Why Was the USS Arizona Important to History?

The USS Arizona holds a unique place in American history as both the single deadliest loss of the Pearl Harbor attack and a war grave that remains in the waters of Pearl Harbor to this day. Of the 2,403 Americans killed on December 7, 1941, 1,104 died aboard the Arizona alone, nearly half the total. No other single event in the attack concentrated so much loss in one place, and no other ship from that day still serves as both a tomb and a national memorial visited by millions.

A Frontline Battleship on Battleship Row

The Arizona was a 31,400-ton Pennsylvania-class battleship, commissioned in October 1916 and modernized between 1929 and 1931 with upgraded armament and protection. By December 1941, she was one of eight battleships moored along what was known as “Battleship Row” on the southeast side of Ford Island in Pearl Harbor. She sat at berth Fox 7, with the repair ship Vestal tied alongside her port side and Ford Island’s northeastern shore to starboard.

Her position made her a prime target. Japanese horizontal bombers flew in formations of five at roughly 10,000 feet, approaching from the south and running parallel to Battleship Row. Each plane carried a single modified 15-inch naval armor-piercing shell weighing about 1,700 pounds, and all five in a formation released simultaneously, hoping to land one to three hits on the warships below.

The Explosion That Changed the War’s Meaning

Just before 8:00 a.m., the Arizona’s air raid alarm sounded and the crew was ordered to general quarters. During the attack, the ship was struck by as many as eight bombs. One of the armor-piercing shells penetrated the deck near the Number 2 gun turret and detonated inside the forward powder magazine, where massive stores of smokeless and black powder were kept. The resulting explosion was catastrophic, destroying the entire forward section of the ship and igniting a fire that burned for two days.

Forensic analysis by the U.S. Naval Institute later traced the chain of destruction through the ship’s internal compartments, showing how the blast migrated from one magazine to the next through the tightly packed forward spaces. The explosion was so violent that it lifted the bow out of the water before the ship settled to the harbor floor. Of the 1,104 crew members killed, many were trapped below decks and never recovered. Their remains are still inside the hull.

That single explosion accounted for roughly 46 percent of all Navy deaths at Pearl Harbor. It became the defining image of the attack: newsreel footage of the Arizona’s massive fireball and billowing smoke was broadcast across the country and played a direct role in galvanizing American public opinion in favor of entering World War II. Congress declared war the following day with only one dissenting vote.

A Ship That Became a War Grave

After the attack, much of the Arizona’s usable armament and topside structure was salvaged. Her two rear triple 14-inch gun turrets were removed and transferred to the Army for use as coastal defense batteries on Oahu. But the hull itself was too badly damaged to raise and rebuild. Unlike most of the other battleships on Battleship Row, the Arizona was never returned to service. She was stricken from the Naval Vessel Register in 1942 and left where she sank.

That decision, driven by practicality, ended up creating something unprecedented: a permanent underwater tomb holding over a thousand sailors and Marines. The wreck sits in about 40 feet of water, with portions of the superstructure still visible above the surface. More than 80 years later, the ship continues to release small quantities of fuel oil into the harbor, visible as an iridescent sheen on the water. Researchers studying this slow leak have found it offers a rare case study in the long-term behavior of petroleum in submerged, low-oxygen marine environments, but for visitors, the oil carries a more personal meaning. Many describe the droplets as “black tears.”

The Memorial and Its Rituals

In 1962, the USS Arizona Memorial was dedicated directly above the sunken hull. It is now part of the Pearl Harbor National Memorial, managed by the National Park Service, and draws roughly 1.8 million visitors per year. The white structure spans the midsection of the ship without touching it, and a marble wall inside lists the names of every crew member killed in the attack.

One of the memorial’s most distinctive traditions involves the Arizona’s surviving crew members. Any sailor who served aboard the ship during the attack could choose, upon death, to have his cremated remains placed inside the wreck. The interment ceremony is held at the memorial itself and includes a committal service, a rifle salute, the playing of Taps, a flag folding and presentation, and a plaque honoring the individual’s service. The urns are lowered by Navy divers into the well of Barbette No. 4, a gun turret foundation deep within the ship’s hull. In this way, survivors are reunited with the shipmates they lost decades earlier.

The last living Arizona survivor, Lou Conter, died peacefully at home in 2024 at the age of 102. With his passing, no one who served aboard the ship during the attack remains alive. Several dozen survivors chose interment aboard the Arizona over the years, and their plaques now line the memorial.

Why It Still Matters

The Arizona’s importance operates on several levels. Strategically, it represented the shock of a military disaster that destroyed a significant portion of the Pacific Fleet’s battleship strength in minutes. Politically, the concentrated loss of life aboard a single ship gave Americans a focal point for grief and anger that translated directly into wartime mobilization. Symbolically, because the ship was never raised, it became a permanent physical reminder in a way that rebuilt or scrapped vessels could not.

It also shaped how the United States commemorates military loss. The concept of leaving a warship in place as both a grave and a memorial was unusual in 1942 and remains rare today. The Arizona set a precedent for treating a disaster site not as wreckage to be cleared but as sacred ground, an approach later applied to other sites of national tragedy. The ship sitting quietly in Pearl Harbor, still leaking oil, still holding its crew, is what makes it different from a statue or a plaque. The memorial doesn’t represent the event. It is the event, preserved in place.
