The Space Defense Robot (SDR) Phalanx Mk XII was the final destroid designed during Space War I to act as a fleet defense mecha. After the space worthy conversion of the CVS-101 Prometheus and the SLV-111 Daedalus carriers they were docked with the SDF-1 Macross and required a special unit mecha to defend both vessels. Development of the Phalanx began during the war in July 2009 and quickly reached rollout in December of that year. Roughly 20 Phalanx destroids were built aboard the SDF-1 Macross shipboard factories. Armed with dozens of missiles in two large launchers, the Phalanx made an excellent semi-mobile missile-based battery (minor variants featured armaments such as a head-mounted gatling gun). During the final battle of Space War I against the Zentradi Bodol Zer Main Fleet, the Phalanx units were repainted and refitted to fire long-range reaction warheads for use against space warships. When the SDF-1 Macross broke through the Zentradi fleet defenses and entered the interior of the massive Fulbtzs Berrentzs command vessel, all the Phalanx units unleashed their missiles and aided in the swift destruction of the enemy flagship.
