Information:  - Naval warfare is combat in and on the sea, the ocean, or any other major body of water such as a large lake or wide river.  - Manning Marius Kimmel ( April 22 , 1913 - on or around July 26 , 1944 ) was a United States Navy submarine officer in World War II and the son of Admiral Husband E. Kimmel . He served as both junior and Executive Officer on several submarines , and finally assumed command of USS Robalo as a Lieutenant Commander . Kimmel was reportedly killed when Robalo was sunk off the island of Palawan . However , the specific circumstances surrounding his death remain unclear .  - 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 attack on Pearl Harbor, also known as the Battle of Pearl Harbor, the Hawaii Operation or Operation AI by the Japanese Imperial General Headquarters, and Operation Z during planning, was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii Territory, on the morning of December 7, 1941. The attack led to the United States' entry into World War II.  - An executive officer (often abbreviated XO) is generally a person responsible for running an organization, although the exact nature of the role varies depending on the organization.  - A submersible is a small vehicle designed to operate underwater. The term "submersible" is often used to differentiate from other underwater vehicles known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both crewed and uncrewed craft, otherwise known as remotely operated vehicles or ROVs. Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery, and underwater videography.  - Husband Edward Kimmel (February 26, 1882  May 14, 1968), nicknamed "Kim", was, at the time of the Japanese attack on Pearl Harbor, a four-star admiral in the United States Navy and Commander-in-chief of the U.S. Pacific Fleet. He was removed from command after the December 1941 attack and reduced to the two-star rank of rear admiral. He retired from the Navy in early 1942.  - 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 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 .
