A projectile struck the tanker MKD Vyom near the strait of Hormuz, igniting an engine room fire. The vessel is the second commercial ship hit in the strait's approaches within 72 hours, following the MV Skylight, struck off Oman with four crew injured. The weapon has not been publicly attributed, but anti-ship missiles, rockets, and explosive-laden drones are all within the arsenal Iran deploys from its southern coast.
The IRGC had broadcast on VHF Channel 16 — the international maritime distress frequency — that "no ships may pass" through the strait. Mohsen Rezai simultaneously called the waterway "officially open" while designating US warships as "legitimate targets". The MKD Vyom's burning engine room resolves that contradiction. Commercial operators do not parse diplomatic ambiguity; they read casualty reports and war-risk advisories.
An engine room hit on a loaded tanker is among the most dangerous casualties a commercial vessel can sustain — no armour, minimal damage-control capability, and cargo measured in hundreds of thousands of barrels of flammable hydrocarbons. During the 1984–88 Tanker War, similar strikes frequently led to total vessel losses. The US Navy eventually escorted tankers through the strait under Operation Earnest Will in 1987. No comparable escort has been announced; the US Fifth Fleet's assets are committed to offensive strikes against Iranian military targets, not to protecting commercial shipping.
