2 Proliferation is Massive The Threat Source: Bart Elias, Congressional Research Service, 2 Dec 03 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”

3 The Warfighter Needs Protection … Protect The Warfighter From MANPADS & Air-to-Air Missiles AH-1W Super Cobra Fires on Iraqi positions in S. Iraq Current jammers can’t do the job: – costly, heavy & bulky The Need US Black Hawk Helicopter crashes near Tikrit in Iraq, six marines dead (Nov ’03) UH-60 Blackhawk over Iraq

4 The Need 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 Commercial Airlines Need Protection…….. A Reliable Low-Cost Aircraft Protection System is Needed Now Source: RAND Report, Jan 05

5 Programs Overview The Shout for Affordable Aircraft Self-Protection is Loud & Clear Scorpion Low Cost Aircraft Protection System Quiet Eyes Low Cost DIRCM Micro-Turret Very low cost, low weight, small size Leverages production systems to achieve high reliability Meets full coverage & performance requirements Laser Controller Pointer Controller Pointer Laser MW Sensor “The Incumbents can’t get on the small helos” “Cost, weight, reliability are big issues for existing systems” Navy: Rapid Technology Transition Program OSD & Air Force: Defense Acquisition Challenge Program

6 How It Works Laser-based Infrared Countermeasures (IRCM) 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 Jamming Laser Missile Warning Coverage

7 Already in production Very low cost Proven reliability Small size & weight AIM-9X Pointer Pointer Based on Production AIM-9X Missile

8 Pointer Optical Components Pod 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 Lenses Laser Dome Pointer Optics are Critical Components of Aircraft Protection Sytems

9 Thermal Radiation from Missile Laser Beam from Pointer Missile Summary of the Aircraft Protection System Incoming missile heats up and emits infrared light (Thermal radiation) Telescope detects and tracks thermal radiation of incoming missile Pointer Telescope 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 Pointer

10 Multi-band IR LaserMissile Warning Sensors 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. Missile Warning Sensors and Multi-band Laser also Mature 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 & Laser

11 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 Summary Affordable, Reliable Aircraft Self-Protection
