Arktika-class icebreaker
The "Arktika" class is a Russian (former Soviet) class of nuclear-powered icebreakers. Formerly known as "Project 10520 nuclear-powered icebreaker", they were the largest and most powerful icebreakers until the 2016 launch of the ship named Arktika. Ships of the "Arktika" class are owned by the federal government, but were operated by the Murmansk Shipping Company (MSCO) until 2008, when they were transferred to the fully government-owned operator Atomflot. Of the ten civilian nuclear-powered vessels built by Russia (and the Soviet Union), six have been of this type. They are used for escorting merchant ships in the Arctic Ocean north of Siberia as well as for scientific and recreational expeditions to the Arctic.
RMS Titanic
The wreck of "Titanic" was discovered in 1985 (more than 70 years after the disaster), during a US military mission and remains on the seabed. The ship was split in two and is gradually disintegrating at a depth of . Thousands of artefacts have been recovered and displayed at museums around the world. "Titanic" has become one of the most famous ships in history; her memory is kept alive by numerous works of popular culture, including books, folk songs, films, exhibits, and memorials. "Titanic" is the second largest ocean liner wreck in the world, only beaten by her sister , the largest ever sunk, although she holds the record as the largest sunk while actually in service as a liner due to "Britannic" being used as a hospital ship at the time of her sinking. The final survivor of the sinking, Millvina Dean, aged two months at the time, died in 2009 at the age of 97.
