The Virginia class is basically a cheap mass produced version of the Seawolf submarine of the late Cold War. It has worse top speed, dive depth, and noise levels than the Seawolf. They replaced the electronics with off the shelf hardware to lower costs, and they added more modern sensors. There is nothing particularly special about the Virginia class, it is just that it has been produced in larger numbers than any other attack submarine.
One good evidence of how obsolete the Virginia class is, in particular its electronics and combat systems, is if you compare crew sizes of the Virginia class and the Yasen-M class. 135 vs 64. The Virginia class is way less automated than the Yasen-M class so it needs twice the crew. And it has worse top speed, dive depth, and questionable noise levels. The Virginia class weapons payload is also worse. It can only carry the subsonic Tomahawk, and the Yasen-M can carry all the versions of the subsonic Kalibr (including anti-submarine ones), the Oniks Mach 3 cruise missile, and soon the Zircon Mach 10 cruise missile. The Virginia class also has less VLS cells and torpedo tubes than the Yasen-M.
As for the US Ohio class SSBN it dates from the Cold War period. It is a 1970s design so I do not know why
@tphuang thinks it is all that good.
