First Great War
Fight with Bloodbergian Navy I guess or maybe Kadolhan

Second Great War
The All-Kusian Navy, previously Kusian Imperial Navy, had major participation in the Second Great War in providing convoy support and raiding, and blockade of access for Kadolhan Navy near south Sremian dependant territory. For the majority of the conflict, Kusian and Kadolhan navies were standing prepared for a standoff, blockading each other's efforts from proceeding towards each other allied territory. Kusian and Sremian navies had an incident. Sremian naval force engaged onto Kusian forces in Southern Púŕeoćús region due to successful misinformation operation conducted by Bloodian forces in Sremia, causing Sremian authorities in northern Sremia to believe that Kusian forces have betrayed them and sided with the enemy, causing a land-air-sea Battle of Lost Coastline which lasted from March 10th to 14th 1944, causing major damage to Sremian Coast Guard ships and destruction of Kusian military base and tank school of Lost Coastline. It was the first engagement of then unfinished first Kusian supercarrier. Kusian naval forces took huge casualties over duration of the raiding campaign of Bloodian convoys trying to prevent transportation of goods and vehicles from Bloodia's new world territories, causing a complete collapse and halt of All-Kusian Navy by 1945.

Cold War
After the Second Great War, All-Kusian Navy was devestated and the only major surface fleet ships that were in operating condition were the latest built designs that did not leave the Kusian waters to participate in Bloodian convoy raiding, after multiple years of debates, Kusian populus voted on not restoring the expeditionary naval fleet and instead focus on the defense of Kusian territorial waters, which lead to the decree of disbanding of the All-Kusian Navy on 27th of October 1953. During the Cold War, All-Kusian Navy went through drastic upgrade and scrapping of older classes of ships with massive adoption of radar technologies and missile armament. First battle test of the new technologies was in Dongkuo, while conducting the Special Operation in Dongkuo with extensive usage of naval aviation and providing support for allied troops on land as well as artillery support off the shore. Special Operation in Dongkuo showed the massive amount of issues with newly adopted systems, causing massive downtimes of the ships and lack of activity abroad.

Fleet Aviation
The Kusian Fleet Aviation is a branch of Kusian Coast guard that's in command of shore and naval borne aircraft that are tasked with combat and logistical support, as well as rescuing and recconisance duties.
