The Death Star Is a Surprisingly Cost-Effective Weapons System
There’s been a lot of loose talk about the Death Star lately. I want to put it into a bit of perspective.
As background, some students at Lehigh University have estimated that it would be a very expensive project. The steel alone, assuming the Death Star’s mass/volume ratio is about the same as an aircraft carrier, comes to $852 quadrillion, or 13,000 times the world’s GDP. Is this affordable?
Let’s sharpen our pencils. For starters, this number is too low. Using the same aircraft carrier metric they did, I figure that the price tag on the latest and greatest Ford-class supercarrier is about 100 times the cost of the raw steel that goes into it. If the Death Star is similar, its final cost would be about 1.3 million times the world’s GDP.
But there’s more. Star Wars may have taken place “a long time ago,” but the technology of the Star Wars universe is well in our future. How far into our future? Well, Star Trek is about 300 years in our future, and the technology of Star Wars is obviously well beyond that. Let’s call it 500 years. What will the world’s GDP be in the year 2500? Answer: Assuming a modest 2 percent real growth rate, it will be about 20,000 times higher than today. So we can figure that the average world in the Star Wars universe is about 20,000 times richer than present-day Earth, which means the Death Star would cost about 65 times the average world’s GDP.
