Answer the following question: Information: - World WarII (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 WarII the deadliest conflict in human history. - The German Navy (or simply ) is the navy of Germany and part of the unified "Bundeswehr" ("Federal Defense"), the German Armed Forces. The German Navy was originally known as the "Bundesmarine" ("Federal Navy") from 1956 until 1995 when "Deutsche Marine" ("German Navy") became the official name with respect to the 1990 incorporation of the East German "Volksmarine" ("People's Navy"). It is deeply integrated into the NATO alliance. Its primary mission is protection of Germany's territorial waters and maritime infrastructure as well as sea lines of communication. Apart from this, the German Navy participates in peacekeeping operations, and renders humanitarian assistance and disaster relief. - The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, % of the world population at the time, and by 1920, it covered , % of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories. - 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. - German submarine U- 777 was a German Type VIIC U-boat built in World War II , launched on 25 March 1944 , and commissioned on 9 May , by its sole commander , Oberleutnant zur See Gunter Ruperti . - A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Used as an adjective in phrases such as "submarine cable", "submarine" means "under the sea". The noun "submarine" evolved as a shortened form of "submarine boat" (and is often further shortened to "sub"). For reasons of naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size. - The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage. The U.S. Navy has the world's largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 323,792 personnel on active duty and 108,515 in the Navy Reserve. It has 274 deployable combat vessels and more than 3,700 aircraft in active service . - The Kriegsmarine ("War Navy") was the navy of Nazi Germany from 1935 to 1945. It superseded the "Kaiserliche Marine" (German Imperial Navy) of World War I and the inter-war "Reichsmarine". The "Kriegsmarine" was one of three official branchesalong with the "Heer (Army)" and the "Luftwaffe (Air Force)"of the Wehrmacht, the armed forces of Nazi Germany. - 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. - Oberleutnant zur See ("OLt zS" or "OLZS" in the German Navy, "Oblt.z.S." in the Kriegsmarine) is traditionally the first and highest "Lieutenant" grade in the "German Navy". It is grouped as OF-1a in NATO, equivalent to a Lieutenant Junior Grade in the United States Navy, and a Sub-Lieutenant in the British Royal Navy - U-boat is the anglicised version of the German word U-Boot , a shortening of Unterseeboot, literally "undersea boat". While the German term refers to any submarine, the English one (in common with several other languages) refers specifically to military submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding), enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada, the British Empire, and the United States to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. - The Holocaust (from the Greek ': "holos", "whole" and "kaustos", "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 1.5million 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. - 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 8:15a.m. on August 6, 1945, near the end of World War II. What is the relationship between 'german submarine u-777' and 'kriegsmarine'?
