US Typhon Deployment in Japan Expands Allied Missile Reach and Draws Regional Warnings

A new missile presence at Iwakuni

The United States has brought its Typhon missile system to Japan for the first time, unveiling a mobile battery at Marine Corps Air Station Iwakuni in southwestern Japan during Resolute Dragon 25. The exercise involves more than 19,000 US and Japanese personnel and focuses on maritime defense, logistics and operations along coastlines, including scenarios for retaking remote islands.

The battery will not fire live missiles during the drill. Japanese and US officials say its presence is tied to the exercise and that it will leave afterward. Even without a launch, the deployment gives the alliance another way to demonstrate that it can move weapons capable of striking land and sea targets into the region as tensions rise with China in the East China Sea and across the Taiwan Strait.

Typhon combines Tomahawk cruise missiles, commonly described as having a range of roughly 1,000 miles, or about 1,600 kilometers, with the shorter reaching Standard Missile 6, known as SM-6. From suitable positions in southwest Japan, that combination can threaten coastal bases, shipping and other targets across important parts of the western Pacific.

Japan is also changing its own military posture. Its 2022 National Security Strategy committed the country to acquiring a counterstrike capability and raising defense spending to around 2 percent of gross domestic product by 2027. Counterstrike means having the ability to hit targets supporting an attack, alongside defenses intended to intercept incoming missiles. Longer reaching Japanese weapons, closer training with the United States and stronger ties with the Philippines are part of that shift.

How Typhon reached Japan

The Iwakuni deployment follows appearances in the Philippines and Australia, showing how the United States is moving the system among allied countries. A launcher arrived in the Philippines in April 2024 for a major exercise and remained there at Manila's request. In July 2025, Typhon deployed to Australia and fired an SM-6 at a maritime target during Talisman Sabre.

Japan's exercise deployment extends that pattern along the First Island Chain, the string of territories running from Japan through Taiwan to the Philippines. Allied forces aim to use islands and coastal positions to threaten ships and land targets, complicating Chinese military planning while showing partners that Washington and Tokyo can respond quickly to a crisis.

• 2019: The Intermediate Range Nuclear Forces Treaty ended, opening the way for US ground launched missiles with ranges previously prohibited by the agreement.
• 2022: Japan's National Security Strategy committed to counterstrike capability and defense spending of around 2 percent of GDP by 2027.
• April 2024: Typhon arrived in the Philippines for an exercise and subsequently stayed at Manila's request.
• July 2025: Typhon deployed to Australia and fired an SM-6 at a maritime target during Talisman Sabre.
• Resolute Dragon 25: The United States brought Typhon to Japan for the first time, with no live firing planned.

The Philippines experience gives the Japanese deployment particular political weight. A system brought in for training can become a longer presence if the host government agrees. Tokyo and Washington describe the Iwakuni visit as temporary, with departure following the exercise; no exact departure date was given.

What the battery can fire

A typical Typhon battery includes an operations center, four launchers, prime movers and trailers. Its launch equipment uses proven vertical launch technology adapted for mobile operations on land. Each launcher can carry four missiles, giving a battery up to 16 missiles ready to fire before reloading.

Tomahawk supplies the longer reaching precision strike option. It can attack fixed targets of high military value, including headquarters and critical infrastructure. SM-6 has a shorter reach, often described in the hundreds of kilometers, and several possible roles: air defense, ballistic missile defense at short ranges, and, in special modes, attacks on ships and certain land targets.

The two missile types give commanders different choices. Tomahawk can reach distant fixed locations, while SM-6 adds options against maritime targets and for defense at shorter distances. Mobile targets, including ships and launchers, require a wider network of sensors to find them, track their movement and supply usable targeting information.

Col. Wade Germann, commander of the US Army's 3rd Multi Domain Task Force, described the purpose of that combination before Typhon's unveiling in Japan:

Employing multiple systems and different types of munitions, Typhon is able to create dilemmas for the enemy.

Typhon can receive targeting data from aircraft, ships, satellites and sensors on the ground. Its crews are meant to set up quickly, fire and relocate. A battery could operate from a coastline or an inland road, then move before an opponent locates and attacks its firing position. Launchers can be dispersed, and reloads can be staged farther away from exposed positions.

Connecting missiles, sensors and allied forces

Resolute Dragon 25 spans much of Japan and tests how American and Japanese forces operate together. Maritime defense and littoral operations, meaning activity around shores and nearby waters, are central to the exercise. Practicing logistics matters alongside firing capability because dispersed units need transport, supplies, communications and replacement missiles.

