Q:Information:  - During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack.  - The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.  - The United States Maritime Service (USMS) was established in 1938 under the provisions of the Merchant Marine Act of 1936. The mission of the organization is to train people to become officers and crewmembers on merchant ships that form the United States Merchant Marine per Title 46 U.S. Code 51701. Heavily utilized during World War II, the USMS has since been largely dissolved and/or absorbed into other federal departments, but its commissioned officers continue to function as administrators and instructors at the United States Merchant Marine Academy and the several maritime academies.  - The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, passed by Congress on June 29, 1936, and replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet.  - Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15 a.m. on August 6, 1945, near the end of World War II.  - USNS Kingsport ( T - AG - 164 ) was built as SS Kingsport Victory , a United States Maritime Commission VC2 - S - AP3 ( Victory ) type cargo ship . During the closing days of World War II the ship was operated by the American Hawaiian Steamship Company under an agreement with the War Shipping Administration . After a period of layup the ship was operated as USAT Kingsport Victory by the Army under bareboat charter effective 8 July 1948 . When Army transports were transferred to the Navy 's Navy 's Military Sea Transportation Service the ship continued as a cargo transport as USNS Kingsport Victory ( T - AK - 239 ) . On 14 November 1961 , after conversion into the first satellite communication ship , the ship was renamed Kingsport , preclassifird as a general auxiliary , and operated as USNS Kingsport ( T - AG - 164 ) . Assigned to duty supporting the U.S. Army Satellite Communications Agency USNS Kingsport was further modified and , in August 1963 while in Lagos harbor , transmitted the first satellite voice call between heads of state when John F. Kennedy and Nigerian Prime Minister Abubakar Balewa aboard Kingsport spoke in a two - way call . A demonstration of transmission of oceanographic data was made between a research vessel off Africa via the ship and satellite to Washington . The first air to ship satellite communication took place when Navy aircraft off Virginia established voice communication with Kingsport which was off Morocco . Further satellite communications work took place in the Pacific and Indian Oceans . Kingsport then supported Project Gemini into March 1966 . After conversion from satellite configuration , particularly removal of the large and very visible dome , Kingsport was engaged in acoustic work for the Navy supporting undersea surveillance programs .  - The Holocaust (from the Greek ': "hólos", "whole" and "kaustós", "burnt"), also referred to as the Shoah"' (Hebrew: , "HaShoah", "the catastrophe"), was a genocide in which Adolf Hitler's Nazi Germany and its collaborators killed about six million Jews. The victims included 1.5 million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany.  - Vice Admiral Emory Scott Land (January 8, 1879  November 27, 1971) was an officer in the United States Navy, noted for his contributions to naval architecture, particularly in submarine design. Notable assignments included serving as Chief of the Navy's Bureau of Construction and Repair during the 1930s, and as Chairman of the U.S. Maritime Commission during World War II.  - The War Shipping Administration (WSA) was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the US needed for fighting the war. Both shipbuilding under the Maritime Commission and ship allocation under the WSA to Army, Navy or civilian needs were closely coordinated though Vice Admiral Emory S. Land who continued as head of the Maritime Commission while also heading the WSA.  - The United States Merchant Marine refers to either United States civilian mariners, or to U.S. civilian and federally owned merchant vessels. Both the civilian mariners, and the merchant vessels, are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports cargo and passengers during peacetime; in times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military. Merchant Marine officers may also be commissioned as military officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the Naval Reserves.  - World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.
