Does that mean the article is wrong or they’ve recycled? We’ve all been told the importance of recycling.
I have not seen the source information that is the basis of the article, so I cannot say wether it is incorrect or why. They mention some White House communication that links the two programs but I have not seen that document.
Program elements are not generally recycled. In this case LINK PLUMERIA was definitely not recycled or repurposed.
Perhaps though you meant the article(s) mentioned here were recycled?
LINK PLUMERIA has been active since at least the early 1990s, possibly earlier. Over the years the levels of funding have varied but have generally been low.
And, importantly, LINK PLUMERIA is not an aircraft program and never has been.
Maybe it's the standard "let's hide the money here" R&D line item that emits a production program from time to time.
The idea of a "slush fund" or black budget line item that actually funds some other activity is the thing of movies. When DoD asks for money for some purpose (and gets it), they have to spend that money for that purpose. If they want to use it for something else they have to get approval for a reprogramming action - moving money from one program to another. These reprogramming actions are public, even for classified programs.
For example, years ago the Navy was approved to reprogram funds from LINK PLUMERIA (and several other classified programs) into the X-47B demonstration. Their argument for doing so was that the X-47B was higher priority. In some cases a reprogramming may be done between related programs but this is not always the case (and was not the case in the example I just gave)
IF the Navy was using funds from LINK PLUMERIA for some other purpose without an approved reprogramming action there was a failure of the oversight and budgeting process. If they were caught it would result in a very nasty investigation and the Navy probably wouldn't get a new airplane, a new sub, etc.
