| No tracked project linkSES | OHB | Supplier | Satellite bus Development and manufacture of eighteen satellite platforms for the SES-led MEO segment of the European IRIS² secure-connectivity system. Details & project milestonesDevelopment and manufacture of eighteen satellite platforms for the SES-led MEO segment of the European IRIS² secure-connectivity system. The source describes contract value as nearly one billion euros, not an exact USD 1,117,200,000 (EUR 1 billion); no exact amount is entered. August 31 is the retained publication date, not a disclosed contract-signing date. August 6 is the programme implementation-phase start. The contract is signed; platform delivery, first satellite launches planned for 2029 and first services planned from 2030 remain future milestones. Eighteen platforms are this order, not the full 348-satellite IRIS² system. No compute or data-center capacity is asserted. Disclosed buyer: SES.

Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
