The Threat • Military Inventories estimate • 350K – 500K missiles • Non-State Actors • 25-30 groups (IRA, FARC, Hezbollah, PKK) • 5-150K missiles • Reported IR missiles • Stinger (USA) • SA-7, SA-14/16/18 (Russia) • HN-5/QW-1 (China) • Reports of Missiles in Circulation • “5,592 missiles captured in Afghanistan as of December 2002” • “4-5K available to Iraqi insurgents” Source: Bart Elias, Congressional Research Service, 2 Dec 03 Proliferation is Massive
The Need The Warfighter Needs Protection … Current jammers can’t do the job: – costly, heavy & bulky AH-1W Super Cobra Fires on Iraqi positions in S. Iraq UH-60 Blackhawk over Iraq US Black Hawk Helicopter crashes near Tikrit in Iraq, six marines dead (Nov ’03) Protect The Warfighter From MANPADS & Air-to-Air Missiles
Manpads will unavoidably become more attractive to terrorists 2002 attempt to bring down Israeli airliner at Mambosa, Kenya Deploying antimissile defenses on planes is too expensive now Equipping 6,800 commercial jets would cost $11B Annual operating costs would be $2.1B Total federal spending on all transportation security is ~$4.4B The Need Commercial Airlines Need Protection……..

Programs Overview ScorpionLow Cost Aircraft Protection System Quiet EyesLow Cost DIRCM Micro-Turret Navy: Rapid Technology Transition Program OSD & Air Force: Defense Acquisition Challenge Program Controller Pointer Controller Pointer Laser Laser MW Sensor “The Incumbents can’t get on the small helos” “Cost, weight, reliability are big issues for existing systems” • Very low cost, low weight, small size • Leverages production systems to achieve high reliability • Meets full coverage & performance requirements The Shout for Affordable Aircraft Self-Protection is Loud & Clear
How It Works 1 • Missile launch is detected by missile warning sensors • Pointer is directed onto, and tracks, the missile • A low power infrared laser jams the missile seeker • Laser jamming causes the missile to miss 2 1 2 Missile Warning Coverage 3 3 Jamming Laser 4 4 Laser-based Infrared Countermeasures (IRCM)
AIM-9X Pointer • Already in production • Very low cost • Proven reliability • Small size & weight AIM-9X Pointer Pointer Based on Production AIM-9X Missile
Pointer Optical Components Pointer Dome Pod Lenses Laser • Telescope: Dome, lenses, mirrors, prisms • Collects infrared light emitted by incoming missile • Detector: An array of semiconductor material sensitive to infrared light • Converts incident light into electronic signals • Laser: High intensity light source • Confuses incoming missile’s detector Optics are Critical Components of Aircraft Protection Sytems
Summary of the Aircraft Protection System Pointer Thermal Radiation from Missile Missile Laser Beam from Pointer Pointer Telescope • Incoming missile heats up and emits infrared light (Thermal radiation) • Telescope detects and tracks thermal radiation of incoming missile Pointer Laser • Laser wavelength must match incoming missile’s operational wavelength • Multi-band laser necessary to protect from various threats: • Stinger, SA-7, SA-14/16/18, HN-5/QW-1 • Laser is modulated to jam the incoming missile
Missile Warning Sensors & Laser Missile Warning Sensors Multi-band IR Laser • Design accommodates a variety of missile warning sensors (UV, IR) • Raytheon produces robust 1-color sensors currently flying on F16Is • Navy Scorpion program upgrades production 1-color sensors to 2-color. • Design works with a variety of mid IR laser technologies • Raytheon working with Aculight on both Navy (Scorpion) & Air Force Defense Acquisition Challenge program (Quiet Eyes) • All lasers are multi-band IR Missile Warning Sensors and Multi-band Laser also Mature
Summary • Optics are critical components of IRCM aircraft protections systems • Pointer telescope detects and tracks threats • Laser jams and confuses incoming missiles • Significant benefits compared with existing systems • Very Low Cost • Highly reliable • Small package • Multiple services pursuing capability • Navy: Protection for small helicopters • Air Force: Affordable pointer • Leverages proven systems to provide near term capability • AIM-9X pointer & Processor • Production missile warning sensors • Programs showing tremendous progress • Initial pointer demonstrations complete • System prototype demonstration scheduled for late 2006 Affordable, Reliable Aircraft Self-Protection
