The Silkworm gained fame in the 1980s when it was used by both sides in the Iran–Iraq War; both countries were supplied by China. During 1987, Iran launched a number of Silkworm missiles from the Faw Peninsula, striking the American-owned, Liberian-flagged tanker "Sungari" and U.S.-flagged tanker "Sea Isle City" in October 1987. Five other missiles struck areas in Kuwait earlier in the year. In October 1987, Kuwait's Sea Island offshore oil terminal was hit by an Iranian Silkworm which was observed to have originated from the Faw peninsula. The attack prompted Kuwait to deploy a Hawk missile battery on Failaka Island to protect the terminal. In December 1987, another Iranian Silkworm was fired at the terminal, but it struck a decoy barge instead. Prior to these attacks the missile's range was thought to be less than , but these attacks proved that the range exceeded with Kuwaiti military observers seeing that the missiles originated from the area and tracking them on radar along with US satellite imagery of the launch sites.
