Ballistics
Armor Model
Overview
The further development of the 1920 battlecruiser became project G3. It differed from its predecessor by having a smaller main gun caliber of 419 mm, shorter length, and smaller displacement. In early 1921, the project was redesigned to enhance the armor at the expense of its speed and main caliber characteristics. In October of the same year, the construction of four ships under this project was ordered, but it was suspended amid the start of the Washington Naval Conference. Following its results, the construction order was canceled.
