No.

From what I know about military contracts: they are very unstable. Some days, the armies (naval, ground, marine, air) don't order anything. Some days, they order a hell lot of things in a very short time so that the company can't supply this sudden demand.

By keeping the company small, they can survive from low demand during days, weeks or months.

Small history about GPS: During the Gulf War, the armies wanted to buy many military grade GPS (before 2000, the military signal was far more accurate than civilian signal) but companies weren't able to supply this demand.

So, the President ordered the NAVSTAR GPS to stop the Selective Availability (SA), the 'engine' in which it alters the civilian signal so the GPS is not accurate in 100 meters range, to avoid the terrorist attack.

By shutting off the SA, the Army could use the civilian GPS during the Gulf War, because it was as accurate as military-grade GPS.

Of course, at the end of the war, the SA was re-activated until 2000.

Hope you understand the big disadvantage of military contracts. That's why military-oriented compagnies sells stuffs to the civilians in order to survive during low periods.

I can be wrong, but this is what I understood in this domain.
