Or at least could have been produced in 1972:

For those young enough for this to be simply amazing, you need to remember that when IBM introduced the Selectric typewriter in 1961 it was an amazing leap forward, utilizing a "golf ball" that could print faster than a traditional typewriter. Three years later, IBM introduced the MT/ST (Magnetic Tape/Selectric Typewriter) that added a magnetic tape drive to the Selectric. The magnetic tape was the first reusable storage medium for typed stuff, allowing it to be stored, replayed, corrected, reprinted whenever needed, then erased to be reused. This might seem like nothing to today's computer users, but before that making a correction to a typo on a document was labor-intensive, particularly if there were carbon copies involved. The MT/ST probably marked the beginning of word processing as we know it today.
Making corrections to documents became a lot easier in 1969 when IBM introduced the MagCard, which actually stored a document on a storage card device. In 1972 Lexitron and Linolex developed a similar word processing system but included video display screens and tape cassettes for document storage. The screen made it possible to enter and edit text without having to print hard copies.
It was in 1972-73 that Vydec introduced its first word processor, which featured floppy disk storage that would hold 80 to 100 pages of text instead of the one page the magnetic cards held. I remember these machines well; if you were really good with them you could actually paginate documents, much to the amazement of authors standing around in a circle watching.
IBM introduced its memory typewriter in 1974 and Wang introduced the 2200 Series in 1976. WordStar, one of my favorite old word processing programs, shipped in 1979. Also in 1979, Apple introduced the Apple II Plus, Intel introduced the 8088 microprocessor, and Texas Instruments introduced the TI-99/4 personal computer. The advent of the personal computer would spell the end of the dedicated word processing machines.
Wow. Electronic word processors had punched cards, and magnetic memory, in 1964. In 1972, they had adavanced so that users could edit text on a video screen before printing a hard copy. I heard about these today from a relative who informed me that when he was a company clerk in the service in 1971 (stationed at MACV), the Army had multiple floppy-disk using word processors at his unit. This source does not wish to be named, but is the person who showed me how to program computers, based on what he learned in the Army, during Vietnam. His opinion is that the memos could have been easily produced using systems that were available to him and many others in 1971. He was only ranked E-5.
So I guess Killian might have had access to computerized word processing machines utilizing the Times Font, text centering, superscript, and a tab-stob at 4".
Have I mentioned that the faux letterhead looks to me like the output from a machine that uses struck type, like an old line printer?
It looks to me like that letterhead was stored on a punched card, macro, tape, or similar. It consistently has a "descended" last character on each line -- as though the computer printer "got ahead of itself" as it came to the spot where it needed to carriage return but was still in the process of pounding the last letter. That's the kind of bug I would expect in such a device, speaking as a computer programmer and occassional builder of electronics.
My money would be on Killian having made paper cards or storage cartridges of forms, such as this personal letterhead.
Again, the comparisons of Times New Roman to Times are comparing Times to Times after one of them got their named changed by a lawsuit from Linotype. Linotype made print faces for line printers, such as the kind you could hook up to 1960's-vintage computers.
