>Cost and schedule overruns are a staple of developing new technology and complex systems. It's very difficult to estimate time and budget for those things.
I'd be more sympathetic if SLS had more new technology.
They're using actual engines that previously flew on Shuttles.
And sure - there's a few changes - the SRBs have 5 segments, there's new insulation, etc. But nothing that should have caused the expense and delay that we're seeing.
Heck - the cost overruns and delays with the mobile launch platforms ML-1 and ML-2 are absurd and there's absolutely nothing new there - they're just steel towers with piping.
