Just FYI if you are interested.

The background target ship is a Type 12M Rothesay Class Royal Navy Frigate, then sold to other countries like Oz.
It is only around 2,000 tonnes and designed right after WW2 as an escort frigate.

好震撼的图片,2段了炸.

This is a US Navy Spruance-class destroyer sinking in mere minutes
after being hit by the latest version of a Mk 48: a heavyweight torpedo which,
as you can see in this video, can wipe a whole ship out of the water in a single strike.

This version, developed by the US and Australia,
has new sonar enhancements that make
it an "effective weapon in shallow water and in a countermeasure environment.
" The footage was taken to demonstrate its capabilities
during the Rim of the Pacific 2008 naval exercise. Obviously,
with frightening success (at least for someone who is looking to go to NYC in a freighter ship soon.)
