US approves sale of SM-3 Block IIA ABM Interceptors to Japan

The U.S. State Department approved a possible Foreign Military Sale to Japan of up to 73 Standard Missile-3 (SM-3) Block IIA missiles for an estimated cost of $3.295 billion.

The Government of Japan has requested to buy up to seventy-three (73) Standard Missile-3 (SM-3) Block IIA missiles.  Also included are MK 29 Canisters with packing, handling, storage, and transportation (PHS&T) kits; up to ten (10) Special Assignment Airlift Mission (SAAM) flights; U.S. Government and contractor representatives’ technical assistance, engineering and logistical support services, and other related elements of logistics and program support.  The estimated cost is $3.295 billion.

These missiles are likely intended to be fitted on the Japan Maritime Self-Defense Force (JMSDF) Aegis destroyers such as the four Kongo-class, the two Atago-class or the future two Maya-class of destroyers.

These missile could also be deployed from the Aegis Ashore system recently procured by Japan. The U.S. Department of State approved the sale of two such batteries to Japan in January. They will be installed in Akita and Yamaguchi prefectures and are set to be operational from 2025.

US Approves Possible $1.15Bln Sale of 56 SM-3 Block IB Interceptors for Japan
September 12, 2018: A Standard Missile -3 Block IB Threat Upgrade (SM-3 Blk IB TU) missile launches from the Japan destroyer, JS ATAGO (DDG-177) during Japan Flight Test Mission-05 (JFTM-05). The Japan Maritime Self-Defense Force (JMSDF) and the United States Missile Defense Agency (MDA) announced the successful completion of the Aegis Ballistic Missile Defense (BMD) intercept flight test, in cooperation with the U.S. Navy, off the coast of Kauai in Hawaii. The event, designated Japan Flight Test Mission-05 (JFTM-05), was conducted in order to demonstrate a successful engagement of a target missile from the JS ATAGO using the sea-based midcourse engagement capability provided by Aegis BMD.

According to its developper and manufacturer Raytheon, The SM-3 interceptor is a defensive weapon the U.S. Navy uses to destroy short- to intermediate-range ballistic missiles. The interceptor uses sheer force, rather than an explosive warhead, to destroy its target. Its “kill vehicle” hits threats with the force of a 10-ton truck traveling 600 mph. This technique, referred to as “hit-to-kill,” has been likened to intercepting a bullet with another bullet.

Back in April this year, the U.S. State Department approved a similar FMS deal to Japan of up to fifty-six (56) Standard Missile-3 (SM-3) Block IB missiles for an estimated cost of $1.150 billion.

About SM-3 Block IIA Interceptor

The SM-3 Block IIA is designed to destroy SRBM (short range ballistic missile) and IRBM (intermediate-range ballistic missiles). It is a joint development project started in 2006 by Raytheon and Japan’s Mitsubishi Heavy Industries.

Compared to previous variant of the missile (like the SM-3 Block IB), the Block II1 variant features a larger rocket motor and a larger kinetic interceptor.

The SM-3 Block IIA successfully completed a full engagement test against a medium-range ballistic missile target in October 2018.
