Accompanying this interest in Anti-Surface Warfare, was an equivalent drive to develop precision air-to-surface and surface-to-surface weapons for antishipping roles. In particular, the Soviet Union pursued development of such weapons as a means of countering the tremendous maritime supremacy of the Western alliance during the Cold War. One of the most significant events in the history of precision weaponry occurred on October 25, 1967, when the Israeli destroyer "Eilat", patrolling off Port Said, was sunk by four Soviet-made Styx antishipping missiles fired from an Egyptian missile boat, killing or wounding 99 of its crew. The sinking of the Eilat had profound impact; one surface warfare officer remarked that "it was reveille" to the surface Navy." One senior American naval officer called the potential Styx threat his "worst nightmare."
