I did mention when standing. The Macross class means it changes forms-- one's more of a ship type, the other is a humanoid shaped mecha. The left and right arms serve as flight decks for the fighter planes and pilots I talked about. They can also separate and serve as smaller ships if need be.

[Drink now gone, Kaname places the glass on the tray of a waitress passing by.]

The propulsion systems, the ships themselves, and the valkyries-- the planes, were all developed from technology reverse engineered from an alien ship that landed on Earth about seventy years ago. It was turned into the first Macross class.
