Eagle has been researching unmanned submersibles for quite some time now, with technology far more advanced than any other place.
Normally, these submersibles are responsible for detecting various hydrographic data and mapping out the local riverbeds to prepare for submarines' entry. After all, a submarine must be familiar with the local terrain and hydrographic data for better concealment.
Unmanned submersibles can also perform reconnaissance and counter-reconnaissance tasks, capable of a wide range of functions.
They fear neither the harsh hydrologic conditions nor the extreme dangers of the seafloor, able to conduct long-term and high-level intelligence gathering underwater, rightfully called the 'Undersea Reconnaissance Soldiers' of future warfare.
However, when developing unmanned submersibles, several common problems are encountered, such as long-lasting battery technology, command and control technological barriers, and complex recovery processes.
