Dec. 25 (Asia Today) — South Korea’s defense procurement agency is accelerating efforts to develop and certify defense-grade semiconductors, warning that reliance on foreign supply chains for critical chips could delay weapons deployment and weaken long-term competitiveness in arms exports.

Modern weapon systems increasingly depend on semiconductors for core functions including missile guidance and navigation, radar detection and tracking, encrypted military communications and autonomous operation in drones and unmanned platforms, defense officials and industry experts say.

Analysts say dependence on overseas sources for such components creates vulnerabilities that go beyond cost. If access is disrupted by export controls, manufacturing changes or supply discontinuation, military programs can face delays because defense-grade parts often require retesting and recertification even after minor design or packaging changes.

The Defense Acquisition Program Administration said it launched a task force in January 2024 to prepare for a Defense Semiconductor Center and has been building a roadmap for project planning and management along with a dedicated reliability evaluation and certification function, according to a notice posted on the government innovation portal.

In a December policy briefing, the agency said it began research and development projects tied to defense semiconductors, including high-power radio-frequency components for radars and semiconductors for space communications.

Defense semiconductor applications span a growing set of systems, including transmit-receive modules for active electronically scanned array radars, processing chips for synthetic aperture radar on unmanned aerial vehicles, satellite communications components for small satellites and tactical-grade inertial sensors, analysts said.

DAPA has pursued center establishment in parallel with research programs aimed at building a domestic ecosystem. The agency said it selected five core technology projects in May, with four expected to begin within the year. In December, it announced the start of projects including space semiconductors for small satellite communications, tactical-grade gyro sensors, chips for unmanned aerial vehicle synthetic aperture radar and chips for active electronically scanned array radars, emphasizing a goal of reducing reliance on foreign technology.

The agency also held a defense semiconductor development forum in November that brought together government officials, industry and researchers, according to the report.

Experts said the next hurdles are less about initial research and more about building an ecosystem that can certify reliability and support sustained production.

Defense-grade semiconductors must perform under extreme conditions including temperature swings, vibration, shock, electromagnetic exposure and long storage periods, requiring testing infrastructure and standards that differ from civilian certification methods.

Analysts also said South Korea will need an end-to-end supply chain covering design, manufacturing, packaging and verification. Because defense chips are often produced in small volumes across multiple specialized variants, they can be deprioritized on commercial foundry and packaging lines unless trusted production capacity is secured.

Specialized investment will also be needed in areas such as compound semiconductors and radiation-hardened components used in radars, electronic warfare systems and satellites, the report said.

To ensure research translates into deployment, experts said development should be structured around early joint design involving military users, system integrators and component makers.

Analysts said defense semiconductors should be treated as national security infrastructure that affects the speed of force deployment, operational sustainability and export reliability, rather than as an optional industrial policy goal.
