Battle of the Philippine Sea
Major naval battle of World War II

The Battle of the Philippine Sea was a major naval battle of World War II on 19–20 June 1944 that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious reconquest of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. The battle was the largest carrier-to-carrier engagement in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft.

Why this record matters
“Battle of the Philippine Sea” is worth following because a concise public description often conceals a longer documentary argument. Here, Battle, Philippine and Major provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 17, 2026. The first chronological checks are 1944.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
