Army of the Southern Cross

The SRB-9 Satyr was a mass-produced combat engineering battloid of the Army of the Southern Cross, and it was part of Robotech: The Masters.


The SRB-9 Satyr, commonly known by it's nickname "Billy Goat", at first seems to mirror the CBL-8 Dryad's mission and capabilities. But where as the Dryad was originally a non-military construction robot, the Satyr was devised by the Proteus Group as an armored, jump capable, combat engineering robot from the get go. The Dryad was optimized for jungle and marshy environments, the Satyr on the other hand was meant to be used to reclaim terrain-embedded Zentraedi warships, to help construct defensive emplacements in mountainous terrain and to provide mobile hardened command, control, communications, and intelligence relay stations for mountain-based infantry.

After the Zentraedi Holocaust and the following years of unrest and uncertainty, many communities desired more protective locations in out of the way locations, such as canyons and blast craters. As such, the Satyr was expected to assist in building these communities, when their duties didn't keep them occupied elsewhere. With its powerful winches, the Satyros was also used as an armored recovery vehicle and in maintenance areas to lift heavy equipment.

Due to the poor radio propagation environment of mountainous terrain, the Satyr assisted the Alpine forces of the Tactical Corps in maintaining communications between their units. This battloid was equipped with a powerful communications relay capability, which could be boosted by the addition of high gain whip antennas. It was also equipped with a powerful radar set for a non-combat battloid that was evidenced by the twin arrays located to either side of the head.

Technology and Combat CharacteristicsEdit

The Mk. I was an unarmed military construction/salvage/mining robot for use in the mountains. With Task Force Southern Cross beginning as a unified command of the Robotech Defense Force (RDF) units in South America, they quickly discovered the vulnerability of this mecha in a combat situation without built-in weapon systems. Therefore, the Southern Cross Army Robotech Research Department (SCAR) devised an armed refit for this battloid to assist in mountainous combat arenas like the Andes mountains. After years of use of the Mk. I, the Southern Cross designed a newer version optimized for its combat role as well as keeping its engineering capabilities to support the Southern Cross in mountainous terrain, designated the Mk. II. The refit consisted of the addition of a MRL-15 missile launcher containing 15 Hammerhead missiles, which were one of the most common (and capable) missiles in the ASC's inventory. It also added a laser range finder/designator, which was conspicuously missing up to that point.

Visually, the Satyr was a very distinctive mecha. With it's large shoulders, clawed arms and hands and long skinny legs it looked very close to it's Greek namesake. The feet were long and thin, giving them the agility needed for mountaineering. It also had mounting points on the feet for adding spikes to assist in climbing. The arms could mount either a claw or a grappling hook (usually one of each). It also provided accessories to support an infantry team. Knee rings for mounting ropes and a chest bar for rigging off of. The Satyr had wrist spikes to assist it in climbing as well as fully rotating shoulder and upper arm joints. It was also limited-flight-capable, which proved a life saver any time a pilot found himself involuntarily airborne.


The armor on the Satyr was a new development in low-mass composite-materials Chobham plating that became the standard for all Terran mecha. Aside from the respectable protection provided against projectiles, missiles, and other kinetic weapons, this armor is also resistant to plasma globes (annihilation discs), lasers, and to a lesser extent, particle guns, owing to the fact that the armor can flake off and evaporate in layers under fire from such high-energy weapons, taking much of the weapon's energy and converting it into the latent heat of sublimation in the armor. The armor stopped all small arms and heavy infantry weapons fire, provides 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 VF-1 Valkyrie's 55mm APFSDS round.

The Satyr provided full protection from nuclear, biological, and chemical hazards, using a fully sealed cockpit modual activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The module was also armored and gives the Satyr the option of operating off-planet on the Moon or elsewhere in the system. The internal consumables supplies could provide atmosphere purification for one week maximum on Earth and 48 hours in a hostile environment such as the Moon or Mars.


With the outbreak of the Malcontent Uprisings, Task Force Southern Cross began requesting mecha to fulfill numerous operations in specialized environments. With the successful deployment of the Dryad battloid, the Southern Cross turned next to the Satyr Mountain Combat/Engineering Robot. Where the Dryad was meant to operate under the thick canopy of the Amazon Basin, the Satyr was designed for the high altitude of the Andes Mountains. Numerous Zentraedi groups hid among the local populations and scavenged weapons and supplies from downed their cruisers.

The main strategy of defeating the renegade forces was first to deny them the materiel needed to wage Robotech level guerilla warfare. In order to get inside many of these wrecks, dedicated teams of mountain climbers had to risk their lives. In order to give these teams a modest chance the Satyr was ordered.

At the end of the Malcontent Uprisings, most of the Satyrs remained in the mountains of South America where the Alpine Divisions were usually based (nicknamed the Mountain Offensive Squad). Like the Dryad, Salamander and Fenris, a number of Satyrs and their trained crews accompanied the Pioneer Mission as special operation units.

During the Second Robotech War, they acted as combat engineers and as infantry support battloids. Later, after the Invid Invasion, they served in a limited capacity with freedom fighters where their role in the fighting was not relegated to the mountains. No complete, functional models were known to exist since then.
