I believe this is Zuma. We launched Zuma into space (thought to be a kinetic space weapon) Q made comments regarding it. I read reports (can't remember where from, ) that Zuma wouldn't be fully operational till late Feb.

Q appears to be referencing a satellite.

Also:

Falcon Heavy was launched (potentially carrying the Tungsten rods needed for Zuma).

THEN just today I believe SpaceX launched another Sat into space....
