Canadian version of the next generation ATC, CAATS achieved far more with far less ($500M vs $4.5B)

One, it is fully deployed and operational in canada. Link to NavCanada

Tow, flight data processor of CAATS is being reused in US as a core piece of the next generation ATC being built again this time by Lockeed.

So I wouldn't agree CAATS was no more successful... disclaimer: I worked on CAATS with other freaks. It's a beautiful piece of software.
