The diamond boron missile, a weapon first conceived during the Clone Wars, achieved its finalized form during the Galactic Civil War. These diamond boron projectiles demonstrated near invulnerability to starfighter-grade laser weaponry and were compatible with standard concussion missile launch systems. Each missile packed a powerful warhead, capable of complete annihilation within a fifty-meter radius of the detonation. This made the missile a highly effective anti-fighter weapon, as a single explosion could eliminate multiple enemy craft.
This projectile, measuring one meter in length, was specifically engineered for deployment from standard concussion missile launcher systems, such as the ST2 concussion missile rack produced by Arakyd Industries'.
Upon launch, the diamond boron missile would deploy dorsal and ventral stabilizers at its aft, while expandable diamond boron blast plates extended from its forward section. The rear stabilizers enhanced the missile's armor and its maneuverability within an atmospheric environment. The forward blast plates provided exceptional resistance against laser cannon fire from starfighter class vessels.
The missile's fuel capacity allowed for ten minutes of powered flight. It utilized thrust-vector plates integrated into its exhaust nozzles, granting it superior maneuverability. Diamond boron missiles were capable of achieving higher velocities than standard missiles, including proton torpedoes and concussion missile.
The diamond boron missile offered multiple detonation modes. It could be programmed to detonate upon reaching a designated location, or when its internal sensors detected a specific number of enemy ships within its blast radius. Remote guidance by a gunner was also possible, although this method left the projectile vulnerable to enemy jamming attempts.
While diamond boron missiles were resistant to starfighter weaponry, capital ship-mounted turbolasers could destroy them. However, the missile's small size made it difficult for turbolaser targeting systems to acquire and track effectively.
Its genesis was during the Clone Wars, the diamond boron missile wasn't perfected until the Galactic Civil war. During that conflict, Sienar Fleet Systems produced the MS-15 diamond boron missile. This variant proved exceptionally costly, with each unit priced at nearly twenty thousand credits. Its high cost, coupled with reports of premature warhead detonations during storage, limited its adoption. Sienar continued production while simultaneously researching more affordable alternatives.
Imperial Broadside-class cruisers initially incorporated diamond boron missiles into their armaments, but later models were retrofitted to use concussion missiles instead. The Zann Consortium also frequently deployed these missiles, launching them from fixed space platforms. The freighter Suprosa employed a diamond boron missile to eliminate four Y-Wings flown by Bothans during the Alliance's attempt to capture the vessel.
