The Pre-WW3 mission of USAF C-37B 11-0550: US Military Brass on a Pacific Rim Tour to get all their ducks in a row.

11-0550 is a USAF C-37B executive transport jet, the military version of the Gulfstream 550.

This aircraft carries no national insignia and is completely unmarked save for the aircraft's serial number.

In the past, the aircraft has been used to ferry US Generals and Admirals around the world. For a relatively small aircraft, the C-37B definitely has some legs.

In this case, I would suggest the aircraft was carrying USAF or USSF brass due to the pick up at Colorado Springs described below and it's later activities in the Southern Hemisphere...

Here's a short log of 11-0550's movements over the past week or so. The information is taken from the ADS-B data collated and displayed at adsbexchange.com.
