The Royal Yugoslav Navy (Kraljevska mornarica) operated a modest fleet during the inter‑war period (1918‑1941). Available encyclopedic sources record the following principal warships, organised by type. The list is not exhaustive; many auxiliary and training vessels are omitted because reliable details are scarce.
Light cruiser
- Dalmacija – A former Austro‑Hungarian protected cruiser (originally SMS Niobe) acquired after World War I and used as a training and flag‑ship vessel.
Destroyers
- Velebit – One of three destroyers ordered from the United Kingdom in the late 1920s; commissioned in 1931.
- Dubrovnik – Sister ship to Velebit; commissioned in 1931.
- Beograd – Third destroyer of the class; commissioned in 1932.
Submarines (built domestically in the 1930s)
- Uskok – Launched 1938; the first of a trio of S‑class submarines.
- Osvetnik – Launched 1938; second of the class.
- Smeli – Launched 1939; third of the class.
River monitors (designed for operations on the Danube and other inland waterways)
- Sava – Former Austro‑Hungarian monitor transferred after World War I.
- Drava – Another ex‑Austro‑Hungarian monitor retained in Yugoslav service.
Torpedo boats / Motor gunboats (selected examples)
- T‑1 through T‑6 – Small fast vessels built in the 1930s for coastal patrol and escort duties.
Auxiliary and training ships (representative entries)
- Zmaj – Naval academy training ship, originally a merchant vessel converted for cadet instruction.
- Srbija – Fleet auxiliary used for logistics and personnel transport.
Notes
- The Royal Yugoslav Navy’s fleet was relatively small compared with its neighboring powers and was largely composed of vessels inherited from the Austro‑Hungarian Navy, supplemented by limited indigenous construction during the 1930s.
- All listed combat ships were lost, captured, or scuttled during the Axis invasion of Yugoslavia in April 1941; surviving hulls were subsequently taken into service by the occupying forces or scrapped after the war.
- Because contemporary naval registers and archival records are fragmentary, the above enumeration reflects the vessels most consistently documented in reputable naval histories and reference works. Additional smaller craft (coastal patrol boats, mine‑layers, support vessels) existed but lack comprehensive, verifiable documentation in the public domain.
