The High-Altitude Long-Endurance Demonstrator (HALE-D) was a science and technology development effort that was part of the Army’s High Altitude Airship (HAA) Advanced Concept Technology Demonstration (ACTD) program, which also included the HiSentinel family of airships. The long-term goal of the HAA program was to develop the full-scale HAA.

Driven by two electric propulsion motors, the HALE-D validated several key technologies including a solar-based regenerative power system, advanced hull materials, and a unique trim system, all while demonstrating safe operations of an unmanned LTA system in national air space.
