Considering it is a freighter, that would be understandable. I saw nothing there about being used as a landing platform. Where did that come from? The NG production facility is at the Cape. There is no need to transport rocket components on a ship. Assuming ULA selects Be-4, the engine production is in Alabama, but those easily fit on trucks. The rocket transportation is likely because landing platform isn't already something in existing licensing I would bet. It WILL transport rocket components back to FL. From the Atlantic. Also it looks sorta like what they were imagining (forward bridge, anyway): Quote Link to post Share on other sites

Pretty routine in the defense contracting world to collaborate with competitors. I mean, that's what ULA *is*. Boeing and Lockheed Martin collaborating on a business project.

RedKraken 542 Posted September 28, 2018 Share Posted September 28, 2018 Some cool work on trying to estimate the BE-4 performance : https://forum.nasaspaceflight.com/index.php?topic=45518.0 They are clustering around 312s - 345s for the isp based on the geometry, cycle, pressure and thrust. This estimate puts it just over RD-180 series performance at 311-337s. The TWR is a mystery. It is a massive powerhead. I figure it may be somewhere near 80:1 like the RD-180. Maybe more since the chamber pressure is so low : 13.4MPa vrs 26.7MPa on the russian engine. Less metal needed around the chamber. If so, the 240t thrust engine would have a mass of about 3t.