The US Army's Multi Domain Task Force brings long range weapons together with intelligence, cyber operations, electronic warfare and space capabilities. Its role is to connect information gathering with decisions and attacks. The military calls that process a kill chain: finding a target, tracking it, deciding how to engage it and delivering the strike.

Typhon fits into that wider network rather than operating alone. US and Japanese forces are working to share targeting information rapidly, including with Japanese units equipped with upgraded Type 12 missiles for attacks on ships and land targets. The exercises aim to improve interoperability, meaning the ability of different forces and equipment to work together, shorten decision times and demonstrate movement and strike capability across Japan's archipelago.

The US Marine Corps is fielding a separate system for attacking ships from land, NMESIS, in the Ryukyu Islands. Alongside Japanese missile units and Typhon, these systems can create overlapping areas of threat against ships and coastal bases in the East China Sea. Dispersing launchers and sensors across islands is intended to make allied forces harder to suppress and restrict an adversary's movement through key straits and sea lanes.

What changes on the regional map

Tomahawk missiles launched from positions in southwest Japan can reach a wide range of coastal bases, ports and logistics hubs along China's eastern seaboard. Their reach also extends deep into the East China Sea, the Bashi Channel and important approaches to Taiwan. From western Japan, the system can put the entire Korean Peninsula within range.

SM-6 complements that reach with maritime strike and more advanced air defense options at shorter distances. Those roles could help protect choke points, the narrow passages through which ships must travel, and threaten vessels approaching Japanese waters. The two missiles therefore affect both the bases supporting military operations and some of the ships conducting them.

Mobility adds another problem for China's People's Liberation Army. Typhon's four launchers can disperse and use terrain or civilian traffic to conceal their movements. After firing a salvo, crews can relocate. Finding and suppressing such a battery requires surveillance, missiles and airpower that China must also allocate to other missions.

China still has the region's largest missile force, including ballistic missiles designed to attack ships, long range cruise missiles and hypersonic glide vehicles such as the DF-17. Its arsenal also includes weapons launched from the sea, such as the YJ-21. Beijing's approach, known as anti access and area denial, aims to keep US and allied forces at a distance and restrict their operations within contested areas.

Typhon gives the alliance another means of challenging that approach by threatening targets supporting long range attacks against Japan and increasing the costs of conflict. Its usefulness depends on the sensor network, cyber capabilities and other allied forces that help it locate targets, communicate and survive.

China and Russia warn against the deployment

China's government criticized Typhon's appearance in Japan as a threat to security in Northeast Asia. Beijing has also objected to deployments in the Philippines and Australia. Chinese officials describe the combined effect as a growing ring of missile systems aimed at the mainland and its coastal bases.

Chinese Foreign Ministry spokesperson Lin Jian called for the system's withdrawal from Asian countries hosting it. At a regular press conference, he described Beijing's objections:

The deployment of the Typhon medium range missile system in Asian countries undermines the legitimate security interests of others, fuels the risk of regional arms race and military confrontation, and poses a substantial threat to regional strategic security.

Russia has raised similar concerns, concentrating on the ability of US weapons to reach its Far East. Russian Foreign Ministry spokesperson Maria Zakharova warned that further expansion of the deployments near Russia would draw a response:

If tensions continue to escalate, Russia will be forced to take necessary military technical countermeasures to safeguard its security and interests.

North Korea has repeatedly opposed the growth of allied strike capabilities. With the Korean Peninsula within reach of missiles launched from southwest Japan, Pyongyang is likely to use Typhon as further justification for missile tests and closer cooperation with China and Russia. Japanese officials point to North Korean launches near Japan as a reason to build counterstrike options and integrated missile defenses.

Tokyo's wider policy also reflects concern about coercion from China and the need to monitor Russian forces operating in the Far East. The same weapons that Japan and the United States present as deterrents are being described by neighboring governments as threats, adding diplomatic pressure to the military competition.

Japan's spending shift and local concerns

Japan resisted hosting US strike systems based on land for years. Its 2022 National Security Strategy placed greater weight on counterstrike capability, weapons with longer reach and integrated air and missile defense, which connects detection and interception systems so they can respond together.

