Disclaimer: At my previous job, I was several degrees disconnected from SCA/radio contracts (worked on test sets for those radio systems).

Being over budget, late, and not meeting requirements seems to be an infectious quality. However, it's not like many companies are set up to deal with winning these contracts. Do you choose the company that's more likely to have a more complete product but possibly be unable to support it in a couple of years? Or the one that can do decades of support (including replacing obsoleted hardware) but has a reputation for being late, overbudget, and half done?
