I wouldn't say it's deliberate...we've been screaming for new machines since I've been in. That's coming up on 13 years.
Maintinence is currently a nightmare. So is getting missions done, as the electronics and internal systems are beginning to break more and more.
Maintenance was a nightmare when I was in during the late 80's. I can still remember the fiasco's trying to get the hanger queen to fmc status after weeks of part raping. It's got to be 10x worse for you guys. Thanks for what you do. From someone who's been there, it's a very difficult job.
