The SDR-04 Phalanx, commonly referred to as the Phalanx, was an air defense destroid of the Robotech Defense Force (RDF) and later, Task Force Southern Cross before being mothballed for smaller, more compact battloids. It was first featured in the series Robotech: The Macross Saga.


The SDR-04 Phalanx missile launch battery was part of the main Destroid series used during the First Robotech War. This Destroid was designed to provide more mobility to the tactical missile launchers previously in use on Earth. This Destroid used the same leg assembly as the MBR-04 Tomahawk heavy infantry mecha and ADR-04 Defender air defense mecha.

Technology and Combat CharacteristicsEdit

A missile-launching mecha was needed because of the vulnerability of fixed missile batteries. Therefore, the Phalanx torso was designed. It consisted out of nothing more than a missile-launch station and pilot seat, data-link equipment and two very large missile pods. These missile pods could carry 22 of the largest mecha-mounted each, which gave one Phalanx firepower comparable to the refitted Iowa-class battleships in service with the 1980s US Navy. The Phalanx usually fired its long range missiles from a position 20-100km away from the fighting, because this mecha had very little in the way of secondary armament and really only minimal armor. It could fire its missiles on a direct trajectory, but this would degrade its stand-off capabilities by using large LR missiles for what was essentially SR work. The Phalanx was developed on the Super Dimension Fortress-1 Macross (SDF-1) in late 2009, and did not see service on Earth until after the Zentraedi Holocaust. A variant, the Mark XIII, saw service with the RDF Army, and incorporated a pair of miniguns for emergency anti-personnel use.

The Destroids based on this undercarriage were among the most important mecha during the First Robotech War and the later Malcontent Uprisings.


The armor on the Phalanx was composed of a standard Chobham laminar developed in the late 20th century and improved with the materials science advances made during the Robotech era. This armor was mainly designed to defeat projectiles and other kinetic weapons. The armor stopped all small arms and heavy infantry weapons fire, provided excellent resistance to light mecha-mounted weaponry, such as the Zentraedi 22.3mm HE autocannon round, and fair resistance to medium mecha-mounted weaponry, such as the Valkyrie's 55mm APFSDS round.

The Phalanx provided full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies provided atmosphere for three days maximum.