Tokyo is increasing defense spending and accelerating purchases of F-35 fighters, refueling aircraft, maritime patrol planes and precision munitions with long ranges. The goal of reaching around 2 percent of GDP by 2027 aligns Japan more closely with NATO spending standards. Domestic missile upgrades and more frequent joint training support the same policy change.

Japan is upgrading the Type 12 missile to extend its range to roughly 1,000 kilometers and improve its ability to survive jamming and interception. Used with mobile launchers and connected to an air and missile defense network, it would strengthen Japan's ability to threaten targets along China's coastline and operate alongside Typhon and NMESIS.

Communities in Okinawa and across the southwest islands remain concerned about becoming targets if missiles are stationed nearby. Public opinion is cautious, and Japanese leaders have treated visiting US systems as an opportunity to test military operations and gauge political reactions without committing to permanent bases. The temporary deployment at Iwakuni brings that domestic debate into the same discussion as regional deterrence.

The Philippines, sea lanes and coast guards

The Philippines has deepened military cooperation with the United States and is acquiring missiles with longer ranges of its own. Japan and the Philippines recently ratified a reciprocal access agreement that makes visits, joint training and deployments easier for their forces. Stronger missile forces along this regional arc are intended to improve deterrence and help protect sea lanes carrying Japanese trade through the South China Sea into the western Pacific.

Japan's economic lifelines depend on those waters. Conflict or a campaign of coercion that interrupts shipping would affect energy imports and trade flows. Tokyo, Manila and Washington are therefore expanding maritime law enforcement as well as military capabilities.

The US Coast Guard is expanding its Sentinel class cutter fleet in the western Pacific, adding capacity in Guam. Japan is launching new large coast guard vessels with helicopter flight decks. These assets handle routine encounters involving fishing fleets and coast guards, providing capacity between peacetime patrols and wartime missions.

Japan's experience with regular Chinese incursions near the Senkaku Islands has shaped these priorities. Better sensors, data sharing and legal arrangements for joint activity can make it harder for gray zone tactics to succeed. Such tactics include dangerous maneuvers by coast guard ships, using pressure that falls below open warfare. The Japan Philippines agreement connects this cooperation with the ability of forces to train and deploy together.

The missile competition after the INF Treaty

The Intermediate Range Nuclear Forces Treaty barred the United States and Russia from fielding missiles launched from land with ranges between 500 and 5,500 kilometers. Its collapse in 2019 removed a major arms control limit dating from the Cold War and opened the way for the US Army to develop Typhon. Asia never had a similar regional ban.

China built a vast arsenal capable of threatening bases and ships across the western Pacific. The United States responded with systems including Typhon and NMESIS and plans to station long range weapons in Europe beginning in 2026. Strategic rivalry has also pushed countries across the Indo Pacific to accelerate their own missile programs.

Japan is extending the reach of its Type 12, while South Korea's Hyunmoo series is growing in range and precision. Australia is investing in domestic missile production and missiles with long ranges for use against aircraft and surface targets. India has begun exporting BrahMos missiles to the Philippines.

More accurate and faster missiles leave commanders less time to make decisions during a crisis. Mobile weapons that are difficult to locate can increase the temptation to attack first. Military hotlines, crisis communications, clear exercise rules and transparent notifications can reduce the risk of mistaken decisions. Without those safeguards, repeated deployments and responses could make a crisis in Northeast Asia sharper and harder to manage.

What comes after Resolute Dragon

Tokyo and Washington describe Typhon's presence at Iwakuni as an exercise deployment rather than a permanent basing decision. Future visits would show whether batteries return more frequently, remain longer or operate from additional locations in Japan's southwest islands.

The US Army's Multi Domain Task Force is likely to play a larger role in future exercises as it becomes more closely connected with US Forces Japan. That command is shifting toward a joint warfighting posture, bringing different military services into a more unified operational structure. Germany is preparing to host long range weapons and a Multi Domain Task Force from 2026, reflecting US efforts to standardize these capabilities across different regions.

Japan's integrated air and missile defense network is expanding, the Marines will field more NMESIS units, and the Philippines is building coastal missile regiments. Interest in Typhon has emerged in Europe and Asia, with Germany and the Philippines watching its performance closely.

China could respond through missile tests, exercises near Japan, additional deployments and diplomatic pressure on Tokyo and Manila. Russia and North Korea are expected to continue describing the allied moves as destabilizing. For the governments involved, crisis management, transparency and clear signaling will matter alongside the weapons themselves as they seek deterrence without an escalating cycle of confrontation.
