The Loligo, a small submarine intended for science, taken over by the military, not used for either purpose

Loligo

Loligo, prva podmornica na svijetu napravljena isključivo za znanstvena istraživanja. Izgrađena je 1914. u riječkom brodogradilištu Danubius Werft (danas 3. maj) za potrebe mecene P. Schottländera i tadašnje Zoološke stanice u Rovinju (Centar za istraživanje mora Rovinj). Duljina joj je ...

only. According to Wilhelm Donko "Österreichisch-Ungarische Unterseeboote" the acquisition of this sub by the

have needed special infrastructure, like a shore-based charger base, not needed by other types. So its deployment
was regarded as not really worthwhile to the Army Supreme Command. (photo from the above mentioned book)
