Honestly, the Delta IV is the biggest fuck-up in the history of rocketry; It is:

-Horrifically inefficient, due to the first stage using hydrolox
-Incredibly expensive (350M $)
-Weak and anemic, only managing 28 370kg into LEO, 8 000 GTO
-The size of a Falcon Heavy, yet half the payload capability, more than double the cost (if FH is expended)
-Latest rocket has been standing on the pad for two months now, and will stand there for atleast two more weeks

What the hell were they thinking when they decided that a low density, low power, high ISP vacuum optimized propellant would be good for a first stage?
