Information:  - 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.  - 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 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.  - USNS Short Splice ( T - AK - 249 ) was a United States Maritime Administration C1 - M - AV1 type coastal cargo ship , originally planned as an Alamosa - class cargo ship . Constructed as Short Splice for the Administration , completed in August 1945 and placed in operation by the War Shipping Administration during the closing period of World War II. However , the war ended , and she was transferred to the U.S. Army as USAT Short Splice who kept her in service until transferred to the U.S. Navy in 1950 .  - 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.  - 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 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.    Given the information, choose the subject and object entities that have the relation of 'operator'.
