Even if it ends up as the Worlds largest water bomber it would be fun ( California seems to need it these days).
Reading around the subject there does seem to be more than a whiff of the US military being interested as an instant response 'anywhere' sat' launcher.

I don't think it's even remotely capable of conducting any sort of maneuver that would be required by a water bomber. IMHO structural integrity (not so much overall lifting strength, but inherent weakness with the unsupported twin fuselage design) is going to limit this thing to a single specific task. I think she's forever going to be a straight/level (and zero turbulence) air frame.

At the end of the day, I still like the Spruce Goose analogy. It will likely be equally as epic to see her take to the skies though.

As the title says they have abandoned building their own air launched rocket.Now relying only on a small and expensive rocket that is already air launched nad has never gained traction in the marketplace ( launching 3 won't make it better if anything less flexible).
But yet...They continue with the Stratolaunch development.Achieving first Flight must be very close indeed.
But why?
It may be in their founders will ' of wishes' which is known to exist.
Some others say the US military are involved in this programme so they can 'instantly' launch a small spy satellite whenever/wherever necessary.Its possible I suppose.
But other than that it's an answer without a question.Hard to know what else it could be used for.
Any suggestions?

The same information as the previous thread but in a different article.
It has a photo with the front wheels up during the high speed taxi test,

It certainly appears the focus is now on the launch vehicle rather than producing vehicles to be launched. That seems to be the way the article pointed. If that's the case and the first example proves dependable and flexible in terms of the kinds of vehicles that can be launched, it "might" open the door to further examples being built.

Sorry to disagree.Whether it flies or not is somewhat immaterial if there is no ( Spruce Goose) market for it.I have been correctly corrected that it would not have the manoeuvrability to become a giagintic waterbomber ( which CA increasingly need). Can't think ( other than the summonsed military use) of what you would do with such an aircraft sadly.
If one is 'simply' lobbing' up the occasional small sat' one airacft is more than enough.Actually not sure they ever envisaged building more than one the way they built it.
Could be an oversized 'spare' for Richard Brandon's project I suppose,both built by the same people I believe.

I suppose it depends on how much ground clearance you have for cargo. Can’t find many reliable specs. Perhaps it could be used for rocket transport. Moving Falcons from Hawthorne to TX to Florida or Falcon Heavy components. For that matter maybe it could transport Delta or Atlas/Vulcan rockets. It would cost a lot more than current transport methods, but maybe it would be less headache and certainly faster than a truck over land or a bardge through Panama.

That's a lateral thought.Hope it finds a use.I guess the fact that they appear to want to see it fly suggests they see it having a use.Just find it hard seeing they will use that little rocket.It already launches perfectly well off a Tristar ( which I imagine is cheaper too).
Regarding RB.It seems his tourist rocket is somewhat vertically challenged not making the Karman line.Perhaps this aircraft could give him an extra 10k feet altitude on T/O .Would make a hell of a difference overall.

The TriStar won't be flying for a whole lot longer. That airframe has a lot of age and parts for that frame are getting hard to come by. I suspect that this can find some business covering for that platform.

I still think that they need to make a large cargo pod for it so that it can be used for moving outsized cargo in addition to rocket launches.

Cargo would be great but I think it won't work. It is too limited in the facilities that it can work on:
385' wingspan
Fuselage/landing gear width of over 100' (can't find the exact dimension)
And a working runaway length of 12,000'

That’s why I think the only viable cargo is out-sized stuff that can move more quickly theough the air than on the ground. If they can fly with an F9 booster (or atlas/Vulcan /delta) from Cali go TX to FL they might have a use for the plane. If the length of those booster stage makes it impossible, then this thing has no practical use at all.

Is there any status update about their first flight available please? Their tweet is quiet for a month now after those high speed taxi tests. Anything happening right now?

If a rocket isn't made to be transported like that then its structure wouldn't resist being hanged by the middle.

Fair point. Just spitballing ideas to come up with a use for this thing.

Par for the course - really worried about this thing getting scrapped at this point. :(

Maybe she takes off to set a record... but I think her commercial case is closed, hence the DRAMATICALLY slowed rate of testing. I still think they either discovered a catastrophic design issue and/or it just doesn't save enough $$ at a given payload to justify the program any longer. Lips sealed for PR and investor/legal reasons.

Still hoping for the best and first flight. They seem to have reduced their staff significantly. Not a good sign during first flight preparations.
