Ah, if we are just talking about nuclear subs (which makes sense in context), yes, I was also thinking of the diesel-electric types used by Indonesia, Argentina or China that've had some losses this century.For nuclear submarines, in recent years critical failures - to the point the whole vessel is lost or close to it - are very rare... except USSR/Russia. The USA lost a couple in the early Cold War. The USSR/Russia has lost over half a dozen, nearly all after 1980, plus a substantial number of major accidents in repairs or decommissioning.
Not sure about other classes of sub.
