October 1990: The USS Iwo Jima amphibious assault ship deployed to the Persian Gulf for Operation Desert Shield. The USS Iwo Jima docked at Bahrain shipyard for emergent repairs, but as the ship was leaving port, one hour after the propulsion plant was brought online, bonnet fasteners for a 4-inch valve supplying steam to the ship's service turbine generator failed catastrophically and 850 degree superheated steam at 600 psi escaped into the manned compartment. Nine sailors were killed instantly, one more fatally injured.
