190 mm/39 (7.48") Skoda
Updated 10 October 2013
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 information.

The data that follows is for these guns while in Austria-Hungary service unless otherwise noted.
