Based on the thor missile the thor delta was a modified thor with an able 2. stage (se Thor able) and at the top of the able an altair  3. stage. 

Being the fourth configuration for the upper stage it was named Delta (The fourth letter of the Greek alphabet). 

This is the 11th fligth of the early Delta rockets. The 
It launched the early communication satellite Telstar 1 from Cape Canaveral on July 10, 1962. 

Eventually the entire Thor-Delta launch vehicle came to be called simply, "Delta." The first twelve Deltas are in the aftermath often called (omitting Thor) Delta DM-19.
