We too would have an entire new generation of Future Combat Systems if Congress hadn’t made it a welfare program and laden it with every enviro-nut agenda. Instead we spent more than enough to develop all new vehicles and didn’t get even one. But plenty of individuals walked away richer for the experience.
I have to point out that the Army did itself no favors in that program either with ever-increasing lists of requirements. According to a 2014 USD(AT&L) report, the Army leads the other services in the number of acquisition programs that have been killed due to cost overruns.
Business as usual.
