South Korea to expand anti-piracy unit operations closer to Strait of Hormuz

The Cheonghae unit is South Korea’s anti-piracy naval force for protecting commercial vessels. It has operated in the Gulf of Aden since 2009. The planned change matters because the unit would work closer to the Strait of Hormuz, a major route for South Korea’s oil imports.

The unit currently has a 4,400-ton-class destroyer, a maritime operations helicopter, up to three rigid-hull inflatable boats, and around 300 service members. The proposed mission area would include waters near Duqm in Oman, about 650 kilometers from the strait. South Korea also plans to send a P-8A maritime patrol aircraft.

The deployment extension needs approval from parliament, President Lee Jae Myung, and the cabinet. The current authorization is set to expire at the end of 2026. The mission would remain focused on safeguarding navigation, while Seoul has said it does not want to become drawn into conflict.

The Strait of Hormuz is a narrow maritime passage between the Persian Gulf and the Gulf of Oman. It connects oil-producing areas around the Gulf with the wider ocean shipping network. Because ships carrying energy supplies must pass through this confined route, disruption there can quickly affect deliveries.

For South Korea, the strait is especially important. The Industry Ministry said South Korea sourced 70% of its oil supplies from the Middle East in 2025. Most of that oil was delivered through the Strait of Hormuz. A safe passage allows tankers and other commercial vessels to continue moving between suppliers and South Korean ports.

The article does not provide the strait’s width or exact global traffic share. It does show why Seoul is considering a larger maritime security role nearby. Protecting navigation could help keep vital shipping moving without deploying forces directly into the war.

The planned reinforcement combines more people with stronger surveillance. South Korea will deploy a P-8A maritime patrol aircraft and increase the Cheonghae unit’s personnel by 75. These additions are intended to support navigation security near the Strait of Hormuz.

The existing unit already includes a 4,400-ton-class destroyer, a maritime operations helicopter, up to three rigid-hull inflatable boats, and around 300 service members. The destroyer provides the main naval presence. The helicopter and smaller boats can support maritime operations around commercial vessels. The P-8A would add long-range patrol and monitoring capability, according to the article’s reported plan.

The exact final force size depends on political approval. Seoul must submit a motion to parliament, and the proposal also requires approval from President Lee Jae Myung and the cabinet. If approved, the unit would operate near Duqm in Oman, about 650 kilometers from the strait.

South Korea has a strong interest because its economy depends heavily on imported oil. The Industry Ministry reported that 70% of the country’s oil supplies came from the Middle East in 2025. Much of that energy moved through the Strait of Hormuz, making the route important to South Korea’s regular supply chain.

The Cheonghae unit was created for a related purpose: ensuring safe navigation for commercial vessels. Its current base of operations is the Gulf of Aden, where it has been stationed since 2009. Expanding toward Duqm would place South Korean maritime assets closer to the route used by oil shipments and other commercial traffic.

Political pressure also matters. US President Donald Trump criticized Seoul for insufficient support for the war in Iran. South Korea’s government is considering a larger role in protecting navigation, but President Lee Jae Myung said Seoul would not deploy military assets in a way that could pull it into conflict. The proposed mission reflects both needs.

South Korea sourced 70% of its oil supplies from the Middle East in 2025, according to the Industry Ministry. That is the specific share given in the article. It shows how strongly South Korea’s energy supply depends on production and shipping routes connected to the region.

The article adds that most of this Middle Eastern oil was delivered through the Strait of Hormuz. However, it does not state the exact percentage or volume that traveled through the strait. Therefore, the precise amount carried through the waterway cannot be calculated from the information provided.

This dependence helps explain Seoul’s proposed expansion of the Cheonghae unit. The force would patrol closer to Duqm in Oman and support safe navigation for commercial vessels. South Korea plans to add a P-8A aircraft and 75 personnel, subject to parliamentary, presidential, and cabinet approval.

A disruption near the Strait of Hormuz could threaten South Korea’s energy supply because the country relies heavily on imported oil. The article states that 70% of its oil came from the Middle East in 2025, and most of those supplies traveled through the strait. It does not provide a forecast for economic losses.

If tankers could not pass safely, deliveries might be delayed or interrupted. South Korean buyers could then face higher costs for available oil. Those costs could spread through transportation, electricity, manufacturing, and other businesses that use fuel. These are established economic effects of disrupted energy shipping, not figures stated in the article.

The proposed patrol expansion is meant to support safe navigation rather than join the war. South Korea plans to add a P-8A aircraft and 75 personnel. Seoul must still secure approval, while President Lee Jae Myung has warned against deploying assets in a way that could draw the country into conflict.

Countries use naval patrols to protect commercial vessels, deter piracy or attacks, and support freedom of navigation. Maritime law provides rules for ships using international waters and for states responding to threats. Safe shipping matters because disruptions can endanger crews, delay cargo, and interrupt energy supplies. The article specifically describes the Cheonghae unit’s mission as ensuring safe navigation.

The unit illustrates how this works. It operates a destroyer, helicopter, boats, and service members in the Gulf of Aden. The proposed expansion would move operations toward Duqm, Oman, closer to the Strait of Hormuz. A P-8A aircraft and 75 additional personnel would strengthen monitoring and response capacity.

South Korea’s limits are political as well as military. The deployment needs parliamentary, presidential, and cabinet approval. President Lee Jae Myung said Seoul would not send assets in a way that could draw the country into conflict. The mission must therefore protect shipping without becoming combat support for the war.
