Question: What class of battleship was commanded by U.S. Navy officer Robert C. Peniston?
Context: Admiral of the Fleet Sir Arthur Knyvet Wilson, 3rd Baronet (4 March 1842 – 25 May 1921) was a Royal Navy officer.  He served in the Anglo-Egyptian War and then the Mahdist War being awarded the Victoria Cross during the Battle of El Teb in February 1884.  He went on to command a battleship, the torpedo school HMS "Vernon" and then another battleship before taking charge of the Experimental Torpedo Squadron.  He later commanded the Channel Fleet.  He briefly served as First Sea Lord but in that role he "was abrasive, inarticulate, and autocratic" and was really only selected as Admiral Fisher's successor because he was a supporter of Fisher's reforms.  Wilson survived for even less time than was intended by the stop-gap nature of his appointment because of his opposition to the establishment of a Naval Staff.  Appointed an advisor at the start of World War I, he advocated offensive schemes in the North Sea including the capture of Heligoland and was an early proponent of the development and use of submarines in the Royal Navy. Kenneth Whiting (22 July 1881 – 24 April 1943) was a United States Navy officer who was a pioneer in submarines and is best known for his lengthy career as a pioneering naval aviator.  During World War I, he commanded the first American military force to arrive in Europe for combat.  After the war, he was instrumental in development of the aircraft carrier in the United States, where he sometimes is known as the U.S. Navy' s "father of the aircraft carrier."  He was involved in some way in the design or construction of five of the first six U.S. Navy aircraft carriers, and served as acting commanding officer of the first carrier to enter U.S. Navy service and as executive officer of the first two American carriers.  In the earliest days of the U.S. Navy' s development of an aircraft carrier force, he led many shipboard innovations still in use aboard carriers today.

The name was suggested by Lieutenant Robert C. Newcomb, U.S. Navy, navigator of the "Glacier", for Engineman Frederick A. Collins, U.S. Navy, a member of the survey party. Balchunas Pass ( ) is a broad pass between Mount Flint and Mount Petras in the McCuddin Mountains of Marie Byrd Land.

Balchunas, U.S. Navy, Executive Officer for Antarctic Support Activities during Operation Deep Freeze 1971, 1972, and 1973. Robert C. Peniston (October 25, 1922 – August 2, 2014) was a career United States Navy officer who rose to the rank of captain and commanded the battleship USS "New Jersey".
