It's TACIT RAINBOW, not "Tasset Rainbow., which was why you didn't find anything.
But TACIT RAINBOW was a project to develop a jet-powered mini drone, not a missile. It was one of only two weapons systems to be cancelled after
undergoing full-up RDT&E; the other was the Sergeant York air defense gun.
But the thing was exceeding its budget, and Northrop had a very bad reputation for performance screwups and budget overruns at the time. I think it
went down around 1990.
