A French supercomputer factory has doubled its monthly output overnight, positioning Europe to build its two largest machines simultaneously for the first time.
Bull, the state-owned manufacturer, reopened an expanded plant in Angers on October 1 after an €80 million investment. The facility can now produce 12 supercomputer racks per month, up from six. Capacity could climb to 24 racks monthly by 2027 if demand holds.
The timing matters for Europe’s widening AI ambitions. Brussels has committed €7 billion between 2021 and 2027 to a network of supercomputers intended to close the compute gap with the United States and China.

The added space allows Bull to assemble France’s Alice Recoque system and Finland’s LUMI-AI side by side. The old plant could not have handled both in parallel.
Alice Recoque spans 94 racks. LUMI-AI, meanwhile, carries a €388 million price tag, the largest contract in Bull’s history. That system will run on AMD Instinct MI430X GPUs and 6th Gen AMD EPYC processors with 256 cores. Delivery targets the second half of 2027 in Kajaani, Finland, with roughly ten times the AI capacity of the current LUMI machine.
Chief Executive Emmanuel Le Roux reports Bull has won 15 of 18 tenders issued by EuroHPC and taken more orders this year than ever before.

European-made components now account for 70% of the machines Bull builds, a sharp jump from 20% to 30% five years ago. Customers can still select Nvidia, AMD, or Intel processors.
Under a June partnership with Taiwan’s Foxconn, Bull will also manufacture Nvidia’s NVL systems at a Czech Republic plant, with final assembly in Angers.
France completed its purchase of Bull from debt-laden Atos on March 31, valuing the business at up to €404 million. Strategic concerns drove the original acquisition. In the 1980s, after Washington cut off supercomputer supplies to France’s Atomic Energy Commission, Paris tasked Bull with building machines for nuclear test simulations.
EuroHPC signed the LUMI-AI contract on August 31, funding it equally with a consortium of Finland, Czechia, Denmark, Estonia, Norway, and Poland. Brussels continues pushing for more of the technology stack built domestically, though the most powerful AI accelerators still come from American chip designers.
