Transport yourself to another time. The nation has completed a distant and costly ground war that was supported at home but experienced enough unpopularity that it caused a change in political leadership. The national economy in the aftermath of the war is increasingly under pressure from the rising costs of social programs. In the midst of the subsequent declining defense budget, a new global competitor is emerging with rapidly growing military capability. As the nation’s armed forces downsize, debate is increasing on roles and missions of the services and their consequent shares of the dwindling funds. Within the Navy, there is further debate over the merits of having smaller, less capable, but more numerous ships to better provide global presence versus larger, more capable, but fewer ships to maintain military advantage over the rising competitor. The pursued solution, as is often the case, is new technology.
You may have been thinking of the United States a few years into the future. Think Great Britain a century ago.
