South Korea's Defence Ministry on Monday, 4 August 2025, formally launched a new counterintelligence agency to combat espionage and terror threats from North Korea and other adversaries, as part of a sweeping institutional overhaul that dissolves the Defence Counterintelligence Command (DCC) — 49 years after its founding. The move marks the most significant restructuring of South Korea's military intelligence apparatus in decades.

What the New Agency Will Do

The newly established counterintelligence unit is mandated to 'proactively tackle future security threats,' according to a ministry release. It will work in coordination with domestic and foreign partner agencies to counter increasingly covert intelligence operations and terrorist activities linked to North Korea and other state actors.

Among its priority areas is preventing the leak of military secrets within the defence industry. The agency will also provide security support for strategic programmes — including maintenance, repair and overhaul (MRO) operations being conducted in cooperation with the US Navy. Protecting advanced technologies such as artificial intelligence (AI) and satellite systems from cyberthreats has also been flagged as a core responsibility.

Two Additional Bodies Launched Simultaneously

The counterintelligence unit is one of three new bodies being stood up under the reform plan. A separate security support unit was also inaugurated within the ministry on the same day, tasked with overseeing internal military security — including security audits for corps-level units or larger formations and investigations into security breaches.

A third body, a dedicated investigative unit to handle crimes threatening national security — such as espionage, treason, and cybersecurity offences — is also planned under the reform blueprint. The ministry had announced the overall restructuring plan in early June 2025, formally signalling the DCC's dissolution.

The Launch Ceremony

A formal inauguration was held at the former DCC headquarters in Gwacheon, just south of Seoul, and was attended by Defence Minister Ahn Gyu-back along with senior military officials. The venue itself carried symbolic weight — the same building that once housed the command now being replaced.

Why the DCC Was Dismantled

The DCC had long attracted criticism for wielding disproportionate influence through its broad intelligence-gathering mandate, and had faced repeated reform efforts under successive administrations. Its most recent — and most damaging — controversy came from its reported involvement in former President Yoon Suk Yeol's failed martial law imposition on 3 December 2024, which reignited public and political pressure for a fundamental overhaul. Critics argued the command had evolved into an instrument capable of being turned inward against domestic political actors rather than external threats.

What Comes Next

With the DCC's core functions now dispersed across new and existing agencies, South Korea's defence establishment will be watching closely to see whether the restructured architecture delivers sharper operational focus without the political entanglements that plagued its predecessor. The reform is being closely observed by regional security analysts given the persistent threat environment on the Korean Peninsula.
