Narrative:

A us customs small transport made an east departure from hst and turned south to remain clear of the mia TCA. While climbing through 5000' and completing a right turn, spotted an large transport approximately same altitude and opp heading. Made climbing right turn and the large transport passed under the small transport. Later learned the large transport was being vectored by mia approach control. Suggest mia not vector such aircraft so close to a high traffic density active AFB.
