The Battle Frontier (abbreviated name, Battle 25) is a N.U.N.S. variable stealth space attack aircraft carrier connected at the tip of Island 1 and charged with guarding the Macross Frontier colony convoy.
Much larger than the Macross 7 Class, the Battle 25 was designed for enhanced fighting strength and command abilities to accomodate the much larger scale of the emigrant fleet and the accompanying naval fleet. These changes resulted in the Battle 25 being built over 200 meters longer than the Battle 7 class (Battle 25 length: 1,681 meters) and the operational weight was doubled to 16,550,000 metric tons.
The Battle Frontier is formed by six ships: two stealth medium space carriers (which function as the arms in attack mode), one Combat Command Carrier ("central block"), two medium assault battleships (functioning as the leg "engine blocks"") and one heavy bombardment warship ("Gunship").
When separated, each ship is fold capable, combat capable and otherwise possesses all capabilities of a space battleship. Although Battle Frontier and Battle Galaxy are the same type of warship with a common design they differ greatly in interior design and electronic equipment.
