Dead-Fire Missiles were prototype weapons developed by House Kurita to offset the increasing cost of military hardware. To reduce cost, the guidance systems of standard long range and short range missiles were removed and replaced with larger warheads. Though this obviously increased the damage the missiles inflicted, the lack of guidance made the systems very difficult to use. These systems existed for only a brief time before being superseded by Medium Range Missile launchers.
 Game Rules
Any standard LRM or SRM launcher could be loaded with Dead Fire Missiles. These missiles would inflict one extra point of damage (2 points per LRM, 3 per SRM) but when using the cluster hits table, the controlling player rolled 3D6 and used the two worst rolls to determine the number of missiles that hit.
When a launcher loaded with Dead Fire Missiles is hit by weapons fire, in addition to the launcher being destroyed, the missiles loaded in the rack explode and inflict more damage on the internal structure. The damage inflicted is equal to the number of missiles multiplied by their damage rating. An LRM-15 loaded with Dead Fire Missiles would inflict 30 points of damage for example.
Dead Fire Missiles were replaced by Medium Range Missile launchers and are no longer valid in game play.
