Just posted but not sure if this is new news?!

New Glenn rocket from @blueorigin will have 7-meter fairing from the start; aiming at constellations.

References to and images of the 5m fairing have been removed from Blue's site; it's not clear if they're still offering it.

Probably simplifies the aerodynamics of the whole thing? And if you going big for plenty of margin for recovery, slightly heavier fairing probably isn't a deal-breaker.

Have we seen any indication that they plan to recover the fairings? Those are going to be a lot more expensive than 5-meter fairings.

This for the initial two-stage version?

Yes 2 stage. Their website is also updated,  performance numbers are placed "under" 3 stage variant. Can't tell which is which.

As well as the 3 stage version.

The graphic still shows an expendable second stage. That is one big stage to burn up along with a large and expensive fairing too.

The economics of this will prove interesting.

Given customer response, we’re going straight to the 7m fairing and skipping 5.4m. Customers liking options the 2X volume provides.

7m also allows for large space station habitat modules.

I think LEO and GTO masses are for 2 stage. At 45t to LEO 3rd stage should capable of delivering 15t direct to GEO or DSH.

This launcher already has a very large expendable stage, and now much larger fairing than any competitor... (Fairings aren't cheap, just as SpaceX) This adds to the costs of the launcher.

So unless they really do have lots of constellation launches, this thing is going to be way over sized for almost any other payload than a LEO space station. Manufacturing 7m fairings for payloads that need much less is a big waste.

But they could certainly pull it off... Eventually launching large pieces or bulk launches will IMO be the majority of launches, so perhaps he is timing this right after all. The future will tell... :)

Not needing to make satellite as compact for launch should add significant savings to build cost.

I would expect launch prices to be competitive, unlike competition Blue don't need to recover R&D costs. While their fairing and maybe US is more expensive, the reuseable booster is lot cheaper to fly than smaller ELVs.

A statement often spoken yet not proven, almost bordering on wishful thinking. But I hope you are right.

A valid point in competition to ULA and Arianespace. Not so much in competition with SpaceX who have a reusable booster. Fairing, upper stage and the large moving ship for downrange landing are expensive to operate.

Blue think it is a valid point, but comsat owners want redundant LVs. They would only build satellite for NG if there is alternative LV with 7m fairing.

Silly question perhaps, but do they mean 7m in length or 7m diameter?

It's length. Blue Origin's graphic clearly shows same width as rocket, just like previous 5.4m fairing.
I was talking rubbish, as corrected in subsequent posts.

I'm pretty sure they mean 7 m in diameter. The rocket is 7 m in diameter.

Yeah, the 3-stage version was always pictured with a 7m fairing, and this announcement seems like a smart move, not just for pleasing prospective customers, but for simplifying the production line.

Is the cost of a fairing mainly in the labor and tooling needed to make it or the material used to make it? A 7 meter fairing, while much larger, may not cost that much more to make than a 5 meter fairing.
