SALT LAKE CITY, Jan. 14, 2013 /PRNewswire/ --A recent demonstration proved
that operators can observe surface moving targets -- including a terrorist
role-player planting an improvised explosive device -- in real time using a
Raytheon Company (NYSE: RTN) MTS-B Multi-Spectral Targeting Systemmounted on
the JLENS.

During the Raytheon-funded demonstration, and despite heavy smoke from recent,
naturally-occurring forest fires, an MTS-B electro-optical/infrared (EO/IR)
sensor mounted on a JLENS surveillance aerostat tracked numerous targets with
the IR sensor. Video from the MTS-B was passed through the aerostat's tether,
enabling operators to watch live feed of trucks, trains and cars from dozens
of miles away. While the MTS-B visually tracked targets, the JLENS
simultaneously tracked surface targets with its integrated radar system,
demonstrating the potential to integrate the JLENS radar and EO/IR payloads.

As part of the demonstration, operators also used the MTS-B's EO sensor to
watch Raytheon employees simulate planting a roadside improvised explosive

"The JLENS integrated fire-control radar and 360-degree surveillance radar
already gives the warfighter the capability to detect and engage surface and
airborne threats like swarming boats and anti-ship cruise missiles," said Dave
Gulla, vice president of Global Integrated Sensors for Raytheon's Integrated
Defense Systems business. "Integrating the proven MTS-B on JLENS makes JLENS
multi-mission capable and enables the warfighter to better defend the
battlespace and protect critical infrastructure and waterways."

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, mobile missile launchers, automobiles, trucks
and tanks. JLENS also provides ascent phase detection of tactical ballistic
missiles and large-caliber rockets.

  oA JLENS system, referred to as an orbit, consists of two tethered,
    74-meter aerostats connected to mobile mooring stations and communications
    and processing groups.
  oThe aerostats fly as high as 10,000 feet, can remain aloft and operational
    for up to 30 days, and can detect and target threats up to 550 km (340
    statute miles) away.
  oOne aerostat carries a 360-degree surveillance radar, while the other
    carries a fire control radar.

Note to Editors
Real time video from the MTS-B was passedvia fiber-optic cable the entire
length of the aerostat, and 10,000 feet down the length of the tether into an
MTS-B ground control station.
