Narrative:

Scheduled airlines flight from san to slc was being controled by ZLA with a radar vector direct to tnp. As first officer, I was in control of the medium large transport, flying in the right seat. At approximately xyz while climbing through approximately FL200, a navy fgt climbed through our altitude and crossed over our aircraft. West/O any warning the bottom of the fct filled the captain's side window and crossed directly over our fuselage. Looking out the right rear side of my side window, I saw the navy fgt in a very nose high attitude on a course of approximately 150 degrees. He appeared to level off at approximately 2000' above our altitude while maintaining course and a very nose high attitude. The captain then asked ZLA if they were painting an aircraft that had just crossed over us. The controller stated there was an emergency navy aircraft in the area and he would check. By phone later the center supervisor stated the fgt had been cleared form 16000 to 23000', and that he had stated he had us 'in sight.' my view of the gear doors of the fgt out the captain's side window indicates he did not have us in sight when he crossed within 100-200' of our aircraft. A warning from center would have saved several anxious mins.
