It might be able to air launch one of XS1 proposals. This would allow for downrange recovery on land. Between, improved latitude, small DV gain from airlaunch and downrange recovery there would be a significant increase in payload.

Even one of small LV in development eg Firefly, Electron. Would be overkill but its a LV that doesn't need to be developed from scratch.


Since Vulcan Aerospace is connected to Firefly, it would be my bet that they'll announce some sort of development partnership with them, at least.

What's interested me the most of the last couple years is how resilient these launch start ups are. You'd think microlaunch would see a bunch exiting the field due to obvious overcrowding, but more keep entering. You'd think that after 2 different rockets, Stratolaunch would be dead, but it's not. Somehow, these groups make a go of it by merging or collaborating, or at least delaying the inevitable. I mean, Dream Chaser. Everyone thought it was dead. Even Armadillo Aerospace is being reborn.

I haven't followed Firefly that much. What's the connection with Firefly?

Yeah, it's fascinating.

Makes you wonder if the next big player in the newspace launch crowd will be a company made through smaller corporate mergers.

British physics, old chap. It's undignified to belch flames and effluvia all over the pad, what. A true gentlemen's orbital conveyance lifts itself into the air unostentatiously, with the minimum of spectacle and a modicum of grace. Not like our American cousins' launch vehicles, eh?

The thing looks like the Howard Hughes "Spruce Goose" times two. The "Spruce Deuce" might be a good nickname.  ;D

From the article linked above:

Quote from: the NY Times article
“It’s an incredibly ambitious undertaking,” said Charles Beames, president of Vulcan Aerospace, the entity Mr. Allen created to oversee Stratolaunch and other space initiatives. “A really big plane means carrying anything from a really big rocket to a smaller rocket. That allows us to serve a broader set of customers.” [...]

Mr. Beames said Stratolaunch would announce new partnerships in the coming months that will fill out details about the project. He declined to say when Stratolaunch would begin test flights, but he vowed to meet a goal of Mr. Allen’s to be up and running by 2020. “Come hell or high water, you can be sure we’ll do that,” Mr. Beames said.

Paul Allen's "Vulcan Aerospace" (no connection with the planned Vulcan rocket from the United Launch Alliance) gave the Seattle Times a sneak preview of their new giant airplane-launched rocket system.

http://www.seattletimes.com/business/boeing-aerospace/paul-allens-giant-plane-takes-shape-in-the-desert-but-its-market-is-unclear/

Of special interest is the drawing of the Stratolaunch plane with a 747 and a Virgin Galactic "White Knight" superimposed on it. The Stratolaunch, is enormous.

Other quotes of interest from the article:

"It has twin fuselages, 95 feet apart, that are joined across the top by a massive wing, 385 feet from tip to tip — longer than a football field including the end zones."

"Vulcan’s concept is that this airplane will carry a rocket weighing up to 275 tons slung beneath the central part of the wing — between the two fuselages — and release it at 35,000 feet. The rocket will then launch into space and deliver satellites into orbit."

I can't find anything, even on Vulcan's home page, to say how much mass it would deliver to LEO.

When ULA debuted their name there was some barking about it violating trademark or something. That seems to have gone away. Did it just fade or did somebody make a public announcement about why it was okay?

That's because it depends on the size and performance characteristics of a rocket that hasn't been designed yet. Orbital ATK, who know a thing or two about air-launched rockets, studied the concept and ultimately parted ways with Vulcan. I don't like to be a cynic, but reading between the lines, my belief is Orbital told them how much it would actually cost and Vulcan realized the business case wouldn't close.

So now they're building a giant aircraft in search of a mythical launch vehicle than can be profitable in that niche. But if Orbital couldn't come up with a profitable concept, I don't hold much hope anyone else can.

It probably just faded away. How can you trademark the name of a Roman god from over two thousand years ago? People have been using Vulcan in business names and products long before Paul Allen decided to use it.

Build it and they will come? This airplane is a solution looking for a problem, and they must know it.
Any day with a rocket landing is a fantastic day.

Offline Bubbinski

I see the plane is taking shape. I would imagine that they would have stopped building it if they didn't have at least some uses for it. I could see the Roc flying around outsize rocket stages, satellites and other big payloads while not launching rockets.

The Roc reminds me of a design I saw of a Shuttle carrier aircraft in Dennis Jenkins' shuttle book. Could it come in handy for DreamChaser tests or X-37B successors?
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

I'm curious about this, too. I have been following Firefly pretty closely and have not seen this come up. I have been baffled about where their funding is coming from, though, and a Vulcan connection would explain a lot.

@w_mccan The company told me they require runways 200 ft wide by 12,500 ft long, but could fly on runways as short as 10,000ft.

Looks like the width of the wheel tracks is a little over the wingspan of White Knight Two, so around 45 meters, 60 meters wide runways are not uncommon.

I'm a bit surprised they went for such a wide space between the fuselages, to date air launch space vehicles have modest wingspans, and even something of over 200 tons launch mass wouldn't have a wingspan of more than 20 meters if it's a delta wing.
