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”

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
The Need
Commercial Airlines Need
Protection……..
•
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 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
2• Pointer is directed onto, and
tracks, the missile

jams the missile seeker
4• Laser jamming causes the
missile to miss
Laser-based Infrared Countermeasures (IRCM)
AIM-9X Pointer
Sidewinder
AIM-9X
• 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)
• Design works with a variety of mid
IR laser technologies
• Raytheon produces robust 1-color
sensors currently flying on F16Is
• Raytheon working with Aculight on
both Navy (Scorpion) & Air Force
Defense Acquisition Challenge
program (Quiet Eyes)
• Navy Scorpion program upgrades
production 1-color sensors to
2-color.

• 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
