POLICY JUSTIFICATION
Japan--Aegis Class Destroyer Support
The Government of Japan has requested to buy follow-on technical
support of Aegis class destroyers, including Combat Systems Sea
Qualification Trials (CSSQT); test and evaluation services; sustainment
support and services; Aegis computer software updates; systems
integration
[[Page 11533]]
and testing, in-country and on-site engineering support; all necessary
emergent engineering and technical support services; familiarization,
operational support; system overhauls; system upgrades; on-the-job
practical operations and maintenance; combat systems integration;
development, testing, and installation of program patches; adaptation
data and annual service agreements; fielding technical inquiries by the
purchaser; operational integration and maintenance support; field
service engineering; problem investigation; technical assistance;
support solutions to technical problems arising from post-production;
testing capabilities; supporting U.S. Government contractors and
technical engineers; and other related elements of logistics and
program support. The estimated total cost is $100.2 million.
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.
The proposed sale will improve Japan's capability to meet current
and future threats by ensuring Japan Maritime Self Defense Force's
(JMSDF) Aegis fleet remains ready to provide critical capabilities in
the defense of Japan. Specifically, the requested CSSQT services will
provide JSMDF with capability support that is vital to the effective
and safe operations of the Aegis Combat Systems (ACS) suite. Japan
continues to modernize its fleet to support Integrated Air and Missile
Defense (IAMD) roles and special mission requirements. The JMSDF Aegis
Fleet will fulfill Japan's mission goal of acquiring and maintaining
their Aegis capable ships and will further enhance interoperability
with the U.S. Navy, build upon a longstanding cooperative effort with
the U.S., and provide enhanced capability with a valued partner in a
geographic region of critical importance to Japan and the U.S.
Government. The Aegis destroyers in Japan's fleet afford greater
flexibility and capability to counter regional threats and to enhance
stability in the region. Japan currently operates Aegis ships, is
proficient at using their evolving ballistic missile defense
capability, and is effective at employing the AN/SQQ-89A(V)15J undersea
warfare combat system for undersea surveillance and detection. Japan
will have no difficulty absorbing these services 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 Lockheed Martin Corporation,
located in Moorestown, NJ. At this time, the U.S. Government is not
aware of any offset agreement proposed in connection with this
potential sale. Any offset agreement will be defined in negotiations
between the purchaser and the contractor.
Implementation of this proposed sale will not require the
assignment of any additional U.S. Government or contractor
representatives to Japan.
There will be no adverse impact on U.S. defense readiness as a
result of this proposed sale.
Transmittal No. 26-10
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 Aegis Weapon System (AWS) is a multi-mission combat system
providing Integrated Air and Missile Defense (IAMD) for surface ships.
The follow-on technical support includes Combat System Ship
Qualification Trials (CSSQT) test and evaluation (T&E) services, and
software in support of AWS Baseline 9 with integrated Ballistic Missile
Defense (BMD).
2. The CSSQT services for Japan's Aegis System Equipped Vessels
(ASEV) are critical to ensuring that the Japan Maritime Self Defense
Force's (JMSDF) Aegis destroyer fleet remains ready to provide critical
capabilities in the defense of Japan. Specifically, the requested CSSQT
services provide the JMSDF with capability support vital to the
effective and safe operations of the Aegis Combat Systems (ACS) suite.
3. The Aegis CSSQT services facilitate Japan's MSDF's multi-mission
Aegis destroyers' ability to meet readiness and operational
requirements to include Ballistic Missile Defense, Air Defense Warfare
(ADW), surface warfare (SUW), Naval Gun Fire Support (NGFS), Anti-
Submarine Warfare (ASW), and electronic warfare (EW) missions. CSSQT
includes in-port assessment of shipboard systems, Waterfront
Integration Testing (WIT), CSSQT-specific training, and installation of
telemetry and support equipment. It also includes at-sea support of the
range, target launch/recovery, and boat and aircraft services at Oahu
Operation Area and Pacific Missile Range Facility (PMRF) in Kauai,
Hawaii.
4. The at-sea CSSQT events provide tracking and live-fire events of
ADW, including IAMD, SUW, Undersea Warfare (USW), EW, and Command,
Control, and Communications (CCC).
5. After completing CSSQT events, the USN will analyze data and
deliver a final report to document system performance during CSSQT. ADW
live fire events will use Standard Missile SM-2, SM-6, and Enhanced Sea
Sparrow Missile (ESSM) from JMSDF inventory. SUW and ASW live fire
events will use JMSDF inventory of gun ammunition and torpedoes.
6. The CSSQT Services do not provide specific technology to Japan.
The test scenarios developed are based on the capabilities included in
the ACS suite.
7. Japan currently operates eight Aegis destroyers with BMD
capability. Japan signed a General Security of Military Information
Agreement (GSOMIA), and continues to make progress in safeguarding
information. Japan was the first foreign customer to purchase the AWS
and is the only foreign customer with Aegis BMD capability. Japan has
scrupulously complied with end use monitoring requirements and there is
no evidence of physical tampering or compromise of hardware since Japan
first purchased the AWS in the early 1990s. Japan currently operates,
maintains, and supports the BMD capability in four Kongo class
destroyers, two Atago class destroyers, and two Maya class destroyers,
demonstrating a high level of readiness and proficiency. Japan has
completed CSSQTs on all previous Aegis equipped ships.
8. The highest level of classification of defense articles,
components, and services included in this potential sale is SECRET.
9. 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 system
effectiveness or be used in the development of a system with similar or
advanced capabilities.
10. A determination has been made that Japan can provide
substantially the same degree of protection for the sensitive
technology being released by the U.S. Government. The sale is necessary
in the furtherance of the U.S. foreign policy and national security
objectives outlined in the Policy Justification.
11. All defense articles and services listed in this transmittal
have been authorized for release and export to the Government of Japan.
