The diamondboron missile was a weapon developed sometime during the Clone Wars, but only truly refined at the height of the Galactic Civil War. Diamond boron missiles were nearly impervious to starfighter-scale laser weapons and could be fired from most standard concussion missile launchers. They were equipped with powerful warheads capable of completely destroying everything within five-hundred meters from the point of detonation. Thus, the missile proved itself an effective weapon against fighters, since a single blast could easily take out several at a time.
Despite these advantages, the missile was prohibitively expensive, with each unit demanding an investment upwards of 20,000 credits. It therefore fell into disuse as newer and cheaper alternatives were developed.
