宇宙戦艦 アンドロメダ 級 アクエリアスKOTOBASHI MAKOTO SPACE BATTLESHIP ANDROMEDA CLASS AQUARIUS

  This is a model by 小林誠 2202 (not the manga artist) Basically , it is a combination of Ginga and Andromeda, but I like this better than the red-and-bluish-gray Andromeda DX!

 I think the ship has enough space at the back to preserve the fourth beam cannon which is removed due to the size of the bridge tower.
