ferry and transportation support; studies and surveys; United States
(U.S.) Government and contractor engineering, technical, and logistics
support services; and other related elements of logistics and program
support. The estimated total cost is $4.92 billion.
This proposed sale will support the foreign policy goals and
national security objectives of the U.S. by improving the security of a
major ally that is a force for political stability and economic
progress in the Indo-Pacific region.
This proposed sale will improve the Republic of Korea's ability to
meet current and future threats by providing increased intelligence,
surveillance, and reconnaissance (ISR) and airborne early warning and
control capabilities. It will also increase the ROK Air Force's
command, control, communications, computers, intelligence,
surveillance, and reconnaissance (C4ISR) interoperability with the U.S.
Korea will have no difficulty absorbing this equipment and support into
its armed forces.
The proposed sale of this equipment and support will not alter the
basic military balance in the region.
The principal contractor will be The Boeing Company, located in
Renton, WA. There are no known offset agreements proposed in connection
with this potential sale. Implementation of this proposed sale will not
require the assignment of any additional U.S. Government or contractor
representatives to the Republic of Korea.
There will be no adverse impact on U.S. defense readiness as a
result of this proposed sale.
Transmittal No. 24-99
Notice of Proposed Issuance of Letter of Offer Pursuant to Section
36(b)(1) of the Arms Export Control Act
Annex
Item No. vii
(vii) Sensitivity of Technology:
1. The E-7A Airborne Early Warning & Control (AEW&C) aircraft
provides advanced airborne moving target indication and battle
management, command and control capabilities, and advanced multi-role
electronically scanned array radar that enhances airborne battle
management and enables long-range kill chains.
2. The AN/AAQ-24(V)N Large Aircraft Infrared Countermeasures
(LAIRCM) system is a self- contained, directed-energy countermeasures
system designed to protect aircraft from infrared- guided surface-to-
air missiles. The LAIRCM system features digital technology micro-
miniature solid-state electronics. The system operates in all
conditions, detecting incoming missiles and jamming infrared-seeker
equipped missiles with aimed bursts of laser energy. The LAIRCM system
consists of multiple infrared missile warning sensors, the Guardian
Laser Transmitter Assembly (GLTA), a LAIRCM System Processor
Replacement (LSPR), a Control Interface Unit Replacement (CIUR), and a
classified memory card user data module (UDM).
a. LAIRCM's IR missile warning sensors detect and declare threat
missiles. The sensors are mounted on the aircraft exterior to provide
omni-directional protection. The sensors detect missile rocket plumes
and send appropriate data signals to the LSPR.
b. The Guardian Laser Transmitter Assembly (GLTA) is a laser
transmitter subsystem designed to track the inbound threat missile and
point the laser jam source at the missile's seeker. The GLTA
automatically deploys the laser countermeasure.
c. The LSPR analyzes the data from each missile warning sensor and
automatically deploys appropriate countermeasures via the GLTA. The
LSPR contains built-in-test (BIT) circuitry.
d. The CIUR displays the incoming threat for the pilot to take
appropriate action. The CIUR also provides an interface to program the
LAIRCM system to initiate BIT, display system status, and provide the
crew with bearing to threat missile launch.
e. The UDM card contains the laser jam codes. It is loaded into the
LSPR prior to flight; when not in use, the classified memory card user
data module is removed from the LSPR and put in secure storage.
3. The Embedded Global Positioning System/Inertial Navigation
System (GPS/INS) (EGI) with Selective Availability Anti-Spoofing Module
(SAASM)--or M-Code receiver when available and Precise Positioning
Service (PPS) is a self-contained navigation system that provides the
following: acceleration, velocity, position, attitude, platform
azimuth, magnetic and true heading, altitude, body angular rates, time
tags, and
[[Page 1518]]
coordinated universal time (UTC) synchronized time. SAASM or M-Code
enables the GPS receiver access to the encrypted P (Y or M) signal,
providing protection against active spoofing attacks.
4. The Multifunctional Information Distribution System Joint
Tactical Radio System (MIDS JTRS) provides an advanced Link-16 command,
control, communications, and intelligence (C3I) system incorporating
high-capacity and jam-resistant digital communications links for
exchange of near real-time tactical information, including both data
and voice, among air, ground, and sea elements.
5. The KIV-77 is a cryptographic appliqu[eacute] for identification
friend or foe (IFF). It can be loaded with Mode 5 classified elements.
6. The KY-100M is a cryptographic modernized lightweight terminal
for secure voice and data communications. The KY-100M provides wideband
and narrowband half-duplex communication. Operating in tactical ground,
marine and airborne applications, the KY-100M enables secure
communication with a broad range of radio and satellite equipment.
7. The AN/PYQ-10 Simple Key Loader is a portable, hand-held device
used for securely receiving, storing, and transferring data between
compatible cryptographic and communications equipment.
8. The AN/APX-119 is an IFF transponder that provides military
aircraft with a secure combat identification capability to help reduce
fratricide and enhance battlespace awareness, while providing safe
access to civilian airspace.
9. The AN/ARC-210 is a voice communications radio system equipped
with HAVEQUICK II, which employ cryptographic technology. Other
waveforms may be included as needed.
10. The highest level of classification of defense articles,
components, and services included in this potential sale is SECRET.
11. If a technologically advanced adversary were to obtain
knowledge of the specific hardware and software elements, the
information could be used to develop countermeasures that might reduce
weapon system effectiveness or be used in the development of a system
with similar or advanced capabilities.
12. A determination has been made that the Republic of Korea can
provide substantially the same degree of protection for the sensitive
technology being released as the U.S. Government. This sale is
necessary in furtherance of the U.S. foreign policy and national
security objectives outlined in the Policy Justification.
13. All defense articles and services listed in this transmittal
have been authorized for release and export to the Republic of Korea.
