Narrative:

We received a visual clearance from ATC. All normal and per SOP including speed and on GS landing runway 30 in vps. When we were inside the FAF about 1000 ft from the touchdown zone; we received a TA. I was the PNF and looked at our TCAS to find a target behind us about 1 mi and 600 ft up. I told the first officer to continue the approach while monitoring the traffic. It was continuing to descend and catching us quickly. I called ATC that we were 2 mi final on runway 30 and asked if there was another aircraft landing. I was extremely concerned that this aircraft was landing on top of us and that ATC had 2 aircraft landing the same runway at the same time. At this time the aircraft was behind us about 1/4 mi and at 400 ft above us. ATC said it was an F18 and that he had us in sight. I was ready to break off the approach with a fairly hard l-hand turn; but opted not; due to the fact we were so low. I had no escape route away from this traffic. I felt like this was aspen all over again. At this time I saw the F18 speed right above us (doing at least 250 KTS) tracking the same localizer as we were to runway 30. All of this happened in less than 15 seconds. The wind was blowing hard with light to moderate turbulence down the GS. No windshear advisories were in affect (broadcasted on the ATIS); but the first officer and myself briefed expected windshear. If we did get into windshear; the miss called for a climb to 3000 ft and turn to crestview VOR at the decision ht. Which means that if we did have to go miss at this time there would be no doubt in my mind we would have collided with the F18. We had no warning of this aircraft behind us until the TA. I called ATC once on the ground; and they apologized for not letting me know he was coming from behind and would be overflying me. Which is still unacceptable because I would not have allowed this to happen. We had no escape route once we were cornered in this situation. They told me that they have done this in the past and it is not a problem. I disagree.

Narrative: WE RECEIVED A VISUAL CLRNC FROM ATC. ALL NORMAL AND PER SOP INCLUDING SPD AND ON GS LNDG RWY 30 IN VPS. WHEN WE WERE INSIDE THE FAF ABOUT 1000 FT FROM THE TOUCHDOWN ZONE; WE RECEIVED A TA. I WAS THE PNF AND LOOKED AT OUR TCAS TO FIND A TARGET BEHIND US ABOUT 1 MI AND 600 FT UP. I TOLD THE FO TO CONTINUE THE APCH WHILE MONITORING THE TFC. IT WAS CONTINUING TO DSND AND CATCHING US QUICKLY. I CALLED ATC THAT WE WERE 2 MI FINAL ON RWY 30 AND ASKED IF THERE WAS ANOTHER ACFT LNDG. I WAS EXTREMELY CONCERNED THAT THIS ACFT WAS LNDG ON TOP OF US AND THAT ATC HAD 2 ACFT LNDG THE SAME RWY AT THE SAME TIME. AT THIS TIME THE ACFT WAS BEHIND US ABOUT 1/4 MI AND AT 400 FT ABOVE US. ATC SAID IT WAS AN F18 AND THAT HE HAD US IN SIGHT. I WAS READY TO BREAK OFF THE APCH WITH A FAIRLY HARD L-HAND TURN; BUT OPTED NOT; DUE TO THE FACT WE WERE SO LOW. I HAD NO ESCAPE RTE AWAY FROM THIS TFC. I FELT LIKE THIS WAS ASPEN ALL OVER AGAIN. AT THIS TIME I SAW THE F18 SPEED RIGHT ABOVE US (DOING AT LEAST 250 KTS) TRACKING THE SAME LOC AS WE WERE TO RWY 30. ALL OF THIS HAPPENED IN LESS THAN 15 SECONDS. THE WIND WAS BLOWING HARD WITH LIGHT TO MODERATE TURB DOWN THE GS. NO WINDSHEAR ADVISORIES WERE IN AFFECT (BROADCASTED ON THE ATIS); BUT THE FO AND MYSELF BRIEFED EXPECTED WINDSHEAR. IF WE DID GET INTO WINDSHEAR; THE MISS CALLED FOR A CLB TO 3000 FT AND TURN TO CRESTVIEW VOR AT THE DECISION HT. WHICH MEANS THAT IF WE DID HAVE TO GO MISS AT THIS TIME THERE WOULD BE NO DOUBT IN MY MIND WE WOULD HAVE COLLIDED WITH THE F18. WE HAD NO WARNING OF THIS ACFT BEHIND US UNTIL THE TA. I CALLED ATC ONCE ON THE GND; AND THEY APOLOGIZED FOR NOT LETTING ME KNOW HE WAS COMING FROM BEHIND AND WOULD BE OVERFLYING ME. WHICH IS STILL UNACCEPTABLE BECAUSE I WOULD NOT HAVE ALLOWED THIS TO HAPPEN. WE HAD NO ESCAPE RTE ONCE WE WERE CORNERED IN THIS SITUATION. THEY TOLD ME THAT THEY HAVE DONE THIS IN THE PAST AND IT IS NOT A PROB. I DISAGREE.
