Narrative:

F18 not reported by center as traffic until after occurrence and after we quizzed center if they had seen the on coming traffic. Callback conversation with reporter revealed the following information: reporter states the aircraft was climbing and TCASII idented the traffic. The climb took the flight thorough the F18 altitude. Captain called center and controller claimed they did not have the traffic until after captain idented it. Seems strange to reporter that, since they were at FL180, that ATC did not know about the fgt. No further follow up.

CAPT CALLED CTR AND CTLR CLAIMED THEY DID NOT HAVE THE TFC UNTIL AFTER CAPT IDENTED IT. SEEMS STRANGE TO RPTR THAT, SINCE THEY WERE AT FL180, THAT ATC DID NOT KNOW ABOUT THE FGT.
