HMM Namu Hormuz Attack 2026: Shipping Insurance and Maritime Law After the Strike

# HMM Namu Hormuz Attack 2026: Shipping Insurance and Maritime Law After the Strike

> **Quick answer:** Seoul confirmed May 11 that the HMM Namu was struck by two unidentified aerial objects on May 4, leaving a crater 5 meters wide and 7 meters deep in the hull. HMM holds approximately $65.3 million in war-risk coverage from five South Korean insurers led by Hyundai Marine & Fire Insurance — enough to cover the hull damage, but the policy explicitly excludes lost operating revenue during the estimated 1-2 month repair window. Because the attacker has not been identified, the state-to-state liability pathway under UNCLOS is effectively blocked, leaving the full financial burden on the insurance policy and the shipowner.

HMM Namu was anchored in the Strait of Hormuz on May 4, 2026 when two objects — captured on CCTV, still unidentified — struck the stern in rapid succession. The blast crater was 5 meters wide and 7 meters deep, large enough to qualify as precision-weapon damage rather than an accident. All 24 crew members survived. South Korea's government waited until May 11 to make the incident public — after briefing the Pentagon — and has since declined to name an attacker, saying "we are not making any assumptions at this stage." That careful phrasing is not diplomatic boilerplate. It is the direct result of how maritime insurance and international law interact when a weapon hits a civilian ship and the firer stays anonymous.

## What Happened on May 4: The Strike Mechanics Matter for Insurance

The two objects struck the HMM Namu approximately one minute apart, both hitting the stern. South Korean investigators recovered debris believed to be from the objects' engines — consistent with a drone or cruise missile rather than a mine or torpedo, both of which the forensic team explicitly ruled out based on the damage geometry.
