Northrop Leads U. S. Production Of Airborne Jamming Equipment

Rolling Meadows, 111.—Northrop’s Defense Systems Div. has emerged as the nation’s largest producer of airborne jamming equipment, with 1986 sales of $450 million, nearly three times its output in 1980. More modest growth is projected for 1987, according to W. C. Solberg, division general manager.

Raytheon Broadens Application Of Rotman Lens Technology

Goleta, Calif.—Raytheon’s Electromagnetic Systems Div. here is developing two key aspects of electronic warfare—listening for enemy signals and active jamming of those signals. Much of the division’s current product line and future plans exploit the Rotman lens, a type of antenna array that can simultaneously monitor and find the direction to a number of signals, or simultaneously jam on several bearings (AW&ST Apr. 14, 1986, p. 95). However, Raytheon ESD also is looking at other technologies appropriate for its future systems, such as interferometer antennas to improve direction-finding resolution.

Soviet Long-Duration Crew Activates Mir Space Station

Washington—The Soviet Union last week began a long-duration mission on the Mir space station with a cosmonaut crew that will use extravehicular activity and large modules launched from Earth to expand the facility. The new flight directly supports the Soviet Union’s key space goal—establishment of a permanently manned station that will be enlarged substantially to expand military, scientific and space applications and enhance the prestige of the USSR.
