The Rattenfanger was envisioned to be an assault class ‘Mech with superior detection, high mobility, and long range weapons to exterminate scout BattleMechs, thereby denying the opposition vital reconnaissance. Incidentally it could perform the same mission it would remove. Despite thousands of man-hours and millions of C-Bills spent on development, the design was denied factory production. Not for capability failure, but for achieving them without meeting a predetermined weight class of 80 tons.
