Wouldn’t doubt it although punched mylar went away in the 80s, early 90s. I was at SAC HQ in 85 when a problem arose with maintaining targeting on the Titans that were being drawn down. They did away with the ancient System 70 equipment that punched the tapes but there was another year left before the last bird came out of the hole. We finally found a tape unit at a test facility to punch out a set of target packages that would be used until the last deactivation. I was using the SACCS system before they went to the floppy disks. The point was not to have any outside feeds, only direct system to system. Better security.
In 2006 the Mk 12 R/S test set that I used in 1972 was still in use at VAFB.
