If/when the government decides to keep tooling, fixtures, etc.. from a program, someone gets paid to store and maintain that equipment. Sounds trivial but it can amount to a lot of bucks that have to be included in someone's budget which has to be approved by Congress each year. Sometimes, it's a matter of priorities.
I first began calling on Harley-Davidson’s York (PA) motorcycle assembly plant right around the time of the management buy-out. The plant was originally an arsenal that made, among other things, practice aerial bombs for the US Navy. The so-called ‘Bomb Line’ was taking up all kinds of space in the rear of the plant sitting idle under tarps until the Pentagon stopped funding the ‘preservation’ of the equipment. Nobody ‘ordered’ the equipment to be scrapped. It just happens when the money dries-up.
