The Dragon's Teeth were an electronic warfare system invented by the Royal Manticoran Navy.
Each missile was basically a powerful decoy. As it headed for the enemy, it made itself look like a Ferret-class light attack craft's entire missile load, approaching in a concentrated salvo which drew heavy countermissile fire.
Dragon's Teeth were developed as part of the Ghost Rider program, and used in combination with Dazzlers. (HH9)
