Interesting, could name few trend setting design from the USA navy in the let say last 30 years ?Curious:
Russian Empire/Soviet Union, while both known to occasionally produce innovative naval designs, only occasionally managed to produce trend-setting designs.
All the I can came up:
Zumwalt, with a groundbreaking main gun that hasn't got any ammunition
Ford, that needed 5 years to fix the weapon elevators that using electricity instead of old style hydraulic. Groundbreaking.
Litoral combat ship, that hasn't got any weapon, and has the survavibility of a yacht
Maybe the Burke, that still use the same , 80s vintage radar and targeting system ? Upgraded with commercial computer parts, of course, because saving money is making profit .
Soooooo groundbreaking. Like a money burning furnance.
