Gosu (A, B) (Royal Command Battloid, Invid Battloid)
|Breadth :||4.4 m|
|Weight:||24.2 metric tons|
The armor of the Gosu is composed of a composite of metals, ceramics, and organics unique to Invid manufacture. Research continues into the composition of this material, though results from X-ray crystallography, NMR, and mass spectroscopy studies remain classified. The armor stops all small arms, heavy infantry weapons fire, and light mecha-mounted weaponry, and provides fair to good resistance to medium mecha-mounted weaponry, such as the Valkyrie's 55mm APFSDS round. Like on the Gamo, much of the armor is sloped or rounded, giving almost perfect performance against the standard human 35mm shells fired from so many mecha and craft. Only shells of this size that impact at shallow angles to the armor have a chance of penetrating. The armor on the forearms is substantially superior, and stops all small arms, heavy infantry weapons fire, and light mecha-mounted weaponry, and provides good to excellent resistance to medium mecha-mounted weaponry, such as the Valkyrie's 55mm APFSDS round, and poor to fair resistance to heavy mecha-mounted weaponry, such as the VHT-2's 120mm smoothbore shells.
All Invid mecha provide full protection from nuclear, biological, and chemical hazards, using a sealed overpressure cockpit environment.
The Gosu was first seen in conjunction with the humanoid Invid, and it is therefore often assumed that the Gosu battloid was designed for the Solugi Invid exclusively. This is, however, incorrect. The Solugi themselves have indicated that the decision over their physical form was not made until 2043, but the Gosu, to come into service at that moment, must have been in development for several years beforehand.
Numerous Invid sources place the genesis of the Gosu design around 2038, and although this has not been officially confirmed, it has never been contradicted either. After an examination of mecha effectiveness, including the Bioroids, Battlepods and recently encountered Alpha fighters, they found that the most effective of these enemy mecha had heavy missile batteries and extremely high maneuverability near the ground, where almost all battles were decided. Speed, especially in the high Mach numbers, was important only in dedicated fighters. In the case of Earth mecha, all this and high speed was achieved by the transformable nature of the mecha; in the case of the Zentraedi Quaedluun-Rau Power Armor, the sheer bulk could accommodate the huge engines necessary for heavy accelerations and an unprecedented 126 dogfight missiles. Eventually the Invid came up with a non-transformable design that combined the best of the features with the least amount of compromise. The new mecha, the Gosu, like all other Invid mecha, uses a cockpit system not unlike that of the Tirolian Bioroid, although the Invid versions do allow for movement in the cockpit. In addition, and again unlike previous mecha, the Gosu is humanoid in appearance.
The Gosu is about the size of an Alpha fighter, but the combined thruster/missile launcher design is more reminiscent of the Quaedluun-Rau Power Armor than of any Veritech design features. While it is natural to assume the humanoid shape was dictated by the shape of its first pilots, this is untrue, as that decision was made for aerodynamical reason, as in level, high speed flight, a humanoid frame is more streamlined than the custumary crab-like modelling of earlier Invid mecha.
The huge engines in the back propel the Gosu at speeds up to 1160 kph. This means that the Gosu cannot go supersonic. The Invid, however, do not see this as a design flaw since most of their airborne warfare is fought at speeds between speeds of 20 kph (ground attack) and 1000 kph (aerial combat). The high speeds of the Terran Veritech mecha were not needed for the Gosu, since they were intended as command and ground attack mecha. Also, because of their large numbers, there is usually an Invid unit in range of a high speed hostile, where humans and Zentraedi, with their somewhat lower preferred density, would need faster mecha to cover equal amounts of ground in equal amounts of time. A such the Invid lack a dedicated high-speed atmosphere capable fighter, and rely on numbers to deal with fast, airborne, foes, although present trends in mecha design lean to more capable weapon systems (mainly missiles) to engage fast movers, and likely a true aerial mecha is being studied.
The weapons for the Gosu are more diverse than on other Invid mecha. Where the Iigaa and the Gurab carry two cannons each, and the Gamo has two cannons with two small secondaries, the Gosu has one (albeit large and multi-functional) plasma cannon, but also a secondary laser in its head (copied from the human Valkyrie and AGACs mecha, but hidden in the manner of the forearm cannons on the Invid Malar), and a large number of anti-mecha missiles in the thruster housings. This is the first time that missiles have appeared on an Invid mecha. They provide the Gosu with a very powerful punch, and the design is exceeded in number of missiles carried only by the Quaedluun-Rau Power Armor. Two types of missiles are carried: a short-ranged dogfighting missile for use against slow-moving mecha, and a longer-ranged and faster missile used against faster targets. Combined, these weapons give the Gosu a capability at all ranges that is totally new for Invid designs. Invid experience with missile tactics was minimal in the Third Robotech War, and the Invid pilots seemed to rely almost exclusively on their cannons, using missiles almost solely as an afterthought. This could, however, indicate a lack of confidence in the missiles on the part of the pilots; certainly, only a few of the missiles reached their intended targets, most being decoyed by their targets' electronic warfare system, simply being outflown, or prematurely detonated. Likely this was due to the fact that the Invid were new to missile technologies.
Since the end of the Third Robotech War, the Solugi remaining on Earth have produced large numbers of Gosu mecha for their militia. An improved version is now being produced, the Gosu-B, and many of the Gosu-A are being refitted to the new standard. The main differences are a more capable weapon system, including anti-radiation missiles, and a Jehudi-type active visual low-observability system. Human tacticians have suggested that the anti-radiation missiles will make it difficult for stealth fighters to activate their radars, and the optical cloaking system will further draw human mecha into Invid range, thus effectively negating the present human stealth and range advantage.
