Stabilimento Tecnico Triestino

STT was merged with another Italian shipbuilding firm, Cantiere Navale Triestino, in 1929 to form Cantieri Riuniti dell'Adriatico (CRDA).

Stabilimento Tecnico Triestino had its origins in a private shipyard founded by Gaspare Tonello at San Marco, on the coastline west of Trieste, in 1838.

He asserted that industry was financing the construction of two dreadnoughts on speculation; this was completely untrue, and both STT and Skoda were extremely nervous about the subterfuge.

The company had its own plant in Muggia for the manufacturer of engines and boilers, and a licence from the United Kingdom to produce Parsons steam turbines.

After the Austro-Hungarian Empire broke up at the close of World War I, the region of Trieste was ceded to Italy and Austriawerft became an Italian firm, whereupon its original name, Stabilimento Tecnico Triestino, was restored.

CRDA Trieste built a number of light and heavy cruisers for the Regia Marina Italia (Royal Italian Navy) between the wars, as well as some 27 submarines.
