SS "Kiche Maru" was a Japanese steamship that sank during a typhoon on 22 September 1912.
 Although more than 1,000 people died, the disaster has been overshadowed by the earlier loss (on 15 April 1912) of  , and by the fact that it was part of the casualties of a tropical storm in Southern Japan.
 Although the sinking of a ship was reported (as the ""Kieko Maru"," the ""Keiko Maru"", the ""Kioko maru"" and the ""Kickermaru"" in later accounts), it was in conjunction with a violent storm that sank hundreds of vessels.
 The destroyers "Fubuki" and "Tachibana" were sunk in Ise Bay, and the cities of Osaka and Nagoya sustained heavy damage.
 "Kiche Maru", a passenger ship, foundered off the island of Honshū, and there were no survivors.
Hudson Joshua Creighton Allison (December 9, 1881 – April 15, 1912), his wife, Bess Waldo Allison (née Daniels) (November 14, 1886 – April 15, 1912), their daughter Helen Loraine Allison (June 5, 1909 – April 15, 1912) and son, Hudson Trevor Allison (May 7, 1911 – August 7, 1929) were 1st class passengers on board the RMS "Titanic", which struck an iceberg and sank on April 15, 1912.
 Only Trevor survived.
Operation CHASE (an acronym for "Cut Holes And Sink 'Em") was a United States Department of Defense program for the disposal of unwanted munitions at sea from May 1964 until the early 1970s.
 Munitions were loaded onto ships to be scuttled once they were at least 250 miles offshore.
 While most of the sinkings involved conventional weapons, four of them involved chemical weapons.
 The disposal site for the chemical weapons was a three-mile (five km) area of the Atlantic Ocean between the coast of the U.S. state of Florida and the Bahamas.
 The CHASE program was preceded by the United States Army disposal of 8,000 tons of mustard and lewisite chemical warfare gas aboard the scuttled SS "William C. Ralston" in April 1958.
 These ships were sunk by having Explosive Ordnance Demolition (EOD) teams open seacocks on the ship after they arrived at the disposal site.
 The typical Liberty ship sank about three hours after the seacocks were opened.
Benjamin "Ben" Guggenheim (October 26, 1865 – April 15, 1912) was an American businessman.
 He died aboard  when the ship sank in the North Atlantic Ocean.
 His body was never recovered.
RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City.
 There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history.
 The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line.
 The Titanic was built by the Harland and Wolff shipyard in Belfast.
 Thomas Andrews, her architect, died in the disaster.
The sinking of the RMS "Titanic" occurred on the night of 14 April through to the morning of 15 April 1912 in the North Atlantic Ocean, four days into the ship's maiden voyage from Southampton to New York City.
 The largest passenger liner in service at the time, "Titanic" had an estimated 2,224 people on board when she struck an iceberg at around 23:40 (ship's time) on Sunday, 14 April 1912.
 Her sinking two hours and forty minutes later at 02:20 (05:18 GMT) on Monday, 15 April resulted in the deaths of more than 1,500 people, which made it one of the deadliest peacetime maritime disasters in history.
The "Olympic"-class ocean liners were a trio of British ocean liners built by the Harland & Wolff shipyard for the White Star Line during the early 20th century.
 They were "Olympic" (1911), "Titanic" (1912), and "Britannic" (1915).
 All three were designed to be the largest and most luxurious passenger ships in the world, designed to give White Star an advantage in the transatlantic passenger trade.
 Two were lost early in their careers: "Titanic" sank in 1912 on its maiden voyage, after hitting an iceberg in the North Atlantic Ocean, and "Britannic" in 1916, after hitting a mine laid by the minelayer submarine "U-73" in a barrier off Kea in the Aegean Sea during World War I.
 "Olympic", the lead vessel, had a career spanning 24 years and was retired in 1934 and sold for scrapping in 1935.
Edward Austin Kent (February 19, 1854 – April 15, 1912) was a prominent architect in Buffalo, New York.
 Kent died on April 15, 1912 when the RMS Titanic sank and was seen helping women and children into the lifeboats.
RMS "Atlantic" was a transatlantic ocean liner of the White Star Line that operated between Liverpool, United Kingdom, and New York City, United States.
 During the ship's 19th voyage, on 1 April 1873, she ran onto rocks and sank off the coast of Nova Scotia, Canada, killing at least 535 people.
 It remained the deadliest civilian maritime disaster in the North Atlantic Ocean until the sinking of  on 2 July 1898 and the greatest disaster for the White Star Line prior to the loss of "Titanic" in April 1912.
PS "Ireland" was a paddle wheel steamship of the White Star Line, built in 1891.
 Together, with her sister ship  , she tendered the various White Star Liners which came through the port of Queenstown, Ireland (now Cobh).
 Like her sister ship, "Ireland" is best known for her assistance of the  , the ill-fated ocean liner who made her final port of call at Queenstown on her maiden voyage.
 "Ireland" brought Irish immigrants to the "Titanic", followed by "America", who brought 123 passengers.
 The "Titanic" sank on April 15, 1912, with three-fourths of her maiden voyage completed.
