Technology & Combat Characteristics
The Prototype Stark Jegan is created by making drastic modifications to the original RGM-89 Jegan, and is meant for anti-ship combat. A small number were produced as functional testbeds for the RGM-89D Jegan D Type based RGM-89S Stark Jegan. Like the Stark Jegan, the Prototype Stark Jegan is fitted with additional leg armor and thrusters that can be ejected if needed. Among the differences between the prototype version and the standard model is that the prototype model is not as heavily armored. However, some of its body armor uses Gundarium Alloy making it more resistant to enemies projectiles. Secondly, the missiles used by the two units differ, with the prototype model capable of mounting four large anti-ship missiles. Lastly, the prototype model has a protruding chest due to it being a two-seater, while the standard model reverts to needing only one pilot.
History
The RGM-89S Prototype Stark Jegan was one of the mobile suits supplied to the Londo Bell ship SCVA-76 Nahel Argama as part of the ship's reinforcements. It was then deployed alongside a few Stark Jegans, using their missiles to bombard the Sleeves' asteroid base Palau, before engaging the enemy's mobile suits with other allied units. Sometime later, during the Battle of Industrial 7, the final battle of the Laplace Incident, the Prototype Stark Jegan was one of the mobile suits launched from the Nahel Argama to fend off the Sleeves' mobile suits. Unfortunately, it was bisected by a beam shot from a AMX-008 Ga-Zowmn and destroyed.
