In Daegu, South Korea, bolts for the U.S. Army's CROWS (Common Remotely Operated Weapon Station) were manufactured at $1.27 each. Under normal supply routes, these parts would not be delivered until February 2027. While it may seem like a small bolt, this indicates that the U.S. military's Indo-Pacific strategy is shifting from the phase of "forward stationing troops" to "repairing and maintaining combat power forward."
Transforming South Korea into a Manufacturing Hub for Supplies
The U.S. Army's 8th Army logistics support unit is attempting to establish a regional maintenance hub in South Korea by combining machining and metal 3D printing. According to Defense News, there are plans to introduce approximately $3 million worth of advanced manufacturing machinery by the summer of 2027, with an additional request of about $10 million for the fiscal year 2028. An example is provided where parts worth $36,000 requested by troops in Guam were produced for $82.
- Hub: The supply network of the 8th Army centered in Daegu, South Korea
- Method: Machining and metal additive manufacturing
- Deployment Locations: Army units in South Korea, Marine Corps in Okinawa, rotational forces in Hawaii
Importantly, the Army's supply hub accepts parts across service branches. The concept of manufacturing parts in South Korea for the Marine Corps in Okinawa to maintain combat power on the western side of the First Island Chain is not merely about cost reduction.
Implications for Japan
In the joint U.S.-Japan exercise "Keen Sword," which is focused on the Senkaku Islands and the Taiwan front, NMESIS and MADIS are expected to be deployed on Yonaguni Island, while HIMARS will be stationed on Ishigaki Island. Defense News reported that the Japan Ground Self-Defense Force's Type 25 anti-ship guided missile, with a range of about 1,000 kilometers, will also participate. Furthermore, according to Military Times, the U.S. Army is organizing a new multi-domain task force to integrate long-range firepower in the Indo-Pacific, planning to expand to approximately 2,100 personnel. The ability of dispersed missile units to quickly replenish not only munitions but also vehicles, sensors, and launcher components will determine their survivability.
In my view, what determines the deterrent capability of the First Island Chain is not just the range of missiles, but how quickly we can return malfunctioning equipment to the front lines.
Gaps Between Capability and Intent
The manufacturing hub in South Korea can practically reinforce U.S.-Japan-South Korea security cooperation. However, there are still obstacles regarding manufacturers' intellectual property rights, sharing of design data, and integration with existing Army supply systems. Simply placing a 3D printer does not mean military parts can be produced immediately; compliance testing and accountability are necessary.
Moreover, if the South Korean hub remains exclusive to the U.S. military, interoperability with Japan's Self-Defense Forces will be limited. To view the Japan Maritime Self-Defense Force's escort ships, the Japan Ground Self-Defense Force's missile units, and the U.S. Marine Corps in Okinawa on the same supply map, standardization of part numbers, maintenance data, and transportation priorities is essential. The real challenge lies not in the lack of manufacturing capacity, but in determining "who, with what standards, and which parts to prioritize" among allies during peacetime.
Reference Information
The U.S. Army is manufacturing components for the Common Remotely Operated Weapon Station (CROWS) in Daegu, South Korea, at a cost of $1.27 each. This initiative is part of a broader strategy to establish a supply chain that supports military operations in the Indo-Pacific region, with plans to invest $30 million in advanced manufacturing by 2028. The supply chain will enhance interoperability among U.S., Japanese, and South Korean forces.
