Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
Maritime history of the United Kingdom
The "Titanic" and her sister ships "Olympic" and "Britannic" were built the White Star Line to outdo the "Mauritania" and "Lusitania" which belonged to the rival Cunard Line. "Titanic" was 269 m long and weight 46,000 tons. She was described as a luxury hotel at sea and as "unsinkable". She was fitted with a double bottom and 16 watertight compartments so that even if two were flooded she would not sink. "Titanic" departed from Southampton on 10 April 1912 on her maiden voyage to America. She called at Cherbourg and then Queenstown (now Cobh) before heading for New York City. Despite warnings of icebergs, she continued at on the night of 14 April. About midnight she hit an iceberg and five compartments started to flood. Two hours afterwards she sank. There were only enough lifeboats for half the passengers and 1,503 people perished. In 1985 her wreck was identified by sonar 4,000 m down and explored using a remotely operated vehicle (ROV). Some objects from the wreck have been recovered.
