I don&#x27;t know if those are all in the same category.  For example the Army cancelled Future Combat System because it didn&#x27;t work.  Would the project have been considered a &quot;success&quot; if they had put it into production instead?<p>For my money, a real failure is like the giant BART fiasco in the 90s where they spent 80 million dollars on a new train control system that simply never existed, at all.  They had to sue General Electric to get their money back.
