GURPS 3e/V2e question: Explosive Reactive Armor weight

Not a fix, per se, but an update in GURPS Vehicle Expansion 1 [p. VXi27].

Under Extra Detail -Reactive Armor Plates (Late TL7), it is noted that instead of automatically destroying a shaped-charge warhead, the reactive armor plate provides DR 1,000 against it (due to powerful enough warheads actually penetrating RAP in real-life). Second, it introduces Heavy reactive Armor Plates which provide DR 2,000 (by being substantially thicker than the older plates). They weigh more than would be expected if they were just scaled up "old" reactive armor plates but multiplied by the surface area of the tank, shouldn't exceed the weight guidelines you've indicated.

One additional feature available (also p. VXi27) is Applique Armor which allows the RAPs to be bolted (or otherwise attached to the vehicle) giving 2 sets of DR and PD and two sets of weight and mass figures for the vehicle, one with the applique armor and one without. Performance statistics should have a second statistic if the vehicle's weight or mass was important to the calculation.
