HALE UAV
A High-Altitude Long-Endurance Unmanned Aerial Vehicle (UAV), or drone, is an aircraft designed to fly at very high altitudes for extended periods, typically for surveillance, reconnaissance, or communication purposes.

TECHNICAL DEFINITION
HALE UAVs (High-Altitude Long-Endurance Unmanned Aerial Vehicles) are a category of unmanned aircraft systems engineered for persistent intelligence, surveillance, and reconnaissance (ISR) and communications relay missions, capable of operating autonomously at stratospheric altitudes (60,000+ feet) for durations exceeding 24 hours.
BACKGROUND
Boeing Defense, Space & Security (BDS) is a division of the Boeing Company based in Saint Louis, Missouri. The division builds military airplanes, rotorcraft, and missiles, as well as space systems for both commercial and military customers, including satellites, spacecraft, and rockets.
