In the early 60s, the US Navy named two Polaris ballistic missile submarines for Robert E. Lee and Stonewall Jackson respectively.
The naming convention for these vessels was that they would honor “Americans who made major contributions to freedom.” Others so honored included George Washington, Abraham Lincoln, Patrick Henry, etc.
41 for freedom ballistic missile submarines.
This was around the time of the Civil War Centennial, which, in many ways, was the high water mark of the Lost Cause mythology. I remember the almost Disneyesque aspect of the celebrations, with scrupulous attention to the need to honor both sides equally and the paramount need to emphasize national reconciliation and unity on those terms. Even at the time, I thought is was a farce, and most scholars today (and many then) tend to agree.
