A massive fictional variable military Spacecraft from the Macross science fiction series.
The New U.N. Spacy "Macross Cannon Class" is a transformable Space fortress (and Mecha) from the anime Macross 2 released in the 90s.
The massive Macross Cannon vessels are heavily armed ships designed for intense anti-ship combat.
Over 6,000 meters (more than 6500 yards) long, this class of combat vessel is connected to four refurbished Nupetiet-Vergnitzs Zentradi battleships.
Each ship is armed with one heavy converging energy beam "SDF-1 Macross-style" cannon that opens along the horizontal axis to collimate the heavy converging energy beams for use against enemy warships.
The Macross Cannon ships with their 4 heavy particle cannons are extremely effective vessels for countering massive enemy fleets of warships and their multiple heavy guns allow a single Macross Cannon to destroy multiple ships with one volley.
In real life the ship was designed by mecha anime designer Oohata Kouichi in the early 90s.
