping they were put back in properly.

Lol @ argentina having subs. What, do they need to periodically check on the rest of their fleet at the bottom of the ocean?

I’m not sure I buy the underwater wave theory. They were sitting at periscope depth for a torpedo exercise. From that position either flooding in through the torpedo tubes or depth excursion causing water influx through the snorkel mast seem more likely than a natural cause sucking the sub below crush depth.

Me neither. In oceanography they're called near-inertial waves with the main velocity occurring in the horizontal plane. Google says the Java Sea can have them up to 2 meters a second or nearly 4 knots. The highest near-inertial wave vertical velocity I could find, assuming one could force a sub deeper, was 0.6 meters per second about 1 knot. Not near enough force to drive a controlled sub deeper. Near-inertial waves also decay with depth.

The statement about under water waves being a suspected cause was likely a face saving measure. Otherwise, in naval history I'd expect more occurrences, catastrophic or not, would have been reported by different navies world wide.
