Narrative:
While on final approach to runway 31; we were overflown by a heavy KC135 with vertical separation being 300-500 ft. On approximately 1 mile final for runway 22; tower instructed the KC135 to turn eastbound and climb to 5;000 ft (our altitude). This caused the KC135 to fly over the final approach course for runway 31. The KC135 climbed to 5;500 ft on their own to avoid our airplane. If the KC135 did not climb; this situation would have been ever more dangerous than it was. Wake turbulence from the heavy KC135 could have caused difficulty controlling our airplane while on final approach.
