Annex
Item No. vii
    (vii) Sensitivity of Technology:
    1. The UH-60M aircraft is a medium lift four bladed aircraft which 
includes two (2) T-701D engines. The aircraft has four (4) 
Multifunction Displays (MFD), which provides aircraft system, flight, 
mission, and communication management systems. The instrumentation 
panel includes four (4) Multifunction Displays (MFDs), two (2) Pilot 
and Co-Pilot Flight Director Panels, and two (2) Data Concentrator 
Units (DCUs). The Navigation System will have Embedded Global 
Positioning System (GPS)/Inertial Navigation System (INS) (EGIs), and 
two (2) Advanced Flight Control Computer Systems (AFCC), which provide 
4 axis aircraft control:
    a. The AN/ARC-201 very high frequency (VHF)--frequency modulation 
(FM) (VHF-FM) Single Channel Ground and Airborne Radio System 
(SINCGARS) is a reliable, field-proven voice and data communication 
system used with the UH-60. A non-communications security (COMSEC) 
export variant of this radio that meets these requirements will be 
provided.
    b. AN/ARC-231 RT-1808A (or future replacement) VHF/UHF/LOS 
satellite communications (SATCOM) Radios. The AN/ARC-231 is a software-
definable radio for military aircraft that provides two-way, multi-mode 
voice and data communications over a 30 Hz to 512 MHz frequency range. 
It covers both line-of-sight ultra-high frequency (UHF) and VHF bands 
with amplitude modulation (AM), FM, and SATCOM capabilities.
    c. The AN/ARC-231A is a software-definable radio for military 
aircraft that provides two-way, multi-mode voice and data 
communications over a 30 Hz to 512 MHz frequency range. No designated 
exportable, non-COMSEC capable version is planned. The AN/ARC-231A 
supports both line-of-sight UHF and VHF bands with AM, FM, and SATCOM 
capabilities. It also includes embedded frequency agile modes, 
Electronic Counter-Countermeasures (ECCM), anti-jam waveforms including 
Have Quick and Single Channel Ground and Airborne Radio System 
(SINCGARS), Demand Assigned Multiple Access (DAMA), and Integrated 
Waveform (IW). It provides simultaneous, real-time participation in 
tactical voice and data communications networks. The RT-1987 will 
provide National Security Agency (NSA) Tactical Secure Voice 
Cryptographic Interoperability Specification (TSVCIS) 3.1.1 crypto 
modernization compliance. Operator selectable air traffic control 
channel spacing of 5, 8.33, 12.5, and 25 kHz steps, and other data link 
and secure communications features, provide battlefield 
interoperability.
    d. The AN/ARC-210 is a family of radios for military aircraft that 
provides two-way, multi-mode voice and data communications over a 30 to 
512+ MHz frequency range. It covers both UHF and VHF bands with AM, FM, 
and SATCOM capabilities. The ARC-210 radio also includes embedded anti-
jam waveforms, including Have Quick and SINCGARS, and other data link 
and secure communications features, providing total battlefield 
interoperability and high-performance capabilities in the transfer of 
data, voice, and imagery. The software-programmable encryption is under 
the NSA Cryptographic Modernization Initiative.
    e. The AN/ARC-220 High Frequency (HF) Airborne Communication System 
provides rotary-wing aircraft with advanced voice and data capabilities 
for short-and long-distance communications. The system is software 
programmable with a frequency range of 2.0000-29.9999 MHz, in 100 Hz 
steps and provides for providing embedded automatic Link establishment 
(ALE), serial tone data modem, text messaging, GPS position reporting, 
and anti-jam (ECCM) functions.
    f. The AN/APX-123A (or future replacement) Identification Friend or 
Foe (IFF) Transponder is a space diversity transponder and is installed 
on various military platforms. When installed in conjunction with 
platform antennas and the remote-control unit (or other appropriate 
control unit), the transponder provides identification, altitude, and 
surveillance reporting in response to interrogations from airborne, 
ground-based, and surface interrogators. The transponder will be 
classified SECRET if MODE IV, MODE 5, or MODE S fill is installed in 
the equipment with a crypto device. This item contains sensitive 
technology.
    g. The VRC-100 HF Communication System is the ground station 
version of the AN/ARC-220 for use in Aviation Operation Centers. It 
provides for advanced voice and data capabilities for short-and long-
distance communications. The system is software programmable with a 
frequency range of 2.0000-29.9999 MHz in 100 Hz steps and provides 
embedded Automatic Link Establishment (ALE), serial tone data modem, 
text messaging, GPS position reporting, and anti-jam (ECCM) functions. 
The system is purchased with all required mounts, amplifiers, antennas, 
power supplies, and accessories.
    h. The AN/PYQ-10 Simple Key Loader (SKL) is a ruggedized, portable, 
hand-held fill device for securely receiving, storing, and transferring 
data between compatible cryptographic and communications equipment. The 
AN/PYQ-10(C) Simple Key Loader (SKL) will contain the KOV-21 COMSEC 
card, which is a Controlled Cryptographic Item (CCI). Cryptographic 
functions are performed by an embedded KOV-21 card developed by the 
NSA.
    i. The KIV-77 Identification Friend or Foe (IFF) Crypto Applique 
provides cryptographic and time-of-day services for a Combined 
Interrogator/Transponder (CIT) or individual interrogator or 
transponder Mark XIIA (Mode 4 and Mode 5) IFF system deployed to 
identify cooperative, friendly systems. The KIV-77 contains embedded 
security, and when keys are loaded is classified up to Secret.
    j. The KY-100M is a self-contained terminal including COMSEC that 
provides for secure voice and data communications in tactical airborne 
and ground environments. It is an integral part of U.S. Forces' and 
Federal law enforcement agencies' networks and provides half-duplex, 
narrowband, and wideband communications. Its flexible interfaces 
increase compatibility with a wide range of voice, data, radio, and 
satellite equipment. The KY can support Tier 1 crypto.
    k. The AN/APR-39C(V)1/4 Radar Warning System detects radar-based 
rangefinders, target designators, and beam rider systems targeting an 
aircraft or vehicle. The APR-39 is a detection component of the suite 
of countermeasures designed to increase survivability of current 
generation combat aircraft and specialized special operations aircraft 
against the threat posed by laser designated or guided weapons. This 
item contains sensitive technology.
    l. The AN/AVR-2B Laser Warning Receiver detects laser rangefinders, 
target designators, and beam rider laser-aided systems targeting an 
aircraft or vehicle. The AVR-2B is a detection component of the suite 
of countermeasures designed to increase survivability of current 
generation combat aircraft and specialized special operations aircraft 
against the threat

[[Page 620]]

posed by laser designated or guided weapons. This item contains 
sensitive technology.
    m. The AAR-57 Common Missile Warning System (CMWS) is an integrated 
infrared (IR) countermeasures suite utilizing ultraviolet (UV) sensors 
to display accurate threat location and dispense countermeasures either 
automatically or under pilot or crew control to defeat incoming missile 
threats.
    n. Embedded GPS/Inertial Navigation System INS (EGI) provides GPS 
and INS capabilities to the aircraft. The EGI will include Selective 
Availability Anti-Spoofing Module (SAASM) security modules to be used 
for secure GPS Precise Positioning Service (PPS) if required. The 
Embedded GPS/INS within the SAASM contains sensitive technology.
    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 Croatia 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 are 
authorized for release and export to Croatia.
