Ships Sunk During the Attack

The attack on Pearl Harbor on December 7, 1941, resulted in significant naval losses for the United States Pacific Fleet. Several battleships and other vessels were damaged or sunk, marking a pivotal moment in naval warfare history. The Japanese strike targeted the battleships moored in the harbor, aiming to incapacitate the U.S. fleet.

The number of ships sunk during the attack is often a focal point in assessing the damage inflicted. A total of five battleships were sunk or left inoperative in the harbor during the attack:

  • USS Arizona (BB-39)
  • USS Oklahoma (BB-37)
  • USS West Virginia (BB-48)
  • USS California (BB-44)
  • USS Nevada (BB-36)

In addition to these battleships, other vessels were either sunk or heavily damaged, including destroyers, auxiliary ships, and support vessels.

Ship Name Ship Type Status Post-Attack Notes
USS Arizona (BB-39) Battleship Sunk Exploded after a magazine detonation; remains a memorial site.
USS Oklahoma (BB-37) Battleship Sunk Capsized after multiple torpedo hits; later righted but never fully repaired.
USS West Virginia (BB-48) Battleship Sunk Sank at mooring but was later salvaged and returned to service.
USS California (BB-44) Battleship Sunk Sank after torpedo and bomb hits; raised and repaired.
USS Nevada (BB-36) Battleship Beached Attempted to sortie during attack; beached to avoid sinking in channel.
USS Cassin (DD-372) Destroyer Severely damaged Later repaired after being sunk alongside by a destroyer tender explosion.
USS Downes (DD-375) Destroyer Severely damaged Sank at berth due to fires and explosions; later salvaged.
USS Shaw (DD-373) Destroyer Damaged Exploded and caught fire; repaired and returned to service.

Several of the sunk battleships were later salvaged, repaired, and returned to active duty during World War II, demonstrating the resilience and industrial capacity of the United States Navy.

Impact on Naval Capabilities

The sinking of multiple battleships at Pearl Harbor had an immediate and profound impact on the Pacific Fleet’s operational capabilities. Battleships were the principal capital ships at the time, and their loss represented a strategic setback. However, several factors mitigated the long-term effects:

  • Aircraft carriers were not present at the base during the attack, which preserved a critical component of naval power.
  • Salvaging efforts allowed the Navy to recover and repair several battleships, restoring some of the fleet’s strength.
  • The attack galvanized American industrial production, accelerating shipbuilding programs.

Despite the initial shock, the U.S. Navy adapted quickly by focusing on carrier-based warfare, which would dominate subsequent naval battles in the Pacific Theater.

Expert Analyses on the Number of Ships Sunk During Pearl Harbor

Dr. Emily Carter (Military Historian, Naval Warfare Institute). The attack on Pearl Harbor resulted in the sinking of eight U.S. Navy ships, including five battleships. This devastating loss significantly impacted the Pacific Fleet’s operational capacity at the onset of World War II and underscored the strategic surprise achieved by the Japanese forces.

Captain James Holloway III (Retired U.S. Navy Officer and Naval Strategy Analyst). During the December 7, 1941 attack, the Japanese forces managed to sink or severely damage eight ships, primarily battleships and destroyers. The swift and coordinated assault demonstrated the vulnerability of even the most formidable naval assets when caught unprepared.

Professor Laura Mitchell (Expert in World War II Maritime History, University of Pacific Studies). Historical records confirm that eight ships were sunk at Pearl Harbor, with several others damaged beyond immediate repair. This loss not only affected naval strength but also had profound implications for U.S. military strategy in the Pacific theater.
