Bull Doubles Supercomputer Production as Europe Races to Close AI Compute Gap

Bull Expands Angers Factory to Meet Surging European Demand

Bull, the state-owned French supercomputer maker, has reopened its expanded Angers factory with double the production capacity, a strategic move to support Europe's AI ambitions1

1

. The €80 million expansion enables the plant to assemble 12 racks per month, up from six previously, with potential to reach 24 racks next year if demand continues its upward trajectory2

2

. Chief Executive Emmanuel Le Roux revealed that Bull has received more orders this year than ever before, reflecting the intensifying race for computing power across Europe1

.

The Angers factory stands as the only facility in Europe dedicated to building supercomputers at large scale, making this expansion critical for the continent's technological sovereignty2

2

. The European Union has committed €7 billion over 2021-2027 to establish a network of supercomputers, aiming to close the compute gap with the United States and China1

1

. This investment signals Europe's determination to compete in the global AI race, where computing capacity has become as strategic as nuclear capabilities once were.

Winning the European Supercomputer Race

Bull's dominance in European supercomputing is evident in its contract wins. The French supercomputer manufacturer has secured 15 of the 18 tenders issued by EuroHPC, the EU body that co-funds Europe's network of supercomputers with member states, outcompeting rivals including Hewlett Packard Enterprise1

. This success rate demonstrates both Bull's technical capabilities and Europe's preference for homegrown solutions in critical infrastructure.

Airbus inaugurated Bull-built supercomputers in Toulouse and Hamburg this year under a five-year deal worth close to €100 million, tripling the planemaker's simulation capacity1

1

. Beyond aerospace, Bull's JUPITER supercomputer is being used by cloud operator OVHcloud and European Commission-backed Domyn for AI model training, alongside other companies Bull declined to name1

1

. These partnerships highlight how Europe's supercomputing infrastructure is becoming the backbone for frontier AI development.

Building Europe's Exascale Future

The expanded capacity allows Bull to construct two massive orders simultaneously for the first time. France's Alice Recoque supercomputer, named after computer scientist Alice Recoque, accounts for 94 racks and is being assembled alongside LUMI-AI, Finland's €388 million system and Bull's biggest-ever contract1

. Before the expansion, these two orders could not have been built side by side, executives confirmed1

.

The Alice Recoque supercomputer, an exascale system ordered for the CEA (France's atomic energy commission), is due for delivery in stages from the end of this year at a cost of €554 million to the French government and European Union1

. Bull previously built JUPITER, Europe's first exascale machine capable of performing at least one quintillion calculations per second, now running at the Jülich centre in Germany1

Strategic Sovereignty and European Components

France completed its purchase of Bull from debt-laden IT group Atos on March 31, valuing the company at up to €404 million1

. The original motive was strategic, Le Roux explained. In the 1980s, after the United States stopped shipping supercomputers to the CEA, France turned to Bull to build machines used to simulate nuclear tests1

1

. France's economy minister Roland Lescure stated, "It is imperative that France and Europe retain control over their own computing capabilities"2

2

.

The Angers factory assembles systems using Nvidia, AMD and Intel processors, or European parts, depending on customer demands1

1

. European-made components now account for 70% of the machines being built, up dramatically from 20% to 30% five years ago1

2

. This shift toward local components reduces dependency on foreign suppliers and strengthens Europe's technological autonomy.

Expanding Into AI Servers With Global Partners

Looking ahead, Bull plans to leverage the Angers facility for AI servers. Under a partnership signed with Taiwan's Foxconn in June, the two companies will manufacture Nvidia's Vera Rubin NVL72 systems at a plant in the Czech Republic, with final assembly in the Angers factory1

2

. Bull said it will name further manufacturing partners in early 2027, suggesting more collaborations are in the pipeline2

2

. The wider reconstruction of the Angers site will be finished in 2028, indicating Bull's long-term commitment to expanding European supercomputing capacity2

2

. As AI workloads continue to grow exponentially, Europe's ability to manufacture both supercomputers and AI servers domestically positions the continent to compete more effectively in the global technology landscape.
