On 19 March 1931, even before
Arizona was put through post-modernization sea trials, she hosted President
Herbert Hoover for a brief vacation in the Caribbean. The President visited Puerto Rico and the
Virgin Islands. Returning on 29 March,
Arizona conducted her sea trials at
Rockland, Maine, and had another catapult fitted on the top of Turret III, before she was transferred to the
West Coast in August with her sister
Pennsylvania. In February 1932, the ship participated in Grand Joint Exercise No. 4 in which carrier aircraft successfully attacked
Pearl Harbor on Sunday morning, 7 February. After returning to the West Coast from Fleet Problem XIV in 1933, the ship was anchored in San Pedro when an earthquake struck nearby
Long Beach, California, on 10 March. Sailors from the ship joined the relief efforts, providing food, treating the injured, and providing security from looters. In early 1934, the ship and her crew were filmed for the
James Cagney/Warner Brothers film
Here Comes the Navy, which made extensive use of exterior footage as well as on-board location shots. In the early morning of 26 July,
Arizona collided with a
fishing trawler,
Umatilla, that was under tow by another trawler off
Cape Flattery. Two men aboard
Umatilla were killed in the collision and the Navy convened a
Court of Inquiry to investigate the incident. The court recommended that the ship's captain, Captain
MacGillivray Milne, be court-martialed. This took place at Guantanamo Bay Naval Base, Cuba, while the ship was participating in that year's Fleet Problem off the
East Coast. Milne was judged guilty and replaced several months later by Captain George Baum after the ship returned to the West Coast. In the meantime,
Rear Admiral Samuel W. Bryant assumed command of Battleship Division Two on 4 September, with
Arizona as his flagship. Rear Admiral
George T. Pettengill relieved Bryant on 4 March 1935 and the ship participated in Fleet Problem XVI two months later.
Arizona made a port visit to Balboa in May 1936 during Fleet Problem XVII. On 8 June, Captain
George A. Alexander relieved Baum as captain, and, 15 days later, Rear Admiral
Claude C. Bloch relieved Pettengill. During gunnery practice on 24 July, the combustion gases from one gun of Turret II entered the gun turret, burning one crewman. The turret's sprinkling system was turned on to prevent any powder explosion, but the released water leaked into the turret's electrical switchboard and started a small fire that was easily put out. Due to the navy's limited budget, the ship spent most of this period in port as a fuel-saving measure. In
Fiscal Year 1936–37, the ship was anchored for 267 days; the following year it was in port for 255 days. The ship spent the rest of her career based on the West Coast or in Hawaii. on the deck of
Arizona, On 2 January 1937, Rear Admiral
John Greenslade assumed command of Battleship Division Two from Bloch and transferred his flag to the battleship on 13 April. Rear Admiral
Manley H. Simons, commander of Battleship Division One, transferred his flag to
Arizona on 7 August. He was relieved by Rear Admiral
Adolphus E. Watson on 8 November. Captain
Alfred Winsor Brown relieved Baum on 11 December. The ship participated in Fleet Problem XIX off Hawaii in April–May 1938. Captain Brown died in his sleep on 7 September and Captain
Isaac C. Kidd assumed command of the ship on 17 September 1938. That same day, Rear Admiral
Chester Nimitz assumed command of Battleship Division One. Nimitz was relieved on 27 May 1939 by Rear Admiral
Russell Willson. Captain
Harold C. Train assumed command of the ship on 5 February 1940.
Arizonas last fleet problem was off Hawaii in April–May 1940. At its conclusion, the
United States Pacific Fleet was retained in Hawaiian waters, based at Pearl Harbor, to deter the Japanese. She was overhauled at the
Puget Sound Navy Yard,
Bremerton, Washington, from October 1940 to January 1941. During this refit, the foundation for a
search radar was added atop her foremast, her anti-aircraft directors were upgraded and a platform for four water-cooled caliber
M2 Browning machine guns was installed at the very top of the mainmast. Her last flag change-of-command occurred on 23 January 1941, when Willson was relieved by Isaac Kidd, by that time a rear admiral. Captain
Franklin Van Valkenburgh relieved Train on 5 February 1941. On 22 October 1941, during an exercise taking place in heavy fog, the ship was hit in the bow by the .
Arizona had been scheduled to depart for
Bremerton Navy Yard in November to undergo an overhaul. The accident instead required her to be dry-docked at Pearl Harbor for repairs to the collision damage. As a result, she remained in Hawaii. The ship's last
sortie was a night-firing exercise on the night of 4 December as part of Battleship Division One, alongside
Nevada and
Oklahoma. All three ships moored at
quays along
Ford Island on the following day. == Attack on Pearl Harbor ==
