Project history

Built at the Danubius yards in Porto Ré (Kraljevica) and Bergudi (Brgud), these boats were the Danubius version of the STT 250t boats and differed in the make of turbines and in having two funnels instead of one. Originally Danubius were to have built only four boats, but after having reduced their price by about 10% 16 boats were ordered.

They saw active service in the war and all boats survived. Tb 82-Tb 84 were allocated to Rumania in 1920. The Fulgerul capsized and sank on 8 February 1922 in a heavy gale in the Black Sea during her transfer to Rumania. Naluca was sunk by Soviet bombers in the harbour of Constanza in 1944 and the Zmeul was in service until 1958. Tb 85-Tb 86 and Tb 88-Tb 91 were sold to Portugal in 1920 and renamed Zezere, Ave, Cavado, Sado, Liz and Mondego. Zezere and Cavado ran aground between Tunis and Algier on 29 December 1921 while being towed to Portugal. Liz was stricken in 1934, Mondego in 1938, Sado in 1940, while Ave ran aground and was lost in the same year. Tb 92 was sold to Greece in 1920 and renamed Panormos, as were Tb 94 and Tb 95, which were renamed Proussa and Pergamos. Panormos was stranded in 1928 and sunk; Proussa was hit by German bombs on 4 April 1941 and scuttled, while Pergamos was scuttled on 25 April 1941 when laid up for repairs in me Greek Navy yard at Salamis. Tb 87 was allocated to Yugoslavia in 1920 and was renumbered T 5, as were Tb 93 which became T 6, Tb 96 which became T 7 and Tb 97 which became T 8. All were taken over without changing their designations by the Italian Navy in April 1941; T 6 was scuttled on 11 September 1943; T 8 was sunk on 10 September 1943 by German bombers; the other two became part of the navy of the independent Croatian stale; T 7 stranded after a naval action with a British MTB on 25 June 1944 and was lost, while T5 served as Cer in the Yugoslavian Navy until 1963.
