Image-recognition missile
The Terran Knowledge Bank
The Image Recognition Missile was a projectile weapon used by the Terran Confederation and Kilrathi fleets.
The missile locked on a visual source, allowing it to track a single ship without risk of hitting anything else. Locking took several seconds.
The Spiculum IR was a Terran Confederation version of the missile. Image Recognition missiles were found on the Rapier II, Raptor and Gratha.
They were featured in both Weapons of the Terran and Kilrathi Fleets and Borger's All The Sector's Weapons Systems.
