Modernizing and Upgrading are not the same thing.

Modernizing is taking equipment off of other ships and putting it onto another ship for increased stats.

Upgrading is actually physically changing the ship itself. Remaking it into a new ship. This is where we get -Kai labels from. Some ships that either had historical significance (Yuudachi in the Solomons, HIbiki/Verniy) or just because (Torp sisters, Kongou/Hiei) get another upgrade, resulting in a Kai 2 form, usually at very high levels (Verniy.....)

I'm sure there's reasons for Kongou, torp sisters, and other ships w/o historical references getting a 2nd kai, but I can't remember. If you're really curious, could go read the actual wiki for it..
