The Russian nuclear submarines are just crazy big compared to the American ones (or anything made by anyone else for that matter)

Typhoon class has a displacement of 48000 tons.

Los Angeles class has displacement of 6927 tons. Typhoon class is a bit under 7 times bigger. Even the largest American sub (Ohio class) is still less then half the size of a Typhoon (the largest submarines ever built) at 18750 tons

edit: As a side not Russians have mainly moved away from the old Typhoon and replaced it with Borei class which is half the size (24000 tons). Only 1 Typhoon class sub is still in active service.

That's quite massive.

The Japanese I-400-class submarines/submersible aircraft carriers, which I believe are still the largest diesel submarines built, were under 7000 tons.

According to the internet you seem to be right, the Qing-class gets very close but not quite there: wiki lists 6628t, versus 6670t for the for the I-400.
