During initial climb out and crosswind turn from Runway XX we received a TA 'Traffic' alert and then an almost immediate RA 'descend descend' alert. Since we were very low to the ground in our initial takeoff climb I was unable to descend so I stopped the climb and continued our left turn. Immediately out our left window and slightly higher than us was a USAF T-38 fighter trainer entering a left breaking turn. After leveling the aircraft we received the RA 'clear of conflict' and I stopped the turn in the assigned takeoff direction of 280. Shortly after we were given a climb by ATC to our cruise altitude of 9;000 ft. We did not encounter any further incident.High volume of USAF training aircraft at that airport. Given a takeoff clearance while a training aircraft was entering its 'overhead break' maneuver. We were given a takeoff clearance to make an early turn to heading 280 (which we did).Do not clear an aircraft to takeoff until airborne traffic is well clear of the airport.
Upon initial climb after takeoff; we received a TA and then an RA and immediately followed RA. Upon looking out the window; spotted a fighter jet within proximity of the aircraft.Corrective action was taken per the RA and flight continued as normal. Aircraft was cleared for takeoff and climb out within too close of proximity of other aircraft in traffic patternDo not clear aircraft for takeoff when other aircraft will be in too close proximity
