This is a kit of the mother ship, Arcadia flown by the space pirate, Captain Harlock from the adventure filled world of Leiji Matsumoto. Originally created in 1977 for a manga TV series, Captain Harlock has appeared in various film and TV shows, most recently a 2013 feature film, "Space Pirate Captain Harlock". This space battleship is used for his interspace travel. The Arcadia carries a number of Space Wolf fighter planes for protection and offense.
The Arcadia is equipped with heavy firepower. The main armament consists of triple-mount pulsar cannon turrets, two on the upper deck and one on the underside. When Captain Harlock's friend, Tochiro, designed the Arcadia, he must have been influenced by pirate ships of old, because the rear of the Arcadia resembles the stern of a Spanish Galleon. I am not sure of the significance of this but it looks neat.
