The decade of the 1990s represents a distinctive period in American naval strategic thinking. Bounded on one side by the end of the Cold War in 1989-91 and on the other by the beginning of the era of the global war on terrorism after 11 September 2001, these were years in which the U.S. Navy of the 1990s found itself faced with a dramatically altered strategic situation. For the first time in at least four decades, the U.S. Navy had neither a peer nor a superior naval adversary; further, no credible naval adversary could be discerned in the foreseeable future.
