The JMSDF is working closely with the USA on missile defense activities. Air Force cooperation has also improved by leaps and bounds, allowing for much closer coordination with the USA in all aspects including missile tracking.

Japanese involvement includes modification and improvements to the SM-3 long-range anti-air/ABM missile. This weapon will form the outer layer of Japan’s ABM system, deployed from its current fleet of 4 Kongo Class AEGIS destroyers. The inner layer will consist of Japan Self Defense Forces PAC-3 Patriot missiles, and together they will form the initial ballistic missile defense for mainland Japan.

This article covers the elements of those request as they are fulfilled… and tested. The latest news following the JS Kongo’s successful BMD test is a partial contract that funds the modernization of one of its sister ships…

SM-2 (top), SM-3
 

There is no word on whether this purchase may serve to offset the recent cuts to the SM-3 program by the US, which could keep a key signal processor from coming on line and delay the program by up to a year.

Japan already has the upgraded AEGIS Weapon System and SM-3 Block IA Standard missiles in its inventory and will have no difficulty absorbing the additional upgraded Weapon System and missiles. The JMSDF has four AEGIS destroyers operating with SM-2 missiles at sea; the fifth and sixth AEGIS destroyers are under construction. The JMSDF is fully capable of integrating the modified AEGIS Weapon System and SM-3 Block IA into its operational forces and will receive data sufficient to maintain and support the systems. Presumably, this will include Cooperative Engagement Capability for its Kongo-Class AEGIS destroyers.

Japan’s agreement to provide fuel/logistics to U.S. and allied ships supporting Operation Enduring Freedom and its deployment of an AEGIS destroyer to the Indian Ocean have focused new obligations on Japan. This proposed sale is consistent with these U.S. objectives and with the 1960 Treaty of Mutual Cooperation and Security.

The principal contractors will be:

• Lockheed-Martin Maritime System and Sensors in Moorestown, NJ
• Raytheon Company Equipment Division in Andover, MA
• BAE Systems in Minneapolis, MN

There are no known offset agreements proposed in connection with these potential sales.

JS Kongo fires SM-3

Dec 28/07: Lockheed Martin Maritime Sensors and Systems of Moorestown, NJ receives a $40,.4 million firm-fixed-price and cost-plus-fixed-fee contract modification to fulfill a Japan AEGIS ship program requirement to procure BMD Block 2004 capability for a Kongo Class destroyer. A subsequent Reuters report established that this is the 3rd AEGIS upgrade contract, and adds that “A contract for the fourth ship, Kirishima, now looks set “to follow by year’s end, if not sooner,” said Ken Ross, a Lockheed spokesman in Moorestown, New Jersey.”

Work will be performed at Moorestown, NJ and is expected to be complete by November 2009. The contract funds will not expire at the end of the fiscal year. The Missile Defense Agency Command in Dahlgren, VA issued the contract, and Japanese Foreign Military Sales funds will be used. The modification will be incrementally funded and at award will obligate $359 million on award. (N00024-06-C-6106).

Dec 17/07: Success! The JS Kongo fires an SM-3 Block 1A missile, which tracks and kills its ballistic missile target. USS Lake Erie [CG 70] also participates as a secondary, using its radar to track the target. Read “Japanese Destroyer JS Kongo Intercepts Ballistic Missile” for more.

Nov 6/07: The JS Kongo participates in an ABM exercise with a fully functional AEGIS BMD system, using it to to detect, track and conduct a simulated engagement of the ballistic missile targets. In the first dual-firing test, 2 SM-3 Block IA missiles fired simultaneously from the USS Lake Erie [CG 70] destroy 2 short-range ballistic missile targets launched from the U.S. Navy’s Pacific Missile Range Facility on Kauai, Hawaii. The test marked the 10th and 11th successful intercepts for the Aegis Ballistic Missile Defense system’s SM-3. Kongo is scheduled to conduct Japan’s first firing flight test in late 2007. Lockheed Martin release.

July 25/07: Lockheed Martin Maritime Sensors and Systems of Moorestown, NJ received a $33.1 million firm-fixed-price contract modification to fulfill the Japan AEGIS ship program requirement to procure AEGIS BMD Block 2004 capability for the JS Chokai [DDG-176]. Work will be performed at Moorestown, NJ and is expected to be complete by February 2009. The Naval Sea Systems Command, Washington, D.C. is sued the contract (N00024-06-C-6106). See Aug 7/07 Lockheed Martin release.

