Hi Daniel,

Good question.  There's a waiver process that national security launches can go through to not abide by these requirements.  There was a really interesting paper at the AMOS conference this year that talked about how often these waivers were requested/granted if you're interested.

Is there any requirement on NRO to ensure that spent rocket bodies are
de-orbited promptly?  I have to prove that my Cubesats will burn up within 25
years, but apparently it is OK for larger spent rockets to stay up for much
longer. Most of the GTO launches of the past decade still have their upper
stages in elliptical orbit. I will be interested to see how long this RB lasts
(probably longer than I have left).
