On 21 January the South Korean Ministry of National Defence (MND) announced that it would temporarily expand and the operational remit of its Cheonghae anti-piracy unit from the Gulf of Aden to include the Strait Of Hormuz. The move comes amid ongoing efforts by the US to secure naval support from its allies in protecting oil tankers transiting the strait, following the significant escalation in US-Iran tensions in early January. However, the Cheonghae unit will not be joining the US-led International Maritime Security Construct (IMSC) and will instead cooperate with the IMSC while remaining nominally independent.
NYA Analysis:
Despite its historical role as a prominent US ally, South Korea had, prior to this stage, refrained from direct engagement in the Strait of Hormuz due to domestic hostility towards further military contributions to US operations. The Cheonghae anti-piracy unit, initially deployed to the Gulf of Aden in 2009, will expand its patrol range by 251% from 1,130km to 3,966km by including the Persian Gulf in its operations. The remit’s expansion serves as a means for the MND to contribute to maritime security efforts within the Strait of Hormuz without requiring pproval from the South Korean parliament, which it would be unlikely to secure due to domestic hostility to further military deployments. However, despite domestic criticism of Cheonghae’s operational expansion the unit is likely to remain in place over the medium term, as over 70% of South Korea’s oil imports transit through the Strait. Consequently, the redeployment of the Cheonghae unit is likely to represent the sole involvement of South Korean naval forces in the Strait of Hormuz in the medium term.
