The MAS-2xB represented a mobile form of blaster artillery and a siege-oriented weapon system. It was the product of Loronar Defense Industries. This weapon took the form of a substantial, ovoid platform housing a turbolaser, and it was designed specifically for the armed forces of the New Republic.
The MAS-2xB's shape was ovoid, featuring a compact command module situated below the main body of the vehicle. Due to its immense weight, the weapon relied on a system of seven repulsorlift units for propulsion. The vehicle's acceleration was notably slow, and its maneuverability was practically nonexistent. The MAS-2xB had a maximum operational altitude of fifty meters, and its top speed was limited to forty-five kilometers per hour. In terms of size, the MAS-2xB was twice the size of an AT-AT walker.
Operating the weapon required a crew of fifteen soldiers, which included six technicians and engineers. These personnel were responsible for maintaining the Republic Engineering Corporation 4.2FC fusion power core and the repulsorlift drive systems, as they were prone to frequent power fluctuations and mechanical failures. To mitigate the risk of power overloads, the MAS-2xB was equipped with sixteen energy dampers, with approximately half of them requiring replacement after combat engagements. Specialized docking platforms were also necessary to facilitate the maintenance and repair of MAS-2xB units.
The primary offensive weapon of the MAS-2xB was a mounted turbolaser pulsor. This weapon was capable of breaching even the most sophisticated and advanced defensive systems. These vehicles could also be deployed against military emplacements, troop concentrations, transportation hubs, and even capital ships positioned in low orbit. The MAS-2xB derived its power from a substantial Republic Engineering Corporation 4.2FC fusion power core.
The turbolaser pulsor utilized an amplification dish positioned around the turbolaser actuator to concentrate its energy beam. This beam had an effective range of ten to thirty kilometers and could penetrate nearly twenty meters of durasteel. The pulsor's energy output was comparable to that of a Star Destroyer's turbolasers. However, due to its high power consumption, the pulsor could only be fired once per minute. The firing of the pulsor also generated an extremely loud roar. To prevent critical system failures during combat, the power core, energy capacitors, and the pulsor were surrounded by four rows of cooling chambers filled with cryogenic cylinders.
For defense against enemy vehicles, the MAS-2xB was equipped with two twin-turbolaser turrets and a quad heavy laser cannon mounted on the command module. The vehicle was protected by armor plating with a thickness of two meters, as well as six shield generators.
The MAS-2xB was developed from earlier turbolaser-based weaponry, including the Speizoc Arms C-136 "Grandfather Gun" and Loronar's Turbolaser System I. This mobile platform, equipped with a turbolaser, was specifically designed for utilization by the New Republic's military forces. The cost of a single unit approached one million credits. Consequently, the New Republic maintained a relatively small number of these vehicles, deploying them only in strategically significant engagements.
