In a significant move to bolster regional security in the Indo-Pacific, the US State Department has recently approved a $39 million foreign military sale to Japan for up to 16 AGM-158B/B-2 Joint Air-to-Surface Standoff Missiles with Extended Range (JASSM-ER) and associated equipment.
This sale underscores the growing defense cooperation between the two nations and Japan’s commitment to enhancing its military capabilities to address emerging threats from North Korea and China.
A Closer Look at the JASSM-ER
Manufactured by Lockheed Martin, the AGM-158B/B-2 JASSM-ER is a highly advanced cruise missile designed for long-range precision strikes.
Utilizing GPS guidance and an internal navigation system, the missile follows a preprogrammed path to its target.
Equipped with a 1,000lb warhead and an imaging infrared seeker, the JASSM-ER is capable of striking targets with remarkable accuracy from up to 900 kilometers (559 miles) away.
Its flexibility allows it to be launched from various aircraft, including Japan’s F-15J and F-35 fleets.
This sale also includes crucial non-major defense equipment such as dummy air training missiles, anti-jam GPS receivers, spare parts, integration and testing support, and logistics services.
These additions will ensure the seamless integration of the JASSM-ER into the Japan Air Self-Defense Force (JASDF) while supporting training and operational readiness.

Strengthening US-Japan Defense Cooperation
The approval of this sale aligns with US foreign policy objectives to support allies in the Indo-Pacific.
The Defense Security Cooperation Agency noted that this deal will enhance Japan’s ability to counter current and future threats while contributing to regional political stability and economic progress.
With Japan’s focus on modernizing its defense capabilities, the JASSM-ER will play a pivotal role in extending the country’s stand-off strike capabilities and improving its deterrence posture.
This is not Japan’s first acquisition of JASSM-ER missiles.
In August 2023, Japan procured 50 of these missiles through a $104 million Foreign Military Sale to outfit its upgraded F-15 fighter jets.
Together, these acquisitions highlight the country’s commitment to maintaining a robust and modernized military force capable of addressing evolving regional challenges.
Broader Implications for Regional Security
Japan’s acquisition of the JASSM-ER comes amid heightened tensions in the Indo-Pacific region, driven by North Korea’s missile tests and China’s growing military presence.
By equipping its air fleet with long-range precision strike capabilities, Japan is better positioned to respond to potential aggression and safeguard its territorial integrity.
This move also strengthens interoperability between the US and Japan, reinforcing the strategic partnership that underpins regional security.
The ability to share advanced defense technology fosters collaboration and enhances the collective capabilities of allied forces.
Lockheed Martin’s Role in Defense Modernization
As the principal contractor, Lockheed Martin continues to play a critical role in producing and delivering the JASSM-ER missiles.
The company has expanded its production capabilities with a 225,000-square-foot facility that incorporates robotic paint lines, enhanced automation, and dynamic factory modeling.
This facility ensures faster, more cost-effective production of JASSM-ER systems, which are not only critical for US allies but also vital for American defense initiatives.
Lockheed Martin’s ongoing efforts to increase production capacity highlight the importance of these systems in supporting global defense objectives.
Additionally, the company’s focus on innovation ensures that nations like Japan receive the most advanced and reliable systems to enhance their security and defense operations.
Japan’s Defense Modernization Agenda
Japan’s defense budget for 2024 stands at $72.3 billion, with a projected compound annual growth rate of over 4 percent from 2025 to 2029. This reflects the nation’s determination to counter rising threats and invest in modernizing its military.
In addition to acquiring long-range missile systems, Japan is also focusing on the development of stealth fighter jets and compact warships, further enhancing its defense capabilities.
This comprehensive modernization effort demonstrates Japan’s commitment to maintaining a strong defense posture and its readiness to address the challenges posed by regional adversaries.
By integrating advanced systems like the JASSM-ER, Japan is not only safeguarding its national security but also contributing to the stability of the Indo-Pacific region.
Final Thoughts
The approval of the $39 million JASSM-ER sale to Japan marks a significant step in strengthening the US-Japan alliance and enhancing regional security.
With advanced long-range strike capabilities, these missiles will provide Japan with a powerful deterrent against potential threats while reinforcing its strategic partnership with the United States.
As Japan continues to modernize its military and invest in cutting-edge defense technology, the country is positioning itself as a key player in maintaining stability in the Indo-Pacific. This deal underscores the shared commitment of the US and Japan to counter emerging challenges and secure a safer future for the region.
