Thank you so much, M3 Mitch. Obviously I was searching in all the wrong places.
What a wealth of information at that link.
We (US military) did have quite a few naming systems that overlapped and clashed over the years.
This is so much fun. I wish I has asked my father more about it when he was alive. He flew the B-52 and and another B that I think was B57 (If I remember correctly that is the plane we were going to bomb the Soviets in Cuba with during the missile crisis) but the Gooney Bird was always his favorite. We didn't see much of him during that crisis because he was literally sleeping on the flight line along with all the crewmembers and groundcrews. I got to tour those planes on military celebration days and all I remember is that the B-52 was crawling inside with little green spiders. Odd memory. I still miss SAC. "Peace Is Our Profession."
Now I am rambling and I'll stop but I really thank you for helping me with this.
