SpaceX Falcon Heavy costs between $90 and 150 million and Delta IV Heavy around $350-400 million

In a tweet, Elon Musk indicated that a fully expendable Falcon Heavy, which far exceeds the performance of a Delta IV Heavy, costs $150 million, compared to over $400M for Delta IV Heavy.

United Launch says the cost of the Delta IV Heavy is $350 million.

SpaceX had said the cost of each Falcon Heavy launch starts at $90 million. But that price tag — a fraction of the cost of the next biggest rockets from competitors United Launch Alliance (ULA) and Arianespace.

Just under $400M for Delta IV Heavy, not over. The cost of the Parker Solar Probe launch is $389.1M (contract announced in 2015).

That was three years ago, before ULA canceled all medium versions of Delta IV. Future missions have all Delta fixed costs piled on, so their cost is now $600M+ for missions contracted for launch after 2020. Nutty high.

Elon is talking about United Launch Alliance’s plan to replace its Delta and Atlas rockets with a new, powerful booster called the Vulcan rocket. Originally planned for a launch in 2019, the Vulcan rocket’s maiden launch now will probably slip into mid-2020 at least. But Musk clearly believes the test flight and Air Force certification process will delay that quite a bit longer for the Vulcan.

Some were saying 2020 for the switch to Vulcan-centaur+ for heavy lift not stick with Delta.

Maybe that plan works out, but I will seriously eat my hat with a side of mustard if that rocket [Vulcan] flies a national security spacecraft before 2023.
