It is very well written, however it is also clearly from someone who is very pro-OmegA and seems to have some insight into the program beyond what's generally known.  It could be used as a PR piece supporting OmegA, honestly.  The stuff about how OrbATK is great with security and working with contractors in that environment, and the implication the post-Zuma back-and-forth wouldn't have happened - and in fact, maybe the presumed loss of the satellite might not have happened with them - is really weak sauce.

I'm not saying this to dismiss the content - it's very good! - but there's clearly a bias as well.

Agreed, and the description of the solid propellant formulation and grain design is so detailed that it wouldn't surprise me if this guy is/was an ATK solid propulsion engineer.

I'd just like to point out that if they renamed the rocket Onega they could capitalize the letters of Orbital, ATK, and Northrop Grumman. ONeGA.

I'll let myself out.

You do realize that the most common web search result for Onega is a lake near Saint Petersburg Russia?

Somehow renaming the OmegA for a Russian lake seems far fetch. However with the current POTUS that is not totally impossible.  ::)

Northrop Grumman Omega is how I write it.  We'll find out shortly if we have to keep writing the name, at least for awhile longer.

The dual capitalization is used on its page on the Northrop Grumman website:

Yes, I know, but it (the capitalization of the last letter) is an abomination.  I refuse!

I sent him a note about an error in one of his links, plus a couple thoughts of my own.

In his response, he stated that he wasn't "an Orbital ATK person or with Northrop, so I have no horse in this race."

Doesn't rule out past association, of course. The fact that he wrote "OmegA" even in private correspondence leads me to think at least a little koolaid has been sipped. Capital "abomination" is right. ;-)

Eh, I'm still grateful that we don't have to refer to the ULA "GalaxyOne"...

Well, for someone with no horse in the race, he does seem unusually well acquainted with at least one of the horses.

Thanks for reporting his reply.

The OmegA uses a shuttle derived booster that should have some commonality with that used on SLS. I was wondering though: is it going to be more similar to the current 5-segment boosters, or the more powerful 4-segment "Dark Night" advanced boosters? I'm assuming that the composite casing is the same as on the Dark Nights, but are they using the propellant mixture from the Block I boosters or the type that they developed for the Dark Nights?
Thanks.

I read this thread and the previous thread as well as the speculation thread. I saw a bunch of references to the SLS but not a determinate answer to this question.

The new Common Booster Segment is just that - new.  It shares the same general diameter with the STS/SLS booster, but most everything else differs.  It uses a composite case rather than steel.  It is longer than an STS/SLS segment.  It is HTPB rather than PBAN.  Etc.

The general assumption is that the Common Booster Segment development effort would eventually spill over to be shared with SLS, but there's no guarantee that will happen.

Still not as bad as "SpaceShipTwo"!

NGIS OmegA launch vehicle wins USAF launch services contract

Quote
Orbital Sciences Corp., Chandler, Arizona, has been awarded a $791,601,015 other-transaction agreement for the development of a Launch System Prototype for the Evolved Expendable Launch Vehicle program

And this is a good reminder that just because one of your fellow space enthusiasts occasionally voices doubts about the SpaceX schedule announcements or is cautious about believing SpaceX has licked a problem before actually seeing proof that's true, it doesn't mean they hate SpaceX.

Interesting. They are really heading their bets here with juicy contracts...
$1 billion for Vulcan
$800 million for OmegA
$500 million for New Glenn.

Looks like Xmas came early. :)

Big solids make great weapon systems.

As long as they are not segmented, or have any requirement to be shut down in an emergency (the smallish ones on Atlas V can be jettisoned relatively easily).

So my question would be what will be powering the successor to Trident? Could this be it?

If you didn't have a skills base in solids that you wanted to preserve (or wanted to acquire) what good are they?

And note that once NASA walked away from actually funding Liberty for CCC all promises of company funded development would continue blew away like leaves in the wind.

Let's see if this goes anywhere other than the bottom line of NGL's company report.
BFS. The worlds first Methane fueled FFORSC engined CFRP structured A380 sized aerospaceplane tail sitter capable of flying in Earth and Mars atmospheres. BFR. The worlds biggest Methane fueled FFORSC engined CFRP structured booster for BFS. First flight to Mars by end of 2022. Forward looking statements. T&C apply. Believe no one. Run your own numbers. So, you are going to Mars to start a better life? Picture it in your mind. Now say what it is out loud.

Some of the technology likely, but the motor is far too large for a submarine.

CBS is a cross and combination of Castor-120 heritage and modern experiments done under the AFRL/NRL Large Class Stage programme (LCS-1 through LCS-III stage motors equal an ICBM of Peacekeeper class (civilian versions of LCS motors Castor-120XL and Castor-30XL are now about to/already flying on NGIS rockets) and other motor programmes (STS SRB et cetera).

Comparing a paper rocket (Liberty) to one that is physical (OmegA) is a quick way to try to connect two things that have nothing to do with each other.   As the article states, NGL has already poured a significant amount of money into this rocket.  So your assertion of "let's see if they self-fund it" is already moot. 

I would also say that you should listen/read the full interview on L2.  OmegA is not a paper rocket.  And, as the article also reported, even if they don't continue to Phase 2 of the contract, OmegA will still exist in some capacity.
