I was counting the Titan IV as what it evolved into. It really is different
enough that it is a Titan in name only. It can put 47,800 lb into LEU.

I still see enough of Thor in Delta III that I would consider it a decendent
of the Thor IRBM.

I don't know what Delta II uses for guidance these days, but in 92 they
used what I would consider a classic computer.
