It all depends on on how silo'd (separated) off the Orbital and ATK parts of the company are. OATK hasn't exactly warmly embraced Antares until perhaps recently. Also, past history of an organization is no guarantee that the current employees have retained that skill-set. There are lots of examples of that.
David Thompson, Orbital co-founder, is at the helm of this merged company.  He moved Scott Lehr, from the ATK side of the house, into the lead of Orbital ATK’s Flight Systems Group, which is developing NGL (and operating Antares, Pegasus, Minotaur, etc.).  It seems to me to have been a purposeful move designed to help tear down the old walls.

No guarantees, but this merger seems to me to have many synergies.  Motor builder joins company that uses motors.

... And they don't have experience being a launch provider....

Pegasus. Taurus. Minotaur. Antares.

Thanks for pointing that out, and I've edited my post to correct my oversight. I think I was only thinking of the ATK part of Orbital ATK.
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

You're welcome. I don't think there's any doubt they could do NGL technically and operationally. It's the business case that's problematic.

The merger can also be seen as the next logical step after the "joint venture" model that Orbital and Hercules used to develop Pegasus, in which the companies shared development costs/responsibilities and profits, IIRC.

So if Pegasus was the fruit of a liaison between Orbital and Hercules, NGL will/would be the fruit of a real marriage of Orbital and ATK.

I guess Dave Thompson et al figured the Pegasus joint venture experience was positive enough the take the plunge with ATK.

I keep reading "LNG rocket" hence a rocket running on liquid natural gas (refueled and launched from a LNG ship ?)  ;D

What do you think about a expendable TSTO with BE-4U engine upper-stage? (Instead of Castor300+BE-3UEN 3th stage)
Could LOx and LNG alu or plastic COPV propallent tanks be produced using the same tooling as for the Castor X00 solid casings?

The Be3U powered US would be the most challenging for OA as they don't have LH experience. Nothing poaching engineers from ULA or Blue couldn't fix. Blue may even offer help if it results in BE3 sales.

They might not even need to poach guys from ULA, there is a lot of talent being let go in ULA's downsizing efforts that can be scooped up easily (and cheaply).

Systems Engineering position (among several) for ULA Vulcan and Orbital ATK Next Generation Launcher (NGL) USAF New Entrant Certification in Los Angeles, CA.  This is likely a job for a contractor working for the Space and Missile Systems Center (SMC) in El Segundo, CA at Los Angeles Air Force Base.

My cousin whom works at LAAFB says the position is based out of LAAFB but is a mobile position with varying job sites/locations. My cousin says that security clearance would likely be needed, but to check for the job listing in USAJobs for details (https://dod.usajobs.gov/ and http://godefense.cpms.osd.mil/).

Dates for static fire testing and operation of the heavy version:

Quote
Orbital ATK plans to compete its proposed NGL intermediate- and heavy-lift rockets in future Air Force competitions. So far, the company has passed crucial design reviews and is working toward a static fire of its four-segment heavy-lift booster in about 2022. The company expects that rocket to be operational in 2024.

Orbital ATK sees NGL as a natural progression from its smaller rockets, such as Pegasus and Antares. Antares currently delivers supplies for NASA to the International Space Station.

“We have made very incremental steps in improving our capability,” said Mark Pieczynski, vice president of business development and strategy for Orbital ATK’s flight systems group. “We’re now ready to move into the intermediate and heavy class.”

Orbital ATK and the Air Force together are investing more than $200 million to develop the launch system.

That would be great for LEO, slightly better than the 3-stage in fact. But the heavy, low impulse upper stage hurts high energy performance. With BE-4 upper the NGL 500 XL would get about 8,000 kg to GTO, while the Castor 300 + BE-3U upper stage pair would get 12,000 kg.
