Engineering:List of NRO launches

From HandWiki
Short description: American spy satellites


The National Reconnaissance Office logo

This is a list of NRO Launch (NROL) designations for satellites operated by the United States National Reconnaissance Office (NRO). Those missions are generally classified, so that their exact purposes and orbital elements are not published.

However, amateur astronomers have managed to observe most of the satellites, and leaked information has led to the identification of many of the payloads.

Notes

  1. While the Space Shuttle had nine launches with NRO payloads throughout the late 1980s and early 1990s, this was the first from Kennedy officially acknowledged by the NRO.
