Direct answer: Tutorial:_FAQ

"Be aware that any modernization stat bonuses will be lost upon remodelling. Stats that cannot be increased via modernization (evasion, anti-sub, line-of-sight) will be recalculated to match the level upon remodelling so you do not need to worry about potential permanent stat losses due to remodelling late. Modernizable stats (firepower, torpedo, AA, armor) will revert to the ship's base stats plus stat gains from its level."
