So... Vulcan will not recover the two BE-4's? The ammunition age continues! They -- the legacy aerospace companies AND NASA -- continue the buggy-whip line as the cars replace the horses. Take the pork out of this game and they'll wise up real quick. Or, go the way of the buggy-whip makers.

There is no pork. Low cost is the key, not reusability. Reusability is only a means to achieve low cost.
But then again, the Navy doesn't train personnel to be knowledgeable about spaceflight.

I was wondering how Vulcan compares to the Delta IV Heavy the last of the Delta rocket family in terms of payload carrying capability? Would there be a future Heavy lift variant of the Vulcan to replace the Delta IV Heavy?

Vulcan can do the Delta IV Heavy mission with a single core and 6 SRM's with an enlarged upper stage due to come online in 2023 (after Delta IV Heavy is retired).

@torybruno any comment on this? if true, it for sure would mean Vulcan doesn’t fly in 2021.

I expect to fly in 2021. Don't know where this came from

12 months from now is September, 2020. That’s a reasonable NET date.

My brain 100% skipped the 12 month part and only read 18 months ‍♂️ yeah my bet is that Vulcan will fly in 2021. Seems like @torybruno is going to make that happen.
