This is a no brainer. Vinci is newer. It makes more thrust at a higher specific impulse than RL10C-1. It likely costs less to boot. Congress is not going to arbitrarily ban a rocket component produced in Germany. SLS, after all, uses German-built core tank walls. - Ed Kyle

Foreign parts are not and never have been banned, beyond simply requiring that a particular percentage of the cost of the vehicle be made by American companies. RD-180 is being banned because its from Russia specifically. America and the EU are on great terms.

New Glenn is shown with the old 5 m fairing which is no longer planned. Possibly too late to be incorporated, the New Glenn second stage will be longer as it is now using hydrolox instead of methalox. Possibly more interesting than height, would be the vehicle payload into LEO.
Orbital ATK said that the BE-3U is not one of the third stage engine candidates.
I completely agree! Details like these are important and should be fixed - this is NasaSpaceFlight.com

Stephen Clark story today titled "Orbital ATK confident new rocket will win Air Force support". https://spaceflightnow.com/2018/04/12/orbital-atk-confident-new-rocket-will-win-air-force-support/Orbital ATK has the solids, the crucial avionics, the fairing, and the launch site essentially in-hand. A no-nonsense rocket design with no unnecessary, costly, performance-robbing fancy stuff like landing legs. The key will be that mystery upper stage. - Ed Kyle
Says "all with U.S.-supplied propulsion systems", is Vinci out?

So this thing is getting the official unveiling on Monday, right?Ok... With ATKs penchant for over-the-top patriotic names for their products (Liberty anyone?), what will the name of NGL be? - Liberty (why not try again?) - Freedom - Patriot - America - Rebublic - Democracy - Constitution - WashingtonAny other suggestions?

AFAIK, the name is expected to be in line with their (Orbital - Pre ATK merger) existing naming system.
