I rather doubt it. There were a variety of such terms:

snafu [= Situation Normal: All F_____ Up]
fubb [= F______ Up Beyond Belief]
janfu [= Joint Army-Navy F_______ Up]
tarfu [= Things Are Royally F_______ Up]

See excepts from The Mother Tongue by Bill Bryson, at
http://www.tower.org/library/the_mother_tongue.html; penultimate paragraph.

There are many more such terms {fumtu = F_____ Up More Than Usual}, but I don't know if they originated during WWII, or after. Once can enjoyably find them by googling the above examples. FUJIGMO
