.jpg)
The Roma was an Italian steam-powered tank frigate 1st rank with screw of the Roma class and at the same time the first warship of the Regia Marina named after the capital Rome . It was put into service in 1868. After severe damage from lightning strikes and self-sinking in 1895, it was lifted and demolished in 1896.
history
The Roma was the first of two ships of the same class of 1st rank armored frigates and like her identical sister ship Venezia the first ship of this type to be built in Italy . The armored frigate was also the first warship of the Regia Marina , named after the capital Rome , of the Royal Italian Navy, launched in 1861 .
Like her identical sister ship Venezia, she had a wooden hull with removable 150 mm thick side armor and a 3-way expansion steam engine as a drive . The ship also had three masts , two of them for rectangular square sails and one for Schrat sails, and so was more or less a three-masted tall ship with a steam engine in terms of rigging .
The Roma was put under construction in 1863 at the Foce shipyard in Genoa , and it was launched in 1865. Four years later, in 1868, it was completed and put into service.
After many years of service in the Tyrrhenian Sea and the Adriatic Sea , the Roma got caught in a heavy storm in 1895 and was damaged by lightning, some crew members died and a fire broke out. Since the ship was more damaged than expected, it was sunk a short time later by its own crew near the port. The ship was lifted and demolished in 1896, almost exactly a year later.
commitment
The steam-powered armored frigate Roma saw no war effort. After many years of service in the surveillance of the Tyrrhenian Sea and some voyages in the Adriatic Sea as well as escort for larger units (more rarely also for merchant ships), she later mostly sailed in coastal waters. Roma sank some ships of privateers from North Africa and the Ottoman Empire , which did not surrender without resistance. Until 1881 several missions took place together with her sister ship Venezia from 1873.
