New Glenn was announced in 2016. An 8 year long development process is hardly slow in aerospace. The development costs are also somewhere between three and four billion dollars. The real problem with Blue Origin is that Jeff didn't really give a damn about Blue Origin and let himself get scammed out of his money.

Given how many people work at Blue, I would suggest its more then four billion $. The Ariane 6 cost 5 billion $ or more. BlueOrigin has been spending almost 2 billion $ a year.
