HANSCOM AFB, Mass. - Bruce Wilbur of Northrop Grumman Corp. installs operator workstation interface equipment on a Joint STARS jet at Robins AFB, Ga., this week. The 751st Electronic Systems Group is managing the comprehensive upgrade, which will make beyond-line-of-sight communication possible, allowing Joint STARS to stand off further from fixed or mobile ground stations and increasing their range and coverage capabilities.
