JLENS proves ability to defend congested vital waterways

SALT LAKE CITY, Dec. 5, 2012 /PRNewswire/ --Swarming boats operating in
highly-trafficked strategic waterways will soon be easier to detect, target
and engage. During a recent test, a Raytheon Company (NYSE: RTN) JLENS
simultaneously detected and tracked double-digit swarming boats, hundreds of
cars and trucks, non-swarming boats and manned and unmanned aircraft.

The swarming boats, similar to swarming boats in the inventories of hostile
navies in high-threat regions of the globe, simulated a real-world scenario
with a series of tactical maneuvers at low and high speeds. The aircraft and
other vehicles JLENS tracked were similar to the other kinds of systems that
might operate in the vicinity of busy vital waterways.

"This test proved JLENS can help keep important chokepoints free from the
growing threat of swarming boats by detecting them from hundreds of miles away
in a congested environment, enabling commanders to take appropriate action,"
said David Gulla, vice president of Global Integrated Sensors for Raytheon's
Integrated Defense Systems business. "This success, which comes on the heels
of a JLENS-enabled intercept of an anti-ship cruise missile, demonstrates that
JLENS is ready to deploy for a Combatant Commander operational evaluation."

JLENS, an elevated, persistent over-the-horizon sensor system, uses a powerful
integrated radar system to detect, track and target a variety of threats. This
capability better enables commanders to defend against threats, including
hostile cruise missiles, low-flying manned and unmanned aircraft, and moving
surface vehicles such as boats, automobiles and trucks; and provide ascent
phase detection of tactical ballistic missiles and large caliber rockets.

"JLENS' 360-degree long-range surveillance capability expands the battlepsace
because JLENS can simultaneously detect and engage threats like swarming boats
and anti-ship cruise missiles from up to 340 miles away," said Dean Barten,
the U.S. Army's JLENS program manager.


  oA JLENS system, referred to as an orbit, consists of two tethered,
    74-meter aerostats connected to mobile mooring stations and a
    communications and processing group.
  oThe aerostats fly as high as 10,000 feet and can remain aloft and
    operational for up to 30 days.
  oOne aerostat carries surveillance radar with 360-degree surveillance
    capability; the other aerostat carries a fire control radar.
  oAccording to research conducted by the U.S. Army's JLENS Product office,
    the cost of operating large, fixed-wing surveillance aircraft is 5-7 times
    greater than the cost of operating JLENS.
  oThe JLENS surveillance radar can simultaneously track hundreds of threats;
    the fire control radar can simultaneously target dozens of threats.
