Global Hawk, Northrop Grumman’s sophisticated unmanned high altitude surveillance aircraft is finding its niche in unexpected areas. In April, 2010, in consort with NASA, a Global Hawk fitted with scientific instruments completed 82.5 flight hours cruising at latitudes ranging from the Arctic Circle to just near the equator as part of an ongoing civilian research program known as GloPac, or Global Hawk Pacific Program, which aims to study atmospheric conditions over the Pacific and Arctic oceans.
