Project history

Built by Danubius, Fiume, they were virtually the same type as the Tb I class, the only external difference being the searchlight platforms situated on the CT, while the STT boats had their searchlight fitted before the forward funnel. Much more significant was the fact that the Danubius units had a different boiler system, different main and auxiliary machinery, shafts and propellers. It was necessary for reasons of internal politics to let Hungarian industry (represented by Danubius and its Hungarian subcontractors) participate, bur from the point of view of spare part standardization and supply it was without question an unfortunate solution. Another deficiency of this group was the heavy angle of heel which developed at high speed caused by the turning moment of the single propeller; through inexperience the yard was unable to anticipate this and take steps to counter it in the design.

Modernizations

None.

Naval service

All boats survived active war service and were allocated to Italy and scrapped in 1920 (with the exception of No.7 which served the Italian customs until 1926). No.11 suffered a mutiny and was hijacked by her crew on 5 October 1917 after the crew had imprisoned the two officers. The boat crossed the Adriatic and surrendered to the Italians, who commissioned her as Francesco Rismondo; she was stricken in 1925.
