 in January 1921. After meeting up with the Pacific Fleet, Arizona continued on to Peru for a week before the two fleets combined to practice battle maneuvers. After a short return to the Atlantic, which included an overhaul in New York, Arizona returned to Peru in the summer before she began operating from her new home port of San Pedro, California, where she was based until 1940.

For the rest of the 1920s, Arizonas service consisted of routine training exercises. Naval historian Paul Stillwell remarked that "the Pacific years included a great deal of sameness and repetition", and his chronology of the ship's movements is filled with phrases like "torpedo-defense practice", "battle-practice rehearsal", "gunnery practice", "en route to ...", and "anchored at ...". A recurring theme in these years were the annual Fleet Problems, which began in 1923. The first two simulated an attack on the Panama Canal from the west, while in 1925 they attempted to defend the Hawaiian Islands. Other 1920s Fleet Problems included the Caribbean, near Central America, the West Indies, and Hawaii. A highlight of the years came on 27 July 1923, when she participated in President Warren G.

Modernization

Four months after Fleet Problem IX in January 1929, Arizona was modernized at the Norfolk Navy Yard. New tripod masts, surmounted by three-tiered fire-control directors for the main and secondary armament, replaced the old hyperboloid cage masts; the number of 5 inches (127 mm) guns was reduced to 12 and re-positioned one deck higher, and eight 25-caliber 5-inch anti-aircraft guns

Arizonas machinery was almost entirely replaced; her high-pressure turbines were replaced by more powerful geared turbines from the cancelled battleship and six new boilers replaced her originals. Their additional power offset the ship's increased displacement as demonstrated during her sea trials; Arizona made 20.7 knots (11.3 m/s) with 35081 shp at a displacement of 37654 lt.

 shells modified into 797 kilograms (1,757.1 lb) aircraft bombs. Flying at an estimated altitude of 3000 metres (9,842.5 ft), Kagas aircraft bombed from amidships to the ship's stern and were followed shortly afterward by Hiryus bombers which bombed the bow area.

The bombers scored four hits and three near misses on and around Arizona. The near miss off the port bow is believed to have caused observers to believe that the ship had been torpedoed, although no torpedo damage has been found. The sternmost bomb ricocheted off the face of Turret IV and penetrated the deck to detonate in the captain's pantry, causing a small fire. The next forwardmost hit was near the port edge of the ship, abreast the mainmast, probably detonating in the area of the anti-torpedo bulkhead. The next bomb struck near the port rear 5-inch AA gun.

Ammunition magazine explosion

The last bomb hit at 08:06 in the vicinity of Turret II, likely penetrating the armored deck near the ammunition magazines

 located in the forward section of the ship. While not enough of the ship is intact to judge the exact location, its effects are indisputable. About seven seconds after the hit, the forward magazines detonated in a cataclysmic explosion, mostly venting through the sides of the ship and destroying much of the interior structure of the forward part of the ship. This caused the forward turrets and conning tower to collapse downward some 25–30 ft (7.6–9.1 ) and the foremast and funnel to collapse forward. The explosion killed 1,177 of the 1,400 crewmen on board at the time, almost half of the lives lost during the attack. It touched off fierce fires that burned for two days; debris showered down on Ford Island in the vicinity. Ironically, the blast from this explosion also put out fires on the repair ship Vestal, which was moored alongside.

Two competing theories have arisen about the cause of the explosion. The first is that that the bomb detonated in or near the black powder magazine used for the ship's saluting guns and catapult charges. This would have detonated first and then ignited the smokeless powder magazine which was used for the ship's main armament. A 1944 Navy Bureau of Ships

 report suggests that a hatch leading to the black powder magazine was left open, possibly with inflammable materials stocked nearby. The Naval History & Heritage Command explained that black powder might have been stockpiled outside of the armored magazine. This theory is plausible because black powder is easy to ignite and the relatively small amount of explosive filler in the bomb could have easily done so. The alternative explanation is that the bomb penetrated the armored decks and detonated directly inside one of the starboard magazines for the main armament; however, smokeless powder is relatively insensitive to fire and the 14-inch powder bags actually required a black powder pad to ignite the powder. It seems unlikely that a definitive answer to this question will ever be found, however, as the surviving physical evidence is insufficient to determine the cause of the magazine explosion.