DDG-176 Chokai

June 8/07: The US Defense Security Cooperation Agency announces Japan’s formal request [PDF format] request for Ballistic Missile Defense upgrades to one AEGIS Weapon System (Lockheed-Martin Maritime System and Sensors in Moorestown, NJ), AEGIS BMD Vertical Launch System ORDALTs (BAE’s Mk41 modifications, Minneapolis, MN), 9 SM-3 Block IA STANDARD missiles (Raytheon in Tucson, AZ) with MK 21 Mod 2 canisters, containers, spare and repair parts, publications, documentation, supply support, U.S. Government and contractor technical assistance and other related elements of logistics support. The systems will be installed on Japan’s Kongo Class AEGIS destroyers, and the total value, if all options are exercised, could be as high as $475 million. The Japanese destroyer JS Moyoko [DDG-175] may be the target of this request.

The July 25/07 entry strongly suggests that this is for the JDS Chokai [DDG-176], which is the last of the current Kongo Class destroyers; the 5th and 6th Improved Kongo Class ships currently under construction will reportedly have AEGIS BMD capability pre-installed.

June 5-6/06: The US DSCA announces a pair of requests from Japan for Standard-family naval air and missile defense systems, as well as destroyer BMD upgrades. The total value, if all options are exercised, could be as high as $528 million. Raytheon, Lockheed, and BAE are the primary contractors.

The first sale for $458 million sale involves 9 longer-range SM-3 missiles plus ballistic missile defense upgrades to one AEGIS Weapon System, AEGIS BMD Vertical Launch System (VLS) alternations, and other support. The JMSDF destroyer JS Chokai [DDG-176] may be the target of the request.

The second sale is for $70 million if all options are exercised, and involves up to 44 shorter-range SM-2 Block IIIB Standard Missiles that serve as the mainstays of the Kongo Class AEGIS destroyers’ air defense, plus various forms of support. See full DID coverage.

July 15/05: Lockheed Martin Maritime Sensors and Systems wins a $124 million cost-plus-award-fee contract modification to upgrade the Japanese AEGIS destroyer JS Kongo [DDG-173] to give it AEGIS Ballistic Missile Defense Block 2004 capability. Japan’s Kongo-Class destroyers are based on the USA’s Flight II DDG 51 Arleigh Burke Class, but feature many modifications both internally and externally.

Work on this contract will take place in Moorestown, NJ (78%); Baltimore, MD (15%); Eagan, MN (4%); and Aberdeen, SD (3%); and should be complete by November 2007. The project was not bid out, but was rather awarded by the Naval Sea Systems Command in Washington, DC under contracting activity N00024-03-C-6110. See also Lockheed release.

JS Kirishima

June 29/05: The US DSCA communicates [PDF] Japan’s official request for 9 SM-3 Block IA Standard missiles with MK 21 Mod 2 canisters, Ballistic Missile Defense (BMD) upgrades to one AEGIS Radar & weapon control system, AEGIS BMD Vertical Launch System ordnance alternations (ORDALTs), containers, spare and repair parts, publications, documentation, supply support, U.S. Government and contractor technical assistance and other related elements of logistics support. The total value, if all options are exercised, could be as high as $387 million.

Sources are unclear, but this could be a request targeted at the first-of-class JS Kongo [DDG-173]. Some reports peg the JS Kirishima [DDG-174] as Japan’s first ship to receive the upgrades – albeit only AEGIS Long Range Surveillance & Tracking version 3.0, which does not include engagement. Since this announcement refers to upgrades that include “AEGIS radar and weapon control,” and the May 5/04 announcement does not, the assumption is that this is targeted to the JS Kongo (aka. Kongou), and the May 2004 request was for the JS Kirishima.

May 5/04: The US DSCA announces [PDF] Japan’s request for 9 SM-3 Block 1A Standard missiles with MK 21 Mod 2 canisters, Ballistic Missile Defense (BMD) upgrades to one AEGIS Weapon System, AEGIS BMD Vertical Launch System ORDALTs and logistics support for an estimated value of $725 million.
