Do you have detail armour of I3 for comparison with G3?OK.
I'm skeptical of the I3's as designed, as the armor belt isn't thick enough; you'd need to considerably upscale the engines (and thus dimensions, displacement) to give it adequate protection. But it's hard to say what such an I3 design might have looked like in the end.
Whatever it ended up being, it still would have been of less value than the same resources devoted to fleet carriers in 1939-45. Not that this was immediately evident in 1920-22.
