• Sister Ships: Was part of the White Star Line's Olympic class of ships, which included its sister ships: the RMS Olympic and the HMHS Britannic. The Olympic served a long career until 1935, while the Britannic sank during World War I in 1916 after hitting a mine.

• Size and Weight: The Titanic weighed about 52,310 tons and was 882 feet and 9 inches long, nearly as long as three football fields. At the time, it was the largest moving human-made object in the world. It was designed to be a luxury "floating city”, Constructed at the Harland and Wolff shipyard in Belfast, Ireland. Construction took over two years (1909-1911) and involved around 15,000 workers. The ship was launched on May 31, 1911.

• Advanced Safety Features: Had 16 watertight compartments designed to contain water if breached, double-bottom hull designed to contain water if breached. The compartments could be sealed off by watertight doors that closed automatically in the event of flooding.

• The idea was to contain flooding to isolated sections. The ship could theoretically stay afloat if up to four compartments were flooded. However, the iceberg's collision breached six compartments, which sealed Titanic's fate.

• Had 29 boilers feeding 159 coal-burning furnaces. The ship had two reciprocating steam engines and a low-pressure turbine, powering three propellers. It could travel at a top speed of 23 knots (around 26 mph).

Materials:

Made with 3 million rivets holding the steel plates together. The rivets in the ship’s central body were high-quality steel, but the ones in the bow and stern (where the hull curves) were iron, which might have contributed to the hull fracturing more easily on impact with the iceberg.

Titanic had a double bottom, meaning a layer of steel plates lined the bottom of the hull. There was a consideration for a full double hull (up the sides), which would have offered even more protection, but it wasn’t implemented, probably due to cost and weight concerns.
