U.S. Navy intelligence decoded intercepted Japanese transmissions revealing Admiral Yamamoto's travel itinerary through the Solomon Islands. American leaders, blaming Yamamoto for the Pearl Harbor attack, authorized a targeted mission to kill him as an act of strategic revenge and to disrupt Japanese naval command.
On 18 April 1943, U.S. Army Air Forces P-38 fighters flying from Kukum Field on Guadalcanal intercepted Yamamoto's flight near Bougainville Island during the Solomon Islands campaign. His G4M1 transport aircraft was shot down, killing the commander of Japan's Combined Fleet.
Yamamoto's death damaged Japanese naval morale and elevated Allied confidence. A dispute arose over which American pilot deserved credit for the kill, with most modern historians crediting Rex T. Barber. The operation demonstrated that decrypted intelligence could be used to execute high-value targeted killings.
