Description/Overview:
 (MBR-01A1 "Avenger-II")
         The idea behind the MBR-01A1 was to build a battle robot capable of replacing both the MBR-01 and the MBR-01A. The MBR-01A had fought admirably during the first few campaigns of the 1st Interplanetary War, but the Earth sphere liberation and Venus campaigns had pushed the design to its limits and the EFF high command demanded a more powerful unit for the planetary invasion of Mars. Of particular concern was the presence of Type-75 Heavy Arthropod Tanks and SF-03 space fighters on Mars due to their long-range weapons capability that had cost the EFSM many MBR-01s and MBR-01As during the invasion of Venus. The recommendations by the Earth Federal Forces high command for a new battle robot were simply dismissed by the Eudaemonist-controlled senate and new President-Elect Beatrice Luxemburg. The EFF would have to make do with what they had if the Eudaemonists got their way. However, the EFSN and EFSM secretly convinced Rockwheel to design a new upgraded version of the MBR-01 at their Gundhim facility at the EFSN base on Juno. This new design was simply a MBR-01A upgraded with newer and more advanced systems.
         The MBR-01A1 uses one Federal Energy FEFR-300A improved fusion reactor as its main power supply. This reactor is nothing more than an upgraded version of the original reactor used in the MBR-01.
         The armaments of the MBR-01A1 were nearly identical to that of the MBR-01A, except for the addition of a long range missile launcher: one Norking SRM-03S space torpedo launcher. This weapon fired high speed space torpedoes capable of intercepting any type of atmospheric jet fighter or other aircraft. The range of the missile was such that the MBR-01A1 was able to fire the weapon before most types of UN vehicles could counterattack.
         Rockwheel-Gundhim also replaced the MBR-01A ‘backpack’ nuclear rocket system with a new, more advanced six engine cluster type. This new ‘rocket-pack’ used six Rockwheel TNRE-01 nuclear rocket engines. This six engine cluster was capable of propelling the MBR-01A1 at speed of 600 mp6h for up to eleven and a half hours before refueling. This engine cluster allowed the MBR-01A1 to fly in any environment, though its speed in an atmosphere was reduced to a maximum of 200 mph and an altitude of 1000 feet due to drag effects on the battle robot’s bulky frame.
         The electronic systems of the MBR-01A were replaced on the MBR-01A1 with newer more advanced systems allowing for less power consumption and in the case of the RADAR suite, five times as much range as the original RADAR array. However the new electronic systems did little to help the MBR-01A1’s performance in space. The MBR-01A1 was intended to be purely a ground unit and performed that mission adequately.
         The EFF refit nearly 60,000 MBR-01As at Juno during the 2176-2177 AD period at a rate of nearly 2500 per month. By the end of 2177 AD, the entire remaining MBR-01A force was converted to MBR-01A1s. An additional 65,000 units were built during the 2177-2183 AD time frame. Thirty-five thousand were constructed on Mars, and the remainder was built on Venus. These units made up the bulk of the defense forces of both Mars and Venus up until the end of the Ceres Conflict in 2185 AD.
