Narrative:

Departing runway 17 at sps, captain was PF. Departure instructions from sps tower were to climb to 3100 ft, fly heading 150 degrees, cleared for takeoff. After climbing through acceleration altitude, prior to starting a l-hand turn to heading 150 degrees, I checked the TCASII was clear to the left and looked out the l-hand cockpit side window to clear the airspace. I saw a T-38 military jet trainer that had just departed runway 15R. I saw the planform view of the aircraft. Initially, I was unable to determine if the aircraft was turning left or right. I stopped the climb smoothly but aggressively, leveled off the aircraft at 1800 ft MSL. I again checked the conflict aircraft and determined that it was turning right, it was a conflict and was closing on our position. I would estimate a few hundred yards between aircraft. Continuation of either the climb to the assigned altitude or the turn to assigned heading would have resulted in a collision. There was no warning or information on the aircraft from the controller or the TCASII.

Title: AN SF3 CAPT, DEPARTING RWY 17, RPTED THAT SPS TWR DID NOT MAINTAIN SEPARATION BTWN HIS FLT AND A T38, CAUSING AN NMAC.

Narrative: DEPARTING RWY 17 AT SPS, CAPT WAS PF. DEP INSTRUCTIONS FROM SPS TWR WERE TO CLB TO 3100 FT, FLY HDG 150 DEGS, CLRED FOR TKOF. AFTER CLBING THROUGH ACCELERATION ALT, PRIOR TO STARTING A L-HAND TURN TO HDG 150 DEGS, I CHKED THE TCASII WAS CLR TO THE L AND LOOKED OUT THE L-HAND COCKPIT SIDE WINDOW TO CLR THE AIRSPACE. I SAW A T-38 MIL JET TRAINER THAT HAD JUST DEPARTED RWY 15R. I SAW THE PLANFORM VIEW OF THE ACFT. INITIALLY, I WAS UNABLE TO DETERMINE IF THE ACFT WAS TURNING L OR R. I STOPPED THE CLB SMOOTHLY BUT AGGRESSIVELY, LEVELED OFF THE ACFT AT 1800 FT MSL. I AGAIN CHKED THE CONFLICT ACFT AND DETERMINED THAT IT WAS TURNING R, IT WAS A CONFLICT AND WAS CLOSING ON OUR POS. I WOULD ESTIMATE A FEW HUNDRED YARDS BTWN ACFT. CONTINUATION OF EITHER THE CLB TO THE ASSIGNED ALT OR THE TURN TO ASSIGNED HDG WOULD HAVE RESULTED IN A COLLISION. THERE WAS NO WARNING OR INFO ON THE ACFT FROM THE CTLR OR THE TCASII.
