The Destroid Defender (official designation ADR-04-Mk X), also known as the Raidar X, was a Destroid fielded by the United Earth forces during the First Robotech War. The Defender was based on the Destroid Tomahawk chassis. Its main armaments were two twin long-range 78mm anti-aircraft guns. It carried an extensive radar suite, which allowed the Defender to engage hostile forces at long ranges. It was capable of limited space operations due to its vernier thrusters. (Robotech Infopedia)
