The Alliance Challenger is a medium-sized combat spacecraft designed with a sleek, aerodynamic profile, featuring angular and aggressive lines that emphasize its combat-ready nature. Its hull is constructed from advanced metallic alloys with a matte finish, accented by glowing blue engine exhausts and weapon hardpoints that hint at its high-energy systems. The ship's surface includes panel lines and recessed areas for heat dissipation, with occasional wear and tear marks to suggest its veteran status in battle.
