In my opinion, planned cessation of production of RD0110 in Russia - a good reason for license purchase.

good thinking Dmitry.  ;)

I agree, but would Russia allow and agree to license purchase of RD-0110 engine and would their be issues raised regarding ITAR.

Well, Russia already sold NK-33 and RD-180 engines in the USA. Why to it also not to sell RD0110, having money from its license production? ::)

You really should get L2. There's some amazing info directly from senior officials from OSC regarding the Stratolauncher and how it could help the Antares.

How about adding a third nk 33 on the first stage and a reusable upper stage with an inflatable heat shield.What shut down Kistler was  lack of money not technical problems.

In my opinion, such change in a design of the rocket won't pay off because of high expenses and low rate of starts.
Let's ask about it doctor Antonio Elias ;)

I am not talking about a fast modification  a slow evolution one step at a time . I honestly thing orbital have scored an ace with that rocket .See how slow it rose off the pad nice smooth launch with low G,s .

I am sure the max G's were over 5

Well within human tolerances .No shaky solids this launcher should find plenty of work .All that is needed is to replace the Caster with a liquid stage to man rate it .
As I said they have scored an ace :)

If my memory serves me, Russian man-rating requirement is that G-load shall not exceed 4Gs during nominal ascent. I'm sure NASA's requirements are even more restrictive (or maybe not since they seem to be perfectly fine with flying astronauts onboard rocket certified to Russian man-rating standards).

I remember I've asked this question here, and got response that it was around 5Gs near end of first stage flight.

Straight from the good doctor's mouth, 5.3 g's near t=205 sec:

Dmitry is correct; Antonio has said that Antares was designed to be profitable at a low launch rate. Making it more expensive (and reducing payload) at a low launch rate won't help.
