Surface debris was found, suggesting the vessel suffered a catastrophic implosion as a result of the immense pressures where it was operating some 10km (6.2 miles) down.

Robot sub... still, a loss.

about 14600 PSI at that depth.

Thanks for posting.
There have been so many manned and unmanned deep research subs over the decades I just did not expect to hear of one failing.

Well, I'm sure it's now in a super compact 'fun size' that's more easily storable.
