According to the documents, CBP already appears to be flying drones well within the Southern and Northern US borders, and for a wide variety of non-border patrol reasons. What’s more — the agency is planning to increase its Predator drone fleet to 24 and its drone surveillance to 24 hours per day / 7 days per week by 2016.
As the Concept of Operations report notes, CBP’s goal is that its drone data will be “persistently available” (p. 21) and interoperable (p. 29) — not just within CBP, but to other agencies, and also possibly to other countries. CBP plans that its “UAS will provide assured monitoring of entities along land borders, inland seas, littorals and high seas with sufficient frequency, continuity, accuracy, spectral diversity, and data content to produce actionable information.
