Weird Fact of the Day: B-52s Versus Cruisers

The B-52 goes back to my childhood, and is still around.  From an article arguing that the Air Force should have replaced its engines with more fuel-efficient modern ones, comes this fact:

Since today’s B-52s rolled off the Wichita production line, the Navy has launched and scrapped two classes of destroyer and four cruiser classes, and that comparison makes a $550 million Long Range Strike Bomber look a little more digestible.

 Back in WWII the cost relationship and the longevity comparison between a bomber and a destroyer or cruiser would be one-sided in favor of the ship.  I suppose that's an indirect measure of the cost of electronics  versus the cost of people.
