and Identification Friend or Foe (IFF) modes1, 2, and 3 were successfully executed.JLENS successfully completed 22 of 23(96%) DT-1 missions from 07 November2011 to 16 December 2011. The JLENSradars successfully tracked fighter aircraftand towed targets and cruise missile targets,meeting accuracy requirements withinmargin. The formal testing demonstratedsuccessful IFF using several detectionmodes (1–3). JLENS tracks weresuccessfully integrated into the Hill AirForce base Link-16 network and a localnetwork that included counter-rocket,artillery and mortar forward area air defensecommand and control as well as sentinelradars. Target handovers were executed to atactical Patriot radar system via Link-16. Inbetween periods of formal testing, testingwas conducted to progress non-cooperativetarget recognition, IFF Mode 4, unmannedaerial vehicle (UAV) and surface-movingtarget tracking capabilities. Thisaccomplishment provided data to conduct ofan IFC mission with a Patriot AdvancedCapabilities-3 (PAC-3) missile in April2012. 21The program incurred a significant Nunn-McCurdy cost and schedule breach in 2011.The breach was due to a 2010 decision toextend the program 6 months as part of theArmy’s overall strategy for integrated airand missile defense. Engineering challengesassociated with prime item integration anddelays to developmental testing caused bythe destruction of a prototype aerostat duringsevere weather at the contractor’smanufacturing facility further contributed tothe delay. As a result of the 6-month delay,the program acquisition unit cost exceeded15% (17.88%), which triggered the breach. 21The JLENS Product Office and the LowerTier Project Office recently conducted asuccessful detect, track and shoot down of alow flying, long-range drone target at theUTTR on 25 April 2012. This demonstratedthe unique ability to detect, track, engageand destroy a cruise missile target atextended range in an integrated air andmissile defense architecture that joins nettedsensors and missile defense systems. 21Plans for FY12 include completing softwaredevelopment/integration/testing andcontinuing DT, including a PAC-3 IFCmission. The Army will complete theJLENS EMD program to complete testingand maintain a viable option to beginprocurement at milestone (MS) C. On-goingstudy and analysis could potentially result inJLENS participation in an operationalassessment in support of a CombatantCommand (COCOM) Exercise in the nearterm.20
