A supersonic submarine?

China has moved a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours.

New technology developed by a team of scientists at Harbin Institute of Technology's Complex Flow and Heat Transfer Lab has made it easier for a submarine, or torpedo, to travel at extremely high speeds underwater.

Li Fengchen, professor of fluid machinery and engineering, said the team's innovative approach meant they could now create the complicated air "bubble" required for rapid underwater travel. "We are very excited by its potential," he said.

Seems rather impractical.

Could be ugly if the sub has a whale strike.

The same was said about things like the steam engine.

The applications for this are way more than speed travel, though. If they can form the bubble like they say, whose to say we can't make a machine that would be able to maintain pressure within a certain radius? suddenly deep sea exploration, or living, becomes possible.

I don't think you understand the physics at play. This is not a locally sustainable effect, and furthermore it's not designed to reduce the pressure around the sub, just the friction.

will kill so many fish

They'll modify a cow catcher for the front

Maybe put some of those deer whistles on the front

That's not of any concern to Asians.
