The behavior of the USAF across it's history supports that argument,
they were a latecomer to GPS, not an early adopter. The bombers
depended on radar and visual sightings once they entered the bombing
run. One suspects their involvement was more attributeable to
politics (increasing the accuracy of manned bombers increases their
viability, and being involved in a program that was in space but not
USAF controlled) as any desire for accuracy.

They want it because it's available. There was certainly no such
clamor during the design phase.
