This article sounds like it was written by ChatGPT. That said, it's wild we were still using expendable rockets like Delta IV Heavy when SpaceX offerings are objectively better & cheaper. What SpaceX has done for the industry is nothing short of incredible.

I think that's a bit overly reductionist. This launch cost about $150m (granted, without competition from SpaceX it probably would've been much pricier). I think the going rate for a Falcon Heavy is around $120m. Not a huge difference, and it's very possible that changing the mission requirements to work with Falcon Heavy would cost more than $30m. In the past SpaceX had limitations like no vertical integration, narrower fairing, limitations with higher orbits, shorter time limits between engine burns, less accuracy in some orbits, etc. I haven't followed the launch industry as much lately so maybe thats not true anymore, but I think those things were still true when this launch was purchased ~5 years ago

Wikipedia says NRO launches are $440m, so the price difference is really really big, which is the reason why this is the last launch - not even the US Government has that kinda cash for launches.

The other reason is there's a lag of several years between when a capability is established (Falcon Heavy) and when large customers can take advantage of it. For example, we really shouldn't expect Starship to make a dent in way satellites and telescopes are designed and built until the 2030s.

Does that Wikipedia figure include the satellite?

Delta IV is notoriously expensive, but USG has plenty of DoD cash for expendable launches in general. The next block (phase 2) NSSL launches are 60% ULA Vulcan. We'll see what phase 3 looks like. I suspect it'll be far more weighted towards SpaceX to try to give ULA a kick in the pants.

DoD and USG learned through the 90s-now how screwy things get when you don't have enough competition or you can't spread your money evenly amongst vendors. They will spend the money now and indefinitely to assure they can get to space when they want to, how they want to.

That doesn't mean they're happy about it though. I'm sure they'd love if everyone was as affordable as SpaceX.

I think Wiki is wrong, IIRC this was part of a block buy of three launches for $450 million

Yes, Wikipedia says $2.2 billion for 5 launches, but the reference says $1.18 billion for 5 launches, where NROL-70 was part of a three launch buy for $467.5 million. https://en.m.wikipedia.org/wiki/List_of_Delta_IV_Heavy_launc...

Missing the most important piece of info about any NRO launch, the mission patch! Meow! https://www.nro.gov/portals/135/assets/img/L-70_Snow-Leopard...

Is it just me, but I feel like this being an NRO patch that the placement of the stars isn't just a designer's choice but potentially some cryptic meaning. If not, how boring!
