Narrative:

We were cleared into position and hold on runway 18. While I was performing my before takeoff duties, I recall overhearing the controller issue missed approach instructions to the T-38 on practice approach to the sjt airport. At that time I did not hear the runway to which he was flying the approach, but I do remember the local controller instructing the T-38 to execute his missed approach 1 NM prior to the runway threshold and 'do not overfly the departure or arrival end of runway 18, departing traffic.' we were then cleared for takeoff on runway 18, runway heading. The controller did not provide us with a TA of the inbound T-38 prior to takeoff. After liftoff, the captain called for 'gear up.' shortly after (approximately 300-400 ft AGL), I heard the controller state in an anxious tone, 'turn left!' the captain, then I, visually acquired the T-38 at our 1 O'clock position in level flight at about 400 ft AGL approaching the threshold to runway 3 (which intersects at the departure end of runway 18). The captain made a descending left turn to evade the T-38. The controller continued to issue commands to the T-38 to make an immediate left turn, at which time I observed the T-38 execute a climbing left turn and pass off the right side of our aircraft. The captain having leveled the aircraft at 300-350 ft AGL, then began a climb to the northeast toward bwd on course, and the flight concluded without incident. TCASII had been selected to the automatic mode prior to the before start checklist, but the target was idented on the mfd as 'TA only' and no aural alert was given due to the low altitude of our aircraft. Contributing factors: the T-38 was performing a practice approach, opposite direction to the flow of traffic, to an intersecting runway with a tailwind (wind 190 degrees at 12 KTS). The T-38 was operating on a UHF frequency. We were on VHF, therefore, we could not overhear his transmission to the local controller. A TA was not issued to us prior to takeoff.

Title: SAAB 340 FLT CREW IS REQUIRED TO TAKE EVASIVE ACTION ON DEP AS T38 TRAINER DOES LOW APCH OVER THEIR ACFT.

Narrative: WE WERE CLRED INTO POS AND HOLD ON RWY 18. WHILE I WAS PERFORMING MY BEFORE TKOF DUTIES, I RECALL OVERHEARING THE CTLR ISSUE MISSED APCH INSTRUCTIONS TO THE T-38 ON PRACTICE APCH TO THE SJT ARPT. AT THAT TIME I DID NOT HEAR THE RWY TO WHICH HE WAS FLYING THE APCH, BUT I DO REMEMBER THE LCL CTLR INSTRUCTING THE T-38 TO EXECUTE HIS MISSED APCH 1 NM PRIOR TO THE RWY THRESHOLD AND 'DO NOT OVERFLY THE DEP OR ARR END OF RWY 18, DEPARTING TFC.' WE WERE THEN CLRED FOR TKOF ON RWY 18, RWY HDG. THE CTLR DID NOT PROVIDE US WITH A TA OF THE INBOUND T-38 PRIOR TO TKOF. AFTER LIFTOFF, THE CAPT CALLED FOR 'GEAR UP.' SHORTLY AFTER (APPROX 300-400 FT AGL), I HEARD THE CTLR STATE IN AN ANXIOUS TONE, 'TURN L!' THE CAPT, THEN I, VISUALLY ACQUIRED THE T-38 AT OUR 1 O'CLOCK POS IN LEVEL FLT AT ABOUT 400 FT AGL APCHING THE THRESHOLD TO RWY 3 (WHICH INTERSECTS AT THE DEP END OF RWY 18). THE CAPT MADE A DSNDING L TURN TO EVADE THE T-38. THE CTLR CONTINUED TO ISSUE COMMANDS TO THE T-38 TO MAKE AN IMMEDIATE L TURN, AT WHICH TIME I OBSERVED THE T-38 EXECUTE A CLBING L TURN AND PASS OFF THE R SIDE OF OUR ACFT. THE CAPT HAVING LEVELED THE ACFT AT 300-350 FT AGL, THEN BEGAN A CLB TO THE NE TOWARD BWD ON COURSE, AND THE FLT CONCLUDED WITHOUT INCIDENT. TCASII HAD BEEN SELECTED TO THE AUTO MODE PRIOR TO THE BEFORE START CHKLIST, BUT THE TARGET WAS IDENTED ON THE MFD AS 'TA ONLY' AND NO AURAL ALERT WAS GIVEN DUE TO THE LOW ALT OF OUR ACFT. CONTRIBUTING FACTORS: THE T-38 WAS PERFORMING A PRACTICE APCH, OPPOSITE DIRECTION TO THE FLOW OF TFC, TO AN INTERSECTING RWY WITH A TAILWIND (WIND 190 DEGS AT 12 KTS). THE T-38 WAS OPERATING ON A UHF FREQ. WE WERE ON VHF, THEREFORE, WE COULD NOT OVERHEAR HIS XMISSION TO THE LCL CTLR. A TA WAS NOT ISSUED TO US PRIOR TO TKOF.
