South Korea weighs expanding Cheonghae Unit toward Strait of Hormuz
South Korea is weighing whether to expand the operating territory of its Cheonghae anti-piracy naval unit from the Gulf of Aden toward the Strait of Hormuz, defense officials said.
The review comes as Seoul prepares to seek parliamentary approval to extend the deployment before the current mandate expires on December 31. Defense Minister Kang Shin-chul told lawmakers that the ministry is reviewing various options regarding the unit’s mission scope and extension.
Departing from Busan Naval Base on October 4, the 49th Cheonghae Unit currently operates aboard the 4,400-ton destroyer ROKS Chungmugong Yi Sun-sin. The deployment typically includes a helicopter, up to three rigid-hull inflatable boats, and a maximum of 320 personnel, with a primary mission of escorting commercial vessels and protecting shipping lanes off Somalia since 2009.

South Korea Considers Strengthening Cheonghae Unit Role
The operational review follows a request from Washington for military contributions from allies to help secure the Strait of Hormuz amid the ongoing conflict with Iran.
President Lee Jae Myung stated during a news conference last month that South Korea would not send troops or military assets to participate in the war. However, he confirmed that the government was considering strengthening the Cheonghae Unit’s role in protecting Korean vessels, oil shipments, and citizens in the region.

The defense ministry has maintained that any potential expansion would support the unit’s existing anti-piracy and shipping protection duties. Officials argue the move would not constitute a direct response to the United States deployment request.
Seoul Weighs Legal Options for Operating Area Expansion
The current parliamentary authorization explicitly identifies the Gulf of Aden as the unit’s operating area. The mandate also contains a provision allowing missions in other designated waters when necessary to protect South Korean nationals.

In 2020, Seoul utilized that exact provision to expand the unit’s operations toward the Strait of Hormuz without seeking fresh parliamentary approval. It remains unclear whether the government will rely on that same legal provision this time or seek explicit parliamentary authorization for a wider operating area.
In addition to extending the deployment and potentially broadening the geographic zone, the government is reviewing a proposal to add a P-8A Poseidon maritime patrol aircraft to the unit to enhance surveillance coverage. No final decisions have been reached regarding either the aircraft addition or the expanded mission boundaries.
