This is just me, but my idea of it being a experimental weapon could tie to CROAgent's idea of PT (Promethean Technology). Let me explain:

The UNSC could have found the PT on another planet and began to experiment with it, which resulted in a unstable and powerful artifact (it could've been labled as a artifact rather than a weapon, explaining why it wasn't mention by Doc). It's reasons for being on the ship was to transport to an advance lab on another planet for further testing. However, the Feds' Control (not Carolina) somehow learned of it and decided to steal the PT from the UNSC to finally defeat the New Republic by using it. I'm assuming that Carolina somehow learns of the PT after breaking into Control and that she's acting as Locus' superior in order to rescue the Blood Gulch Crew and prevent them to use it right from under their noses.

I think this hypothesis is a little better and gives a purpose to the mysterious box. Any thoughts?
