Frankly, I would have expected the folks at

contractor(s) to have used assembler in those days under the guise of
"efficiency;" but Fortran-IV would definitely have been popular at many
contractors that would have been doing the work. The article mentions
Fortran-V which I find interesting because I did not believe it was
really much of a thing (i.e. it was never standardized). Basically, as
I understood it from my Fortran peeps at DEC/Intel, F-V was the Waterloo
extensions (a.k.a. WatFor) that got picked up by most people and in
particular, IBM added to the FORTRAN/G or H compiler for the S/360. DEC
had gone in a different direction still with VMS FORTRAN, although I
believe they had picked up the things like WRITE(*) from Waterloo.
And WATFIV as well, as I recall from my student days; it was closer to
FORTRAN than WATFOR was (both were "student" compilers e.g. better error
messages but not the best of generated code).
