Pisa-class
San Giorgio-class
An item reported that the armour plates of the Italian San Georgia (1) were disapproved when tested. The result was that the Terni plates delivered for the San Marco now were just used for the San Georgia.(1)
Note
1. This must be the San Giorgio-class armoured cruisers consisting of the San Giorgio and the San Marco, preceded by the Pisa-class and built between 1910-1911.
