The photos today are from two events. 

First, there is a photo of an example of an Atlas F/Trident configuration.  The last test launch of this type was on this day in 1971.  This configuration launched the ABRES-3 system (Advanced Ballistic Reentry System). Photo Credit: USAF found on the public Astronautix website (Gunter’s Space Page. Retrieved May 23, 2024, from https://space…skyrocket.de/doc_lau_det/atlas-ef_trident.htm). 

The second photo is the launch of NROL-15 on Delta IVH in 2012.  Here is the caption for the photo, which was found on the ULA Flickr photo archive:
