NYTimes reports today that the F-35s in Puerto Rico are based at the old, closed (2004) Roosevelt Roads NAS at the eastern end of the island, as reported previously. They also report that the MQ-9 Reaper drones are now based at the Rafael Hernández Airport in Aguadilla (BQN) near the NW tip of the island. I used to visit there in the 1970s, but I've not heard of any military operations from it until this report. The Times has an aerial photo of what appears to be ammunition storage bunkers recently built there.
