By 1855, a screw-powered ship-of-the-line was under construction in Pola after failed bids to construct the ship with British and American shipbuilding firms, while two screw-frigates and two screw-corvettes were being built in Trieste and Venice respectively. Within a year of Ferdinand Max's promotion to "Oberkommandant", the Austrian Navy consisted of four frigates, four corvettes, and two paddle steamers in active service in the Mediterranean Sea. Ferdinand Max followed up on this progress however by purchasing the steam frigate from the United Kingdom in 1856. Her design was used for the construction of future ships of the Navy, and marked the beginning of Austria's modern shipbuilding industry. From 1856 onward, a majority of Austria's ships were constructed by domestic shipyards. Ferdinand Max's next construction project was the last Austrian ship-of-the-line, . She was commissioned into the Austrian Navy in 1859 after being constructed at the newly built Pola Navy Yard between 1855 and 1858.
