And This is What Happens
As usual, the DoD can't make up its mind. One reason for this is CYA, the other Congress, and is 30%/70%. Congress is great at mandates but not funding them initially nor sustainably. I remember when the F-35 maintenance was contracted to be maintained by LMT and thought "Yeah, that's a bad idea." for a multitude of reasons. But no one listens to the "Evil Contractor" (Fuck you Obama), even when they are the "Disinterested 3rd Party" who's job it is to give good advice to the government given the information available at the time.
The classic example of Congress falling flat is GPS M-Code: All DoD systems were to be able to receive M-Code in 2017... it still hasn't happened and it will be at least another decade and a half. The reason is pure cost: Cost of creating the new chipset production line to the complete boxes. Even with modifying existing systems, instead of wholesale replacement, it costs in the area of $40,000 - $60,000 per RECEIVER, to do the upgrade. And these upgrades can't be done in the field. New box's are in the $80,000 - $100,000 range. Now throw in the downtime for the item the box is pulled from, sent back to the OEM for re-manufacture - pulling a card out and replacing it with a new one - ATP'ing at the OEM, retesting at the Program Office to re-certify the modification, and one gets to understanding the costs involved with 10's of thousands of devices: missiles to nuclear powered ships, subs, aircraft, HUMVEEs, tanks, radio's, etc.
