> Rocket Lab's low-cost launcher ... will cost less than $5m
So if a single launcher can be built for $5 Mil, how much are the development costs going to be - and what happens to the cost-of-launch if the project can't fling 100 units a year into the sky?
I haven't a clue what it would cost to develop a new, commercial launcher from scratch - but lets make a WAG¹ at about $1Bn (which sounds incredibly low - you'd think NASA would have new launchers coming out of it's ... if they were that cheap to design and develop). then over 10 years his repayments will be about $10 M per month at 5%. So at 100 launches a year, that's a smidge over $1M per launch in finance costs. And then there's all the overheads, on top.
Personally, I'm skeptical.
