Operation Flyhook

The Small Cronan Sea War, officially Operation Flyhook or amongst Arcer submariners 'The Capetian Vacation,' was a period during the Second Great War during which Arcer submarines and their allies attacked Capetian merchant shipping and naval surface vessels along the Capetian Peninsula and in the Polynesian Sea. The engagement lasted the duration of the Second Great War, with several distinct phases occuring due to technological advancements or fluctuations in the course of the war's fighting.

The campaign lasted nine years, with the first engagements by Arcer submarines beginning just a few short weeks after the war's announcement, as it was part of Operation Forefront, the larger Arcer naval campaign in South Crona, the Songun and Polynesian Seas. Weak and disparate Capetian leadership early in the campaign meant that triple-digit losses were recorded of Capetian shipping with a number of notable surface vessels sunk.

Due to the lack of direct engagement by Arcer surface vessels against their Capetian counterparts, this portion of the conflict is considered the most dynamic and directly involved portion of the war on the naval side, as the Army and Air Force were embattled under Operation Lightfoot with their Paulastran allies.
