The 20 ton Rotunda is designed to be a self sufficient combat platform and home for its single crew member.

From a distance, the sleek Rotunda resembles any number of civilian I.C.E. powered saloon cars, only enhanced by body kits which allow it to become a variety of other similarly shaped vehicle types. But under its mundane shell, a meager ton of Mercury Weave Ferro-Fibrous armor, the Rotunda is equipped for scouting and even light raiding duties. Unlike other scout vehicles, the Rotunda is built for maximum endurance while under cover, its LTV 160 Fusion Engine gives it effectively unlimited range, and the driver's cooking and sleeping accommodations, if cramped, mean they can operate away from base for over three months.[3][5][6]

While a popular vehicle, the Rotunda was one of many designs whose fate was sealed by the early Succession Wars. After the Dieron-based assembly lines of its manufacturer, Buhallin Military Products, were destroyed in 2776, the number of Rotundas dwindled due to a lack of spare parts and the dire need for Fusion Engines for BattleMechs and other Combat Vehicles. The design became extinct outside the stockpiled examples in the military forces of ComStar and the Word of Blake.[3][5][6]

Weapons and Equipment[edit]

While intended only as a scout and lightly armored, the Rotunda features a small but significant weapons array with which to defend itself or take out targets of opportunity. The primary weapon is Amdecker 300 Large Laser, back-up provided by a Holly SRM-2 rack with a single ton of reloads. While the Holly rack is one of the best known and trusted designs, the accurate Amdecker laser is not, with many drivers reporting issues with heat dissipation and technicians repairing it.[3][5][6]


  • J-100 
    An early variant, the 100 series lacked sturdy suspension system and needed frequent maintenance, limiting its endurance.
  • J-110 
    Fixed their suspension issues, but near identical armor placement as the 100.
  • LRM 
    This version of the Rotunda replaces the fusion engine with a traditional ICE version, which reduces the top speed slightly. It also replaces the standard weapons with a pair of LRM-5s and a single ton of ammunition. BV (2.0) = 303[7]
  • Rocket Launcher 
    This variant uses the same ICE engine as the LRM version, but replaces the standard weapon for five fifteen tube Rocket Launchers. BV (2.0) = 320[8]
  • SRM 
    This version uses the same engine, chassis, and armor as the LRM version, but mounts a quartet of SRM-2 launchers and a ton of ammunition in place of the standard weaponry.[9]
