The Frankfurt am Main (Frankfurt class) was the first modern airship built by the German Air Navy, which has been promoting the modernization of airships.
Although its armament is somewhat outdated, it has the latest radar system and hull design, and its jet-reciprocating composite propulsion system makes it faster than current airships can keep up with.
However, the ship's ability to turn at high speeds has been sacrificed, and it is recommended that when turning, the ship should slow down and then quickly turn under cover of the clouds.
The ship's hull design is also quite small for a patrol ship, so there is almost no space inside the ship, and only one main gun turret is equipped. Although other armaments were not installed, the ship is currently in advanced mass production, so it is possible to add main and secondary guns with a few design changes.
Incidentally, it is called “whale” or “cloud whale” by the enemy and “sky whale” by the people because it looks like a whale when looked up from above or below.
