What is different from the many previous transits made through this region.

Many? Question is if there were ANY. Traveling Guam-Brisbane is not exactly routine for nuclear subs.

I suspect this may have been the first time this route was traveled by a submarine that deep.

It's not? Better tell the Navy. They say it is routine.

FYI, Guam is homeport to several subs and home-away-from-home for others. Brisbane is a routine liberty port.
