航空宇宙自衛隊大型宇宙警備艇「みかづき」
The Futsutsuki is of the same type. The name "FUTSUZUKI" was chosen as a "security boat" because it is not a combat ship, although the name "destroyer" is used to refer to the Maritime Self-Defense Force (MASDF). Internationally, it is called Space Destroyer. The Maritime Self-Defense Force has yet to deploy its own nuclear-powered submarines, and is not on the best of terms with the Air Self-Defense Force.
The visual surveillance compartment has become a standard feature of the Aerospace Self-Defense Force's space ships, based on its operational experience with the Yuyake-class missile ship (see illust/96150383 ). It is not a combat bridge, but a place for the crew to look out, relax, and check the status of targets in the field of view. Some of the living quarters are located here because the bridge, which extends outward by rotating the ship (the common name, not the official name), can generate a stronger and more stable artificial gravity than the inside of the ship. Some Indian and British ships are also equipped with such "bridges," but they are not common because they are structurally weak points, and at the same time, they reduce propulsion efficiency by shifting the center of gravity. It is a mystery why the Japanese insist so much on installing a bridge on their spacecraft.
On a different note, Space Battleship Yamato is still cool.
