A Cruise Disruptor is a missile that causes little to no hull or shield damage, but disrupts the cruise engine of a ship to reduce it to normal speeds. Cruise Disruptors are fired from special launchers that fit in a Cruise Disruptor slot on a ship; these slots can also be used on certain ships to mount Torpedo Launchers.
Cruise Disruptors are used when attacking ships that would rather flee from combat. Often, Cruise Disruptors are used by NPC factions to keep their enemies from getting away, giving pursuing fighters a chance to catch up and bring down their prey. Players often use Cruise Disruptors while camping an enemy base, hitting traders leaving the base to allow the player to destroy the trader ship and tractor in its cargo for sale elsewhere.
