Mobile Suit Gundam SEED MSV Astray

A mysterious abandoned alien spaceship crashes to Earth, offering an unknown and mysterious technology known as Robotech. Humanity unites to rebuild the spaceship, but on the day of its unveiling the rebuilt ship, now renamed the SDF-1, and the rest of the planet are attacked by an unknown alien race of giants called the Zentradi. In the first attack both military and civilians are forced to flee into deep space. The young Rick Hunter, who gets accidentally sucked into the war visiting his friend Lieutenant Fokker on the day of the attack, is faced with some difficult choices. As an ace pilot he could help out defending their new space-based home, or should he instead wait it out on the sidelines? If that isn't enough he also has to deal with his love for the mesmerizing Lynn Minmay, a young girl also pulled against her wishes into the conflict.
