Originally designated the "Weapon-Armed 'Mech-Alpha", the first generation BattleMech produced by the Capellan Confederation in 2483 was widely known for its use of Inferno missiles. After eleven years of service, a second generation model began production on Boardwalk, and observers noted that this second-generation version was not a "WAM-B", but a "Fire-B" prompting the BattleMech to be re-designated as the FRB-1E Firebee.

Eventually a third generation Firebee began production on Exedor in 2524. This factory continued production until it was destroyed during the First Succession War.[4]

The Firebee has a top speed of 86 km/h, fast for a light 'Mech of its day. It was also quite maneuverable, with enough jump jets to leap 150 meters in the air. Six tons of armor provides significant protection for such a small machine.[4]

Weapons and Equipment[edit]

The 2E Firebee mounts a Star Cutter 80cm Large Laser, giving it respectable firepower. Up close, four Maui Crossbow SRM-2 launchers can unleash eight missiles. With its two tons of ammunition for the SRM launchers, MechWarriors can use either inferno or standard missiles. Either way, the Firebee is a potent anti-vehicle platform.[4]


  • WAM-B/FRB-1E 
    The original Firebee used a single LRM-5 backed up by a trio of SRM-2s. The Primitive Engine provided a top speed of 85 km/h, more than enough to engage armored vehicles and infantry, and supporting heavier units. The lack of jump jets, combined with six and a half tons of Primitive Armor, forced pilots to pay attention to the terrain to insure they could move effectively[3]. BV (2.0) = 452[7]
