With the recent relaunch of a falcon 9, I'd say it's better late than never. However Ariane 6 might now be obsolete before it has even flown.

COLORADO SPRINGS — The European Commission will commit to buying at least five Ariane 6 and two Vega C launches per year when both rockets are in operation, Elzbieta Bienkowska, the European Commission’s lead space commissioner, said Wednesday.

“We observe very closely the ongoing revolution in the launcher market, especially here in the United States, around the principle of reusability,” she said. “Europe’s answer is the development of the next-generation of cost effective, reliable and competitive European launchers: Ariane 6 and Vega C.”

Ariane 6's first flight is planned for 2020! But we're already building the plant where we'll assemble the launcher's main stage!

There's a time lapse video with the tweet but seems to be just groundworks at this point.

Note: this is the same Airbus subsidiary that also constructs the engine frame for stage 1 of Ariane 5, the 1/2 interstage for Vega and has constructed the 1/2 and 2/3 interstages for Ariane 1 thru 4.

This is a SpaceX fairing, not an Ariane 6 item.

my apologies, there was a cache issue on my browser, so the 3rd image in FutureSpaceTourist's post showed up as a photo of a recovered F9 fairing for me.

ArianeGroup silently upgraded the Ariane 6  ;)

On the their website the payload performanc is now listed as "up to 12 tons to GTO"

The Materials Testing Institute University of Stuttgart received a tech demonstrator of the P120C booster for Ariane 6.

Diameter 3.5 meters, height 6 meters. It will be filled with 56,000 liters water and then pressure tested to destruction.

The Technology Demonstrator

The European Space Agency (ESA) is developing a new-generation launcher, Ariane 6, and the Materials Testing Institute University of Stuttgart will contribute its part. The key verification test of the future solid-rocket booster – based on fiber composite for the first time – will be performed in our 32 meters deep inspection shaft.

Verification test Ariane 6

The verification test is supposed to reassure that the new-generation booster will meet the requirements of a rocket launch. It is devided in two parts. After the booster has been filled with water, two different pressure levels are generated in the first part and the measured values are recorded. In the second part, the water pressure is gradually increased until the test specimen fails.
Before the actual verification test can take place, some preparations have to be made. To analyze the material and component behavior in detail a lot of measurement instrumentation is needed.

As written crosspost from the discussion topic.
Today at the ESA pavilion at the Paris Airshow, there was a live roundtable discussion about the fixed institutional procurement of launches from Arianespace. Link to video
The participents were representatives of: the EU, ESA, France, Germany & Italy, EUMETSAT and Arianespace.

Discussions belong in the discussion threat.

20 06 2017 AEROSPACE
GKN DELIVERS REVOLUTIONARY ARIANE 6 NOZZLE TO AIRBUS SAFRAN LAUNCHERS

- First nozzle in flight configuration with laser-welded technology and additively manufactured structures
- 90% reduction of component parts, 40% reduction of costs and 30% reduction of production time
- Dedicated manufacturing center of excellence to be opened  in Trollhättan, Sweden in 2018

GKN Aerospace has delivered the first advanced Ariane 6 nozzle (SWAN) to Airbus Safran Launchers in France for the Vulcain 2.1 engine. The new state of the art nozzle, which measures 2.5m in diameter incorporates innovative technologies with higher performance, lower lead times and substantial cost reduction. Large scale use of laser welding and laser metal deposition (additive manufacturing) for key structural features resulted in 90% reduction of component parts, taking it down from approximately 1000 parts to 100 parts. A demonstrator nozzle has already been successfully trialled in a full-scale engine nozzle test as part of the European Space Agency’s Ariane  Research and Technology Accompaniment (ARTA) Program. Now the flight configuration nozzle will be mounted in France to the Vulcain 2.1 engine for a test in Germany. The Ariane 6 is scheduled to enter service in 2020. Airbus Safran Launchers is the prime contractor and GKN’s customer in this development program funded by the European Space Agency.

GKN Aerospace will manufacture the nozzle in a new highly automated manufacturing centre in its facility in Trollhättan, Sweden, which is scheduled to open in 2018.

In total GKN Aerospace will provide five complex sub-systems for each Ariane 6 rocket, including four turbine assemblies for the two engines, generating power for the hydrogen and oxygen fuel systems.

Sebastien Aknouche General Manager Space, GKN Aerospace Engine Systems said:

“We are proud to be part of the Ariane 6 team. The advanced nozzle manufactured with breakthrough technologies is a true innovation. With the support of the Swedish National Space Board, we participated in the initial engine demonstrator programs. This allowed us to work with our customer to prove the great added value that innovative technologies like additive manufacturing have for the design and production processes in the space and aerospace industry.”

GKN Aerospace’s Space business unit, in Trollhättan, Sweden, has been active in the Ariane program from its inception in 1974 and has made over 1,000 combustion chambers and nozzles as well as over 250 turbines for the Ariane rocket to date. Today it is the European centre of excellence for turbines and metallic nozzles, having contributed to the programme at every stage of initial research and development through cooperation with academia to the serial production.

- 90% reduction of component parts, 40% reduction of costs and 30% reduction of production time

That's good news. Which is the share of the total Ariane 5 cost is due to the Vulcain 2 currently?

From here: https://www.ariane.group/en/commercial-launch-services/ariane-6/prometheus/

Quote
Its aim is to lower the production price of the Vulcain® engine by 90%, meaning that this future engine would cost only 1 million euros, as against just over 10 million for the Vulcain®2 engine fitted to Ariane 5
