In the build-up to the
First World War, Austria-Hungary ordered four 250–tonne boats to be built at the
Ganz & Co.– Danubius shipyard in 1912/13. The Navy asked for several improvements compared with the Trieste–class boats. Negotiations broke down in early December because of exaggerated prices requested by Danubius and were only resumed when pressured by the Hungarian Minister of Commerce. Danubius lowered its price by 10%. Finally, Ganz & Co. – Danubius got orders for 16 torpedo boats in 1913, despite the fact that original plans had called for the Naval Arsenal Pola to build the Tb 86 to Tb 100 series. These ‘Monfalcone–boats’ were commissioned under the numbers Tb 98 M to Tb 100 M between March 1915 and March 1916. They differed from their Trieste sister–ships having two funnels and an extended forecastle. They were very similar to the Fiume-built ships of the same series. ==Service in the Hellenic navy==
