Raytheon JLENS | Info, Aerostats, Budget/Costs, Specs Networks with Navy CEC
In June 2012, a series of tests demonstrated that JLENS is capable of detecting and tracking multiple high-speed "swarming" boats from hundreds of miles away. In September 2012, during a joint Army and Navy test, a JLENS fire-control radar acquired and tracked a surrogate anti-ship cruise missile target. The tracking information was passed to sailors via the Cooperative Engagement Capability (CEC) sensor-netting system. The sailors then fired a Standard Missile SM-6 at the target. Initial SM-6 guidance used targeting information provided by the JLENS via CEC to the AEGIS BMD combat system until the missile's onboard radar was able to acquire and track the target.
EPIC - EPIC v. Army - Surveillance Blimps
On November 1, 2013, EPIC filed a FOIA request with the Department of the Army for records related to a blimp-mounted surveillance system called "JLENS" (Joint Land Attack Cruise Missile Defense Elevated Netted Sensor Systems). The JLENS system, manufactured by the defense contractor Raytheon, consists of a two-part system. The first part supports persistent, 360-degree radar-based surveillance over hundreds of miles. The other part is mounted with HELLFIRE missiles capable of firing at targets being tracked by the radar surveillance system. Raytheon describes JLENS as "two tethered, 74-meter helium-filled aerostats connected to mobile mooring stations and a communications and processing group. The aerostats fly as high as 10,000 feet above sea level and can remain aloft and operational for up to 30 days. One aerostat carries a surveillance radar with 360-degree surveillance capability; the other aerostat carries a fire control radar.”
Additionally, Raytheon has successfully tested JLENS' ability to support additional surveillance equipment in the form of a live video feed. JLENS operators can observe surface moving targets in real time using a Raytheon Company MTS-B Multi-Spectral Targeting System - a “long-range surveillance, target acquisition, tracking, range-finding and laser designation for the HELLFIRE missile and all tri-service and NATO laser-guided munitions."
The Army plans to test the surveillance capabilities of the JLENS system by surveilling the Washington, D.C. area for three years. The Army's test is scheduled to begin in the fall of 2014.
Joint Land Attack Cruise Missile Defense Elevated Netted Sensor [JLENS]
The Joint Land-Attack Cruise Missile Defense Elevated Netted Sensor
System (JLENS) consists of an aerostat with radars to provide
over-the-horizon surveillance for defense against cruise missiles. JLENS
is primarily intended to tackle the growing threat of cruise missiles to
US forces deployed abroad. The system enhances cruise missile detection
and engagement ranges with current air defense weapons such as PATRIOT,
Navy SM-2 missile, the Advanced Medium Range Air-to-Air Missile, and
ultimately the Medium Extended Air Defense System and the Corps
Surface-to-Air Missile System.CMDS JLENS Home
US Army places blimp-borne radar in strategic readiness
Should the U.S. or its allies need enhanced protection against cruise missiles, hostile airplanes, sea-borne threats or unmanned aircraft, military commanders will have a new system at their disposal. Raytheon Company (NYSE: RTN) has finished preparing a blimp-borne radar system previously used for testing, for use as a rapidly deployable strategic asset.
JLENS is a powerful airborne radar system that floats at altitudes as high as 10,000 feet, suspended from two 80-yard long, helium-filled blimp-like aerostats which are tethered to ground stations via a rugged cable. It helps defend critical assets, population centers and infrastructures against a variety of threats, such as manned- and unmanned- aircraft and missiles.
