Delta IV M+ (5,2) vs the Delta IV M+ (4,2)
« on: 05/17/2016 06:14 PM »
Looking at Gunter's manifest.  There are only two more Delta IV M+ (4,2)'s and since the Delta IV M hasn't flown since 2006, ULA should look at ending the 4 meter upper stage configuration.  That should provide some cost reduction.

Arent't they ending all the line? That should lower costs. Regrettably DIVH heavy precludes LC-37 and specially SLC-6 from being put down. The latter must be specially expensive.

Since these two are set to fly within the next year or two, it seems likely that ULA has already built, or that it has at least started to build, its final 4 meter diameter upper stage.

NSF experts: Do you think ULA will publically announce finishing the final 4m DCSS, or will it just happen?

high chance that it will just happen

Could some of the recently announced ULA layoffs (discussed here) be a result of the fact that they've already finished the last 4m DCSS and closed that assembly line?

The last two Medium+(4,2) launches that I see information about are the GSSAP 3 & 4 launch in August, and the first GPS IIIA launch in May 2017.

It is Company wide and not specific to any single thing

GSSAP 3 & 4 launched on August 19.

The first GPS III launch has been delayed to NET December 2017, according to Salo's US Launch Schedule.

Does anyone know and is free to tell: Is the final 4m DCSS being fabricated now, or is the work already done?

If there's a substantial gap in time between the completion of manufacture and launch date, would the Delta stages be stored on-site in Decatur?
