List of ships of the Royal Yugoslav Navy
# List of ships of the Royal Yugoslav Navy

The Navy of the Kingdom of Serbs, Croats and Slovenes – from 1929, the Royal Yugoslav Navy (Serbo-Croatian Latin: Kraljevska mornarica; Serbo-Croatian Cyrillic: Краљевска морнарица; КМ) – included a wide range of vessels during its existence from 1920 to 1945. This list includes all sea-going warships ranging from a light cruiser down to motor torpedo boats (MTBs), and also includes river monitors that operated on the Danube and other rivers. Large auxiliary vessels such as submarine tenders and tankers are included, but hulks, tugs and smaller auxiliary craft are not.

The KM was formed in 1920, but it was not until March 1921 that a number of former Austro-Hungarian vessels were transferred, some of which were already obsolete. The only modern seagoing warships transferred were twelve torpedo boats. Little was done to improve the fleet during the 1920s, but fleet modernisation was underway from the early 1930s, with a British-made flotilla leader followed by a class of modern French-designed destroyers and German-built MTBs. Almost all of the fleet was captured by the Axis powers during the April 1941 invasion of Yugoslavia, but a few vessels escaped to form the KM-in-exile, which operated under British supervision. Later in the war, several vessels that had been in Italian service were returned to the KM-in-exile, and these were joined by a British corvette. At the end of the war, these vessels were transferred to the fledgling Yugoslav Navy.

## Coastal defence ship

The former SMS Kronprinz Erzherzog Rudolf had been completed as an ironclad warship in 1889. She was an obsolete coastal defence ship when acquired by the Navy of the Serbs, Croats and Slovenes in 1921, and was scrapped the following year.

## Light cruiser

The former Gazelle-class light cruiser SMS Niobe had been commissioned into the Imperial German Navy in 1900, so by 1941, Dalmacija was obsolete and was being used as a gunnery training ship. Captured by the Italians during the April 1941 invasion of Yugoslavia, she was put into service in the Royal Italian Navy as Cattaro. She was captured from the Italians by the Germans after the Italian armistice with the Allies in September 1943, and served in the German Navy as Niobe. She also served in the Navy of the Independent State of Croatia as Zniam before being lost in December 1943.

Dubrovnik was a flotilla leader built by a British shipyard in 1930–1931. Captured by the Italians in April 1941 she was put into service as Premuda, and was the most important and effective Italian war prize ship of World War II. She was captured by the Germans after the Italian armistice and served as TA32 until she was scuttled near the end of the war.

### Beograd class

The Beograd class were French-designed destroyers completed in 1937–1938. Zagreb was scuttled during the Axis invasion of Yugoslavia, but Beograd and Ljubljana fell into Italian hands. They served with the Italians as Sebenico and Lubiana respectively. Lubiana was lost in April 1943, but Sebenico was captured by the Germans after the Italian capitulation, and saw service as TA43 until she was scuttled at the end of the war.

She saw service with the Italians as Alba then Zagabria before being returned to the KM-in-exile in late 1943. She survived the war and was transferred to the new Yugoslav Navy.

## Torpedo boats

### 250t class

Eight former Austro-Hungarian 250t-class torpedo boats were transferred to the KM in 1921, and were the KM's only modern sea-going warships when it was formed. Two were lost or scrapped prior to World War II, and the rest were captured by the Italians during the 1941 Axis invasion and put into service by them. After the Italian capitulation, two were returned to the KM-in-exile. A further ship was sunk by German aircraft while still in Italian hands, and another was scuttled by her Italian crew. Of the remaining two, one was transferred to the Navy of the Independent State of Croatia and was sunk in 1944, and the other served in the German Navy as TA48 and was sunk in early 1945. The two boats that were returned to the KM-in-exile were transferred to the Yugoslav Navy at the end of the war and served as Golešnica and Cer.

During the April 1941 invasion, one escaped to join the KM-in-exile, while the other was captured by the Italians then scrapped. The boat that escaped was used as an anti-submarine warfare training vessel, and was transferred to the Yugoslav Navy at the end of the war and renamed Tara.

Two were captured by the Germans at the time of the Italian capitulation in September 1943, and were lost in their hands or while serving with the Navy of the Independent State of Croatia. Three were handed back to the KM-in-exile and survived the war to see service in the new Yugoslav Navy.

## Minesweepers

At the time of its formation in 1921, the KM obtained four former Austro-Hungarian Schichau-class torpedo boats that had been converted into minesweepers. Three were discarded soon after, but one served as a training vessel until the April 1941 invasion, at which time she was captured by the Italians. The Germans captured her in September 1943 and she was lost in their hands some time later.
