Document 2: Nimitz-class aircraft carrier: The "Nimitz"-class supercarriers are a class of ten nuclear-powered aircraft carriers in service with the United States Navy. The lead ship of the class is named after World War II United States Pacific Fleet commander Fleet Admiral Chester W. Nimitz, the U.S. Navy's last fleet admiral.

Document 3: Iowa-class battleship: The "Iowa"-class battleships were a class of six fast battleships ordered by the United States Navy in 1939 and 1940 to escort the Fast Carrier Task Forces that would operate in the Pacific Theater of World War II. Four were completed, two more were laid down but canceled in August 1945, at war's end, and both hulls were scrapped in 1958. Like other third-generation American battleships, the "Iowa"s followed the design pattern set forth in the preceding "North Carolina"-class and "South Dakota"-class battleships, which emphasized speed in addition to secondary and anti-aircraft batteries. Based on wartime experience, they were to serve as fast escorts for "Essex"-class aircraft carrier s.
Document 4: USS Nevada (BB-36): USS "Nevada" (BB-36), the second United States Navy ship to be named after the 36th state, was the lead ship of the two "Nevada"-class battleship s. Launched in 1914, "Nevada" was a leap forward in dreadnought technology; four of her new features would be included on almost every subsequent US battleship: triple gun turrets, oil in place of coal for fuel, geared steam turbines for greater range, and the "all or nothing" armor principle. These features made "Nevada", alongside its sister ship "Oklahoma" , the first US Navy "super-dreadnoughts".

She is named in honor of Master Chief Petty Officer Delbert Black, the first Master Chief Petty Officer of the Navy (MCPON), who died in 2000. He is remembered for establishing the role of the Navy's senior enlisted leader, and the ship naming is the culmination of a decade of advocacy by MCPONs to honor him with a combatant ship, believed to be the first time in many decades that a ship has been named for an enlisted person's superior performance and impact, rather than valor or personal sacrifice. "Delbert D. Black" will be the fourth of eight planned Flight IIA "technology insertion" ships, which will contain elements of the Flight III ships projected to begin with DDG-124.

Of all captains in the history of the United States Navy, he is the only one to have been subjected to court-martial for losing a ship sunk by an act of war, despite the fact that he was on a top secret mission maintaining radio silence (the testimony of the Japanese commander who sank his ship also seemed to exonerate McVay). After years of mental health problems, he committed suicide. Following years of efforts by some survivors and others to clear his name, McVay was posthumously exonerated by the 106th United States Congress and President Bill Clinton on October 30, 2000.
