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.
