Shouldn't the purchase of the F/A-22s wait until they have been tested?

The Air Force has spent $32 billion on its new F-22 supersonic stealth
fighter. Twenty aircraft have come off the production line and
hundreds more are planned.

But rigorous, independent field testing -- to find out if the F-22
actually works -- hasn't yet begun.

So why not pause production for a few years until the testing is
complete?

Having a production line going takes thousands of people and millions
of $ per day. You can't just stop it because you still have to keep all
those people employed. If you fire them while you screw around, you'll
never get half of them back, and then it will cost you twice as much to
re-start production again. Stopping and re-starting has been tried
before and it's very risky and very costly. It's actually cheaper to
retro-fit an aircraft fleet than stop production.

Your comments strike me as very naive. Suggest you get a job in
industry and a little experience.
