Narrative:

I was vectoring, fgt X, flight of 2, for a visual approach to bergstrom AFB from approximately 20 northwest. I assigned a heading of 150 degree to align the formation on final for a straight in. I asked fgt X if he had bergstrom in sight and was informed that he did. I cleared X for a visual approach to runway 17R overhead pattern to maintain 3000' until past austin airport. Fgt X continued to turn to an approximately heading of 170 degree which aligned him straight in to austin airport. As visibility was only 7 miles, I felt it possible that X had mistaken austin for bergstrom. I made sure that austin tower (who already had a point out) was aware of fgt X position.) I advised X that he was approximately 1 mile right of course and told him to turn left to heading 150 degree to line up on final. I verified that X had bergstrom AFB in sight, again cleared him for a straight in visual and told him to contact bergstrom tower. He acknowledged and I heard him tell the wing men to go to tower frequency. The flight continued across the final on the same heading in a slow descent. At this time air carrier Y broke ground from austin runway 13R. Heading east, the aircraft passed each other approximately 3 east of austin with air carrier Y climbing from 2700' and the 2 fgt's descending through 2400.

Title: LESS THAN STANDARD SEPARATION BETWEEN FLT OF TWO MIL FGT AND AN ACR ACFT. OPERATIONAL ERROR.

Narrative: I WAS VECTORING, FGT X, FLT OF 2, FOR A VISUAL APCH TO BERGSTROM AFB FROM APPROX 20 NORTHWEST. I ASSIGNED A HEADING OF 150 DEG TO ALIGN THE FORMATION ON FINAL FOR A STRAIGHT IN. I ASKED FGT X IF HE HAD BERGSTROM IN SIGHT AND WAS INFORMED THAT HE DID. I CLRED X FOR A VISUAL APCH TO RWY 17R OVERHEAD PATTERN TO MAINTAIN 3000' UNTIL PAST AUSTIN ARPT. FGT X CONTINUED TO TURN TO AN APPROX HEADING OF 170 DEG WHICH ALIGNED HIM STRAIGHT IN TO AUSTIN ARPT. AS VISIBILITY WAS ONLY 7 MILES, I FELT IT POSSIBLE THAT X HAD MISTAKEN AUSTIN FOR BERGSTROM. I MADE SURE THAT AUSTIN TWR (WHO ALREADY HAD A POINT OUT) WAS AWARE OF FGT X POSITION.) I ADVISED X THAT HE WAS APPROX 1 MILE RIGHT OF COURSE AND TOLD HIM TO TURN LEFT TO HEADING 150 DEG TO LINE UP ON FINAL. I VERIFIED THAT X HAD BERGSTROM AFB IN SIGHT, AGAIN CLRED HIM FOR A STRAIGHT IN VISUAL AND TOLD HIM TO CONTACT BERGSTROM TWR. HE ACKNOWLEDGED AND I HEARD HIM TELL THE WING MEN TO GO TO TWR FREQ. THE FLT CONTINUED ACROSS THE FINAL ON THE SAME HEADING IN A SLOW DESCENT. AT THIS TIME ACR Y BROKE GND FROM AUSTIN RWY 13R. HEADING EAST, THE ACFT PASSED EACH OTHER APPROX 3 EAST OF AUSTIN WITH ACR Y CLIMBING FROM 2700' AND THE 2 FGT'S DESCENDING THROUGH 2400.
