Ship models size comparison

I want to create a ship model size comparison, but the 3D model viewer lacks a grid or ruler tool. How can I accurately determine the ship's dimensions?

For examples, 3D model of Shimakaze and Khabarovsk:

It appears they are about the same size, which is not accurate.

use blender if u want create ship model size comparison

I'll think about how I can make a grid in the Viewer..

Data from game hidden files. And analysis of the size data provided by the game
