Operation Flicker

Operation Flicker or the Battle of the Galapagos Islands was an engagement off the coast of the Galapagos Islands that involved the PACODO carrier forces in a three way battle against the Indochinese Expeditionary Fleet and the South American Pacific Fleet in what is commonly agreed upon to be the largest naval battle in history. Involving more aircraft carriers and aircraft than the Battle of the Philippine Sea, it also holds the distinction of being the largest carrier battle in history. Fought between the early morning of 2 December 2019 to the afternoon of 4 December, the coalition aimed to destroy the bulk of the naval forces of both the Indochinese Federation and the South American Federation in a single battle.

By the end of the battle, both the South American Navy and the Indochinese Navy had fewer escort vessels than PACODO had aircraft carriers. During the battle, the South American Navy attempted to reinforce their fleet in the early morning of 3 December, however the reinforcement fleet was caught and destroyed by Southern Union, New English, and Yuktobanian naval forces. There was no attempt by the Indochinese Navy to relieve their naval force due to the start of Operation Tropic Freedom in Asia.

The battle consisted of five main separate engagements that occurred on different days: the Battle of Coordinate Yosu (early 2 December), the Battle of Coordinate Asar (afternoon 2 December), the Battle of Coordinate Ina (early 3 December), Battle off Santa Cruz (afternoon 3 December) and the Battle of Coordinate Ansen (afternoon 4 December), as well as lesser actions such as the Bombardment of Santa Cruz (afternoon 4 December).

Commonly touted as the "most expensive battle in history", the South American Navy and Indochinese Navy lost more assets during Operation Flicker than the rest of the war combined. After the battle, the South American Navy's Pacific Fleet was effectively destroyed, and with continuing naval engagements in the Atlantic Ocean, the South American Navy as a whole was helpless to stop Operation Caligula, which kicked off roughly a month later.
