Two rockets strike Yanbu Pride, causing explosions and starting a fire in one of her holds that is quickly extinguished.^[7]
• May 18 – An Iraqi Air Force missile attack sinks the 17,000-ton Panamanian bulk carrier Fidelity in the Persian Gulf near the Iranian port of Bushehr.^[7]

The missile strikes Buyuk Hun in her accommodation section, killing three of her crewmen, and she has to be taken under tow by an Iranian tugboat. In response, the Islamic Republic of Iran Air Force begins patrols over the southern Persian Gulf, and Saudi Arabia announces the "Fahd Line," a line well beyond Saudi territorial waters within which F-15 Eagles of the Royal Saudi Air Force, guided by United States Air Force E-3A Senry Airborne Warning and Control System (AWACS) aircraft and refueled by U.S. Air Force KC-10 Extender tankers, will intercept any aircraft threatening merchant ships.^[9]
