The ADR-04 Defender , commonly referred to simply as the Defender, was a mass-produced air defense destroid of the Robotech Defense Force (RDF) and Task Force Southern Cross before being mothballed for smaller, more compact mecha. It was first seen in Robotech: The Macross Saga.

DevelopmentEdit

The ADR-04 Defender series was one of three Destroids that have a Viggers Industries leg assembly in common. This was a design requirement so as to keep development costs down. While the other Earth-designed Destroid in this series, the MBR-04 Tomahawk, is a main battle robot, the ADR-04 was an air defense robot, intended to either guard important rear area installations, or, by using its comparable mobility, to join the Main Battle Robots on deployments. In the latter cases, the Defender also served as a satisfactory fire support platform, although the armament was unsuited for indirect fire.

Technology and Combat CharacteristicsEdit

Catering to its specialization (close and medium range air defense), the Defender was equipped with a powerful radar system and advanced targeting computer, and with broadband ESM equipment for battle situations in which active radar emissions would not be wise. The system lay-out and integration delivered a fine, capable mecha, but the design process was protracted and expensive, with no less than 9 different versions and prototypes being built (occasionally in parallel) until the production version took shape in late 2008.

As an anti-aircraft mecha, the Defender did a magnificent job, with its extremely effective hypervelocity guns. These relatively large-caliber weapons had a very high muzzle velocity, and thus short flight times and great kinetic energy penetration capabilities, making the shells quite effective against airborne mecha. In addition, the rounds were terminally guided by the mecha, using a semi-active laser designator system. Other mecha could also provide terminal guidance, as the standard laser ranger/designator was used, but only if they were in full datalink with the firing Defender.

The Destroids based on this undercarriage were among the most important mecha during the First Robotech War and the later Malcontent Uprisings through 2016. Numerous Defenders lumbered on in local militias until 2019, and many can still be seen in museums today.

ArmorEdit

The armor on the Defender 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 Defender provided full protection from nuclear, biological, and chemical hazards, using a sealed cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies could provide atmosphere for three days maximum.
