Used on Austria-Hungary pre-dreadnoughts and armored cruisers of the early 1900s.
Some of these ships were ceded after World War I to Italy, where they were scrapped and the guns then used as coastal artillery and on pontoon GM269.
Nomenclature note: The lengths of these guns were identical, the differences as noted in their designations was strictly the result of the way that each nation measured barrel length. See "Definitions and Information about Naval Guns" for further details.
The data that follows is for these guns while in Austria-Hungary service unless otherwise noted.
In 1918 there was also a planned 19 cm/35 (7.48") gun for a new cruiser and two 1,240 mt (1,220 ton) river monitors which had been laid down in 1917. Guns would have been mounted in twin turrets.

- ^A Note on Sources: Although these projectiles are described in "Naval Weapons of World War One" as having AP Caps ("APC" and "CPC"), this is possibly incorrect. Austro-Hungarian projectiles of this time period had neither AP nor ballistic caps. It was not until about 1910 that the Navy purchased licenses from the British firm of Firth and Sons, Limited, for making such items and it was not 1912-13 that the Navy started refitting existing projectiles with AP caps and ballistic caps. So it would seem unlikely that this gun, introduced into service in 1905, would have had such caps until at least 1912.
- ^Outfit for Sankt Georg was 30 APC, 80 SAPC and 10 shrapnel rounds per gun.
