An item referred to the magazine Schiffbau reporting that the Austrian battleships Kaiser Fransz Joseph (1) and Tegethoff (2) were armed with 4x3-30,5cm guns and 16 or 20-10,5cm guns. The several magazines however supplied different details concerning the arrangement of the turrets.
1. The Kaizer Franz Joseph I-class protected cruiser consisted of the Kaiser Franz Joseph I and the kaiserin Elisabeth built between 1888-1892 and with a main armament of 2x1-24cm/9.4” guns.
2. The Tegethoff-class consisted of the Viribus Unitis, Tegethoff, Prinz Eugen and Szent István with a main armament of 4x3-30,5cm/12” guns. The name Kaiser Franz Joseph is obvious a mistake.
