Description:
The Joint Land Attack Cruise Missile Defense Elevated Netted Senor System (JLENS) is a tactical, theater based, advanced sensor system. The system is elevated by tethered aerostats to increase battlefield area coverage against land attack cruise missiles and to provide detection of enemy surface units. Te JLENS aerostats could be on station during up to 30 days, providing over-the-horizon detection, tracking and targeting capability against attack missiles. JLENS' secondary missions are: combat identification, communication relays and attack operations.
The JLENS consists of a tethered aerostat, a long range, IFF-capable, surveillance radar and a track and illumination radar. The electrical power is supplied to the aerostat by ground stations through the tether. It is being developed to support air defense systems based upon the AMRAAM, Patriot and Standard missiles.
On December 16, 2004, Raytheon was awarded a $770 million increment as part of a previous $1.3 billion contract awarded on December 29, 2003, for two complete JLENS systems less surveillance radar. The US Army is the contracting activity, the work will be performed at Raytheon facilities at Bedford, Massachusetts, and the two systems less surveillance radar will be completed by July 31, 2010.
In November 2005 Raytheon received a $1.3 billion contract for JLENS development and demonstration from the US Army. Under the new contract testing on JLENS was planned to begin in 2009 and program completion two years later, in 2011.
