LOL, imagine a submarine traveling at Mach 1 under water... :)
That's 1224 km per hour ( or 761 miles per hour)
The speed of sound in seawater is around 1500m/s or 5400 km/hr. Something tells me they won't actually be going supersonic.
The article shouldn't be referencing the speed of sound without specifying the medium for the sound waves and conditions such as temperature for water or temperature and pressure for air.
Also, the supercavitation would be incredibly noisy underwater, and at those speeds the vessel itself would produce a very loud pressure wave that would be easy to detect. So its advantage wouldn’t be in avoiding detection, it would be in moving fast enough that detection doesn't matter because no torpedo could intercept them.
Thanks, didn't think about that.
Maybe they can make torpedoes using the same tech....
Torpedoes rely on sonar for targeting, so as long as they travel below the speed of sound in seawater…
