HALO-II is an airborne observatory that offers excellent performance, adaptability, and endurance for its mission. The capability to fly at very high altitude, above obscuring clouds and atmosphere, provides the HALO-II sensors a clear view of mission targets. The EO/IR sensors are mounted in a pod on top of the fuselage, enabling excellent azimuth field of regard and horizon-to-horizon elevation viewing. HALO-II is modified, maintained, and operated by L-3 Aeromet.
