    This proposed sale will support the foreign policy goals and 
national security objectives of the United States by improving the 
security of a major ally that is a force for political stability and 
economic progress in the Indo-Pacific region.
    The proposed sale will improve the Republic of Korea's capability 
to meet current and future threats by providing a credible force 
capable of deterring adversaries and participating in regional 
operations. Korea will have no difficulty absorbing this equipment into 
its armed forces.
    The proposed sale of this equipment and support will not alter the 
basic military balance in the region.
    The principal contractors will be Boeing, located in Mesa, AZ; and 
Lockheed Martin, located in Orlando, FL. The purchaser typically 
requests offsets. Any offset agreement will be defined in negotiations 
between the purchaser and the contractor.
    There will be no adverse impact on U.S. defense readiness as a 
result of this proposed sale.
Transmittal No. 24-36
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 AH-64E Apache Attack Helicopter is the Army's advanced 
attack helicopter, equipped for performing close air support, anti-
armor, and armed reconnaissance missions. The aircraft contains the 
following communications and target identification equipment, 
navigation equipment, aircraft survivability equipment, displays, and 
sensors:
    a. The AN/ASQ-170 Modernized Target Acquisition and Designation 
Sight/AN/AAQ-11 Pilot Night Vision Sensor (MTADS/PNVS) provides day, 
night, and limited adverse weather target information, as well as night 
navigation capabilities. The PNVS provides thermal imaging that permits 
nap-of-the-earth flight to, from, and within the battle area, while 
MTADS provides the copilot gunner with search, detection, recognition, 
and designation capabilities by means of Direct View Optics (DVO), 
television, and Forward Looking Infrared (FLIR) sighting systems that 
may be used singularly or in combinations.
    b. The AN/APG-78 Fire Control Radar (FCR) is an active, low-
probability of intercept, millimeter-wave radar, combined with a 
passive AN/APR-48B Modernized Radar Frequency Interferometer (M-RFI) 
mounted on top of the helicopter mast. The FCR Ground Targeting Mode 
detects, locates, classifies and prioritizes stationary or moving 
armored vehicles, tanks and mobile air defense systems as well as 
hovering helicopters, helicopters in flight, and fixed wing aircraft in 
normal flight. If desired, the radar data can be used to refer targets 
to the regular electro-optical Modernized Target Acquisition and 
Designation Sight (MTADS).
    c. The AN/APR-48B Modernized Radar Frequency Interferometer (M-RFI) 
is an updated version of the passive radar detection and direction 
finding system. It utilizes a detachable User Data Module (UDM) on the 
M-RFI processor, which contains the Radar Frequency (RF) threat 
library.
    d. The AGM-114R Hellfire is a semi-active laser guided missile with 
a multi-purpose warhead that can engage and defeat both high and 
heavily armored targets, personnel, bunkers, caves, and urban 
structures.
    e. The JAGM-179A is an Air-to-Ground Missile (AGM) consisting of 
the Hellfire Romeo (AGM-114R) back-end (i.e., propulsion, warhead, and 
control sections) mated to a newly designed dual-mode guidance section 
(GS). The dual-mode GS is a combination of Millimeter Wave (MMW) and 
Semi-Active Laser (SAL) sensors co-axially aligned on a steerable 
gimbal. The combination of MMW and SAL sensors provide improved 
Precision Point (PP) and Fire-and-Forget (FF) capabilities in a single 
munition. This combination allows for targeting of fast moving and 
stationary targets in countermeasure and intensive battlefield 
environments, and in low cloud ceiling and adverse weather. Firing 
modes include Lock-On Before Launch (LOBL) and Lock-On After Launch 
(LOAL). Engagement modes include Point Designation (PD)--SAL only, 
Target Designation (PD)--SAL initiated with MMW engagement completion, 
Active Fire & Forget/Laser

[[Page 51688]]

Queuing (AFF-LQ)--MMW initiated with SAL override capability, and 
Active Fire & Forget (AFF)-MMW only. Hosting platforms include select 
rotary-wing and fixed-wing aircraft, wheeled or tracked vehicles, 
ground-based pedestal launchers, and patrol boats. Targets include 
tactical armor, boats, bunkers, buildings, caves, personnel in the 
open, rotary-wing and slow fixed-wing aircraft, UAS, and fast-moving 
non-tactical vehicles. The MMW is capable of hitting low radar cross 
section targets.
    f. The AAR-57 Common Missile Warning System (CMWS) detects energy 
emitted by threat missiles in-flight, evaluates potential false alarm 
emitters in the environment, declares validity of threats, and selects 
appropriate countermeasures for defeat. The CMWS consists of an 
Electronic Control Unit (ECU), Electro-Optic Missile Sensors (EOMSs), 
and Sequencer and Improved Countermeasures Dispenser (ICMD).
    g. The AN/APR-39 Radar Warning Receiver Signal Detecting Set is a 
system that provides warning of a radar-directed air defense threat and 
allows for the employment of appropriate countermeasures. This is the 
1553 data bus compatible configuration.
    h. The Hellfire M36E8 Captive Air Training Missile (CATM) is a 
flight-training missile that consists of a functional guidance section 
coupled to an inert missile bus. It functions like a tactical missile 
during captive carry on the aircraft, absent launch capability, making 
it suitable for training the aircrew in simulated Hellfire Missile 
target acquisition and lock.
    i. The AH-64E uses two EAGLE+MMR Embedded Global Positioning System 
(GPS)/Inertial Navigation Systems (INS) (EGI) with Multi-Mode Receiver. 
The EAGLE+MMR is a self-contained, all-attitude navigation system with 
an embedded GPS receiver controlled via MIL-STD-1553B controller, and 
provides output navigation and GPS timing data to support ADS-B out and 
other platform systems. The EAGLE EGI unit houses a 24 channel GPS 
receiver capable of operating in either Standard Positioning Service 
(SPS) C/A-code (non-encrypted) or Precise Positioning Service (PPS) Y-
code (encrypted).
    2. The highest level of classification of defense articles, 
components, and services included in this potential sale is SECRET.
    3. 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.
    4. 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.
    5. All defense articles and services listed in this transmittal 
have been authorized for release and export to the Republic of Korea.
